Routine surveillance, including the type and distribution of host/vector, host animal density, flea index, and bacteria isolation was performed each year, and the first Y. pestis strain in Guertu was isolated in 1967.
The sentinel site in Guertu was established in 1983. Plague-surveillance staff lived and worked at the sentinel site from May to October each year, when Spermophilus undulatus and Marmota baibacina, the hosts of Y. pestis, emerge from hibernation. Once the sentinel site was established, seropositivity rate was also measured. Biosafety and Health Volume 1, Issue 2, September 2019, Yersinia pestis, a problem of the past and a re-emerging threat.

Luboobi, Y. Nkansah-GyekyeThe effect of seasonal weather variation on the dynamics of the plague disease M. PARASITES & VECTORS 06/11/19 First detection of the kdr mutation (L1014F) in the plague vector Xenopsylla cheopis (Siphonaptera: Pulicidae) Detection of kdr mutations Sequencing of each amplicon resulted in a clear 369-bp sequence, encompassing two full short introns, a full exon and two partial exons (Fig. 1).
Eight nucleotide polymorphisms in the 369-bp fragments were observed from a total of 111 individuals. No nucleotide variation was observed in the first and last partial exons. One non-synonymous mutation, leading to a deduced amino acid substitution of L (CTT) to F (TTT) at the position corresponding to the amino acid residue 1014 of VGSC of the housefly was detected in the second exon, while other three nucleotide polymorphisms in this exon were synonymous. Four polymorphic sites were found in the two introns in total, without length polymorphism being observed (Fig. 1).

In this area, while Marmota himalayana is the primary host, a total of 18 human plague outbreaks associated with Tibetan sheep (78 cases with 47 deaths) have been reported on the Qinghai-Tibet plateau since 1956. All of the index infectious cases had an exposure history of slaughtering or skinning diseased or dead Tibetan sheep.

Plague is an infectious disease that affects rodents, certain other animals, and humans. It is caused by the Yersinia pestis bacteria. These bacteria are found in many areas of the world, including the United States. How do people become infected with plague? People most commonly acquire plague when they are bitten by a flea that is infected with the plague bacteria. CLINICAL MICROBIOLOGY REVIEWS, Apr. 2004, p. 434–464 Intraspecific Diversity of Yersinia pestis. + Author Affiliations Increased interest in the pathogenic potential of Yersinia pestis has emerged because of the potential threats from bioterrorism. Pathogenic potential is based on genetic factors present in a population of microbes, yet most studies evaluating the role of specific genes in virulence have used a limited number of strains.
For Y. pestis this issue is complicated by the fact that most strains available for study in the Americas are clonally derived and thus genetically restricted, emanating from a strain of Y. pestis introduced into the United States in 1902 via marine shipping and subsequent spread of this strain throughout North and South America. In countries from the former Soviet Union (FSU), Mongolia, and China there are large areas of enzootic foci of Y. pestis infection containing genetically diverse strains that have been intensely studied by scientists in these countries. ↵*Corresponding author.

The Russian is believed to have caught the potentially deadly disease when he cut himself with a knife while skinning a marmot. Marmots are large rodents which are known to be susceptible to carrying the disease. Marmot hunting is banned in the area due to the risk of catching bubonic plague but the ban is widely ignored.

MMN 22/08/14 Bubonic plague found in Colorado fleas. Colorado health officials have issued a warning to Boulder County residents after bubonic plague was found in fleas taken from a prairie dog. Flea samples were taken from a Boulder property when a homeowner notified officials of several dead prairie dogs on the property. The neighborhood has been posted with signs warning residents to protect themselves and their pets.
The plague has been active in the area every year since 2005, according to Heather Swanson, a wildlife ecologist for Boulder Open Space and Mountain Parks, but this is the first confirmed case in the county since 2011, when a pet cat and a dead squirrel tested positive for it.

IOWA STATE UNIVERSITY - 2012 - Thèse en ligne : New tools for studying mal gene regulation in Yersinia pestis. Abstract Y. pestis, the etiologic agent of plague, is a significant human pathogen because of its historic role as the cause of three major pandemics and its current role as a potential bioterrorism agent. Gene regulation in this organism is complex and multiple microarray studies have shown that the expression of several genes is affected by quorum sensing as well as temperature. Maltose utilization genes are of particular interest because they are regulated by both of these systems. In order to perform genetic studies on mal genes, and to better understand gene expression in general in Y. pestis, we developed a number of new tools that comprise the majority of the work in this thesis. To take advantage of recombineering as a useful system for constructing new mutants, we improved the protocol to promote a higher efficiency of survival and recombination in electroporated Y. pestis cells.

The successful reconstruction of an ancient bacterial genome from archaeological material presents an important methodological advancement for infectious disease research.
The reliability of evolutionary histories inferred by the incorporation of ancient data, however, are highly contingent upon the level of genetic diversity represented in modern genomic sequences that are publicly accessible, and the paucity of available complete genomes restricts the level of phylogenetic resolution that can be obtained. Here we add to our original analysis of the Yersinia pestis strain implicated in the Black Death by consolidating our dataset for 18 modern genomes with single nucleotide polymorphism (SNP) data for an additional 289 strains at over 600 positions.
