Bacterium tularense was soon isolated by George Walter McCoy (1876–1952) of the US Plague Lab in San Francisco and reported in 1912. In 1922, Edward Francis (1872–1957), a physician and medical researcher from Ohio, discovered that Bacterium tularense was the causative agent of tularemia, after studying several cases with symptoms of the ...
According to author Philip Norrie (How Disease Affected the End of the Bronze Age), there are three diseases most likely to have caused a post-Bronze Age societal collapse: smallpox, bubonic plague, and tularemia. The tularemia plague which struck the Hittites could have been spread by insects or infected dirt or plants, through open wounds, or ...
The most infamous flea-to-human transmitted disease is the bubonic plague, which was caused by the bacterium Yersinia pestis. The plague, fevers, tularemia: The diseases fleas can carry and how to ...
Lab tests are not always relied upon because treatment may be necessary before the results are returned. [23] Abnormal laboratory findings seen in patients with Rocky Mountain spotted fever may include a low platelet count, low blood sodium concentration, or elevated liver enzyme levels. Serology testing and skin biopsy are considered to be the ...
It was later revealed that laboratory and field testing (some of the latter using simulants on non-consenting individuals) had been common. The official policy of the United States was first to deter the use of bio-weapons against U.S. forces and secondarily to retaliate if deterrence failed.
Yersinia pestis (Y. pestis; formerly Pasteurella pestis) is a gram-negative, non-motile, coccobacillus bacterium without spores that is related to both Yersinia enterocolitica and Yersinia pseudotuberculosis, the pathogen from which Y. pestis evolved [1] [2] and responsible for the Far East scarlet-like fever.
It is known to cause wound infections and other species of its genera are known to cause urinary tract infections. P. vulgaris was one of the three species Hauser isolated from putrefied meat and identified (1885). Over the past two decades, the genus Proteus, and in particular P. vulgaris, has undergone a number of major taxonomic revisions.
