Hypothesis
What is the geographic distribution of Bartonella vinsonii subsp. berkhoffii infection in California coyotes?
Conclusion
The study found that the prevalence of Bartonella vinsonii subsp. berkhoffii antibodies in coyotes varied significantly across California, with higher rates in coastal areas.
Supporting Evidence
- The overall prevalence of B. vinsonii subsp. berkhoffii-seropositive coyotes was 35%.
- Seropositive coyotes were more likely to be from coastal than inland counties.
- Antibody prevalence was higher in adult coyotes than in young coyotes.
- Summer had the highest prevalence of Bartonella-seropositive coyotes.
Takeaway
This study looked at how many coyotes in California have a certain germ that can make them sick, and it found that more coyotes near the coast are sick than those further inland.
Methodology
Coyote blood samples were collected from 34 counties in California and tested for antibodies against B. vinsonii subsp. berkhoffii using enzyme-linked immunosorbent assay.
Limitations
Limited data on the actual distribution of various arthropods throughout California.
Participant Demographics
Coyotes from various regions in California, with no gender difference in seropositivity detected.
