What test will differentiate between Proteus vulgaris and Pseudomonas aeruginosa?
This is a bit tricky. Both Proteus vulgaris and Pseudomonas aeruginosa are Gram-negative and rod-shaped. According to Bergey's Manual of Systematic Bacteriology, Proteus vulgaris tests positive for sulfur reduction, urease production, tryptophan deaminase production, and indole production. Pseudomonas aeruginosa reduces sulfur and nitrate, and has a characteristic green color. The API 20E Identification System is a test strip that can be used to identify Proteus vulgaris versus other bacteria.An even easier way to test this is the gelatinase test.Or, slant the bacteria on a Triple Sugar Iron slant or place them in a SIM agar deep. P. vulgaris tests positive for Hydrogen Sulfide production, changing the media to a black color around the organism, while P. aeruginosa does not produce Hydrogen Sulfide.
How can you differentiate the pigment of p aeruginosa on pseudomonas agar P from the pigment of E coli on MacConkey agar without referring to the colors?
It's not easy to differentiate the pigment of p aeruginosa on pseudomonas agar P from the pigment of E. coli on MacConkey agar without referring to the colors, but it can be done based on the structure of the p aeruginosa.
Will p. aeruginosa grow on a blood agar media?
no
Is a protons charge negative or positive?
A proton is positively charged. Think of it this way: P for proton, p for positive.
What is the morphological category of the pseudomonas bacteria?
Members of the genus Pseudomonas display the following defining characteristics: • Rod shaped •Gram-negative • One or more polar flagella, providing motility • Aerobic, although some species have been found to be facultative anaerobes (e.g. P. aeruginosa) •Non–spore forming • Positive catalase test
What is the difference between A. faecalis and P. aeruginosa?
P. aeruginosa is positive for nitrate reduction where as A. faecalis is negative.
Is proteus vulgaris arabinose negative?
No. The arabinose medium should stay red if incubated with P. aeruginosa, not turn yellow indicating arabinose positive.
Is p areuginosa gram positive?
Pseudomonas aeruginosa is a gram negative organism.It appears pink when stained by GRAMS technique.i.e., it takes the counter stain SAFFRANIN and appears pink in color.
What are the rules for adding numbers whose signs are different?
Positive plus positive is positive. Negative plus negative is negative. Positive plus negative is positive if the absolute value of the positive number is greater than the absolute value of the negative one. Positive plus negative is negative if the absolute value of the negative number is greater than the absolute value of the positive one.

A negative x a negative?
A negative times a negative is a positive. A simple way to remember this is... n * p = n p* n = n p * p = p n * n = p There will always be two negatives, and two positives.
Do transisors have polarity?
Basic transistors have three lead contacts that do have polarity . There are two kinds referred to as P-N-P (for positive-negative-positive leads) and N-P-N (for negative-positive-negative leads).
What is twenty divided by negative five?
The answer is negative four BECAUSE... 20/5 is POSITIVE four 20/-5 is a NEGATIVE four because a positive divided by a negative is a negative. Easy way to remember negs/pos: n * p = n p* n = n p * p = p n * n = p n / p = n p / n = n p / p = p n / n = p There are always two ways to get a positive, and two ways to get a negative. Very simple.
How do you divide a negative number by another negative number?
a negative number divided by a negative number is a positive number. This chart can be used to find the quotient or product when dividing and multiplying integers PNN NPN NNP for example, P P P means that a positive multiplied or divided by a positive = a positive.
How can you differentiate the pigment of p aeruginosa on pseudomonas agar P from the pigment of E coli on MacConkey agar without referring to the colors?

How do you write a equation when the sum of a positive number and several negative numbers will be positive?
if p represents your positive number, and n represents all of your negative numbers, then: |∑n| < p
Will p. aeruginosa grow on a blood agar media?
no
