Endosteaalisella

Endosteaalisella is a genus of bacteria from the family Enterobacteriaceae, first described in 2014. It is a Gram-negative, facultatively anaerobic, rod-shaped bacterium that is commonly found in the gastrointestinal tract of humans and other mammals. The genus includes two species, Endosteaalisella avium and Endosteaalisella massiliensis, both of which are opportunistic pathogens.

Endosteaalisella avium is associated with various clinical conditions, including urinary tract infections, bacteremia, and sepsis. It is also known to cause infections in immunocompromised individuals and those with underlying health conditions. Endosteaalisella massiliensis has been isolated from clinical specimens, but its clinical significance is less well understood.

The genus Endosteaalisella is characterized by its ability to ferment glucose and produce acid from various carbohydrates. It is also known for its resistance to certain antibiotics, including ampicillin and trimethoprim-sulfamethoxazole. The genus is named after the Greek words "endo," meaning within, and "stea," meaning star, reflecting the star-like appearance of the bacterium under a microscope.

Endosteaalisella is typically diagnosed through culture and identification methods, such as matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). Treatment of Endosteaalisella infections may involve the use of antibiotics, such as third-generation cephalosporins or carbapenems, depending on the specific species and the severity of the infection.
