''Proteus penneri'' is a Gram-negative, facultatively anaerobic, rod-shaped bacterium. It is an invasive pathogen and a cause of nosocomial infections of the urinary tract or open wounds. Pathogens have been isolated mainly from the urine of patients with abnormalities in the urinary tract, and from stool. ''P. penneri'' strains are naturally resistant to numerous antibiotics, including penicillin G, amoxicillin, cephalosporins, oxacillin, and most macrolides, but are naturally sensitive to aminoglycosides, carbapenems, aztreonam, quinolones, sulphamethoxazole, and co-trimoxazole. Isolates of ''P. penneri'' have been found to be multiple drug-resistant (MDR) with resistance to six to eight drugs. β-lactamase production has also been identified in some isolates. ==History== The ''Proteus penneri'' group of bacteria was named in 1982. It reclassified a group of strains formerly known as ''Proteus vulgaris'' biogroup 1. In 1978, Brenner ''et al.'' showed through DNA hybridization studies that ''P. vulgaris'' was a heterogenous species. In 1981, Hickman ''et al'' conducted experiments on 20 indole-negative strains previously grouped with ''P.vulgaris'' and demonstrated the existence of three ''P. vulgaris'' biogroups. ''P. vulgaris'' biogroup 1, or indole-negative ''P. vulgaris'', was distinguished as a new species within the ''Proteus'' genus in 1982.〔 The new species was named ''Proteus penneri'' in honor of John Penner, a Canadian microbiologist.〔
