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. 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). 1. Proteus organisms are implicated as serious causes of infections in humans, along with Escherichia, Klebsiella, Enterobacter, and Serratia species.

You will do some of these staining procedures in the next lab (acid-fast staining and endospore staining). Properties ( Proteus mirabilis ) Capsule. Gram Staining Reaction - Proteus Vulgaris is a Gram -ve (Negative) bacterium. Because of its unique cell wall, when it is stained by the acid-fast procedure, it will resist decolorization with acid-alcohol and stain red, the color of the initial stain, carbol fuchsin. (1) Drzewiecka D. 2016. In calf bedding samples contaminated with feces, P. vulgaris was the first of its genus to be identified, such that food animals may be a source of P. vulgaris in the human gut (7). I think I will give to you answer in convincing way. This is because it retains the primary color cabolfuchsin due to its large lipoidol membrane which does not allow decolorization by either the acid or alcohol hence acid-alcohol fast. al. Acid Fast Bacteria. According to laboratory fermentation tests, P. vulgaris ferments glucose and amygdalin, but does not ferment mannitol or lactose. This test allows bacterium that can use citrate as its sole carbon source. The first procedure that was done was the gram stain. Decolorization Solution: Add 30 mL hydrochloric acid to 1 L of 95% denatured alcohol. Due to a special wax in their cell membrane, these organisms do not readily take up dye from a typical gram stain. gram-positive bacilli.

After 48 hours of incubation, nutrient agar plate showed two distinct colonies. Non-acid fast: Blue color;In addition, background material should stain blue. Many wild and domestic animals can be hosts of P. vulgaris bacteria, where they commonly play the role of a parasite (1). A secondary stain, methylene blue, is then applied to the cells. 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. Gram stain.

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. These are organisms that resist decolourization by 3%Acid alcohol stain after hearing the strong carbolfuchsin solution during staining. Ziehl-Neelsen Stain name is from the surnames of German doctors, bacteriologist Franz Ziehl(1859-1926), and pathologist Friedrich Neelsen (1854-1898). vulgaris can survive alkaline pH as well as acidic pH ranging from 4.0 11.0 and the maximum growth of the organism is observed at 6.0 i.e. HNO.

Hello, Thanks for the suggestion. Once the two colonies were found, they were isolated on separate agars for growth. P. vulgaris present in water or soil conditions usually indicates fecal pollution, which poses a dangerous health risk when consumed in the form of food or water, such as the occurrence of P. vulgaris in raw shellfish (21). It can be found in soil, water, and fecal matter. Remove the filter paper and rinse the slide with water until the solution runs clear. Biodiesel synthesis assisted by ultrasonication using engineered thermo-stable Proteus vulgaris lipase. After the test was done, the result positive after the addition of the reagent. 0 But you mean no need of malachites green when methylene blue is available ??? P. vulgaris is also known to cause numerous types of nosocomial infections, including those of the urinary tract, burns, and other exposed wounds, and can be associated with various types of brain abscesses (9, 10, 11).

You only need to highlight how you prepare the smear. MacConkey is usually fairly decent, especially if you want to test the lactose fermentation thing. The Swarming of Proteus vulgaris is best observed in Nutrient Agar medium, covering the whole plate. After another 48 hours, there were two different unknown bacterium growing on the two different nutrient agar plates used. Enterobacterales (of which Proteus is a member) and Pseudomonas species are the micro-organisms most commonly responsible for Gram-negative bacteremia and sepsis. (7) Hawkey, P. M., Hawkey, J.

Notice the background of the slide is colored so that you can see the protective slime coating secreted by many bacteria. All combine for a Biocode ID of 31406, (Biocode ID 31402, 31404, 31407 all resulting in P. vulgaris with asymptomatic results) for use in the Interpretation Guide/Computer Coding and Identification System. Your explanation of the principle and procedure for Acid fast staining were basically correct. It has been observed in the digestive tracts of various livestock, including cattle, bovines, and carp, making the bacterium a danger to humans by means of food contamination (5, 7, 8). 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.

Some of these organisms have distinct qualities that set them apart from one another, such as the exposure to certain environments. Lastly casein test was performed, test showed positive result for the break down of casein. Nature. Vulgaris is a flagellated bacterium with a Peritrichous flagella arrangement i.e. A recent study found that using copper oxide and silver nanoparticles is effective at inhibiting the growth of P. vulgaris through the release of ions and free radicals that disrupt its enzymatic and DNA activity (24). Albert stain for confirmation to show green tail and reddish metachromatic granules. Please what is the function of counter stain in Ziehl Neelsen staining, because I read the function differs from that of gram staining.
