Serological and Molecular Evidence of Bartonella henselae in Stray Cats from Southern Italy
2021
Bartonella henselae is a slow growing and facultative intracellular pathogen mainly transmitted by arthropod vectors adapted to domestic and wild mammalian reservoir hosts. Since cats are the major source of the B. henselae infection, this study aimed to evaluate the seroprevalence and the DNA presence in randomly sampled stray cats. Blood samples of 429 cats were collected from shelter of Palermo (Southern Italy) and sera and whole blood were analyzed for the presence of antibodies against B. henselae by indirect immunofluorescence assay (IFA) and by real-time polymerase chain reaction (PCR), respectively. Two hundred and three sera (47.3%) were positive to IFA and 148 blood samples (34.5%…
PREVALENCE OF ANTIBODIES ANTI-BARTONELLA HENSELAEIN WESTERN SICILY: CHILDREN, BLOOD DONORS, AND CATS
2011
To evaluate seroprevalence of B. henselae infection both in Sicilian children and healthy blood donors. Furthermore, circulation of Bartonella in the natural reservoir was also studied. Two hundred forty-three children, living in Sicily (Palermo), affected by various diseases, without clinical features suggesting B. henselae infection, together with 122 healthy blood donors were serologically investigated for IgG and IgM antibodies by indirect fluorescent antibody test (IFAT). One hundred twenty stray and 62 pet cats were also analyzed only for IgG. Among children 25.1% had IgG antibodies to B. henselae; 18.5% showed a titer 1:64, 2.4% 1:128, 2.4% 1:256, 0.8% 1:512, 0.4% 1:1024, and 0.4% 1:…
Atypical bartonella henselae neuroretinitis in an immunocompetent patient
2014
We report a case of a 57-year-old immunocompetent male, admitted to our Department due to the loss of visual acuity to the right eye, occurred during the two weeks before the hospitalization, and hyperglycaemia. Our patient suffered from metabolic syndrome, characterized by visceral obesity, impaired glucose tolerance, arterial hypertension, complicated by proteinuria, and moderate grade hypertensive retinopathy. Surprisingly, and despite its many comorbidities, the final diagnosis was neuroretinitis by Bartonella henselae, without any other symptoms/signs of cat-scratch disease. The patient denied any kind of contact with cats. He was cured by specific antibiotic therapy, restoring status …
