“…This study confirms the previous reports of Bartonella antibodies in Californian pumas and bobcats [24] and Florida panthers [22], and extends the known distribution of this infection throughout most of the geographical range of these wild felids. It is the first report of Bartonella antibodies in free-ranging and captive pumas and bobcats from various parts of North, Central and South America.…”

“…Continuing surveillance of Bartonella antibodies in Florida panthers will be necessary to determine if infection is spreading among these animals. The Bartonella antibody prevalence for California bobcats in our study was somehow lower (29.2%, 14/48) than previously reported (53%, 33/62) [24]. This difference may be attributable to the geographical origin of our respective bobcat populations.…”

“…This distribution superposes well with the reported distribution of Bartonella infection in domestic cats [12], and also fits with the known distribution of the main vectors of Bartonella spp., especially fleas, as reported for domestic cats [6,12,13]. In free-ranging pumas from California, we found a seroprevalence of 28.5%, which is close to the 35% previously reported for 74 free-ranging California pumas [24]. We found a higher Bartonella antibody prevalence in pumas from Texas (40%, 16/40) than the prevalence of 28% (2/7) reported by Rotstein et al [22].…”

“…A sero-epidemiological study of B. henselae infection in free-ranging and captive wild felids was conducted a few years ago in California [24]. Fifty-three percent of 62 free-ranging bobcats (Lynx rufus) and 35% of 74 free-ranging pumas (Felis concolor) trapped in California were seropositive for B. henselae, and 30% of 114 captive wild felids (genera Acinonyx, Panthera and Felis) had B. henselae antibodies.…”

-Bartonella henselae is the main agent of cat scratch disease in humans and domestic cats are the main reservoir of this bacterium. We conducted a serosurvey to investigate the role of American wild felids as a potential reservoir of Bartonella species. A total of 479 samples (439 serum samples and 40 Nobuto strips) collected between 1984 and 1999 from pumas (Felis concolor) and 91 samples (58 serum samples and 33 Nobuto strips) collected from bobcats (Lynx rufus) in North America, Central America and South America were screened for B. henselae antibodies. The overall prevalence of B. henselae antibodies was respectively 19.4% in pumas and 23.1% in bobcats, with regional variations. In the USA, pumas from the southwestern states were more likely to be seropositive for B. henselae (prevalence ratio (PR) = 2.82, 95% confidence interval (CI) = 1.55, 5.11) than pumas from the Northwest and Mountain states. Similarly, adults were more likely to be B. henselae seropositive than juveniles and kittens (PR = 1.77, 95% CI = 1.07, 2.93). Adult pumas were more likely to have higher B. henselae antibody titers than juveniles and kittens (p = 0.026). B. henselae antibody prevalence was 22.4% (19/85) in bobcats from the USA and 33.3% (2/6) in the Mexican bobcats. In the USA, antibody prevalence varied depending on the geographical origin of the bobcats. In California, the highest prevalence was in bobcats from the coastal range (37.5%). These results suggest a potential role of wild felids in the epidemiological cycle of Bartonella henselae or closely related Bartonella species.
