The following test below shows my journey towards finding my unknown. Being a non-fermentor, the bacterium is also associated with acid production in culture rather than gases which are commonly associated with fermenting bacteria. It is because it will retain the primary stain, which is CarbolFuschin stain, with large lipid content in its wall preventing anything to penetrate through. 1937.

Decolorization Solution: Add 30 mL hydrochloric acid to 1 L of 95% denatured alcohol. When P. vulgaris is tested using the API 20E identification system[1] it produces positive results for sulfur reduction, urease production, tryptophan deaminase production, indole production, sometimes positive gelatinase activity, and saccharose fermentation, and negative results for the remainder of the tests on the testing strip. In Blood Agar medium, the Proteus Vulgaris exhibits the swarming and the growth occurs in the whole media plate. The excess stain is removed with treatment by acid alcohol (ethanol and hydrochloric acid). The presence of mycolic acid in their cell walls . Nitrate test was performed, test showed to be positive after the reagents were added.

Flagella Pr. Preparation of Smears for Staining 4.6.1.3. Fix the smear onto the slide by passing over the flame of Spirit lamp or Bunsen burner. The primary objective was to isolate two different colonies within the test tube. Commonly the NAM & MacConkey Agar medium is used for the cultivation of Proteus Vulgaris in Laboratory. Serological classification and epitope specificity of Proteus vulgaris TG 251 from Proteus serogroup O65. The first procedure that was done was the gram stain. Usually, it produces non-hemolytic growth on Blood agar plate but some of the strains are -Hemolytic. Biogroup one was indole negative and represented a new species, P. penneri, while biogroups two and three remained together as P. vulgaris. Treponema pallidum is the causative agent of syphilis.

Nevertheless, different Gram stain results are not necessarily incorrect. Dissolve 3 g nethylene blue in 1 L distilled water. P. vulgaris can also test urease negative in solid media (such as in Enterotube), but will be urease positive in liquid media. P. vulgaris is a rod-shaped, Gram negative bacterium between 1-3 microns in size, and is extremely motile, utilizing peritrichous flagella as its source of motility (2). Cool and mix well before using. Acid reflux from the stomach causes metaplasia to nonciliated, mucin-producing columnar cells (better able to handle the stress of acid, .2). In your procedure however, the preparation of the smear needs not be sterile but aseptically done to prevent unwanted materials/organisms on your slide and assuring that only the specimen you intend to examine is on your slide.
