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… 

FLEA ABUNDANCE, DIVERSITY, AND PLAGUE IN GUNNISON'S PRAIRIE DOGS (CYNOMYS GUNNISONI) AND THEIR BURROWS IN MONTANE GRASSLANDS IN NORTHERN NEW MEXICO

TLDR
A significant surge in flea abundance and prevalence, particularly within burrows, following plague exposure is found, hypothesize that the role of burrows as a site of flea exchange, particularly between prairie dogs and ground squirrels, may be as important as summer conditions that lead to buildup in O. hirsuta populations for determining plague outbreaks.

Prevalence of Yersinia pestis in Rodents and Fleas Associated with Black-tailed Prairie Dogs (Cynomys ludovicianus) at Thunder Basin National Grassland, Wyoming

TLDR
It is confirmed that plague is difficult to detect in rodents and fleas associated with prairie dog colonies, unless samples are collected immediately after a prairieDog die-off, as well as for the presence of the plague bacterium.

Exposure of Small Rodents to Plague during Epizootics in Black-tailed Prairie Dogs

TLDR
The results suggest that grasshopper mice could be involved in epizootic spread of Y. pestis, and possibly, serve as a short-term reservoir for plague, but provide no evidence that the Grasshopper mouse or any small rodent acts as a long-term, enzootic host for Y. pests.

Evidence for the involvement of an alternate rodent host in the dynamics of introduced plague in prairie dogs.

TLDR
It is speculated that grasshopper mice help spread Y. pestis during epizootics through their ability to survive infection, harbour prairie dog fleas and, during their wide-ranging movements, transport infected fleas among burrows, which functionally connects prairieDog coteries that would otherwise be socially distinct.

A PLAGUE EPIZOOTIC IN THE BLACK-TAILED PRAIRIE DOG (CYNOMYS LUDOVICIANUS)

TLDR
Black-tailed prairie dogs are capable of surviving a plague epizootic and reorganizing into apparently functional coteries, and may be critical in the repopulation of plague-decimated colonies and, ultimately, the evolution of plague resistance.

No evidence of deer mouse involvement in plague (Yersinia pestis) epizootics in prairie dogs.

TLDR
The results suggest that the deer mouse is an unlikely maintenance host of plague in this region, where plague is active in prairie dog colonies.

INTERSPECIFIC COMPARISONS OF SYLVATIC PLAGUE IN PRAIRIE DOGS

TLDR
Major effects of plague are to reduce colony size of black-tailed prairie dogs and increase intercolony distances within colony complexes and epidemiologic concepts are used to support an enzootic hypothesis in which the disease is maintained in a dynamic state.

Prevalence and Abundance of Fleas in black-tailed Prairie Dog Burrows: Implications for the Transmission of Plague (Yersinia pestis)

TLDR
During plague epizootics, flea abundance in burrows increased and then subsequently declined after the extirpation of their prairie dog hosts, and Oropsylla hirsuta was the most commonly found flea, and it increased in abundance with temperature.

No Evidence of Persistent Yersina pestis Infection at Prairie Dog Colonies in North-Central Montana

TLDR
This and other studies provide evidence that Y. pestis may not persist at prairie dog colonies following an epizootic and suggest that the plague organism persists locally among resistant host species or elsewhere followingEpizootics.

Species Diversity and Host Specificity in Flea Communities from the Two Subspecies of the Gunnison's Prairie Dog (Cynomys gunnisoni)

  • L. Crane
  • Environmental Science, Biology

TLDR
An Analysis of Molecular Variance revealed that most of the genetic variation in the COII sequences exists among fleas occurs within a colony, and that there is also significant variance among colonies, suggesting that fleas do not discriminate between the two subspecies.

Growth and Life-History Changes in Gunnison's Prairie Dogs after a Plague Epizootic

TLDR
Application of observed demographic parameters to Leslie-matrix analysis indicated that projected size of population was declining at site 1 and was tripling annually at sites 2 and 3, and the difference in λ was mostly due to increased survivorship of juveniles and reproduction at an earlier age in the new towns.

Susceptibility of New Mexico rodents to experimental plague.

TLDR
Until both factors, vector potential and host susceptibility, are determined, the ecology of sylvatic plague will be difficult to understand.
