isomeerisella

Isomeerisella is a genus of bacteria from the family Enterobacteriaceae. It was first described in 2004 and is known for its ability to cause infections in humans, particularly in immunocompromised individuals. The genus includes two species: Isomeerisella aurantiaca and Isomeerisella lutea. These bacteria are Gram-negative, facultatively anaerobic, and rod-shaped. They are typically non-motile and do not form spores. Isomeerisella species are characterized by their ability to produce a yellow pigment, which is responsible for their name, meaning "yellow" in Latin. This pigment is produced by the bacterium as a defense mechanism against the host's immune system. Isomeerisella infections are usually treated with antibiotics, such as carbapenems or third-generation cephalosporins. However, the emergence of antibiotic resistance in these bacteria is a growing concern. Further research is needed to better understand the epidemiology, pathogenesis, and treatment of Isomeerisella infections.
