Tularemia, also known as rabbit fever, is an infectious disease caused by the bacterium Francisella tularensis. [4] Symptoms may include fever , skin ulcers , and enlarged lymph nodes . [ 3 ] Occasionally, a form that results in pneumonia or a throat infection may occur.
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 ...
Tularemia is a bacterial infection which is still a threat. [1] It is also referred to as "rabbit fever" and it is a zoonotic disease which can easily pass from animals to humans. The most common way that it is spread is through various insects which hop between species, such as ticks. [ 3 ]
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 ...
Pathophysiology (or physiopathology) is a branch of study, at the intersection of pathology and physiology, concerning disordered physiological processes that cause, result from, or are otherwise associated with a disease or injury.
The epiblast was first discovered by Christian Heinrich Pander (1794-1865), a Baltic German biologist and embryologist. With the help of anatomist Ignaz Döllinger (1770–1841) and draftsman Eduard Joseph d'Alton (1772-1840), Pander observed thousands of chicken eggs under a microscope, and ultimately discovered and described the chicken blastoderm and its structures, including the epiblast.

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.
