Although antibodies to Bartonella henselae have been described in all neotropical felid species, DNA has been detected in only one species, Leopardus wiedii. The aim of this study was to determine whether DNA of Bartonella spp. could be detected in blood of other captive neotropical felids and evaluate risk factors and hematological findings associated with infection. Blood samples were collected from 57 small felids, including 1 Leopardus geoffroyi, 17 L. wiedii, 22 Leopardus tigrinus, 14 Leopardus pardalis, and 3 Puma yagouaroundi; 10 blood samples from Panthera onca were retrieved from blood banks. Complete blood counts were performed on blood samples from small felids, while all samples were evaluated by PCR. DNA extraction was confirmed by amplification of the cat GAPDH gene. Bartonella spp. were assessed by amplifying a fragment of their 16S-23S rRNA intergenic spacer region; PCR products were purified and sequenced. For the small neotropical felids, risk factors [origin (wild-caught or zoo-born), gender, felid species, and flea exposure] were evaluated using exact multiple logistic regression. Hematological findings (anemia, polycythemia/hyperproteinemia, leukocytosis and leukopenia) were tested for association with infection using Fisher's exact test. The 635bp product amplified from 10 samples (10/67=14.92%) was identified as B. henselae by sequencing. Small neotropical felid males were more likely to be positive than females (95% CI=0.00-0.451, p=0.0028), however other analyzed variables were not considered risk factors (p>0.05). Hematological abnormalities were not associated with infection (p>0.05). This is the first report documenting B. henselae detection by PCR in several species of neotropical felids.
