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 period. At two towns (Midlake and Val Verde) the prairie dogs were marked prior to the epizootic. At two additional towns (Vega and South Entrance) prairie dogs were marked following the epizootic. In 1988, a second epizootic occurred at Vega. One hundred thirty-nine serum samples were collected from prairie dogs and other rodents and 1,750 fleas were collected from...

We conducted a natural removal experiment, utilizing a local outbreak of sylvatic plague (Yersinia pestis) as the removal agent, to test the effects of removal of Gunnison's prairie dogs (Cynomys gunnisoni) on plant and nocturnal rodent assemblages in three grassland habitats (ponderosa, pinyon-juniper, and desert grasslands) in northern Arizona. We measured plant cover, rodent abundance, plant and rodent species richness, and plant and rodent composition at three treatment locations: active prairie dog colonies (n=15), inactive colonies (n=15), and control locations (n=15). Only the amount of plant cover differed significantly among treatments. As landscape level heterogeneity among habitat types increased, rodent...

Data on the degree and duration of deltamethrin flea control on prairie dog colonies, with 3 prairie dog species at 6 sites across 3 US states. Fleas were combed (COMB) from live-trapped prairie dogs or swabbed (SWAB) from prairie dog burrows on non-treated (Non) sites and nearby sites treated with deltamethrin dust for flea control (Dusted). Each line of data is from an individual prairie dog or burrow. The first set of data, Shortterm BACI, includes data from before-after-control-impact (BACI) experiments comparing the abundance of fleas on prairie dogs at paired non-treated and treated sites in 2 time intervals: before treatments (Before) and 2 to 65 days after treatments (After). The second set of data, Moderate...
Data were collected to investigate effects of deltamethrin and fipronil on ectoparasites from black-tailed prairie dogs in South Dakota, USA. In late-July 2018, we treated 3 sites with 0.05% deltamethrin dust and 5 sites with host-fed 0.005% fipronil grain. Three non-treated sites functioned as experimental baselines. We collected ectoparasites before treatments (June-July 2018) and after treatments (August-October 2018, June-July 2019). We combed ectoparasites from live-trapped, anesthetized prairie dogs. Trapping on treated and non-treated sites occurred simultaneously or nearly simultaneously in each year. Detected ectoparasites were counted and placed back on the prairie dogs from which they were collected to...
Of the 3 major factors (habitat loss, poisoning, and disease) that limit abundance of prairie dogs today, sylvatic plague caused by Yersinia pestis is the I factor that is beyond human control. Plague epizootics frequently kill > 99% of prairie dogs in infected colonies. Although epizootics of sylvatic plague occur throughout most of the range of prairie dogs in the United States and are well described, long-term maintenance of plague in enzootic rodent species is not well documented or understood. We review dynamics of plague in white-tailed (Cynomys leucurus), Gunnison's (C gunnisoni), and black-tailed (C ludovicianus) prairie dogs, and their rodent and flea associates. We use epidemiologic concepts to support...

In 2013, a large blinded, paired placebo-controlled field trial for the prairie dog oral sylvatic plague vaccine started in the Western US. On 17 paired plots, vaccine and placebo plots, small rodents were trapped annually for 3-5 consecutive nights (when weather allowed) and high elevation Utah plots where plague was active were more frequently trapped in 2014 and 2015. In the dataset the prevalence of flea infestation was recorded for the first annual summer sampling, it was summarized for all small rodent species caught and deer mice (Peromyscus maniculatus). Infestations were either for all flea species collected or for Aetheca wagneri only (our most abundant flea species). We used this data to assess if plague...
