No.

Disagree. You'll find a positive sucrose fermentation test for P. vulgaris at MicrobeLibrary.org. The site is an affiliate of the American Society of Microbiology, so I'm guessing it's a safe bet.
Proteus mirabilis and Proteus vulgaris can be differentiated based on their biochemical characteristics. One key distinction is that P. mirabilis is typically urease-positive and does not produce indole, while P. vulgaris is urease-positive and does produce indole. Additionally, P. vulgaris can be further differentiated from P. mirabilis by its motility and the ability to ferment certain carbohydrates. Laboratory tests, such as the urease test and indole test, can help confirm the identification of each species.
Proteus mirabilis is positive for the urea test, meaning it can hydrolyze urea, producing ammonia and raising the pH of the medium, causing a color change. This is due to the presence of the enzyme urease in Proteus mirabilis.
Proteus mirabilis is catalase-positive, meaning it produces the enzyme catalase, which breaks down hydrogen peroxide into water and oxygen. When subjected to a catalase test, the addition of hydrogen peroxide to a culture of Proteus mirabilis will result in the production of bubbles, indicating a positive reaction. This characteristic helps differentiate Proteus mirabilis from other similar bacteria that may be catalase-negative.
Yes it does
Proteus species, such as Proteus mirabilis and Proteus vulgaris, typically exhibit two key colony characteristics: they often produce a characteristic swarming motility on solid media, leading to a thick, spreading growth pattern that can resemble a circular or concentric pattern. Additionally, their colonies are usually non-lactose fermenting, appearing as pale or colorless on MacConkey agar, which helps in distinguishing them from lactose-fermenting bacteria.
Yes, P. vulgaris is a lactose non-fermenter. It does not possess the enzyme beta-galactosidase needed to ferment lactose into glucose and galactose. Instead, it typically ferments sugars like glucose and sucrose.
Proteus mirabilis is not a coccobacillus. Rather, it is rod shaped. Proteus mirabilis is also Gram-negative, facultatively anaerobic, and motile.
Yes, Proteus vulgaris is considered a coliform bacteria because it is a Gram-negative, facultative anaerobe that can ferment lactose. Coliform bacteria are a group of bacteria used as indicators of water quality and fecal contamination.
In very rare occasion proteus mirabilis can get into the bloodstream and migrate to the lungs and attach itself there. However that is very rare. Proteus mirabilis most commonly affects the urinary tract.
Yes, Proteus mirabilis is a flagellated bacterium and can move through its environment by utilizing its flagella.
No
Proteus mirabilis is positive for the urea test, meaning it can hydrolyze urea, producing ammonia and raising the pH of the medium, causing a color change. This is due to the presence of the enzyme urease in Proteus mirabilis.
Proteus mirabilis is from the Enterobacteriaceae family, is Gram-negative, and rod shaped. It is known to cause urinary tract infections and form stones.
Yes it does
Proteus mirabilis bacteria are rod-shaped (bacillus) and have a single flagellum at one end that assists in movement. They are known for their swarming motility on agar surfaces.
Clindamycin is generally not effective against Proteus mirabilis, as this bacterium is often resistant to this antibiotic. Proteus mirabilis is typically treated with other classes of antibiotics, such as penicillins or cephalosporins, depending on susceptibility patterns. It's important to consult susceptibility testing to determine the most effective treatment for infections caused by this organism.
Proteus is phenylalanine deaminase, urease and indole positive Salmonella negative. Proteus swarm on nonselective media, Salmonella does not.
