Fleas are known to carry a number of diseases that are transferable to humans through their bites, including plague, caused by the bacterium Yersinia pestis
But in recent years, the pathogen's genetic traces have been found in sixth-century graves, and the DNA evidence convicts Yersinia pestis
of this ancient mass murder as definitively as it would in a modern courtroom.
Relationship between virulence and immunity as revealed in recent studies of the F1 capsule of Yersinia pestis
Dogs have been known to pass yersinia pestis
on to their owners.
Plague is a bacterial disease of rodents caused by Yersinia pestis
, and approximately 90% of cases are reported from Africa.
From the several pandemics generally called 'pestilences' three are historically recognized as due to plague, but only for the third pandemic of the 19th-21st centuries AD there were microbiological evidences that the causing agent was the bacterium Yersinia pestis
Summary: TEHRAN (FNA)- The plague-causing bacteria Yersinia pestis
evades detection and establishes a stronghold without setting off the body's early alarms.
Microbiologists, infectious disease specialists, pathologists, and other medical researchers draw on principles and techniques of systems biology to study Yersinia pestis
, the bacteria that causes the bubonic plague, and other members of the genus Yersinia.
The bacterium that causes the plague, Yersinia pestis
, still exists, though the disease occurs rarely these days, and when it does it is seldom lethal.
The researchers, from Canada and Germany, confirmed a long-held belief that the bacterium Yersinia pestis
was the source of the epidemic, later identified as bubonic plague.
The contract includes preclinical efficacy and toxicology studies, clinical studies, manufacturing, and associated regulatory activities for TP-434 as a potential treatment of inhalation-al disease caused by Bacillus anthracis, Francisella tularensis and Yersinia pestis
The researchers found that a specific strain of the plague bug Yersinia pestis
caused the pandemic that killed 100 million Europeans - between 30% and 50% of the total population - in just five years between 1347 and 1351.
