ABSTRACT

Ecologies of zoonotic vector-borne diseases may shift with climate and land use change. As many urban-adapted mammals can host ectoparasites and pathogens of human and animal health concern, our goal was to compare patterns of arthropod-borne disease among medium-sized mammals across gradients of rural to urban landscapes in multiple regions of California. DNA of Anaplasma phagocytophilum was found in 1-5% of raccoons, coyotes, and San Joaquin kit foxes; Borrelia burgdorferi in one coyote, rickettsiae in two desert kit foxes, and Yersinia pestis in two coyotes. There was serological evidence of rickettsiae in 14-37% of coyotes, Virginia opossums, and foxes; and A. phagocytophilum in 6-40% of coyotes, raccoons, Virginia opossums, and foxes. Of six flea species, one Ctenocephalides felis from a raccoon was positive for Y. pestis, and Ct. felis and Pulex simulans fleas tested positive for Rickettsia felis and R. senegalensis. A Dermacentor similis tick off a San Joaquin kit fox was PCR-positive for A. phagocytophilum. There were three statistically significant risk factors: risk of A. phagocytophilum PCR-positivity was threefold greater in fall vs the other three seasons; hosts adjacent to urban areas had sevenfold increased A. phagocytophilum seropositivity compared with urban and rural areas; and there was a significant spatial cluster of rickettsiae within greater Los Angeles. Animals in areas where urban and rural habitats interconnect can serve as sentinels during times of change in disease risk.

ABSTRACT

California has the highest proportion of unhoused individuals in the country, and up to 25% of unhoused individuals own pets, providing substantial benefits but unique challenges including access to housing, transportation and unfounded grounds for social stigmatization. Unhoused individuals and pets may also be at risk for diseases due to impaired access to sanitation facilities. The purpose of this cross-sectional survey was to evaluate differences in perceived benefits, challenges and public perceptions among pet owners of varying housing security and the prevalence of diseases among their pets. Questionnaires were administered to housed and unhoused pet owners and pet blood screened for rickettsiosis, bartonellosis, ehrlichiosis, anaplasmosis, borreliosis, West Nile fever and heartworm. Among 147 canine and 16 feline blood samples, seropositivity of ectoparasitic diseases did not vary by housing status. Among 45 housed and 56 unhoused owners, unhoused owners were significantly more likely to report protective benefits, challenges obtaining housing, finding a flea on their pet, using bottled water for their pet and their pet sleeping in their bed. Housed owners were significantly more likely to report companionship and entertainment benefits, challenges with pet sitting and consistently administering parasite preventatives. Similar (96-98%) percentages stated they would not give up their pet for better housing and 31% of housed pet owners believed that people should not own pets if they do not have secure housing. Social stigma against unhoused pet owners is present within the community, requiring education to change public perception and guide policy regarding housing for pet owners experiencing homelessness.
