Is serratia marcescens acid-fast?
Serratia marcesens is an acid fast negative bacillus. It appears blue under the microscope.
What could affect MMPI results?
Cultural and language differences in the test subject may affect test performance and may result in inaccurate MMPI results.
What are the test results of adonitol for klebsiella pneumoniae?
positive
What are the results for klebsiella pneumoniae in the citrate utilization test?
Positive
Does Thyroid blood tests shows HIV in the test results?
no
What test will show you the difference between Proteus vulgaris and Morganella morganii?
alpha-glucosidase test: using 5-bromo-4-chloro-3-indolyl-alpha-D-glucopyranoside (included in chromogenic media), but not using alpha-methyl-glucoside fermentation. Cronobacter (E. sakazakii) are positive for this test and E. aerogenes are negative.
Does Enterobacter aerogenes produce gas in the Kligler Iron Agar test?
Yes. Enterobacter aerogenes ferments lactose and glucose as well as producing gas. It does not produce H2S. Occasionally the slant may revert to an alkaline reaction even though lactose has been fermented. Another lactose test should be formed, such as the reaction on MacConkey agar
What is the gram stain of enterobacter aerogenes?
Enterobacter aerogenes is a Gram negative rod-shaped bacterium in the same family as Esherichia coli. It can grow on many of the same selective media as Esherichia coli, including: MacConkey Agar, EMB agar and Lauryl-Tryptose broth. E. aerogenes ferments lactose, producing acid and gas like Esherichia coli and is classified as an example of coliform bacteria. There are several significant differrences between E. aerogenes and E. coli: 1) Most strains of E.coli are able to grow and produce acid from lactose in a medium such as lauryl tryptose broth or brilliant green bile broth at 44.5 degrees C. while most strains of E. aerogenes do not grow well at that temperature, E. aerogenes grows better at temperatures betwee 34 - 40 degrees C. 2) E. aerogenes carries out 2,3-butanediol fermentation and thus give a positive test in the Voges-Proskauer test while E. coli is negative. 3) E. coli is positive in the methyl red test while E. aerogenes is usually, but not always, negative (this is not the best test to rely on). 4) E.coli is positive for the indole test while E. aerogenes is negative, this is a very reliable test. 5) E. aerogenes can grow on Simmon's citrate agar while E. coli does not. You can distinguish between E. aerogenes and bacteria in the Proteus and Salmonella genera by using the hydrogen sulfide test, using either Kligler's iron agar or triple sugar iron agar. Most Proteus and Salmonella strains produce hydrogen sulfide and make a black precipitate but E. aerogenes does not. There are a lot of similarities between Enterobacter aerogenes and Klebsiella pneumonia. The urease test is one of the few tests that distinguishes E. aerogenes from K. pneumonia.

Klebsiella is positive for urease production while Enterobacter is negative.
Which organisms does Voges-Proskauer test for?
VP + is typical for Enterobacter, while f.e. E. coli is VP-. It means that Enterobacter is able to ferment butanediol, while E. coli isn't
What is a Triple sugar iron agar test?
TSI test used to differentiate the enterobacteriaceae family members like e.coli and enterobacter and pseudomonas
In the carbohydrate fermentation test you found that both E. coli and E aerogenes produced the end products acid and gas Account for the fact that E. coli is methyl red positive and E aerogenes is?
E. aerogenes is Methyl Red negative due to the fact that it enzymatically converts these acidic end products into a more basic end product through the use of Acetylmethylcarbinol.
Could an organism be both MR and V-P positive?
An organism can not test positive for both an MR test and a V - P test. The MR test is an abbreviation for Methyl Red and it tests for E coli The V - P is an abbreviation for Vogue Proskauer and it tests for enterobacter and klebsiella.
Is serratia marcescens acid-fast?
Serratia marcesens is an acid fast negative bacillus. It appears blue under the microscope.
How can I get the results of my Ultrasound Technician test?
The results of your certification test are usually mailed to you with a month or two of taking the test. If you don't receive your results you should contact the company that administered the test.
How IMViC tests differentiate Escherichia coli from Enterobacter aerogenes?
Indol Test ( Kovac's Reagent): E.a. = negative = yellow/gold ring at meniscus; as for E.c. = positive = red ring at meniscus (immediate change). Methyl Red Test (Methyl Red Reagent): E.a. = negative = yellow = pH > 7.0; as for E.c. = red color = pH < 5 (immediate change). Vogues-Proskauer Test (Napthol + KOH Reagent): E.a. = positive = reddish color (not immediate change); as for E.c. = negative = brown/yellow (straw color). Citrate (Bromothymol Blue Reagent - alkaline pH): E.a. = positive = blue color + growth; as for E.c. = negative = green color.
