Providencia

A genus of motile, peritrichous, nonsporeforming, aerobic or facultatively anaerobic bacteria (family Enterobacteriaceae) containing Gram-negative rods. These organisms do not hydrolyze urea or produce hydrogen sulfide; they produce indole and grow on Simmons citrate medium. They do not decarboxylate lysine, arginine, or ornithine. These organisms occur in specimens from extraintestinal sources, particularly urinary tract infections; they have also been isolated from small outbreaks and sporadic cases of diarrheal disease. The type species is P. alcalifaciens.
