Positive
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.
butt colour and reaction - yellow slant colour and reaction - yellow carbohydrate fermented - glucose only H2S production :- blackening- NO H2S - (-) negative
The IMViC test results that would indicate the presence of fecal coliforms are negative for indole production, positive for methyl red test, negative for Voges-Proskauer test, and positive for citrate utilization.
The Api 20E system can identify E. coli based on the biochemical reactions it produces. Results may include positive reactions for indole production, glucose fermentation, and citrate utilization, among others. It is important to interpret the full profile of reactions to accurately identify E. coli.
A light blue top tube containing 3.2% sodium citrate is typically used to collect blood for PT/INR testing. The sodium citrate acts as an anticoagulant to prevent blood clotting and ensures accurate results. It is important to follow the exact collection procedures specified by the laboratory to avoid any potential issues with the test results.

Negative Negative Negative Negative
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.
The test indicates if an organism utilizes Citrate as it's only source of Carbon. Positive results will show growth on slant as well as changing the medium from green to blue (ph indicator)
butt colour and reaction - yellow slant colour and reaction - yellow carbohydrate fermented - glucose only H2S production :- blackening- NO H2S - (-) negative
The TSI test for Klebsiella typically shows alkaline slant/acid butt results, meaning the organism ferments glucose but not lactose or sucrose. Klebsiella is usually a glucose fermenter and produces gas, causing the butt to be lifted.
The IMViC test results that would indicate the presence of fecal coliforms are negative for indole production, positive for methyl red test, negative for Voges-Proskauer test, and positive for citrate utilization.
Many bacteria that are able to metabolize citrate do not produce a positive result on citrate utilization tests because they usually require specific conditions or mutations to express the necessary citrate transporter genes. In the absence of these conditions or mutations, the bacteria cannot transport citrate into the cell for metabolism, resulting in a negative test result.
It results in tissue death which is what necrosis means.
The Api 20E system can identify E. coli based on the biochemical reactions it produces. Results may include positive reactions for indole production, glucose fermentation, and citrate utilization, among others. It is important to interpret the full profile of reactions to accurately identify E. coli.
No, Staphylococcus epidermidis is typically citrate negative, meaning it cannot utilize citrate as a carbon source for growth. This characteristic can be used in biochemical tests to help differentiate it from other bacteria.
