Cat-scratch disease (CSD) — Comprehensive Disease Characteristics Report (Infectious)

Target disease: Cat-scratch disease (CSD)
Causal agent (primary): Bartonella henselae (facultative intracellular Gram-negative bacillus) (puspitasari2025uncoveringthetruth pages 1-2, smith2024catscratchdiseasemimicking pages 3-5)
Last updated: 2026-05-06

Executive summary

Cat-scratch disease is a zoonotic infection most commonly acquired after contact with cats (often kittens), classically presenting as subacute regional lymphadenopathy, sometimes preceded by an inoculation papule/pustule; a clinically important minority develop atypical/disseminated disease (e.g., hepatosplenic microabscesses, osteomyelitis, ocular disease, neurologic syndromes). Key diagnostic modalities in real-world practice are serology (IFA/ELISA), histopathology of lymph node tissue in selected cases, and nucleic-acid detection (PCR or increasingly metagenomic next-generation sequencing [mNGS] for atypical disease). Treatment is often supportive/observational for uncomplicated disease, with azithromycin commonly used to shorten symptom course; complicated ocular/CNS disease is often treated with doxycycline plus rifampin based on expert recommendations and case-based evidence. (amin2022catscratchdisease pages 1-2, amin2022catscratchdisease pages 2-3, sulaiman2023catscratchdisease pages 4-7, rolain2004recommendationsfortreatment pages 6-7)

1. Disease information

1.1 Definition and overview

CSD is an infectious zoonosis “caused by Bartonella henselae infection” and typically presents with “regional lymphadenopathy following a cat scratch or bite.” (smith2024catscratchdiseasemimicking pages 3-5) A recent review similarly defines CSD as a systemic infection due to the intracellular Gram-negative zoonotic bacillus B. henselae. (puspitasari2025uncoveringthetruth pages 1-2)

Direct abstract-supporting quote(s) - “Cat-scratch disease (CSD) is caused by a bacterial infection due to Bartonella henselae…” (Sulaiman et al., 2023-08, Cureus) (sulaiman2023catscratchdisease pages 4-7) - “Cat-scratch disease (CSD) is caused by Bartonella henselae infection.” (Li et al., 2024-04, J Ophthalmic Inflamm Infect) (lai2026clinicalandepidemiological pages 1-2)

1.2 Key identifiers (ontology/clinical)

Not fully retrievable from the currently retrieved full-text corpus. The evidence set did not directly include MONDO, MeSH, or ICD code strings for CSD. (No in-corpus evidence)

What is available from retrieved clinical literature: the disease entity is consistently referenced as “cat-scratch disease,” “cat scratch disease,” and “Bartonella henselae infection,” and is discussed in the context of lymphadenitis/lymphadenopathy differentials. (sulaiman2023catscratchdisease pages 4-7, amin2022catscratchdisease pages 2-3, smith2024catscratchdiseasemimicking pages 3-5)

1.3 Common synonyms / alternative names

• Cat scratch disease / cat-scratch disease (CSD) (sulaiman2023catscratchdisease pages 4-7, smith2024catscratchdiseasemimicking pages 3-5)
• Bartonella henselae lymphadenitis / bartonellosis presenting as lymphadenitis (sulaiman2023catscratchdisease pages 4-7, amin2022catscratchdisease pages 2-3)

1.4 Evidence source types (patient-level vs aggregated)

• Aggregated cohorts: large pediatric clinical cohort (Atlanta, 2010–2018; n=304) providing frequencies and imaging/lab distributions (amin2022catscratchdisease pages 1-2, amin2022catscratchdisease pages 2-3, amin2022catscratchdisease pages 3-4)
• Patient-level case reports/series: multiple 2023–2024 clinical case reports highlighting atypical presentations and diagnostic pitfalls (sulaiman2023catscratchdisease pages 4-7, smith2024catscratchdiseasemimicking pages 3-5)
• Mechanistic reviews/experimental studies: immune evasion and cell biology (Virulence 2024) and neurobartonellosis review (Parasites & Vectors 2024), with supporting in vitro endothelial/erythrocyte tropism and immune-modulation mechanisms (bush2024neurobartonellosesemergingfrom pages 28-29, xi2024sneakytacticsingenious pages 5-6, xi2024sneakytacticsingenious pages 2-4, xi2024sneakytacticsingenious pages 6-7)

2. Etiology

2.1 Disease causal factors

• Infectious cause: Predominantly B. henselae (puspitasari2025uncoveringthetruth pages 1-2, smith2024catscratchdiseasemimicking pages 3-5).
• Occasional related agents: other feline-associated Bartonella spp. (e.g., B. clarridgeiae, B. koehlerae) are discussed as potential causes of similar syndromes in some reviews. (puspitasari2025uncoveringthetruth pages 2-3, puspitasari2025uncoveringthetruth pages 1-2)

2.2 Risk factors

Animal/vector exposure (dominant risk factor class): - High association with cat exposure in pediatric series: 92.4% feline exposure (242/262) in the Atlanta pediatric cohort. (amin2022catscratchdisease pages 1-2) - Review-level risk factors include kittens, fleas, stray/shelter cats, multicat households, outdoor cats, and hot/humid environments. (puspitasari2025uncoveringthetruth pages 5-6)

Host factors: - Immunocompromised status is associated with more severe complications (e.g., bacillary angiomatosis, severe systemic disease); case reports emphasize broadened differential in people living with HIV. (smith2024catscratchdiseasemimicking pages 3-5, puspitasari2025uncoveringthetruth pages 5-6)

Direct abstract-supporting quote(s) - “B. henselae is transmitted from cats to humans through scratching or biting…” (Sulaiman et al., 2023-08, Cureus) (sulaiman2023catscratchdisease pages 4-7)

2.3 Protective factors

No specific genetic protective variants or environmental protective factors were identified in the retrieved evidence. Primary preventive measures are behavioral and veterinary (flea control, avoiding bites/scratches). (puspitasari2025uncoveringthetruth pages 6-7, puspitasari2025uncoveringthetruth pages 5-6)

2.4 Gene–environment interactions

No human host GxE interactions were identified in the retrieved evidence corpus. (No in-corpus evidence)

3. Phenotypes

3.1 Typical phenotype cluster

Core syndrome: inoculation lesion followed by regional lymphadenopathy ± fever. - In a 304-case pediatric cohort, lymphadenopathy occurred in 78.8% (234/297) and fever in 46.4% (141/304). (amin2022catscratchdisease pages 2-3) - Lymph node site distribution in that cohort included cervical 52.0%, axillary 28.3%, and inguinal 13.9% (site denominators vary by documentation). (amin2022catscratchdisease pages 2-3)

Timing: - Papule/pustule may appear 7–12 days after inoculation and lymphadenopathy typically appears 1–3 weeks after inoculation in review literature. (puspitasari2025uncoveringthetruth pages 5-6) - Case-based discussion cites presentation typically 3–14 days after scratch or bite. (smith2024catscratchdiseasemimicking pages 3-5)

3.2 Atypical/disseminated phenotypes (selected)

Atypical presentations are common in tertiary-care cohorts: 20.7% (63/304) lacked lymphadenopathy and were classified as atypical in the Atlanta pediatric cohort. (amin2022catscratchdisease pages 1-2, amin2022catscratchdisease pages 2-3)

Hepatosplenic disease (microabscesses/splenomegaly): among abdominally imaged children (n=55), 38.1% had splenic and/or hepatic microabscesses and 36.4% had splenomegaly. (amin2022catscratchdisease pages 1-2, amin2022catscratchdisease pages 3-4)

Bone involvement: among those with bone MRI (n=20), 35.0% had bone MRI involvement. (amin2022catscratchdisease pages 3-4)

Neuro-ophthalmic / CNS involvement: among those with neuroimaging (n=29), 27.6% had optic neuritis and 17.2% had encephalitis-like findings. (amin2022catscratchdisease pages 3-4)

3.3 Suggested HPO terms and phenotype annotations

A structured phenotype-to-ontology mapping with frequencies and timing is provided in artifact-01.

Table: This table maps major cat-scratch disease phenotypes and complications to suggested HPO and UBERON terms, with quantitative frequencies from the Atlanta pediatric cohort and timing data from recent reviews/case literature. It is useful for ontology-based disease knowledge base population and phenotype annotation.

4. Genetic/molecular information (human)

4.1 Causal genes and variants

CSD is not a Mendelian genetic disease; no causal human gene or pathogenic germline variant set is expected.

4.2 Host genetic susceptibility / modifiers

No reproducible host genetic susceptibility loci, modifier genes, or protective variants were identified in the retrieved evidence corpus. (No in-corpus evidence)

4.3 Pathogen molecular factors (key virulence determinants)

The retrieved evidence supports multiple molecular determinants of B. henselae pathogenicity: - BadA (Bartonella adhesin A): implicated in host cell adhesion and biofilm formation; linked to VEGF induction and angiogenic responses. (xi2024sneakytacticsingenious pages 5-6, xi2024sneakytacticsingenious pages 2-4, gadila2025comparisonoftranscriptomic pages 1-2) - Type IV secretion systems: VirB/D4 and Trw systems contribute to endothelial and erythrocyte interactions (erythrocyte binding/invasion and persistence). (xi2024sneakytacticsingenious pages 5-6, xi2024sneakytacticsingenious pages 6-7) - BafA (Bartonella angiogenic factor A): described as binding VEGFR2 and acting as a VEGF mimic in mechanistic discussion. (xi2024sneakytacticsingenious pages 6-7)

5. Environmental information

5.1 Environmental factors

The dominant environmental contributors are zoonotic exposures (cats and cat-associated fleas), rather than classic toxin or pollution exposures. (puspitasari2025uncoveringthetruth pages 2-3, puspitasari2025uncoveringthetruth pages 5-6)

5.2 Lifestyle factors

No specific lifestyle factors (diet, smoking, alcohol) were identified in the retrieved evidence as independent risk modifiers. (No in-corpus evidence)

5.3 Infectious agent

• Bartonella henselae (primary). (puspitasari2025uncoveringthetruth pages 1-2, smith2024catscratchdiseasemimicking pages 3-5)

6. Mechanism / pathophysiology

6.1 Causal chain (high-level)

1) Inoculation via scratch/bite/lick introduces B. henselae into skin and local tissues. (sulaiman2023catscratchdisease pages 4-7, puspitasari2025uncoveringthetruth pages 5-6)
2) Local immune activation with regional lymph node involvement; inflammatory cytokines including IL-2/IL-6/IL-10 have been reported in CSD patients in mechanistic review. (xi2024sneakytacticsingenious pages 2-4)
3) Cell tropism and persistence: bacteria invade endothelial cells and form Bartonella-containing vacuoles that resist acidification and lysosomal fusion, enabling intracellular survival; erythrocyte invasion provides an “immunological cloak”/sanctuary promoting persistent bacteremia. (xi2024sneakytacticsingenious pages 5-6, xi2024sneakytacticsingenious pages 6-7)
4) Dissemination in some hosts results in hepatosplenic, bone, ocular, and neurologic disease; neurobartonellosis review highlights multiple potential reservoirs and cell types enabling CNS effects. (bush2024neurobartonellosesemergingfrom pages 28-29)

6.2 Cellular and immune processes (with ontology suggestions)

Key processes (GO Biological Process suggestions): - Granulomatous inflammation (GO:0006954 inflammatory response; granuloma formation—closest mapping often via inflammatory response terms) supported by lymph node histopathology patterns (necrotizing granulomatous inflammation). (amin2022catscratchdisease pages 2-3, sulaiman2023catscratchdisease pages 4-7) - Angiogenesis / vasoproliferation (GO:0001525 angiogenesis) via VEGF induction and VEGF-mimic factors (BadA-associated VEGF induction; BafA–VEGFR2 mimicry described). (xi2024sneakytacticsingenious pages 5-6, xi2024sneakytacticsingenious pages 6-7) - Intracellular survival / evasion of lysosomal fusion (GO:0045087 innate immune response; GO:0045321 leukocyte activation; and processes related to endosome/lysosome trafficking), via BCVs resisting lysosomal fusion/acidification. (xi2024sneakytacticsingenious pages 5-6, xi2024sneakytacticsingenious pages 6-7) - Immune regulation via IL-10 / STAT3 axis (GO:0006955 immune response; GO:0001817 regulation of cytokine production), enabling anti-inflammatory persistence. (bush2024neurobartonellosesemergingfrom pages 28-29, xi2024sneakytacticsingenious pages 2-4)

Key cell types (Cell Ontology [CL] suggestions): - Vascular endothelial cell (CL:0000115), including HUVEC experimental systems used to assay virulence/angiogenesis. (kondo2025differentialvasoproliferativetraits pages 1-2, xi2024sneakytacticsingenious pages 5-6) - Erythrocyte (CL:0000232) for intraerythrocytic persistence. (xi2024sneakytacticsingenious pages 6-7) - Macrophage (CL:0000235), including possible “Trojan-horse” dissemination concept to brain. (bush2024neurobartonellosesemergingfrom pages 28-29) - Microglial cell (CL:0000129) and pericyte (CL:0000669) noted as in vitro-infected cell types in neurobartonellosis review. (bush2024neurobartonellosesemergingfrom pages 28-29) - CD34-positive hematopoietic progenitor cell (CL:0000055) as a potential reservoir niche. (xi2024sneakytacticsingenious pages 6-7)

Anatomy (UBERON suggestions): - Skin (UBERON:0001003) inoculation site; lymph node (UBERON:0000029) primary clinical involvement. (puspitasari2025uncoveringthetruth pages 5-6, amin2022catscratchdisease pages 2-3) - Spleen (UBERON:0002106) and liver (UBERON:0002107) in hepatosplenic CSD. (amin2022catscratchdisease pages 3-4) - Retina (UBERON:0000966) and optic nerve (UBERON:0001004) in ocular disease. (amin2022catscratchdisease pages 3-4) - Brain (UBERON:0000955) for CNS manifestations (encephalitis-like findings). (amin2022catscratchdisease pages 3-4)

6.3 Recent mechanistic developments (2023–2024 priority)

• Immune evasion/persistence synthesis (2024, Virulence): review describes endothelial invasion with vacuoles resisting lysosomal fusion, erythrocyte “sanctuaries,” BadA-associated VEGF induction and angiogenic modulation, and immune modulation including IL-10 pathways and biofilm-mediated protection. (xi2024sneakytacticsingenious pages 5-6, xi2024sneakytacticsingenious pages 2-4, xi2024sneakytacticsingenious pages 6-7)
• Neurobartonellosis conceptual expansion (2024, Parasites & Vectors): review emphasizes intracellular niches (endothelial cells, stromal cells, pericytes, microglia) and macrophage-mediated CNS access (“Trojan-horse”), plus VEGF-driven vascular remodeling/permeability as a plausible contributor to neurologic dysfunction. (bush2024neurobartonellosesemergingfrom pages 28-29)

7. Anatomical structures affected

Primary: lymph nodes (regional), skin at inoculation. (puspitasari2025uncoveringthetruth pages 5-6, amin2022catscratchdisease pages 2-3)

Secondary (disseminated/atypical): - Hepatosplenic: liver and spleen microabscesses/splenomegaly (amin2022catscratchdisease pages 3-4) - Musculoskeletal: bone involvement/osteomyelitis-like findings (amin2022catscratchdisease pages 3-4) - Ocular/neuro-ophthalmic: optic nerve involvement/optic neuritis, neuroretinitis (amin2022catscratchdisease pages 3-4, lai2026clinicalandepidemiological pages 1-2) - CNS: encephalitis-like findings (amin2022catscratchdisease pages 3-4)

8. Temporal development

Onset pattern: typically subacute. - In review literature, inoculation lesion precedes regional lymphadenopathy by ~1–3 weeks; papule/pustule at ~7–12 days post-inoculation. (puspitasari2025uncoveringthetruth pages 5-6)

Duration/course: - Disease is often self-limited; expert recommendations note regional lymphadenopathy commonly lasts 2–3 months. (rolain2004recommendationsfortreatment pages 6-7) - Another clinical summary reports typical CSD is self-limited resolving in 2–6 months. (nguyen2024threemonthhistoryof pages 4-6)

9. Inheritance and population

9.1 Epidemiology

Structured quantitative epidemiology statistics are provided in artifact-00.

Table: This table compiles explicit quantitative epidemiology and clinical statistics for cat-scratch disease from the retrieved literature, with emphasis on U.S. burden estimates and the Atlanta pediatric cohort. It is useful as a structured evidence summary for knowledge-base population and citation tracking.

Key recent/usable estimates from retrieved sources include: - US outpatient diagnosis rates 4.5–9.3 per 100,000 and hospitalization 0.19–0.86 per 100,000 (sulaiman2023catscratchdisease pages 4-7). - Pediatric incidence peak cited at 9.4 per 100,000 among US children age 5–9 years (amin2022catscratchdisease pages 1-2). - Seasonality in a large Atlanta pediatric cohort showed peaks in August–November, with September highest (15.5% of diagnoses). (amin2022catscratchdisease pages 2-3, amin2022catscratchdisease media 65029abb)

9.2 Demographics

• In Atlanta pediatric cohort: median age 8.1 years (IQR 5.4–12.1) and 51.3% female. (amin2022catscratchdisease pages 1-2)

9.3 Genetic inheritance

Not applicable (infectious disease). No inherited transmission pattern.

10. Diagnostics

A structured diagnostics summary including cutoffs and performance notes is provided in artifact-02.

Table: This table summarizes the main diagnostic modalities and treatment approaches for cat-scratch disease, including practical cutoff values, performance notes, commonly used regimens, and ontology-ready MAXO action suggestions. It is useful for translating the literature into a structured disease knowledge-base entry.

10.1 Common diagnostic approaches (current practice)

• Serology (IFA/ELISA): commonly first-line; in the Atlanta cohort, IFA positivity thresholds were IgM >1:20 and IgG ≥1:128. (amin2022catscratchdisease pages 1-2, puspitasari2025uncoveringthetruth pages 6-7)
• Histopathology: used in selected cases (e.g., malignancy work-up or persistent/suppurative nodes) with necrotizing granulomatous inflammation patterns. (amin2022catscratchdisease pages 2-3, sulaiman2023catscratchdisease pages 4-7)
• PCR: useful but imperfect sensitivity; reported lymph node PCR sensitivity 30–60% in a case-based review, improving with multimodal evidence. (sulaiman2023catscratchdisease pages 4-7)
• mNGS: increasingly used for atypical disease or unusual specimens (e.g., aqueous humor); an ocular case reported 521 B. henselae reads in aqueous humor (lai2026clinicalandepidemiological pages 1-2), and a pediatric series detected B. henselae in all 20 mNGS-tested specimens (lai2026clinicalandepidemiological pages 3-4).

10.2 Differential diagnosis (high-yield)

CSD can mimic neoplastic causes of lymphadenopathy (e.g., lymphoma) and granulomatous infections (e.g., tuberculosis), motivating biopsy and/or molecular testing in atypical presentations. (smith2024catscratchdiseasemimicking pages 3-5, lai2026clinicalandepidemiological pages 3-4)

11. Outcome / prognosis

• Typical/uncomplicated disease: generally favorable and self-limited over weeks to months, often without antibiotics. (sulaiman2023catscratchdisease pages 4-7, rolain2004recommendationsfortreatment pages 6-7, puspitasari2025uncoveringthetruth pages 5-6)
• Atypical/disseminated disease: can involve hepatosplenic, ocular, bone, or neurologic manifestations; outcomes are usually good with appropriate recognition and management in contemporary cohorts/case series, but can be severe in immunocompromised hosts. (amin2022catscratchdisease pages 3-4, smith2024catscratchdiseasemimicking pages 3-5)
• Real-world pediatric cohort finding: in the Atlanta cohort, ~20% received no antibiotics and retrospective analyses found no significant outcome differences between treated and untreated groups (interpretation limited by confounding by indication). (amin2022catscratchdisease pages 4-6)

12. Treatment

Treatment and MAXO action suggestions are summarized in artifact-02.

12.1 Uncomplicated lymphadenitis

• Many cases are self-limited (rolain2004recommendationsfortreatment pages 6-7, puspitasari2025uncoveringthetruth pages 5-6).
• A commonly cited regimen for severe lymphadenopathy is azithromycin 10 mg/kg day 1 then 5 mg/kg days 2–5. (puspitasari2025uncoveringthetruth pages 6-7)

12.2 Complicated disease (ocular/CNS; disseminated)

• For ocular or CNS involvement, expert recommendations include doxycycline 100 mg twice daily + rifampin 300 mg twice daily. (rolain2004recommendationsfortreatment pages 6-7)
• Contemporary practice patterns in an mNGS-confirmed pediatric series included combinations such as azithromycin + rifampicin and doxycycline + rifampicin, with all hospitalized children improving and being discharged. (lai2026clinicalandepidemiological pages 3-4)

12.3 Evidence quality note (expert analysis)

The treatment literature remains heterogeneous; classic expert recommendations note limited antibiotic benefit in typical lymphadenitis, while complicated disease is often treated with combination regimens based on pathophysiology (intracellular niches) and case-series experience rather than high-quality randomized trials. (rolain2004recommendationsfortreatment pages 6-7, nguyen2024threemonthhistoryof pages 4-6)

13. Prevention

Primary prevention is focused on interrupting zoonotic transmission: - Flea control on cats and avoiding scratches/bites/licks that break skin are consistently recommended. (puspitasari2025uncoveringthetruth pages 6-7, puspitasari2025uncoveringthetruth pages 5-6, nemade2023catscratchdisease pages 1-3) - Human-to-human transmission has not been documented, supporting zoonotic prevention emphasis. (puspitasari2025uncoveringthetruth pages 2-3)

14. Other species / natural disease (One Health)

14.1 Reservoirs and vectors

• Primary reservoir: domestic cats (especially kittens); cats frequently have asymptomatic bacteremia and can remain bacteremic for prolonged periods (weeks to years). (puspitasari2025uncoveringthetruth pages 2-3, nemade2023catscratchdisease pages 3-6)
• Vector maintaining infection among cats: cat flea Ctenocephalides felis. (puspitasari2025uncoveringthetruth pages 2-3, puspitasari2025uncoveringthetruth pages 5-6)

14.2 Zoonotic transmission routes

• Infection is typically acquired via scratches/bites, including contamination with flea feces and/or cat oral flora (bites/licks that breach skin). (nemade2023catscratchdisease pages 3-6, puspitasari2025uncoveringthetruth pages 5-6)
• Human-to-human transmission is not documented. (puspitasari2025uncoveringthetruth pages 2-3)

14.3 Other species relevance

Reviews note broader Bartonella host ranges and occasional discussion of dogs/other mammals/ticks in the ecology of bartonellosis, though CSD in humans remains most strongly associated with feline exposure. (puspitasari2025uncoveringthetruth pages 2-3, puspitasari2025uncoveringthetruth pages 5-6)

15. Model organisms and experimental systems

15.1 In vitro models

• Human umbilical vein endothelial cells (HUVECs) are used to quantify strain-level differences in vasoproliferative traits and to study endothelial interactions relevant to angiogenic pathology. (kondo2025differentialvasoproliferativetraits pages 1-2)

15.2 Natural-host / in vivo models

• Experimental inoculation studies in cats (natural reservoir) are discussed in review literature, typically showing asymptomatic or mild/transient signs, supporting cats as a reservoir model relevant to One Health. (puspitasari2025uncoveringthetruth pages 5-6)

Visual evidence from a key cohort paper

The Atlanta pediatric cohort paper includes figures/tables summarizing month-by-month seasonality and radiologic findings; these were retrieved as images and support the quantitative seasonality and multi-organ involvement described above. (amin2022catscratchdisease media 65029abb, amin2022catscratchdisease media 4aebcb1f, amin2022catscratchdisease media 79399fa7, amin2022catscratchdisease media 3ce93ca4)

Recent developments (2023–2024 emphasis)

1) Expanded molecular diagnostics for atypical disease: mNGS has been used to confirm ocular bartonellosis from intraocular fluid (aqueous humor), enabling diagnosis even when classic history or serology is limited. (Li et al., 2024-04; https://doi.org/10.1186/s12348-024-00387-0) (lai2026clinicalandepidemiological pages 1-2)
2) Mechanistic consolidation of immune-evasion/persistence: 2024 mechanistic review emphasizes intracellular vacuoles resisting lysosomal fusion, erythrocyte sanctuaries, immune modulation (IL-10), and biofilm-mediated persistence—concepts that explain culture-negativity and chronic/recurrent manifestations. (Xi et al., 2024-03; https://doi.org/10.1080/21505594.2024.2322961) (xi2024sneakytacticsingenious pages 5-6, xi2024sneakytacticsingenious pages 2-4, xi2024sneakytacticsingenious pages 6-7)
3) Broadened neurologic phenotype framing (“neurobartonelloses”): 2024 review highlights the breadth of reported neurologic syndromes and plausible vascular/immune mechanisms (VEGF-driven remodeling, intracellular niches, macrophage shuttling). (Bush et al., 2024-10; https://doi.org/10.1186/s13071-024-06491-3) (bush2024neurobartonellosesemergingfrom pages 28-29)

Limitations of this report (evidence gaps in retrieved corpus)

• Ontology identifiers (MONDO/MeSH/ICD-10/ICD-11/Orphanet/OMIM) were not directly available in the retrieved full-text set, so they are not populated here.
• Human genetic susceptibility evidence (GWAS/ClinVar/ClinGen) was not identified in the retrieved set.
• Some frequently cited classic RCTs (e.g., 1998 azithromycin trial) were not obtainable as full text in this run; key regimen details were nonetheless captured via other authoritative sources in-corpus. (rolain2004recommendationsfortreatment pages 6-7, puspitasari2025uncoveringthetruth pages 6-7)
