Fire ant poisoning: disease-characteristics research report

Scope and evidence standard (6 October 2026). “Fire ant poisoning” is best treated as an acute, exposure-dependent sting/envenomation injury, not a single inherited disorder. The best-described agents are Solenopsis invicta (red imported fire ant), S. richteri (black imported fire ant), and, in some regions, S. geminata. Direct venom toxicity and allergic reactions can occur separately or together. Much of the precise human evidence concerns imported fire ants; findings for one species should not automatically be transferred to another. This synthesis prioritizes original human cohorts, an experimental mouse study, and 2023–2024 reviews; DOIs are supplied where the retrieved sources did not verify PMIDs. Suggested ontology labels below are mappings for curator verification, not assertions that a particular accession exists. (mcmurray2025fireantvenomanaphylaxis pages 2-3, sukprasert2012characterizationofthe pages 1-3, dioguardi2024therapeuticpotentialof pages 4-6)

1. Disease information and identifiers

A worker ant anchors itself with its jaws and injects venom with an abdominal stinger, potentially stinging repeatedly. The characteristic presentation is immediate local burning pain and erythema, followed by wheal, swelling and sometimes a sterile pustule. A susceptible person can instead, or also, develop a rapid systemic allergic reaction, including anaphylaxis. Appropriate synonyms include fire-ant sting, fire-ant envenomation, imported-fire-ant sting reaction, red-imported-fire-ant envenomation and, specifically for immune disease, fire-ant venom allergy; “bite” is common colloquial usage but is less precise for venom injection. (dioguardi2024therapeuticpotentialof pages 2-4, dioguardi2024therapeuticpotentialof pages 4-6, rodrigo2018immunotherapyinanaphylaxis pages 1-2)

Identifiers: The requested MONDO:0100341 is a candidate supplied by the requester, not independently verified as a current MONDO record in the retrieved material. MeSH D007299, “Insect Bites and Stings,” is verified in a ClinicalTrials.gov record and is broader than fire-ant poisoning. An exact species-specific ICD-10-CM/ICD-11 code, OMIM entry, Orphanet entry, disease-specific MeSH descriptor, SNOMED CT concept and formal HPO association were not independently verified; do not fabricate them. One human prevalence study found that using nonspecific Hymenoptera allergy ICD-10 codes alone substantially misclassified patients: only 36 of 150 reviewed records documented actual venom anaphylaxis. (NCT00435552 chunk 1, mcmurray2025fireantvenomanaphylaxis pages 5-7)

Data provenance: This entry synthesizes aggregated published cohorts, an individual-patient clinical cohort, experimental work and review literature. It is not a claim to have accessed the knowledge-base user's EHRs. A TRICARE analysis used administrative records with sampled chart validation, whereas a Brazilian immunotherapy study followed 33 clinically identified patients. (mcmurray2025fireantvenomanaphylaxis pages 1-2, watanabe2022clinicalandlaboratory pages 1-4)

2. Etiology, risks and protective factors

Necessary cause: Contact with, and venom injection by, a stinging fire ant. S. invicta venom is predominantly water-insoluble piperidine alkaloids, particularly solenopsins; smaller protein fractions include the allergenic Sol i 1–4 components. Estimates of approximately 95% alkaloids and 10–100 ng protein per sting come from compositional literature, not a measured dose for every patient. S. geminata has a related but nonidentical allergen, Sol gem 2. No infectious organism or primary human germline mutation is required. (sukprasert2012characterizationofthe pages 1-3, dioguardi2024therapeuticpotentialof pages 4-6)

Exposure risk rises with outdoor work, agriculture, infested urban green space, nest disturbance, repeated stings and expanding ant range. Immobility, very young or older age, cognitive impairment and flooding can increase opportunities for high-dose encounters; these are exposure/vulnerability factors, not proven fire-ant-specific genotype effects. Systemic mastocytosis is an important host condition to consider after severe reactions: among 97 persons with systemic mastocytosis or monoclonal mast-cell activation syndrome in a selected U.S. cohort, 14 had a fire-ant anaphylaxis history. This selected denominator must not be treated as risk among all stung persons. Existing sensitization permits IgE-mediated responses on subsequent exposure. (chen2026analysisofthe pages 2-4, mcmurray2025fireantvenomanaphylaxis pages 7-9, mcmurray2025fireantvenomanaphylaxis pages 9-10)

Protection is principally avoidance of occupied nests and repeated stings, rapid recognition and treatment of systemic reactions, ready access to prescribed epinephrine for people with prior anaphylaxis, and specialist whole-body-extract immunotherapy after an appropriate allergic evaluation. Evidence for a protective human allele, diet, supplement or established pharmacogenomic intervention specific to this injury was not retrieved. The plausible gene–environment interaction is that mast-cell disease alters the response to venom exposure; it does not turn envenomation into a Mendelian disorder. (watanabe2022clinicalandlaboratory pages 1-4, mcmurray2025fireantvenomanaphylaxis pages 7-9, rodrigo2018immunotherapyinanaphylaxis pages 4-5)

3. Phenotypes and quality-of-life impact

Clinical phenotypes occur at any age after exposure, with acute onset and highly variable severity. Immediate pain/wheal can evolve into local pruritus and a sterile pustule within approximately a day; large local reactions can last up to 72 hours. Systemic urticaria, respiratory compromise and cardiovascular shock require urgent assessment. Severe multi-sting toxicity, reported complications including rhabdomyolysis and acute kidney injury, and unusual eye injury should be documented separately from uncomplicated pustulation. Neither behavioral change nor a characteristic routine blood-test abnormality is an obligatory manifestation. (dioguardi2024therapeuticpotentialof pages 4-6, rodrigo2018immunotherapyinanaphylaxis pages 1-2, guillet2022partiinsect pages 3-4, chen2026analysisofthe pages 1-2)

The largest retrieved symptom compilation is a 2026 China analysis combining published reports, news and hospital cases. Its categories overlap and describe recorded cases, not the prevalence among all stung residents. The paper's results text and inspected image support the following counts; suggested HPO labels require curatorial verification. (chen2026analysisofthe pages 2-4, chen2026analysisofthe pages 6-8, chen2026analysisofthe media 303ec5e0)

Table: Clinical phenotypes among 8,749 assembled fire-ant sting cases reported by Chen et al. (2026). These mixed-source frequencies are descriptive rather than population-based; the corrected projected systemic-allergy count is 52,600, not the abstract's erroneous 526,000.

For knowledge-base annotation, classify itching/pain and dizziness/headache as symptoms; wheal, pustule, swelling, urticaria, fever, lymphadenopathy and speech impairment as clinical manifestations; hypotension/shock as severe signs; and, if clinically measured after massive envenomation, raised creatine kinase or renal dysfunction as complication-associated laboratory abnormalities rather than universal biomarkers. Candidate HPO labels additionally include Edema, Erythema, Hypotension, Dyspnea and Bronchospasm, where documented for the patient. Reliable age-stratified phenotype frequencies, quantitative EQ-5D/SF-36 scores and per-phenotype disability estimates were not established. Pain, itching and pustules may disrupt sleep or work; anaphylaxis can acutely interrupt normal function and creates a risk of future-exposure anxiety, but those quality-of-life effects should not be assigned invented fire-ant-specific numerical values. (watanabe2022clinicalandlaboratory pages 1-4, chen2026analysisofthe pages 1-2, dioguardi2024therapeuticpotentialof pages 4-6, chen2026analysisofthe pages 6-8)

4. Human genetics and molecular annotations

Causal human genes, pathogenic variants, ACMG classifications, inheritance, penetrance, carrier frequency, founder effects and chromosomal abnormalities: not applicable as defining features of this venom injury. The antigen names Sol i 1, Sol i 2, Sol i 3 and Sol i 4 describe ant venom proteins, not HGNC symbols for human disease genes. Sol i 1 has phospholipase activity, Sol i 3 is antigen-5-related, and Sol i 2 is an important allergen; S. geminata Sol gem 2 was characterized by electrophoresis and mass spectrometry as a native dimer. (mcmurray2025fireantvenomanaphylaxis pages 2-3, sukprasert2012characterizationofthe pages 1-3)

Relevant host modifier, not the cause of a sting: Acquired mast-cell disease frequently carries somatic KIT p.D816V. In the selected 97-person mastocytosis/monoclonal mast-cell activation cohort, 82/97 were KIT p.D816V-positive; this is not a prevalence estimate for fire-ant poisoning, nor evidence that the variant predicts an individual's reaction. Specific germline susceptibility loci, protective variants, epigenetic signatures and modifier allele frequencies for fire-ant poisoning were not established. Routine gene panels or genomic sequencing are therefore not disease diagnostics; investigation of mastocytosis, potentially including KIT testing, is a separate clinically indicated evaluation after concerning anaphylaxis. (mcmurray2025fireantvenomanaphylaxis pages 5-7, mcmurray2025fireantvenomanaphylaxis pages 7-9)

5. Environmental and lifestyle information

The pertinent environmental agent is injected Solenopsis venom, with risk strongly shaped by ant distribution, nest density and human contact. Farmland, lawns and green spaces, outdoor activities, and disturbance of mounds are more relevant than tobacco, alcohol, exercise or diet as putative causes. Neither ionizing radiation nor an infectious agent is part of the established causal definition. Invasion surveillance and ant control constitute exposure reduction rather than treatment of an already injected toxin. Suggested chemical-entity labels, pending ChEBI accession verification, are solenopsin A, piperidine alkaloid, histamine and epinephrine. (dioguardi2024therapeuticpotentialof pages 2-4, chen2026analysisofthe pages 2-4, dioguardi2024therapeuticpotentialof pages 4-6)

6. Mechanism and pathophysiology

Ordered causal chain. The two main downstream branches should remain distinct:

1. Ant contact and sting leads to venom deposition in skin; repeated stings lead to greater exposure. (dioguardi2024therapeuticpotentialof pages 2-4)
2. Venom alkaloids lead to direct local cytotoxic and inflammatory injury; this results in immediate burning, erythema and edema. The exact molecular target in human sting lesions is incompletely established. (sukprasert2012characterizationofthe pages 1-3, dioguardi2024therapeuticpotentialof pages 4-6)
3. Local injury leads to neutrophil/eosinophil infiltration, fibrin deposition and basal tissue necrosis, resulting in a characteristic, often sterile pustule; this is the direct-toxicity branch and does not require prior IgE sensitization. (sukprasert2012characterizationofthe pages 1-3, dioguardi2024therapeuticpotentialof pages 4-6)
4. In parallel, venom proteins lead to antigen presentation and type-2 sensitization; experimental mouse evidence demonstrates dendritic-cell activation, IL-4, eosinophil recruitment and eotaxin, whereas the full sequence to venom-specific IgE in a particular human is partly inferred from established allergy biology. (zamithmiranda2018theallergicresponse pages 6-7, zamithmiranda2018theallergicresponse pages 1-2)
5. In a sensitized host, re-exposure leads to IgE-dependent mast-cell/basophil activation and mediator release; this results in generalized skin symptoms and, when severe, airway obstruction, bronchospasm or circulatory collapse. Specific cellular intermediates and mediator concentrations have not been measured for every fire-ant clinical phenotype. (zamithmiranda2018theallergicresponse pages 1-2, chen2026analysisofthe pages 1-2, mcmurray2025fireantvenomanaphylaxis pages 7-9)
6. Heavy multi-sting exposure may lead to systemic toxic injury, resulting in reported muscle injury and kidney dysfunction; exact human dose–response, cellular target and contribution of allergy versus direct toxicity remain uncertain. (chen2026analysisofthe pages 1-2, guillet2022partiinsect pages 3-4)

Experimental resolution: In male BALB/c mice, venom-protein sensitization followed by challenge 14 days later caused footpad swelling, IL-4 production and eosinophilic recruitment; coadministration of venom proteins with ovalbumin increased ovalbumin responses, whereas heat-treated venom lost this adjuvant activity. The authors measured dendritic-cell MHC-II/CD86 up-regulation. These findings establish a protein-associated type-2 mechanism in an induced mouse model, not a validated predictive molecular signature in patients. Do not claim that IL-5, IL-13 or venom-specific IgE were quantified in that study on the basis of the retrieved results. (zamithmiranda2018theallergicresponse pages 6-7, daniel2018theallergicresponse pages 6-9, zamithmiranda2018theallergicresponse pages 7-8)

Annotation suggestions: GO biological-process labels inflammatory response, response to toxin, antigen processing and presentation, type-2 immune response, mast-cell activation, eosinophil chemotaxis and tissue necrosis; CL cell-type labels keratinocyte, neutrophil, eosinophil, dendritic cell, CD4-positive T cell, B cell, mast cell and basophil. These describe implicated or biologically plausible participants; not every cell type has been demonstrated in both human lesions and mouse models. Do not assert Wnt, MAPK, mTOR or PI3K–AKT as the established causal signaling pathway of clinical envenomation merely because isolated solenopsin has been investigated as a pharmacologic lead in unrelated cell and cancer models. No validated patient-specific transcriptomic, proteomic, metabolomic, lipidomic, spatial, single-cell, CRISPR-screen or epigenomic disease signature was retrieved. (zamithmiranda2018theallergicresponse pages 6-7, dioguardi2024therapeuticpotentialof pages 6-8, dioguardi2024therapeuticpotentialof pages 4-6)

7. Anatomical structures

Primary site: skin at the sting site, involving epidermis and superficial dermis; local swelling and pustules can occur on any exposed surface. Proposed UBERON label skin of body and CL labels keratinocyte, dermal immune cell, neutrophil and eosinophil require exact accession validation. Anaphylaxis can affect skin/mucosa, upper and lower airways and the cardiovascular circulation; reported complications involve skeletal muscle and kidney. Rare direct corneal stings affect the ocular surface. The site depends on exposure rather than a disease-specific left–right preference: lesions may be unilateral, bilateral or multifocal. (chen2026analysisofthe pages 1-2, dioguardi2024therapeuticpotentialof pages 2-4, dioguardi2024therapeuticpotentialof pages 4-6)

At subcellular level, secreted venom protein in extracellular tissue, surface immunoglobulin-receptor signaling and antigen processing by immune cells are mechanistic concepts; no fire-ant-specific diagnostic mitochondrial, nuclear, lysosomal or ER lesion was verified. Candidate GO cellular-component labels extracellular region, plasma membrane and antigen-processing compartment should be curated against individual experiments rather than assigned indiscriminately. (zamithmiranda2018theallergicresponse pages 6-7, zamithmiranda2018theallergicresponse pages 1-2)

8. Temporal development

Onset is acute after a sting at any life stage, not congenital. Burning and wheal are immediate; pustulation commonly develops by approximately 24 hours, while local pruritus and large local swelling can last up to 72 hours. The potential for rapid anaphylaxis makes the period immediately after a systemic reaction critical for emergency treatment. Most uncomplicated localized injuries are self-limited; persistent lesions, secondary infection, ocular injury and recurrent reactions on later exposures change the course. There is no recognized early/intermediate/end-stage classification, genetic anticipation or permanent remission guarantee after allergy treatment. Longer-term outcomes and relapse rates after stopping imported-fire-ant immunotherapy remain less well quantified than short-term field-sting outcomes. (dioguardi2024therapeuticpotentialof pages 4-6, rodrigo2018immunotherapyinanaphylaxis pages 1-2, guillet2022partiinsect pages 3-4, watanabe2022clinicalandlaboratory pages 13-16)

9. Population, epidemiology and inheritance

In a U.S. TRICARE direct-care population of 2,835,948, investigators estimated 1,370 fire-ant-anaphylaxis cases, 0.048% or approximately 48 per 100,000, and 0.085% or 85 per 100,000 within 14 states colonized by fire ants. These are estimates of anaphylaxis prevalence in a particular administrative population, not all sting poisoning, and are sensitive to coding, prescribing and military-associated exposure. In that cohort, 878 fire-ant immunotherapy prescriptions represented 45.9% of individual Hymenoptera immunotherapy prescriptions. The selected mastocytosis cohort included 14/97 persons with fire-ant-anaphylaxis history; 14/43 among participants who had experienced any anaphylaxis. (mcmurray2025fireantvenomanaphylaxis pages 1-2, mcmurray2025fireantvenomanaphylaxis pages 5-7, mcmurray2025fireantvenomanaphylaxis pages 7-9, mcmurray2025fireantvenomanaphylaxis pages 9-10)

The China compilation counted 8,749 selected, documented cases from 2004–2024, and modeled about 699,224 stung people annually, 8,181 with shock and 209 deaths; these modeled totals must not be reported as observed surveillance counts or reliable national incidence. The paper's body estimates 52,600 systemic-allergy presentations annually (7.52% of approximately 699,224): its abstract incorrectly prints 526,000, an approximately tenfold discrepancy. Its 120-million-person figure describes a broad population potentially threatened by invasion, not the denominator for the modeled annual sting estimate. Sex ratio, age-specific annual incidence and reliable global fire-ant-attributable mortality are not established by these datasets. Geographic exposure differs sharply: U.S. colonized states, mainland China, South America and recently established S. invicta in Sicily require separate interpretation. Inheritance, penetrance, carrier frequency, consanguinity and founder effects are not applicable to the injury itself. (chen2026analysisofthe pages 1-2, chen2026analysisofthe pages 2-4, mcmurray2025fireantvenomanaphylaxis pages 7-9, chen2026analysisofthe pages 6-8, dioguardi2024therapeuticpotentialof pages 2-4)

10. Diagnostics and differential diagnosis

Acute diagnosis is clinical: document the observed insect or mound, time and number of stings, stereotypical lesions, vital signs, respiratory symptoms and evidence of more than one organ system becoming involved. Treat suspected anaphylaxis on clinical grounds rather than waiting for test results. Following recovery from a systemic reaction, an allergist can correlate the history with fire-ant whole-body-extract skin-prick/intradermal tests and/or Solenopsis-specific serum IgE; an isolated positive sensitization test is not proof that the ant caused a past episode. In the Brazilian 33-patient study, entry required positive skin testing and positive ImmunoCAP i70 specific IgE. That report recommends waiting approximately 3–4 weeks after the event for allergy testing to reduce false negatives and measured basal tryptase as part of its assessment. Tryptase assists assessment of mast-cell disease but did not predict reaction grade in that selected cohort; two patients had values exceeding 11.4 µg/mL and systemic mastocytosis was ruled out. (watanabe2022clinicalandlaboratory pages 1-4, watanabe2022clinicalandlaboratory pages 4-7)

Consider other ant species, bees or wasps, nonvenomous insect bites, nonallergic local infection, cellulitis and alternative causes of sudden hypotension. A typical sterile pustule should not automatically be labeled bacterial infection. ECG, imaging, biopsy, renal testing or creatine kinase are indication-driven, not universal diagnostic requirements; consider renal/muscle testing after heavy stinging or suggestive symptoms. There is no established asymptomatic population, newborn, prenatal, carrier, WGS/WES, gene-panel, chromosomal-microarray, FISH, liquid-biopsy or omics screening test for fire-ant poisoning. For a concerning severe reaction, evaluation for an underlying clonal mast-cell disorder is distinct from diagnosing the sting itself. (chen2026analysisofthe pages 1-2, sukprasert2012characterizationofthe pages 1-3, mcmurray2025fireantvenomanaphylaxis pages 7-9, guillet2022partiinsect pages 4-5)

11. Outcomes and prognosis

Most local effects resolve without permanent injury, but a single systemic reaction can be life-threatening; heavy exposure may cause systemic complications. In the selected mast-cell-disease cohort, 20 fire-ant-anaphylaxis episodes included 11 grade III and nine grade II episodes; almost half initially went unrecognized as anaphylaxis or without epinephrine. These numbers describe severity in a high-risk referral cohort, not the prognosis after an arbitrary sting. In the China mixed-source series three of 8,749 reported cases died; this is a selected-case proportion and cannot be converted to a population case-fatality estimate. No defensible fire-ant-poisoning-specific five- or ten-year survival, life expectancy decrement, standardized disability score, or validated molecular prognostic marker was retrieved. Prognosis depends importantly on exposure burden, prompt treatment of systemic symptoms and host mast-cell disease; ocular injury and secondary infection can complicate recovery. (mcmurray2025fireantvenomanaphylaxis pages 7-9, mcmurray2025fireantvenomanaphylaxis pages 9-10, dioguardi2024therapeuticpotentialof pages 4-6, chen2026analysisofthe pages 6-8)

12. Treatment and real-world implementation

Immediate algorithm: remove the patient from the ants and assess airway, breathing, circulation and generalized symptoms. Suspected anaphylaxis warrants prompt intramuscular epinephrine and emergency services; airway/oxygen, positioning, intravenous fluids and repeated clinician-directed epinephrine as needed are supportive measures. Antihistamines or corticosteroids must not replace epinephrine for anaphylaxis. For uncomplicated local symptoms, cleanse the area and use cold compresses, analgesia and, as appropriate, a topical corticosteroid or antihistamine for itch; monitor for progressive swelling or infection. This combines fire-ant clinical literature with general sting/anaphylaxis management rather than claiming a fire-ant-specific randomized comparison of every supportive measure. Proposed NCIT intervention labels—epinephrine administration, antihistamine therapy, topical corticosteroid therapy, supportive care and allergen immunotherapy—require accession verification. (sukprasert2012characterizationofthe pages 1-3, rodrigo2018immunotherapyinanaphylaxis pages 5-6, rodrigo2018immunotherapyinanaphylaxis pages 4-5, shridhar2022insecttoxicityin pages 4-5, bowles2006fieldguideto pages 48-52)

Future-exposure prevention in allergic patients: Specialist-administered imported-fire-ant whole-body-extract subcutaneous immunotherapy is used following systemic sting allergy with convincing sensitization. This is a real-world service in U.S. TRICARE and was studied in Brazil with an S. invicta/S. richteri extract, escalating to 0.5 mL of 1:100 wt/vol maintenance. In the Brazilian study, 20 patients sustained 35 accidental stings during treatment; three had urticaria only. There were two mild build-up systemic treatment reactions, none during maintenance, and the fire-ant-specific IgG4/IgE ratio rose. The observed field-sting outcomes support effectiveness but are not a placebo-controlled prevention percentage; this cohort was small, selected for severe prior allergy and did not deliberately challenge all participants. Local injection reactions and occasional systemic immunotherapy reactions remain possible. The 2023 review identifies ongoing work on personalized venom-immunotherapy risk assessment and accelerated schedules; a distinct 2024 imported-fire-ant immunotherapy review is indexed but its full text was unavailable for verification here. (watanabe2022clinicalandlaboratory pages 10-13, watanabe2022clinicalandlaboratory pages 1-4, floyd2023updatesandrecent pages 15-17, mcmurray2025fireantvenomanaphylaxis pages 1-2)

Experimental registry finding: ClinicalTrials.gov NCT00435552 describes a completed, double-masked phase-1 evaluation of an Ease-it Spray procedure for sting pain; the retrieved registry record supplies no efficacy result. It is not a trial demonstrating treatment of anaphylaxis. No validated fire-ant-specific antivenom, gene/cell/RNA therapy, surgical correction, genotype-guided medication, or established human therapeutic use of solenopsin was found. Anti-inflammatory/anticancer applications of isolated venom components remain predominantly preclinical and must not be conflated with treating venom poisoning. (NCT00435552 chunk 1, dioguardi2024therapeuticpotentialof pages 6-8)

13. Prevention

Primary: Avoid disturbing mounds, implement surveillance and professionally appropriate colony control in inhabited areas, protect workers and other people with recurrent outdoor exposure, and provide locally relevant education about recognizing ants and nests. Secondary: Identify anaphylaxis immediately, administer epinephrine, and refer survivors of systemic reactions for allergy evaluation; there is no population screening program for asymptomatic people. Tertiary: Provide an individual emergency plan, prescribed autoinjector when indicated, and specialist discussion of whole-body-extract immunotherapy to prevent severe responses to later stings. There is no licensed vaccine, no established prophylactic drug for the general population and no indication for genetic carrier or prenatal screening. (chen2026analysisofthe pages 2-4, mcmurray2025fireantvenomanaphylaxis pages 9-10, rodrigo2018immunotherapyinanaphylaxis pages 5-6, rodrigo2018immunotherapyinanaphylaxis pages 4-5)

14. Other species and naturally occurring disease

Homo sapiens is the subject of the human clinical data; S. invicta, S. richteri and S. geminata are venom-producing exposure species, not human-to-human-transmitted infectious agents. Fire ants can also sting livestock and companion/wild animals: a 2024 review reports that newborn, sick or weakened farm animals may suffer severe attacks, eye injury or disrupted feeding. This establishes veterinary relevance but does not supply validated breed-specific incidence or companion-animal fire-ant case-fatality rates. No zoonotic transmission cycle is involved; cross-species susceptibility reflects exposure to the same venom. NCBI Taxon, VBO and ortholog accessions were not independently checked, and no breed or orthologous causal human gene should be assigned on present evidence. (dioguardi2024therapeuticpotentialof pages 2-4, shridhar2022insecttoxicityin pages 4-5)

15. Model organisms and experimental systems

The most directly relevant induced model is male BALB/c Mus musculus, aged 8–12 weeks in the 2018 original experiment. Hind-footpad sensitization with 10 or 100 µg of fire-ant venom protein and challenge 14 days later reproduced swelling and a type-2 inflammatory component; a separate ovalbumin co-sensitization experiment showed protein-extract adjuvanticity and loss of that effect after heat treatment. This model is useful for venom-protein allergen biology and candidate prevention mechanisms but does not reproduce an unmanipulated human sting, the alkaloid-rich venom dose, a proven human anaphylaxis incidence or decades-long clinical outcomes. A separate S. geminata study generated anti-Sol-gem-2 antibody in mice and tested venom neutralization using crickets; its insect paralysis endpoint is not a human anaphylaxis model. No validated disease-specific knockout, knock-in, humanized model, organoid, single-cell atlas or MGI accession was established. (zamithmiranda2018theallergicresponse pages 6-7, daniel2018theallergicresponse pages 6-9, zamithmiranda2018theallergicresponse pages 7-8, sukprasert2012characterizationofthe pages 1-3)

Terms whose name is worth a second look

The report's name for these is recognisably related to the term's own name without being one of them. A loose paraphrase reads the same way as a citation of the wrong sibling term - and so does a related synonym, which the ontology records precisely because it names something adjacent rather than the same thing - so these are listed rather than judged:

• MONDO:0100341 (2 mentions) - the report calls it "if available"; MONDO calls it fire ant poisoning, and lists "fire ant allergy" among its other names

Every term resolved, and every label the report gave matched.
