Comprehensive Research Report: Glanders (Infectious disease)
Executive summary
Glanders is a highly contagious zoonotic disease caused by the Gram-negative, facultative intracellular bacterium Burkholderia mallei that primarily affects equids (horses, donkeys, mules) and only rarely infects humans, typically via occupational exposure. Clinically, equine disease classically presents as nasal, pulmonary, and cutaneous/lymphatic forms; the cutaneous form is often called farcy. Contemporary control relies on surveillance and early diagnosis (serology plus confirmatory testing) and, in many jurisdictions, euthanasia of infected animals rather than treatment; in humans, aggressive prolonged antibiotic therapy is recommended. Recent (2023–2024) research emphasizes diagnostic challenges from strain genomic variability and demonstrates field-realistic molecular methods (e.g., LAMP) and integrated workflows (culture/PCR/MALDI-TOF/WGS) for confirmation and epidemiologic tracing. (moriya2025detectionofburkholderia pages 1-2, torres2025glandersanancient pages 7-9, charron2023influenceofgenomic pages 1-2, suniga2023glandersdiagnosisin pages 1-2, torres2025glandersanancient pages 9-10)

| Primary hosts / reservoirs | Natural reservoir hosts are mainly equids: horses, donkeys, and mules. Donkeys and mules more often develop acute disease; horses more often have chronic or subclinical infection and may remain occult shedders. Humans are accidental hosts. | (moriya2025detectionofburkholderia pages 1-2, prince2023glandersatreatable pages 1-3, nielsen2022assessmentofthe pages 7-8) |
| Transmission | Spread occurs by direct contact with infected animals/secretions, inoculation through broken skin or harness trauma, inhalation of aerosols/dust, ingestion of contaminated feed/water, and mucosal exposure; human infection is usually occupational and human-to-human transmission is uncommon. | (moriya2025detectionofburkholderia pages 1-2, prince2023glandersatreatable pages 1-3, torres2025glandersanancient pages 7-9) |
| Clinical forms in equids | Main equine presentations: nasal, pulmonary, and cutaneous/farcy forms; acute disease is more common in donkeys/mules and may be rapidly fatal, while horses often show chronic disease with nodules, ulcers, lymphangitis, cough, dyspnea, fever, and weight loss. | (moriya2025detectionofburkholderia pages 1-2, siddique2023burkholderia(malleiand pages 4-7, prince2023glandersatreatable pages 3-5) |
| Clinical forms in humans | Human disease includes cutaneous/localized, pulmonary, chronic/disseminated, and septicemic forms; organ abscesses can involve liver, spleen, and kidneys, and untreated pneumonic disease may be fatal within 10–30 days. | (siddique2023burkholderia(malleiand pages 1-4, siddique2023burkholderia(malleiand pages 4-7, torres2025glandersanancient pages 7-9) |
| Key diagnostics | Standard veterinary diagnosis relies on serology, especially complement fixation test (CFT); confirmatory/adjunct methods include mallein testing, ELISA, western blot, culture, PCR, MALDI-TOF, and WGS. Culture is definitive but often insensitive in field samples. | (tikmehdash2024isolationserologicaland pages 1-2, suniga2023glandersdiagnosisin pages 1-2, torres2025glandersanancient pages 7-9) |
| Recent diagnostic development: antigen variation | Integrative genomics/transcriptomics showed major strain-to-strain variability affecting serodiagnostic antigens: 31–715 gene presence/absence differences (mean 334) and 388 differentially expressed genes between two reference strains, explaining variable serologic performance across lineages. | (charron2023influenceofgenomic pages 1-2) |
| Recent diagnostic development: Iran field screening | In East Azerbaijan, Iran, 350 horses were screened: 11 CFT-positive, of which 6 were confirmed by malleination and 5 were false positives; 1 CFT-negative horse was positive by mallein/ELISA/PCR, for 7 total diagnosed cases. Authors recommend ELISA as a complement to CFT. | (tikmehdash2024isolationserologicaland pages 1-2) |
| Recent diagnostic development: Brazil genomic case confirmation | An asymptomatic Brazilian mare was diagnosed by serology, culture, PCR, MALDI-TOF, and WGS; the isolate belonged to lineage 3, sublineage 2, with a 5.51 Mb genome, 65.8% GC, 5871 genes, and 5583 CDSs. | (suniga2023glandersdiagnosisin pages 1-2, suniga2023glandersdiagnosisin pages 5-7) |
| Recent diagnostic development: LAMP / molecular testing | A dried-format LAMP assay targeting the ITS region detected 10 genomic copies of B. mallei DNA and showed 87.5% agreement with real-time PCR on positive equine swabs and 100% agreement on negatives, offering a simpler field-deployable alternative where PCR resources are limited. | (nakase2025anovelreadytouse pages 1-2) |
| Quantitative epidemiology | Brazil reported 3385 glanders cases (1999–2022), including 715 cases in the most recent 3 years; a Pará study estimated 1.68% prevalence of infected properties. In one Brazilian outbreak series, 37.5% of infected horses were asymptomatic and culture yielded only 8.2% positivity despite PCR confirmation in all tested animals. | (suniga2023glandersdiagnosisin pages 1-2, torres2025glandersanancient pages 5-7) |
| Geographic distribution | Current endemic/re-emerging areas include Brazil, India, Iran, Iraq, Pakistan, Mongolia, parts of the Middle East, Northern Africa, and South/Central America; many formerly affected regions eradicated glanders during the 20th century. | (torres2025glandersanancient pages 1-3, torres2025glandersanancient pages 5-7, nielsen2022assessmentofthe pages 7-8) |
| Pathophysiology / virulence | Important mechanisms include intracellular survival, vacuolar escape, actin-based motility, multinucleated giant-cell formation, serum resistance, capsule/LPS-mediated immune evasion, and virulence functions mediated by T3SS, T6SS-1, VirAG, Hcp1, and BimA. | (burtnick2010burkholderiamalleicluster pages 1-2, burtnick2010burkholderiamalleicluster pages 6-7, burtnick2010burkholderiamalleicluster pages 2-3, siddique2023burkholderia(malleiand pages 1-4) |
| Treatment | For animals, treatment is generally discouraged because eradication is unreliable and zoonotic risk persists; policy usually favors euthanasia. For humans, expert reviews support an intensive IV phase (ceftazidime, imipenem, or meropenem for 10–14 days) followed by an eradication phase (doxycycline or trimethoprim–sulfamethoxazole for 3–6 months). | (torres2025glandersanancient pages 9-10, torres2025glandersanancient pages 7-9, prince2023glandersatreatable pages 5-7) |
| Prevention / control | No licensed vaccine exists for humans or animals. Control depends on surveillance, quarantine, testing of exposed equids, euthanasia of infected animals, carcass/material decontamination, and biosecurity. B. mallei is susceptible to common disinfectants, heat, and UV. | (prince2023glandersatreatable pages 7-10, torres2025glandersanancient pages 9-10, torres2025glandersanancient pages 1-3) |
| Vaccine research / notable antigen | Hcp1 is a leading antigen in diagnostics and vaccine development; experimental platforms include CPS-CRM197 + Hcp1, Hcp1-LPS glycoconjugates, live-attenuated mutants (e.g., ΔtonB, CLH001), and gold nanoparticle vaccines. Protection in animals is promising but partial/variable, and no candidate is licensed. | (badten2024burkholderiapseudomalleicomplex pages 13-14, torres2025glandersanancient pages 9-10, biryukov2022evaluationoftwo pages 1-2, torres2025glandersanancient pages 7-9) |

This tool-assisted literature retrieval did not return authoritative ontology mappings (MONDO ID, MeSH ID, Orphanet, ICD-10/ICD-11 codes) within the retrieved full-text evidence. Consequently, this report cannot cite those identifiers from primary sources in-context and flags them as not available in the current evidence set.
1.4 Evidence sources: individual vs aggregated
Most mechanistic assertions here derive from controlled in vitro or animal-model studies (e.g., macrophage infection models) and expert reviews synthesizing multiple sources, while clinical/epidemiologic data include outbreak/case reports and regional surveillance screening studies. (suniga2023glandersdiagnosisin pages 1-2, torres2025glandersanancient pages 9-10, burtnick2010burkholderiamalleicluster pages 1-2)
2. Etiology
2.1 Primary causal factor
Glanders is caused by Burkholderia mallei, a nonmotile, facultative intracellular Gram-negative bacillus. (burtnick2010burkholderiamalleicluster pages 1-2)
2.2 Transmission and risk factors
Equids (primary reservoir): transmission occurs through direct contact with infected animals/secretions, inhalation of aerosols/dust, ingestion of contaminated feed/water, and inoculation via skin trauma (e.g., harness-related). Asymptomatic carriers can intermittently shed bacteria. (moriya2025detectionofburkholderia pages 1-2, prince2023glandersatreatable pages 3-5)
Humans (accidental host): exposure is usually occupational (animal handlers, veterinarians, laboratory exposure) via broken skin, inhalation, or mucosal contact; human-to-human transmission is described as uncommon/rare. (prince2023glandersatreatable pages 1-3, torres2025glandersanancient pages 7-9)
2.3 Protective factors
No specific host genetic protective variants or validated environmental protective factors were identified in the retrieved evidence corpus.
2.4 Gene–environment interactions
Not applicable in the classic human genetics sense; disease is primarily infectious. However, exposure context (animal husbandry, animal movement/importation, and biosecurity) strongly modifies risk. (prince2023glandersatreatable pages 7-10)
3. Phenotypes (clinical presentation)
3.1 Equids: phenotype catalog
Nasal glanders: pustules/ulcers of nasal mucosa (conchae/septum), sticky/yellow discharge, and regional lymphadenopathy. (moriya2025detectionofburkholderia pages 1-2)
Pulmonary glanders: nodular abscesses in lungs with cough, dyspnea, systemic illness/fever; can progress to pneumonia. (moriya2025detectionofburkholderia pages 1-2)
Cutaneous/lymphatic glanders (farcy): nodular lymphangitis with abscess “buds” (~0.5–2.5 cm) that ulcerate and discharge; enlarged lymphatics. (moriya2025detectionofburkholderia pages 1-2, torres2025glandersanancient pages 7-9)
Course differences by species: donkeys/mules more often show acute disease that can be rapidly fatal; horses often develop chronic disease and may survive for years, including occult carriage. (moriya2025detectionofburkholderia pages 1-2, torres2025glandersanancient pages 3-5)
Asymptomatic infection: an important transmission-relevant state; review evidence reports 37.5% asymptomatic among infected horses in a Brazilian outbreak series. (torres2025glandersanancient pages 5-7)
Suggested HPO terms (examples): - Fever (HP:0001945) - Cough (HP:0012735) - Dyspnea (HP:0002094) - Nasal discharge (HP:0001738) - Nasal ulceration (HP:0032474) / mucosal ulceration (HP:0001074) - Pneumonia (HP:0002090) - Skin ulcer (HP:0001059) - Lymphangitis (HP:0001045) - Lymphadenopathy (HP:0002716)
3.2 Humans: phenotype catalog
Human presentations include cutaneous/local disease (papular lesions that ulcerate), pulmonary disease (can progress to pneumonia/abscess), disseminated/chronic disease, and septicemic disease with internal organ abscesses (e.g., liver, spleen, kidneys). (siddique2023burkholderia(malleiand pages 4-7, torres2025glandersanancient pages 7-9)
Temporal note: incubation is variable; acute cases may occur within 1–14 days and chronic disease can develop over weeks; untreated pneumonic cases may be fatal within 10–30 days. (torres2025glandersanancient pages 7-9)
Suggested HPO terms (examples): - Skin papule (HP:0010011) - Sepsis (HP:0100806) - Liver abscess (HP:0031151) - Splenic abscess (no direct HPO term commonly used; can map to Splenomegaly HP:0001744 and “abscess” phenotypes as appropriate)
3.3 Quality-of-life impact
The retrieved evidence set did not include standardized QoL instrument data (e.g., EQ-5D/SF-36) for glanders.
4. Genetic / molecular information
4.1 Human causal genes
Not applicable: glanders is not a monogenic or polygenic inherited disorder.
4.2 Pathogen genetic features relevant to disease
Whole-genome sequencing of a Brazilian outbreak isolate (BAC 86/19) yielded a genome size ~5.51 Mb and enabled assignment to lineage 3, sublineage 2. (suniga2023glandersdiagnosisin pages 1-2, suniga2023glandersdiagnosisin pages 5-7)
Diagnostic relevance of pathogen genome plasticity: a 2023 integrative genomics/transcriptomics study reported large gene content differences across B. mallei isolates and showed that some serodiagnostic antigens may be lost due to structural variation, complicating serologic diagnosis. (charron2023influenceofgenomic pages 1-2)
Abstract-anchored quote supporting this point: Charron et al. reported “differences in gene content ranging from 31 to 715 genes with an average of 334 gene presence-absence variations,” and that affected genes “included some encoded proteins used as serodiagnostic antigens.” (charron2023influenceofgenomic pages 1-2)
4.3 Epigenetics / chromosomal abnormalities
Not applicable to host genetics in this evidence set; no pathogen epigenetic mechanisms were retrieved.
5. Environmental information
Environmental risk factors in the retrieved evidence are primarily exposure-related (contact with infected equids or contaminated materials) rather than environmental reservoirs (unlike B. pseudomallei). Transmission is supported by inhalation/ingestion/mucosal routes, and control emphasizes disinfection and biosecurity. (moriya2025detectionofburkholderia pages 1-2, prince2023glandersatreatable pages 7-10)
6. Mechanism / pathophysiology
6.1 Causal chain (conceptual)
Exposure → entry (mucosa, inhalation, broken skin) → intracellular infection → dissemination and suppurative lesions → clinical disease.
Mechanistic evidence supports that B. mallei is facultative intracellular, escapes endocytic vacuoles, enters host cytoplasm, and uses actin-based motility for intra-/intercellular spread—processes that link early infection to tissue lesions and dissemination. (burtnick2010burkholderiamalleicluster pages 1-2)
6.2 Virulence factors and pathways
Key virulence determinants include: - Type III secretion system (T3SS): essential for early vacuolar escape and access to intracellular actin pools, supporting actin-based motility and multinucleated giant cell formation. (burtnick2010burkholderiamalleicluster pages 1-2) - Type VI secretion system cluster 1 (T6SS-1): required for virulence; mutants (e.g., tssE) show intracellular growth defects, impaired actin polymerization, and failure to induce multinucleated giant cell formation in macrophages. (burtnick2010burkholderiamalleicluster pages 1-2, burtnick2010burkholderiamalleicluster pages 6-7) - Capsule / LPS-associated immune evasion: capsule described as preventing immune killing; LPS-associated serum resistance is implicated by survival in normal human serum and loss of LPS in serum-sensitive strains. (siddique2023burkholderia(malleiand pages 1-4)
6.3 Immune responses (host)
A 2025 expert review summarizes immunologic observations in naturally infected equids, reporting strong IgG responses and elevated cytokines including IL-1β, MCP-1, IL-17, IL-6, IFN-γ, and TNF-α, and highlights Hcp1 as a prominent antigenic target. (torres2025glandersanancient pages 7-9, torres2025glandersanancient media 41fd19e0)
6.4 Suggested ontology terms for mechanisms
GO Biological Process (examples): - GO:0052040 “negative regulation by symbiont of host immune response” (conceptual fit for immune evasion) - GO:0030260 “bacterial-type flagellum-dependent cell motility” is not appropriate for B. mallei (non-motile); instead consider actin-based intracellular movement processes (host actin polymerization) - GO:0075525 “interleukin-17 production” (host response; aligns with reported IL-17 elevation)
Cell Ontology (CL) cell types (examples): - CL:0000236 macrophage (supported by macrophage infection model data) (burtnick2010burkholderiamalleicluster pages 1-2)
7. Anatomical structures affected
Primary (equids): - Respiratory system: lung (UBERON:0002048), nasal mucosa (UBERON:0001825) - Integumentary/lymphatic: skin (UBERON:0002097), lymphatic vessel (UBERON:0001986), lymph node (UBERON:0000029) (conceptually consistent with lymphangitis/lymphadenopathy) (moriya2025detectionofburkholderia pages 1-2, torres2025glandersanancient pages 7-9)
Humans: pulmonary involvement and systemic organ abscesses (liver, spleen, kidneys). (torres2025glandersanancient pages 7-9)
8. Temporal development
- Onset: acute disease can occur within ~1–14 days post-exposure; chronic disease can develop over weeks (reported up to ~12 weeks). (torres2025glandersanancient pages 7-9)
- Course: equids may be acute (especially donkeys/mules) or chronic (often horses); humans may present with pulmonary, chronic/disseminated, or septicemic forms. (torres2025glandersanancient pages 3-5, torres2025glandersanancient pages 7-9)
9. Inheritance and population
Not applicable (infectious disease). Epidemiology is driven by animal movement, biosecurity, and regional endemicity. (torres2025glandersanancient pages 5-7)
10. Diagnostics
10.1 Current practice and limitations
Diagnosis in animals is “heavily reliant on serological tests” in many settings, and culture can be hazardous and insensitive in field samples. (suniga2023glandersdiagnosisin pages 1-2, tikmehdash2024isolationserologicaland pages 1-2)
10.2 Recent developments (prioritized 2023–2024)
1) Integrated confirmation + genomic epidemiology (Brazil; published Oct 2023) - Multi-pronged diagnosis (serology, culture, PCR, MALDI-TOF, WGS) confirmed B. mallei from an asymptomatic mare in a 2019 outbreak; WGS provided lineage assignment and genomic parameters. (suniga2023glandersdiagnosisin pages 1-2, suniga2023glandersdiagnosisin pages 5-7) - Abstract quote: “The diagnosis was established through a multi-pronged approach encompassing microbiological culture, mass spectrometry, and genome sequencing.” (suniga2023glandersdiagnosisin pages 1-2)
2) Strain variation undermining serodiagnosis (Frontiers in Veterinary Science; Dec 2023) - Gene presence/absence variation and differential expression affect antigens used for serology; this is directly relevant to test robustness across endemic regions. (charron2023influenceofgenomic pages 1-2)
3) Field screening performance and false positives (Iran; May 2024) - Screening of 350 horses: 11 CFT-positive, 6 confirmed by mallein, 5 false positives; 1 CFT-negative but positive on mallein/ELISA/PCR; total 7 diagnosed. (tikmehdash2024isolationserologicaland pages 1-2)
4) Operational molecular diagnostics for resource-limited settings (LAMP; Jan 2025; included due to strong “implementation” relevance) - Dried-format LAMP targeting ITS detected 10 genomic copies and matched real-time PCR with 87.5% agreement for positives and 100% for negatives on equine swabs, supporting deployment where PCR is constrained. (nakase2025anovelreadytouse pages 1-2)
10.3 Differential diagnosis
The retrieved evidence set did not provide a systematic differential diagnosis list; in practice, differentials include other causes of equine respiratory disease, ulcerative nasal disease, and nodular cutaneous/lymphangitic syndromes.
11. Outcome / prognosis
- Humans: severe disease can have high mortality if untreated; untreated pneumonic cases may be fatal within 10–30 days. (moriya2025detectionofburkholderia pages 1-2, torres2025glandersanancient pages 7-9)
- Equids: acute disease can be rapidly fatal; chronic disease may persist for years and can be associated with ongoing shedding. (moriya2025detectionofburkholderia pages 1-2, torres2025glandersanancient pages 3-5)
The evidence set did not provide modern survival curves or population-level case-fatality rates for 2023–2024.
12. Treatment
12.1 Human treatment (expert synthesis)
A 2025 expert review recommends prolonged, aggressive antimicrobial therapy guided by susceptibility testing and experience from melioidosis: an intensive IV phase (10–14 days; ceftazidime, imipenem, or meropenem), followed by a prolonged eradication phase (3–6 months; doxycycline or trimethoprim–sulfamethoxazole). (torres2025glandersanancient pages 9-10)
Suggested MAXO terms (examples): - MAXO:0000746 antibiotic therapy - MAXO:0000058 intravenous drug administration
12.2 Veterinary treatment vs policy
International veterinary policy generally discourages treating infected equids (due to relapse and zoonotic risk) and favors euthanasia plus quarantine/testing for contacts. (torres2025glandersanancient pages 9-10, torres2025glandersanancient pages 7-9)
Nevertheless, a field treatment example cited in a 2023 review describes 23 horses treated over 84 days with oral doxycycline, IV enrofloxacin, and trimethoprim+sulphadiazine, with no relapses reported at end of therapy and negative follow-up indicators (e.g., sentinel horses/foals). (prince2023glandersatreatable pages 5-7)
Suggested MAXO terms (examples): - MAXO:0001084 euthanasia - MAXO:0000746 antibiotic therapy - MAXO:0000915 quarantine
13. Prevention
13.1 Vaccine status
No licensed vaccine exists for humans or animals. (torres2025glandersanancient pages 9-10)
13.2 Public health / veterinary control measures
Control measures include surveillance and testing, strict quarantine of exposed animals, euthanasia of confirmed cases, and thorough disinfection and disposal of contaminated materials. (prince2023glandersatreatable pages 7-10, torres2025glandersanancient pages 7-9)
13.3 Recent vaccine research and expert analysis (including 2023–2024)
A 2024 review of Burkholderia pseudomallei complex vaccines highlights Hcp1 (a T6SS component) as an important immunogenic target in natural infection and summarizes mouse data where intranasal Hcp1 with adjuvants produced substantial protection; glycoconjugate approaches (e.g., Hcp1-LPS constructs on gold nanoparticles) can enhance LPS-specific antibody responses and protection. (badten2024burkholderiapseudomalleicomplex pages 13-14)
Expert limitations highlighted across reviews include: safety concerns for live-attenuated vaccines (reversion/persistence), incomplete protection against chronic disease or high-dose exposures, and dependence on immunization route/adjuvant. (torres2025glandersanancient pages 9-10, biryukov2022evaluationoftwo pages 1-2)
14. Other species / natural disease
Beyond equids and humans, occasional infections have been reported in other mammals (e.g., felids, camels, dogs), while cattle and pigs are described as resistant in an expert review. (torres2025glandersanancient pages 3-5)
Zoonotic acquisition can occur via direct contact and, in carnivores, by consumption of infected meat. (torres2025glandersanancient pages 3-5, prince2023glandersatreatable pages 1-3)
15. Model organisms and experimental systems
- In vitro: murine RAW 264.7 macrophage infection models are used to dissect intracellular survival, secretion-system function, actin polymerization, and cell-to-cell spread. (burtnick2010burkholderiamalleicluster pages 1-2, burtnick2010burkholderiamalleicluster pages 6-7)
- In vivo (preclinical): mouse intranasal/aerosol challenge models are widely used for vaccine down-selection and immune correlate discovery for B. mallei and related B. pseudomallei. (biryukov2022evaluationoftwo pages 1-2)
Recent developments and real-world implementations (2023–2024 focus)
1) Genomics informing surveillance and diagnostics: WGS-confirmed Brazilian outbreak isolate lineage assignment (lineage 3, sublineage 2) illustrates how genomics supports tracing and diagnostic development. (Published Oct 2023; https://doi.org/10.3390/pathogens12101250) (suniga2023glandersdiagnosisin pages 1-2)
2) Evidence-based critique of serodiagnostic robustness: 2023 genomics/transcriptomics study demonstrates that antigen loss/differential expression can undermine serology across B. mallei diversity—an actionable warning for national screening programs. (Published Dec 2023; https://doi.org/10.3389/fvets.2023.1217135) (charron2023influenceofgenomic pages 1-2)
3) Screening data demonstrating CFT false positives in practice: Iran screening study highlights how combining CFT with mallein, ELISA, and PCR improves classification (e.g., 5/11 CFT positives were false positives). (Published May 2024; https://doi.org/10.30466/vrf.2024.2010651.4002) (tikmehdash2024isolationserologicaland pages 1-2)
Key quantitative statistics (recent)
- Brazil reported 3,385 cases (1999–2022) and 715 cases in the last three years, per Ministry of Agriculture and Livestock data accessed 5 Oct 2023. (suniga2023glandersdiagnosisin pages 1-2)
- In a Brazilian outbreak series summarized in a 2025 review: 37.5% asymptomatic among infected horses; PCR positive in all tested animals; culture isolation 8.2% of samples. (torres2025glandersanancient pages 5-7)
- Iran screening (2020–2022 sampling; published 2024): 350 horses screened; 7 diagnosed cases, including a CFT-negative but mallein/ELISA/PCR-positive animal. (tikmehdash2024isolationserologicaland pages 1-2)
Image-based evidence (cropped text from expert review)
The following extracted regions from a 2025 expert review capture compact statements about (i) clinical forms and (ii) immune response markers (Hcp1 and cytokines) and (iii) diagnostic modalities and transmission routes, supporting key summary claims. (torres2025glandersanancient media e5c7470e, torres2025glandersanancient media 41fd19e0, torres2025glandersanancient media 90115587, torres2025glandersanancient media c5f72073)
Gaps and limitations of the current evidence package
- Formal disease identifiers (MONDO, MeSH, ICD-10/ICD-11, Orphanet) were not retrievable from the current document set and therefore cannot be cited here.
- 2023–2024 global incidence/prevalence estimates (beyond Brazil-specific counts accessed in 2023 and regional screening studies) were not available in the retrieved corpus; up-to-date WOAH/WAHIS or national surveillance bulletins would be required for 2023–2024 global statistics.
- Limited information was retrieved on imaging criteria, formal differential diagnosis lists, and standardized quality-of-life outcomes.
