epidemiologisella

Epidemiologisella is a genus of bacteria from the family Enterobacteriaceae. It is a Gram-negative, facultatively anaerobic, rod-shaped bacterium. The genus was first described in 1999 and currently includes two species: Epidemiologisella asaccharolytica and Epidemiologisella flava. These bacteria are opportunistic pathogens, meaning they can cause infections in individuals with weakened immune systems, such as those with diabetes, cancer, or those undergoing chemotherapy. They are also known to be part of the normal microbiota in the human gut. Epidemiologisella species are characterized by their ability to ferment a variety of carbohydrates, including glucose, fructose, and sucrose, but not lactose. They are also known to produce hydrogen sulfide, which can contribute to the characteristic odor of some types of cheese. The genus name Epidemiologisella is derived from the Greek words "epidemiologos," meaning "epidemiologist," and "bacterion," meaning "bacterium," reflecting the role of these bacteria in epidemiological studies.
