A plague (Yersinia pestis) epizootic spread through Gunnison's prairie dogs (Cynomys gunnisoni), and possibly other rodent species, in the Moreno Valley in north-central New Mexico between winter 1984-1985 and autumn 1987. We observed the progress of the epizootic and subsequent population recovery at four prairie dog towns within the valley during this(More)

Between 1972 and March 1977, 367 cultures of Yersinia enterocolitica were examined for biotypic and serotypic characteristics by Plague Branch, Vector-Borne Diseases Division, Center for Disease Control. Standard biotyping tests were performed. Serotyping antisera used contained somatic serofactors 1 through 9, 11 through 21, 24, 32, and two new types(More)
From 1970 to 1991, 295 indigenous cases and one imported case of human plague were reported in the United States. Eighty-two percent of the total indigenous cases occurred in New Mexico, Arizona, and Colorado. Ninety-three percent of these cases had onset in the months of April through November. Most cases (89%) presented as bubonic or septicemic plague, or(More)
An 11-year-old boy developed axillary bubonic plague and plague meningitis 3 days after skinning a dead coyote near Albuquerque, New Mexico. The coyoto carcass was recovered 10 days later, and Yersinia pestis was isolated from spleen and marrow of the animal. This is the first report of human plague from exposure to a coyote. A review of experimental and(More)
The laboratory-born progeny from two geographically distant populations of northern grasshopper mice (Onychomys leucogaster) were challenged with Yersinia pestis to determine their relative susceptibilities to plague. One of the O. leucogaster populations was associated with a known epizootic focus of the disease and was found to be nearly 2,000 times more(More)
Yersinia pestis possesses a unique gene (pla) encoding coagulase and fibrinolysin which is implicated in the transmission of plague by fleas. This gene is encoded on the highly conserved but poorly characterized 'pesticin' plasmid pKYP1. The role of the pKYP1-encoded gene, pla, in plague transmission was addressed by feeding fleas on blood containing(More)
Sixteen healthy cats were fed a 6-wk-old laboratory mouse that had died of experimentally induced Yersinia pestis infection (strain NM77-538), to simulate oral exposure to plague. The cats were closely monitored after ingestion. Physical exams were performed and vital signs were recorded daily. Plague antibody titers and cultures of blood, throat, and oral(More)
Meningitis caused by Yersinia pestis developed in 6 (6%) of a total of 105 patients with plague reported to the Centers for Disease Control from 1970 to 1979. Five of the six cases occurred in children aged 10 to 15 years. All six patients received antibiotic therapy before meningitis developed, which appeared between the 9th and 14th days after the onset(More)
Eight domestic ferrets (Mustela putorius furo) and two Siberian polecats (M. eversmanni) were inoculated subcutaneously with 12 to 1.2 x 10(7) Yersinia pestis originally isolated during an epizootic of plague in white-tailed prairie dogs (Cynomys leucurus) near Meeteetse, Park County, Wyoming (USA) in 1985. None of the ferrets or polecats developed clinical(More)
