Yersiniosis is an infectious disease of the gastrointestinal tract caused by bacteria of the genus Yersinia other than Y. pestis. Most cases of yersiniosis in humans are caused by Y. enterocolitica , with a small minority being caused by Y. pseudotuberculosis .
The disease caused by Y. enterocolitica is called yersiniosis. Yersinia may be associated with Crohn's disease, an inflammatory autoimmune condition of the gut. Iranian people with Crohn's disease were more likely to have had earlier exposure to refrigerators at home, [6] consistent with its unusual ability to thrive at low temperatures.
The MacConkey plates employ the fact that Y. enterocolitica is non-lactose fermenting, and therefore show up on the plates as 2mm translucent pale colonies. On Yersinia Selective Agar plates Y. enterocolitica produces 1.5mm colonies with a dark pink center and translucent border. [6] [5]
In animals, Y. pseudotuberculosis can cause tuberculosis-like symptoms, including localized tissue necrosis and granulomas in the spleen, liver, and lymph nodes. In humans, symptoms of Far East scarlet-like fever are similar to those of infection with Yersinia enterocolitica (fever and right-sided abdominal pain), except that the diarrheal component is often absent, which sometimes makes the ...
President Trump signed an executive order Tuesday to expand his control over “so-called independent agencies” in a bid to rein in regulatory departments — including the Federal Trade ...
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.
Bubonic plague is one of three types of plague caused by the bacterium Yersinia pestis. [1] One to seven days after exposure to the bacteria, flu-like symptoms develop. [1] These symptoms include fever, headaches, and vomiting, [1] as well as swollen and painful lymph nodes occurring in the area closest to where the bacteria entered the skin. [2]
Even though the ostrich is a bird, it can’t fly. Ostriches have wings, of course, but they are too small to support their weight. In addition, birds need keel-shaped sternums for flight, and ...
