A basic nutrient agar plate was the medium chosen for isolation and the isolation streak method described on page 10 in the lab manual was used in an effort to separate the unknowns. Proteus bacilli are widely distributed in nature as saprophytes, being found in decomposing animal matter, sewage, manure soil, the mammalian intestine, and human and animal feces. On my nutrient agar, MacConckey's and blood agar plates, they were all round, white and slightly dome-shaped (raised). In some colonies, a metallic green color is given off by the specimen. It was named Proteus after an elusive character in Homer's Odyssey who was able to escape capture by changing its form. Print, UNKNOWN LAB REPORT The first procedure completed was the growth of two isolation streaks on nutrient agar plates from mixed culture 102. This exercise will help you identify the cultural characteristics of a bacterium on an agar plate - called colony morphology. No Pigmentations. Nitrate I grew Proteus mirabilis on it, and interestingly, it still swarms on the agar, although slower if compared to its growth on a nutrient agar.

The characteristics of a colony (shape, size, pigmentation, etc.) Infections may also be contacted through transmission of the bacteria from other patients or from a common reservoir. the results were correct, P. vulgaris grew in clear colonies, fermenting xylose but not producing Proteus mirabilis, P. vulgaris are widely recognised as human pathogens. Learn vocabulary, terms, and more with flashcards, games, and other study tools. A Bacillus subtilis strain showed a variety of colony growth patterns on agar plates. coli Isolates The colony appeared as green with black metallic sheen of the stool samples which were cultured on Eosin Methylene Blue agar, and again were picked and sub cultured on fresh EMB agar plates to obtain presumptive E. Typical colony morphology of our strains of Enterobacteriaceae and Pseudomonas aeruginosa on MacConkey agar is as follows: 1. The Proteus group of bacteria also frequently gives rise to bacteraemia. Results Flow Chart 4: careful order of tests was followed that led to Proteus vulgaris as the unknown from the alternate the common Proteus vulgaris, but the one of clinical relevance is called mirabilis, from the Latin meaning wonderful or surprising. Antimicrobials that are most effective in inhibiting P. Mosby’s Medical Dictionary, 8th edition. The medium is made up of basic nutrient that is essential for a wide variety of organism, which makes it a general media that can be used for various purposes. Recognizing different bacterial growth morphologies on agar plates is a useful and often crucial step in the identification process.
