P. vulgaris does digest casein. When placed on a casein agar plate, which is opaque, and incubated P. vulgaris will leave a "clear zone" where the casein is being broken down. This proves that protein hydrolysis occurs.

Yes, Klebsiella pneumoniae has the ability to digest casein. This bacterium produces protease enzymes that can break down casein protein into smaller peptides and amino acids, which can then be utilized as a nutrient source for the bacteria.
Yes, Klebsiella pneumoniae is usually positive for nitrate testing. It typically reduces nitrate to nitrite which can be detected using a reagent.
Klebsiella pneumoniae is not typically considered highly contagious, but it can be spread through contact with contaminated surfaces or medical equipment. Good hygiene practices, such as handwashing and proper cleaning of medical facilities, can help prevent its transmission.
Klebsiella pneumoniae can be fatal, especially in vulnerable populations such as the elderly or those with weakened immune systems. It can cause severe infections like pneumonia, bloodstream infections, and urinary tract infections that may lead to serious complications or even death if not properly treated. Prompt and appropriate medical intervention is crucial in managing Klebsiella pneumoniae infections.
Klebsiella pneumoniae is typically citrate negative, meaning it does not utilize citrate as a carbon source in the citrate utilization test. This bacterium lacks the enzyme citrate permease needed for citrate utilization.
Adonitol fermentation test results for Klebsiella pneumoniae would typically show a positive result, meaning the organism is able to ferment adonitol and produce acid. This can be observed by a color change in the growth medium from red to yellow.
