possible vector dissemination by swift foxes following a plague epizootic in black-tailed prairie dogs in northwestern determine whether swift foxes (vulpes velox) could facilitate transmission of yersinia pestis to uninfected black-tailed prairie dog (cynomys ludovicianus) colonies by acquiring infected fleas, ectoparasite and serologic samples were collected from swift foxes living adjacent to prairie dog towns during a 2004 plague epizootic in northwestern texas, usa. a previous study (1999-2001) indicated that these swift foxes were infested almost exclusively with the flea pulex irritans. black-tailed pr ...200616870868
the potential role of swift foxes (vulpes velox) and their fleas in plague outbreaks in prairie dogs.swift foxes (vulpes velox) have been proposed as potential carriers of fleas infected with the bacterium yersinia pestis between areas of epizootics in black-tailed prairie dogs (cynomys ludovicianus). we examined antibody prevalence rates of a population of swift foxes in colorado, usa, and used polymerase chain reaction (pcr) assays to examine their flea biota for evidence of y. pestis. fifteen of 61 (24%) captured foxes were seropositive, and antibody prevalence was spatially correlated with ...200717699080
flea abundance on black-tailed prairie dogs (cynomys ludovicianus) increases during plague prairie dogs (cynomys ludovicianus) on the great plains of the united states are highly susceptible to plague, caused by the bacterium yersinia pestis, with mortality on towns during plague epizootics often approaching 100%. the ability of flea-borne transmission to sustain disease spread has been questioned because of inefficiency of flea vectors. however, even with low individual efficiency, overall transmission can be increased if flea abundance (the number of fleas on hosts) inc ...200919492944
prevalence of the generalist flea pulex simulans on black-tailed prairie dogs (cynomys ludovicianus) in new mexico, usa: the importance of considering imperfect detection.if a parasite is not detected during a survey, one of two explanations is possible: the parasite was truly absent or it was present but not detected. we fit occupancy models to account for imperfect detection when combing fleas (siphonaptera) from black-tailed prairie dogs (cynomys ludovicianus) during june-august 2012 in the vermejo park ranch, new mexico, usa. with the use of detection histories from combing events during monthly trapping sessions, we fit occupancy models for two flea species: ...201525588009
