Plague Manual for Investigation
Plague Summary Plague is a flea-transmitted bacterial infection of rodents caused by Yersinia pestis. Fleas incidentally transmit the infection to humans and other susceptible mammalian hosts. Humans may also contract the disease from direct contact with an infected animal. The most common clinical form is acute regional lymphadenitis, called bubonic plague. Less common clinical forms include septicemic, pneumonic, and meningeal plague. Pneumonic plague can be spread from person to person via airborne transmission, potentially leading to epidemics of primary pneumonic plague. Plague is immediately reportable to the New Mexico Department of Health. Plague is treatable with antibiotics, but has a high fatality rate with inadequate or delayed treatment. Plague preventive measures include: isolation of pneumonic plague patients; prophylactic treatment of pneumonic case contacts; avoiding contact with rodents and their fleas; reducing rodent harborage around the home; using flea control on pets; and, preventing pets from hunting. Agent Plague is caused by Yersinia pestis, a gram-negative, bi-polar staining, non-motile, non-spore forming coccobacillus. Transmission Reservoir: Wild rodents (especially ground squirrels) are the natural vertebrate reservoir of plague. Lagomorphs (rabbits and hares), wild carnivores, and domestic cats may also be a source of infection to humans. Vector: In New Mexico, the rock squirrel flea, Oropsylla montana, is the most important vector of plague for humans. Many more flea species are involved in the transmission of sylvatic (wildlife) plague. Mode of Transmission: Most humans acquire plague through the bites of infected fleas. Fleas can be carried into the home by pet dogs and cats, and may be abundant in woodpiles or burrows where peridomestic rodents such as rock squirrels (Spermophilus variegatus) have succumbed to plague infection. -

Black-Tailed Prairie Dogs
Black-tailed Prairie Dogs Land Stewardship Information Series Prairie Dogs in Jeffco Identification Black-tailed prairie dogs (Cynomys ludovicianus) are medium-sized burrowing rodents with tan fur and whitish bellies. They are about 12-15 inches long and weigh between 2-4 pounds. The tips of their short tails have black markings. Ecosystem Black-tailed prairie dogs are found at elevations below 6000 feet, east of the foothills. They feed mainly on grasses and forbs but will occasionally feed on insects. They clip taller plants close to the ground to provide a clear view of their surroundings. The clipped grass is left on the ground or may be used to line underground chambers. Prairie dogs dig tunnels below the soil surface. The tunnels are about 6 feet underground and can be about 15 yards long with two or more entrances. The system provides shelter, protection from predators, and nesting sites. The tunnel entrances are mound-shaped which prevents water from draining in and provides an elevated perch to watch their surroundings. Prairie dogs are active during the day. They do not hibernate but will stay in their burrows during extremely cold or hot days. A healthy prairie dog town will have diverse and balanced native vegetation. In urban areas, many prairie dog towns are fragmented and confined by human development.As a result of this confinement, vegetation can become denuded and the resulting disturbance allows invasive and noxious weeds to predominate. These changes affect how the prairie Quick Facts ecosystem functions and can fundamentally change the plants and animals that live there. -
Status Review Finding for the Black-Tailed Prairie Dog
QUESTIONS AND ANSWERS REGARDING THE STATUS REVIEW FINDING FOR THE BLACK-TAILED PRAIRIE DOG What are the findings of the black-tailed prairie dog status review? The U.S. Fish and Wildlife Service has completed a status review of the black-tailed prairie dog and has determined it does not warrant protection as a threatened or endangered species under the Endangered Species Act. The Service bases its conclusion for this finding after a thorough review of all the available scientific and commercial information regarding the status of the black-tailed prairie dog and the potential impacts to the species. What is a status review? A status review, also known as a 12-month finding, makes public the Service=s decision on a petition to list a species as threatened or endangered under the Endangered Species Act. The finding is based on a thorough assessment of the available information on the species, as detailed in the species= status review. One of three possible conclusions can be reached as part of the finding: that listing is warranted, not warranted, or warranted but presently precluded by other higher-priority listing activities involving other species. In the case of black-tailed prairie dog, the Service found that the black-tailed prairie dog is not likely to become a threatened or endangered species within the foreseeable future in all or a significant portion of its range. Therefore, listing of the black-tailed prairie dog as a threatened or endangered species under the Endangered Species Act is not warranted at this time. What specifically does the Service look at to determine if a species needs to be listed as threatened or endangered? We consider the factors specified in the Endangered Species Act to determine whether a species meets the definition of “threatened” or “endangered” per the criteria stated in the Act. -
Human Plague Cases Reported Worldwide, Including in US
ID Snapshot, Infectious Diseases ID Snapshot: Human plague cases reported worldwide, including in U.S. by H. Cody Meissner M.D., FAAP The largest epidemic of plague occurred between 1348 and 1351 in Europe. Medieval ships returning from Asia were swarming with infected rats that climbed ashore once in port. The infection spread from rats to fleas and from fleas to rats. Infection spread to humans after large numbers of infected rats died, forcing hungry fleas to bite other hosts. Dressed in a gown made of heavy, waxed fabric, the plague doctor also wore goggles and a mask with a beak that contained pungent substances to purify the air and help relieve the stench. The person also carried a pointer or rod to keep patients at a distance. Illustration courtesy of the U.S. National Library of Medicine This pandemic of the Black Death (named after the purpuric lesions associated with disseminated intravascular coagulation) in the 14th century spread to every country in Europe killing one-third of the population. Doctors wore a costume (see illustration) when visiting patients. The mask and hat were intended to look like a deity to scare off the disease. The beak was filled with herbs and perfumes to offer protection against the unbearable stench. The long waxed raincoat and gloves were designed to prevent physical contact with a patient. One theory suggests the epidemic ended when the rodent reservoir in Europe (black rat) was replaced by the brown rat, which was not as prone to transmit the infection. Which one of the following statements about plague is not accurate? Copyright © 2016, The American Academy of Pediatrics ID Snapshot, Infectious Diseases a) Plague is a rare, life-threatening, flea-borne zoonosis caused by Yersinia pestis. -

Nepotism in Prairie Dogs (Cynomys Ludovicianus) Varies with Competition but Not with Kinship
Anim . Behar ., 1986, 34, 263-270 Nepotism in prairie dogs (Cynomys ludovicianus) varies with competition but not with kinship JOHN L . HOOGLAND* Department of Biology, Princeton University, Princeton, New Jersey 08544, U .S .A . Abstract. Behavioural interactions among black-tailed prairie dogs (Cynomys ludovicianus) of the same sex clearly show nepotism (the favouring of kin) . Males and females consistently interact more amicably with kin than with non-kin . Nepotism in this context is striking for two reasons . First, individuals do not interact more amicably with close kin such as offspring and full-siblings than with more distant kin such as half-siblings, full-nieces, half-nieces, and half-nephews . Second, nepotism varies inversely and dramati- cally with changes in competition for either oestrous females (among males) or nesting burrows and breeding rights (among females) . Nepotism is the preferential treatment of genetic document, has been reported for only a few species relatives (Alexander 1974; Sherman 1980a), and including sweat bees (Lasioglossum °ephyrum : parental care is one obvious expression of nepo- Greenberg 1979 ; Buckle & Greenberg 1981), Beld- tism .

Controlling Plague in Gunnison's Prairie Dogs
COLORADO PARKS & WILDLIFE Plague in Gunnison’s Prairie Dogs MAY 2014 Controlling Plague in Gunnison’s Prairie Dogs Plague, caused by a non-native bacteria and carried by fleas can kill all prairie dogs in a colony, leading to local extinctions that threaten the overall survival of the Gunnison’s prairie dog (Cynomys gunnisoni) in Colorado. Unmanaged plague has the potential to reduce populations of the Gunnison’s prairie dog to the point that a listing as federally endangered or threatened becomes more likely. Such a listing would not only underscore the need for additional conservation, it could also limit land uses for agriculture and recreation. The Gunnison’s prairie dog serves key roles in southwest Colorado’s biological landscapes: • A food source for many wildlife species including raptors and mammalian carnivores. • Prairie dog colonies serve as habitat for mountain plover, burrowing owl, badger, weasel, snakes and other wildlife species. Research Objectives Since the Gunnison’s prairie dog is an important species in the state’s ecosystem, Colorado Parks and Wildlife (CPW) has determined that controlling plague in this species is a priority conservation action. The CPW goal is to develop plague management tools to help manage and stabilize Gunnison’s prairie dog populations on public lands and in cooperation with willing landowners. CPW Plague Control Research Success The U.S. Geological Survey’s National Wildlife Health Center developed a sylvatic plague vaccine (SPV) and tested the vaccine in the lab in 2010. That laboratory research demonstrated that the vaccine is safe and protects prairie dogs from plague. Field trials are necessary to confirm these findings in the wild. -
