P. vulgaris has been reported to cause urinary tract infections, wound infections, burn infections, bloodstream infections, and respiratory tract infections (1). Bacteria in Natural Environments. I wanted to know what are the confirmation test for Mycobacterium smegmatis after acid-fast stain? 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. What to expect from early intervention orthodontics? I had my times of mistakes trying to find out these bacteria from the rest but I stuck to the fundamental basics of the lab manual and believed in myself. For this test, I was able to finalize the result of my unknown to be Proteus vulgaris. Biochemical Test and Identification of Citrobacter freundii. This test allows bacterium that can use citrate as its sole carbon source. A secondary stain, methylene blue, is then applied to the cells. Proteus vulgaris : Streptococcus pyogenes Proteus mirabilis : Streptococcus faecalis Klebsiella pneumoniae : Streptococcus agalactae Serratia marcescens . E. coli produces an acid butt, an acid or alkaline slant, and no H2S, but does produce gas. This eliminated two bacterium: Enterobacter aerogenes and Pseudomonas aeruginosa, leaving E. coli, P. vulgaris and K. pneumonia. We are here to help you achieve your educational goals! Gently heats the slide till fumes appear & keep the smear moisten with dye. Albert stain for confirmation to show green tail and reddish metachromatic granules. Under a microscope, if the gram stain is purple, the bacterium is gram positive, if the stain is red, it is gram negative.

Spirillum volutans, a helical cell, moves by polar amphitrichous flagella; notice flagella at each end of the bacterial cell. The heating process allows the primary stain, cabolfuchsin to penetrate further especially when the lipoidol membrane is large which otherwise could not permit penetration. (17) Senior B.W., Larsson P. 1983. (11) Lee, K., Park S. J., Choi S. J., Park J. Y. Conversely, the the outer membrane of Gram negative bacteria is degraded and the thinner peptidoglycan layer of Gram negative cells is unable to retain the crystal violet-iodine complex and the color is lost. Proteus mirabilis is a type of bacteria that can cause various infections in the body.

Specifically, it has been reported that P. vulgaris was used in an electrochemical chip to detect urea levels in synthetic urine (8). In one case study, P. vulgaris caused bacteremia, the presence of bacteria in the blood, and brain abscesses with a suspected point of entrance in the digestive tract (9). Even though there is a standard routine for Gram staining, there are some variables that can affect this stain, e.g., the age of the culture, the amount of decolourizer used, the time of decolorization, the type of organism (acid-fast bacteria and spores do not stain well . This complex is a larger molecule than the original crystal violet stain and iodine and is insoluble in water. Future. 2:3. It is referenced in the Analytical Profile Index using the nine-digit code: 047602157. P. vulgaris produces an acid butt, an acid or alkaline slant, H2S, and gas.

There will be no differentiate bw afb and non-afb, bz, there is no enough penetration of carbol fuschin to the cytoplasm thats why decolorizer flushes off the fuschin, and there will be counterstaining of methylene blue to both type of bacteria if that is AFB or non-AFB. Help. Acid reflux from the stomach causes metaplasia to nonciliated, mucin-producing columnar cells (better able to handle the stress of acid, .2). (19) Kim N., Choi Y., Jung S., Kim S. 2000. I need clarification on the acid fast stain. There are two methods of acid-fast staining. These Gram-resistant, slightly curved bacilli are the causative agents of tuberculosis. The acid-fast stain uses three different reagents: carbol fuchsin, acid-alcohol, and methylene blue. It is the differential staining techniques which was first developed by Ziehl and later on modified by Neelsen.
