INDEPENDENT 15/07/16 Russian boy catches the bubonic plague while hunting in Siberian mountains. A 10-year-old boy caught bubonic plague while hunting with his grandfather in Siberian mountains.
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. Bubonic plague caused the Black Death epidemic in the 13th century, killing an estimated 30 per cent of the European population. The unnamed child is in a "serious but stable condition" according to doctors, Mirror reports. Vaccines, enough for at least 15,000, are being rushed to the remote area of Kosh-Agach in the Altai Mountains to combat any potential outbreak. Marmots are known to be susceptible to Bubonic plague and hunting them in Siberia is banned as a result (Reuters) At least 4,000 local residents will be vaccinated as a precaution.

BELOIT DAILY NEWS 16/09/16 Forget about the Bubonic plague: Professor presents on emerging diseases. BELOIT — Don’t kiss a pig.
That message and many other fun knowledge nuggets were part of Beloit College professor Rachel Bergstrom’s presentation on emerging public health threats such as Ebola and Zika. She spoke at a Society for Learning Unlimited (SLU) presentation at First Congregational Church on Thursday morning. Bergstrom explained how microbial adaptation, human susceptibility to infection and changing ecosystems are some of many growing factors in the outbreak of disease in a time when antibiotic production is not keeping up with demand.
"We are running out of antibiotics," Bergstrom said. "All of the last-resort antibiotics are being held onto tightly. Human susceptibility to infection is impacted by microbial adaptation and change. Although the human body is filled with bacteria, having it in the wrong place can also equal infection. “Every time they replicate, they may mutate,” she said.

Suggested citation for this article To the Editor: Plague is known to be endemic in several areas of Mongolia, but transmission to humans seems to play only a minor role because the number of recognized cases is relatively low (Figure) (1).
The first human cases in Mongolia were reported to the World Health Organization in 1980, and <20 human cases have occurred each year since then (2). However, human plague was first reported in 1897 (3), such infections have been documented since the 1940s, and Yersinia pestis can be found in many provinces of Mongolia (Figure; T. Damindorj, pers. comm.) (3,4). CDC EID - FEV 2013 - Au sommaire: Yersinia pestis Plasminogen Activator Gene Homolog in Rat Tissues.

Although our understanding of the pathogenesis of bubonic plague has improved significantly over the last few decades, researchers have still not been able to define the complete set of Y. pestis genes needed for disease or to characterize the mechanisms that enable infection. Here, we generated a library of Y. pestis mutants, each lacking one or more of the genes previously identified as being up-regulated in vivo. We then screened the library for attenuated virulence in rodent models of bubonic plague. Importantly, we tested mutants both individually and using a novel, “per-pool” screening method that we have developed. Author Summary In order to understand and combat infectious diseases, it is essential to characterize the full set of genes required by pathogenic bacteria to overcome the many immunological and physiological challenges encountered during infection.

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.

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.

PLOS 28/11/12 Yersinia pestis: New Evidence for an Old Infection. 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.

Its causative agent Yersinia pestis relies on wild rodent hosts and flea vectors for its maintenance in nature. Climate influences all three components (i.e., bacteria, vectors, and hosts) of the plague system and is a likely factor to explain some of plague's variability from small and regional to large scales.
Here, we review effects of climate variables on plague hosts and vectors from individual or population scales to studies on the whole plague system at a large scale. Figures.

BBC 12/10/11 Black Death genetic code 'built' 12 October 2011Last updated at 18:02 By Matt McGrath Science reporter, BBC World Service The ancient burial site is under what is now the Royal Mint The genetic code of the germ that caused the Black Death has been reconstructed by scientists for the first time. The researchers extracted DNA fragments of the ancient bacterium from the teeth of medieval corpses found in London.
They say the pathogen is the ancestor of all modern plagues. The research, published in the journal Nature, suggests the 14th Century outbreak was also the first plague pandemic in history. Humans have rarely encountered an enemy as devastating as the bacterium, Yersinia pestis. Now scientists have uncovered some of the genetic secrets of the plague, thanks to DNA fragments drilled from the teeth of victims buried in a graveyard in London's East Smithfield.
Professor Johannes Krause from the University of Tubingen, Germany, was a member of the research team. Continue reading the main story The plague Tooth power. Nature. 2011 Oct 12;478(7370):506-10.
