The authors want to present this case with the objectives to highlight the conventional methods employed for identification of P. penneri 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. Extended spectrum beta lactamase producing Proteus penneri: A rare missed pathogen?.

Keywords: Extended spectrum beta lactamase producing, multidrug-resistant, Proteus penneri How to cite this article: Pandey A, Verma H, Asthana AK, Madan M. 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.
The CCIS code will still identify Proteus vulgaris with a negative urease test.Extended spectrum beta lactamase producing Proteus penneri: A rare missed pathogen?Īnita Pandey, Himani Verma, Ashish K Asthana, Molly Madanĭepartment of Microbiology, Subharti Medical College, Swami Vivekanand Subharti University, Meerut, Uttar Pradesh, IndiaĬlick here for correspondence address and email Date of Web Publication Note that Proteus vulgaris can also test Urease negative in solid media (such as in Enterotube), but will be Urease positive in liquid media. All combine for a "Biocode ID of 31407" for use in the Interpretation Guide/Computer Coding and Identification System (CCIS).
Proteus vulgaris tested positive for Citrate. The Phenylalanine test was positive as was the Harnstoff Urea test. Negative for Arabinose, Sorbitol and Dulcitol. Positive for Hydrogen sulfide production and positive for Indole production. The Becton/Dickinson BBL Enterotube II system for identification of members of the family Enterobacteriaceae inoculated with Proteus vulgaris may yield the following results: Positive for Glucose fermentation (with gas production). The optimal growing conditions of this organism is in a facultative anaerobic environment with an average temperature of about 37 degrees Celsius. It is referenced in the Analytical Profile Index using the nine-digit code: 047602157 vulgaris is tested using the API 20E Identification System test strip for enterobacteriaceae (made by BIOMERIEUX), it is discovered that it provides a positive result for: sulfur reduction, urease production, tryptophan deaminase production, indole production, sometimes positive gelatinase activity and saccharose fermentation, and provides a negative result for the remainder of the tests on the testing strip. vulgaris also tests positive for the methyl red (mixed acid fermentation) test and is also an extremely motile organism. vulgaris ferments glucose and amygdalin, but does not ferment mannitol or lactose. According to laboratory conducted fermentation tests, P.
