Prevalence of selected pathogens in western pond turtles and sympatric introduced red-eared sliders in California, USA.

摘要: Pathogen introduction by invasive species has been speculated to be a cause of declining western pond turtle Emys marmorata populations in California, USA. This study deter- mined the prevalence Ranavirus spp., Herpesvirus Mycoplasma spp. (via polymerase chain reaction blood and nasal flush contents), Salmonella infection fecal culture) native E. red-eared sliders Trachemys scripta elegans compared sympatric with T. mar- morata that were not sampling 145 33 ele- gans at 10 sites throughout California. detected both species: was 7.8% northern, 9.8% central, 23.3% southern California regions. In elegans, northern region but 4.5 14.3% central regions, respectively. All turtles tested negative for Enteric bacteria isolated from feces. did have increased risk infection.
