Biochemical Test of Proteus mirabilis. Notice the background of the slide is colored so that you can see the protective slime coating secreted by many bacteria. Procedure of Acid-Fast Stain Prepare bacterial smear on clean and grease free slide, using sterile technique. 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. Thanks you sir. Allow smear to air dry and then heat fix. Pseudomonas aeruginosa (1000X total magnification) 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 grouped with the Morganellaceae and is an opportunistic pathogen of humans. (23) Suthar S., Chhimpa V., Singh S. 2009. spp, Salmonella .

Xkx BALF+ =@c9( {F17@ ;( Positive (+ve) When the smear is stained with carbol fuchsin, it solubilizes the lipoidal material present in the Mycobacterial cell wall but by the application of heat, carbol fuchsin further penetrates through lipoidal wall and enters into cytoplasm. In Nigeria, P. vulgaris was found to be the most active strain degrading crude oil compared to other species. Several species of Mycobacterium and Nocardia are pathogenic for animals and humans. Journal of Pharmacology and Pharmacotherapeutics. First off, a streak plate must be done on a nutrient agar plate. 2(4): 339-343. Acid-fast mycobacteria contain mycolic acid in their outer membrane, making the cells waxy and resistant to staining with aqueous based stains such as the Gram stain. Thank you. Albert stain for confirmation to show green tail and reddish metachromatic granules. Bubbling in The following test below shows my journey towards finding my unknown. Learn how your comment data is processed. Hello, Thanks for the suggestion. Urease production leads to precipitation of organic and inorganic compounds, which leads to struvite stone formation. P. vulgaris may also have positive applications, such as biofuel production (12), aromatic contribution to cheese ripening (13), and plant growth promotion (14), but further research is needed to prove the effectiveness and validity of these applications. Gram-negative bacilli are typically distinguished by size, shape, motility, and oxygen growth categories.
