Vm. Dickinson et al., Nasal and cloacal bacteria in free-ranging desert tortoises from the western United States, J WILDL DIS, 37(2), 2001, pp. 252-257
Aerobic bacteria were collected from three free-ranging dc sc rt tortoise (
Gopherus agassizii) populations in the eastern Mojave Desert (Arizona, Utah
: USA) from 1989 to 1993, and from two free-ranging populations in the cent
ral Sonoran Desert (Arizona, USA) from 1990 to 1994. Six species of nasal b
acteria and 18 species of cloacal bacteria were identified. At least one po
tential pathogen was found in the nasal cavity (Pasteurella testudinis), an
d at least two potential pathogens in the cloaca (Pseudomonas spp., Salmone
lla spp.).
