The aim of the present work was to determine by blood culture the
prevalence of blood infection with Bartonella species in a well- defined,
European, urban stray cat population. Therefore, 94 stray cats were trapped
from 10 cat colonies. Blood samples of these cats were cultured on both
blood agar and liquid medium in order to raise the likelihood of bacterial
detection. Fifty blood samples (53%) gave a positive culture result for
Bartonella species. Isolate identification was performed by sequencing the
first 430 bases of the 16S ribosomal DNA. Three types of sequences were
thus obtained. The first type (17 isolates; 34%) was identical to that of
B. henselae Houston-1 and the corresponding strains were referred as B.
henselae type I. The second sequence type (18 isolates; 36%) was identical
to that initially described as "BA-TF," and the corresponding strains were
referred to as B. henselae type II. The third sequence type (15 isolates;
30%) was identical to that of the Bartonella clarridgeiae type strain (ATCC
51734). Our study points out the major role of stray cats as a reservoir of
Bartonella spp. which can be transmitted to pet cats and, consequently, to
humans. The study also highlights the high prevalence of B. clarridgeiae
(16%) in the blood of stray cats.
