Sepúlveda-García P, Alabi A, Álvarez K, Rojas L, Mella A, Gonçalves LR, André MR, Machado RZ, Müller A, Monti G. Bartonella spp. in households with cats: Risk factors for infection in cats and human exposure. One Health 2023; 16:100545. [PMID: 37363214 PMCID: PMC10288095 DOI: 10.1016/j.onehlt.2023.100545] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 04/14/2023] [Accepted: 04/17/2023] [Indexed: 06/28/2023] Open
Abstract
The aim of this study was to estimate the occurrence of Bartonella spp. per household in cats and the risk factors for Bartonella spp. positivity in cats and their owners from Valdivia, Chile. A total of 464 cats (distributed within 324 households) and 326 humans (control group [n = 112] and cat owner [n = 214]) distributed in 262 households were sampled. From the cat owners (n = 214), 128 humans were in households where the cat was also sampled, totaling 84 households with dual sampling. Real-time PCR (qPCR) was used for Bartonella spp. detection in blood from cats and humans, and immunofluorescent immunoassay (IFA) anti-Bartonella henselae was performed in human serum samples. Out of the total of 324 households, 20.43% presented at least one Bartonella positive cat. From the households with dual sampling, 29.7% (25/84) presented at least one qPCR-Bartonella spp. positive cat. However, Bartonella DNA was not amplified in humans, and in 7.3% (6/82) of the households was found at least one of the cat's owners exposed to B. henselae. Cats younger than one year (Odds Ratio (OR) = 5.3), non-neutered (OR 3.46), sampled at home (OR 5.82), and with improper application of tick/flea control products (OR 3.13) showed a higher risk for Bartonella spp. presence. Humans with occupational exposure involving animal contact, were more likely to exhibit B. henselae seropositivity (OR 7.5). Bartonella spp. was present in the cats a moderate number of households, but Bartonella DNA was not detected in owners' blood, inferring that there is a low risk of recent human infection in the studied population.

Abstract
UNLABELLED Cat scratch disease (CSD) is caused by Bartonella henselae, with unknown prevalence and incidence in the Chilean paediatric population. Regional lymphadenopathy is the most common presentation, while atypical forms constitute a diagnostic challenge. OBJECTIVE To report a case of CSD with osteomyelitis and present guidelines regarding treatment. CLINICAL CASE An eight year-old patient, with prolonged febrile illness, back pain and neck stiffness. Laboratory studies highlight positive IgG for Bartonella henselae. The abdominal ultrasound showed splenic micro-abscesses, and the MRI showing vertebral lesions suggestive of osteomyelitis. DISCUSSION The diagnosis of atypical forms requires a high rate of suspicion, as in this case, in which the patient manifested the musculoskeletal symptoms simultaneously with the febrile syndrome, which led us to study possible complications of the disease. Current knowledge of the treatment of atypical or complicated CSD is derived from the observation of case studies, rather than randomized trials. It is suggested that antibiotic therapy is analysed individually, with the help of a specialist. CONCLUSION The importance of high clinical suspicion are emphasised and discussed, as well presenting some treatment options based on the evidence from the current literature.
