Please I thought the counter stain for acid fast was malachite green? I am a Medical Lab Tech, a Web Developer and Bibliophiliac. This is a very difficult and time-consuming stain because the flagella are very thin and fragile. The ammonia/ammonium buffer pair has a pK of 9.0, resulting in the combination of highly alkaline, ammonia-rich urine. Thus Ziehl-Neelsen staining techniques was developed. 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. Then the slide is kept undisturbed for 5 minutes and allows it to cool. i think there has been a mistake Positive (+ve) Then the smear is stained with counterstain, methylene blue. A key characteristic of genus Proteus is swarming ability, and a simple Dienes test is used to differentiate between strains (17). Domain; Phylum; Class; Order; Family; Genus A negative stain is used for the identification of bacterial cell organization, and the presence of bacterial flagella.

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). (20) Mohr OHara, C., Brenner F.W., Miller J.M. 4. P. vulgaris is relevant in many fields of research, due to its pathogenic capabilities, as well as its capacity for antibiotic resistance (4, 5, 6). In this unit you will be observing endospores, flagella, capsules, bacteria that are identified via a staining technique called "Acid Fast", and the eukaryotic yeast Candida albicans Some of these features help the microbes succeed in their environment and aid in species identification. The above discussion had been very much educative and it reminded me of my days in the university especially during my industrial training at Adamawa Hospital Yola, Nigeria. Usually, it produces non-hemolytic growth on Blood agar plate but some of the strains are -Hemolytic. Judicial Commission 1999. Antibacterial agents and heavy metal resistance in Gram-negative bacteria isolated from seawater, shrimp and sediment in Iskenderun Bay, Turkey. You only need to highlight how you prepare the smear.

Then the smear is decolorized with decolorizing agent (3% HCL in 95% alcohol) but the acid fast cells are resistant due to the presence of large amount of lipoidal material in their cell wall which prevents the penetration of decolorizing solution. (7) Hawkey, P. M., Hawkey, J. L., Penner, A. H., Linton, C. A., Hawkey, L. J.. Learn how your comment data is processed. Proteus vulgaris Introduction Proteus vulgaris is a gram-negative bacterium. After the addition the nitrate reagents the liquid turned from yellow to red, indicating a positive result. A secondary stain, methylene blue, is then applied to the cells.

Because of its special form of the cell wall as being an acid fast bacterium, all the initial dyes are retained instead of washed away. Because of this feature, this stain is extremely helpful in identification in diseases caused by acid-fast bacteria, particularly tuberculosis and leprosy. endstream endobj 21 0 obj <>stream Neelsen in 1883 used Ziehls carbol-fuchsin and heat then decolorized with an acid alcohol, and counter stained with methylene blue. the causative agent of T.B Mycobacterium, since its staining meth is for differenciation, and so, is it a gram pos or neg? When inoculated in a gelatin stab test, P. vulgaris is capable of hydrolysis of gelatin.[2]. Lab results indicated that the rapid test for infectious mononucleosis antibodies was negative. Hello, Thanks for the suggestion. Thanks you sir. The main aim of this staining is to differentiate bacteria into acid fast group and non-acid fast groups. Then obviously the colour of your background will depend on the colour of the stain used. View Untitled document.edited (2).docx from BIOL 2320 at Houston Community College. Medical Subject Headings (MeSH) 1.2.2 NCI Thesaurus Code. Clinical Microbiology Reviews. Am pascal studying medical lab in technical university Kumasi Ghana.my question is both carbol fuchsin and methylene blue are basic dyes, so what will happen if we use methylene blue as our primary stain? LYSINE 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. This makes it resist decolorizer and takes the color of counterstain( safranin or neutral red), Note THIS , Gram negative bacteria is toxic to human and it is refers to as endotoxins. Omitting the step could lead to false results since the cabolfuchsin might be de-colorized leading to false negative results. Heat the slide for 5 minutes on a very low flame (temperature may go up to 60C. 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). Your email address will not be published. Ziehl-Neelsen stain is mainly used for staining acid-fast bacteria such as Mycobacterium spp, and Nocardia spp. Organisms cultivated on blood agar may experience nutrient deprivation, resulting in a lower lipid content in the outer membrane resulting in poor staining. Prepare bacterial smear on clean and grease free slide, using sterile technique. Try these reference materials Microbiology by Monica Chessebrough volume 1and 2. Size The size of Proteus Vulgaris is about 13 m 0.5 m (micrometer). Biotechnology and Bioengineering.
