penner i was isolated from pus from pressure sore of a patient of road traffic accident. Extended spectrum beta lactamase (ESBL) positive and multidrug-resistant (MDR) P. penneri is naturally resistant to ampicillin, narrow spectrum cephalosporins, and cefuroxime by the production of beta lactamase commonly known as cefuroximase. The clinical significance of Proteus penneri, described in 1982 as a new species and previously known as Proteus vulgaris indole negative, is poorly documented.

Correct and rapid isolation and identification of such resistant pathogen are important as they are significant nosocomial threat. penneri isolated from pus from pressure sore of a patient of road traffic accident. We report a case of extended spectrum beta lactamase producing and multidrug-resistant P. Indole negative Proteus species are invariably incorrectly identified as Proteus mirabilis, often missing out isolates of Proteus penneri.
