| Summary: | American bison (Bison bison) is listed as near-threatened and in danger of extinction in
Mexico. Recent studies have demonstrated the presence of several emerging pathogens at the Janos
Biosphere Reserve (JBR), inhabited by one wild herd of American bison. Blood samples were collected
from 26 American bison in the JBR. We tested for the presence of Anaplasma marginale, Babesia bigemina,
B. bovis, Borrelia burgdorferi sensu lato, and Rickettsia rickettsii DNA using nested and semi-nested
PCR protocols performing duplicates in two different laboratories. Results showed three animals
(11.5%) positive for B. burgdorferi s. l., three more (11.5%) for Rickettsia rickettsii, and four (19.2%) for
B. bovis. Two individuals were co-infected with B. burgdorferi s. l. and B. bovis. We found no animals
positive for A. marginale and B. bigemina. This is the first report in America of R. rickettsii in American
bison. American bison has been described as an important reservoir for pathogens of zoonotic and
veterinary importance; thus, the presence of tick-borne pathogen DNA in the JBR American bison
indicates the importance of continuous wildlife health surveys. |
