plague in a complex of white-tailed prairie dogs and associated small mammals in wyoming.fleas were collected from white-tailed prairie dogs (cynomys leucurus) and other small mammals trapped on six grids during a field study near meeteetse (wyoming, usa) in 1989 and 1990 to investigate the dynamics of plague in this rodent population. fleas were identified and tested for yersinia pestis by mouse inoculation. yersinia pestis-positive fleas were found on prairie dogs and in their burrows. flea species on prairie dogs changed from spring to late summer. white-tailed prairie dog number ...19979391955
prevalence and abundance of fleas in black-tailed prairie dog burrows: implications for the transmission of plague (yersinia pestis).plague, the disease caused by the bacterium yersinia pestis, can have devastating impacts on north american wildlife. epizootics, or die-offs, in prairie dogs (cynomys ludovicianus) occur sporadically and fleas (siphonaptera) are probably important in the disease's transmission and possibly as maintenance hosts of y. pestis between epizootics. we monitored changes in flea abundance in prairie dog burrows in response to precipitation, temperature, and plague activity in shortgrass steppe in north ...200818605787
transmission efficiency of two flea species (oropsylla tuberculata cynomuris and oropsylla hirsuta) involved in plague epizootics among prairie dogs.plague, caused by yersinia pestis, is an exotic disease in north america circulating predominantly in wild populations of rodents and their fleas. black-tailed prairie dogs (cynomys ludovicianus) are highly susceptible to infection, often experiencing mortality of nearly all individuals in a town as a result of plague. the fleas of black-tailed prairie dogs are oropsylla tuberculata cynomuris and oropsylla hirsuta. we tested the efficiency of o. tuberculata cynomuris to transmit y. pestis daily ...200818787922
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
flea abundance, diversity, and plague in gunnison's prairie dogs (cynomys gunnisoni) and their burrows in montane grasslands in northern new mexico.plague, a flea-transmitted infectious disease caused by the bacterium yersinia pestis, is a primary threat to the persistence of prairie dog populations (cynomys spp.). we conducted a 3-yr survey (2004-2006) of fleas from gunnison's prairie dogs (cynomys gunnisoni) and their burrows in montane grasslands in valles caldera national preserve in new mexico. our objectives were to describe flea communities and identify flea and rodent species important to the maintenance of plague. we live-trapped p ...201020688629
detections of yersinia pestis east of the known distribution of active plague in the united states.we examined fleas collected from black-tailed prairie dog (cynomys ludovicianus) burrows from 2009 through 2011 in five national park units east of the known distribution of active plague across the northern great plains for the presence of yersinia pestis. across all national park units, oropsylla tuberculata and oropsylla hirsuta were the most common fleas collected from prairie dog burrows, 42.4% and 56.9%, respectively, of the 3964 fleas collected from burrow swabbing. using a nested pcr ass ...201626771845
