Fecal shedding of zoonotic food-borne pathogens by wild rodents in a major agricultural region of the central California coast.

摘要: Recent outbreaks of food-borne illness associated with the consumption produce have increased concern over wildlife reservoirs pathogens. Wild rodents are ubiquitous, and those living close to agricultural farms may pose a food safety risk should they shed zoonotic microorganisms in their feces near or on commodities. Fecal samples from wild trapped 13 (9 produce, 3 cow-calf operations, 1 beef cattle feedlot) Monterey San Benito Counties, CA, were screened determine prevalence factors for shedding several Deer mice (Peromyscus maniculatus) most abundant rodent species (72.5%). Cryptosporidium (26.0%) Giardia (24.2%) predominant isolates feces, followed by Salmonella enterica serovars (2.9%) Escherichia coli O157:H7 (0.2%). Rodent trap success was significantly detection while farm type fecal Giardia. Seasonal patterns evident, during spring summer months being less likely be oocysts than autumn. Higher diversity tended correlate lower microbial prevalence, spatiotemporal pathogen clusters involved deer mice. Rodents study area posed minimal as environmental E. O157:H7, but play role dissemination protozoa. control efforts that potentially reduce biodiversity increase shedding, possibly through promotion intraspecific transmission.
