What are the biochemical test and identification of Proteus vulgaris? (14) Bhattacharyya, D., Garladinne, M., Lee, Y. H. 2014. Acid-fast organisms are characterized by wax-like, nearly impermeable cell walls; they contain mycolic acid and large amounts of fatty acids, waxes, and complex lipids. Because of its unique cell wall, when it is stained by the acid-fast procedure, it will resist decolorization with acid-alcohol and stain red, the color of the initial stain, carbol fuchsin. This eliminated three other bacterium: Klebsiella pneumonia, Enterobacter aerogenes, and Pseudomonas aeruginosa, leaving E. coli and P. vulgaris. Leave the slide on the water bath for 3 to 5 minutes. Rods are called Bacilli (Bacillus singular), Please how is the biochemical composition of acid fat bacteria is used in the identification and diagnosis of a named AFB. Nutrient agar is always a safe choice. The shaped of this bacterium was rounded and ball shaped. If indole positve_ P.vllulgaris if negative P.mirabilis. More often, women present with UTI, flank pain, or hematuria, and are found to have a persistently alkaline urine pH (>7.0). Both of these requirements can occur only when urine is infected with a urease-producing organism such as Proteus. Biogroup one was indole negative and represented a new species, P. penneri, while biogroups two and three remained together as P. vulgaris. Because their cell wall (thin cell wall). %%EOF C85250. Way to go You are DONE! Save my name and email in this browser for the next time I comment. Vibrio natriegens is not acid fast, it is Gram negative. Production and partial characterization of biosurfactant produced by crude oil degrading bacteria. All members of the genus Proteus are known to be saprophytes, an organism that resides in dead or decaying organic matter, mainly in fecal matter and intestinal tracts of humans and animals (1, 3). Proteus species are part of the Enterobacteriaceae family of gram-negative bacilli. Mycolic acid-produces the acid fast stain.

Apart from the pigmented colonies, Pseudomonas aeruginosa grown in media is also characterized by grape-like smell. The chemical structure of the sugar part of the lipopolysaccharide may play a role in enhancing pathogenicity (16). (adsbygoogle = window.adsbygoogle || []).push({}); Biotechnology and Bioengineering. OK This mixed smear shows typical bacilli, yeast, and human blood cells. When comparing Genus Proteus, a key tool to decipher P. vulgaris from other species in the genus is that P. vulgaris is indole-positive using an spot indole test using dimethylaminocinnamaldehyde reagent (20) . Proteus mirabilis is a type of bacteria that can cause various infections in the body. First off, a streak plate must be done on a nutrient agar plate. (17) Senior B.W., Larsson P. 1983. Proteus vulgaris and Proteus mirabilis represent 18.7% (9 isolates), and 81.25% (39 isolates) respectively. The ammonia/ammonium buffer pair has a pK of 9.0, resulting in the combination of highly alkaline, ammonia-rich urine. TMCC provides a wealth of information and resources. P. vulgaris is also found on the surface of ripened cheese, and produces high concentrations of flavor compounds from amino acid degradation during the ripening process (13). Commonly the NAM & MacConkey Agar medium is used for the cultivation of Proteus Vulgaris in Laboratory. Discussion / Conclusion. The oxidase test was performed on unknown #122 gram positive, showed to be positive. In Liquid culture media like Trypticase soy broth or Nutrient broth & Peptone Water, the growth of the bacterium occurs as a uniform turbidity in the broth medium with a powdery deposit and Ammoniacal smell which is further analyzed for the morphology (under the microscope), gram reaction, biochemical tests, and Proteus Vulgaris specific tests. He attended St. Xaviers College, Maitighar, Kathmandu, Nepal, to complete his Master of Science in Microbiology. Finally, blood agar is always really cool for p. mirabilis, because the organism has a tendency to swarm across the agar (because of its high motility), so thats cool to see. Please I thought the counter stain for acid fast was malachite green? Then the smear is stained with counterstain, methylene blue. (20) Mohr OHara, C., Brenner F.W., Miller J.M. What grows Endo Agar? The non-acid fast organism lack the lipoidal material in their cell wall due to which they are easily decolorized, leaving the cells colorless. Heating simple helps in the enhancement on the penetration of the carbol fuchsin(primary dye) into the cytoplasm. 2. You only need to highlight how you prepare the smear. H X L (Felix) ATCC 6896; H X L (FELIX) Proteus vulgaris RECEIVED FROM FELIX A LISTER INSTITUTE LONDON The National Collection of Type Cultures comprises over 5000 bacterial cultures, over 100 mycoplasmas and more than 500 plasmids, host strains, bacteriophages and transposons.
