Wild Felids as Hosts for Human Plague, Western United States
نویسندگان
چکیده
Plague seroprevalence was estimated in populations of pumas and bobcats in the western United States. High levels of exposure in plague-endemic regions indicate the need to consider the ecology and pathobiology of plague in nondomestic felid hosts to better understand the role of these species in disease persistence and transmission.

Interannual variability of human plague occurrence in the Western United States explained by tropical and North Pacific Ocean climate variability.
Plague is a vector-borne, highly virulent zoonotic disease caused by the bacterium Yersinia pestis. It persists in nature through transmission between its hosts (wild rodents) and vectors (fleas). During epizootics, the disease expands and spills over to other host species such as humans living in or close to affected areas. Here, we investigate the effect of large-scale climate variability on ...
متن کاملModeling the ecologic niche of plague in sylvan and domestic animal hosts to delineate sources of human exposure in the western United States
Plague has been established in the western United States (US) since 1900 following the West Coast introduction of commensal rodents infected with Yersinia pestis via early industrial shipping. Over the last century, plague ecology has transitioned through cycles of widespread human transmission, urban domestic transmission among commensal rodents, and ultimately settled into the predominantly s...
متن کاملThe Role of Predators in the Ecology, Epidemiology, and Surveillance of Plague in the United States
Predators play important roles in the ecology, epidemiology, and surveillance of plague in the United States. Most predators are accidental hosts of plague and, with the possible exception of grasshopper mice (Onychomys spp.), are not important sources of infection for feeding fleas. However, predators undoubtedly do play an important role in the natural cycle of plague by transporting infected...
متن کاملPlague in the U.s.: Present and Future
An increasing trend in the frequency of human bubonic plague cases in the United States, the principal sources of human infection, and emerging control techniques are described. Development of an integrated control program involving public health education, citizen participation in plague surveillance, and insecticidal control of flea vectors in response to evidence of plague and potential huma...
متن کاملRodent Population Control for Public Health and Safety
Rodent populations particularly those that live in close proximity to man constitute a perennial and often severe threat to man's health as reservoirs and often as direct sources of infection for a wide variety of viral, rickettsial, and bacterial disease producing agents. The following will discuss the place of rodent population reduction for the control of plague, a bacterial disease of roden...
