July 27th – Enterobacter cloacae is a clinically significant Gram-negative, facultatively-anaerobic, rod-shaped bacterium. Enterobacter cloacae is a member of the normal gut flora of many humans and is not usually a primary pathogen. Some strains have been associated with urinary tract and respiratory tract infections in immunocompromoised individuals. Treatment with cefepime and gentamicin has been reported. A 2012 study in which Enterobacter cloacae transplanted into previously germ-free mice resulted in increased obesity when compared with germ-free mice fed an identical diet, suggesting a link between obesity and the presence of Enterobacter gut flora.
