Why are some bacteria able to grow on count agar that contains milk even though they do not produce any proteases?
Because plate count agar is still agar. therefore, it still has all the nutrients that bacteria require to grow.
What is the difference between nutrient broth and nutrient agar and can you elaborate more?
When 2%agar is added to nutrient broth ,it is called nutrient agar.Nutrition Broth is liquid media containing beef extract and peptone.Nutrition Agar is solid media containing beef extract, peptone, and agar
What reaction would you predict from an organism growing in litmus milk that has the following results in other media?
Assuming that you are asking about other media such as milk agar, PR lactose broth, purple lactose broth, and PR glucose broth, the answer you are looking for is as follows: A. A clear zone around the growth on a milk agar plate: indicates hydrolysis of casein, so should be clarification of medium present B. A/- in PR lactose broth: indicates lactose fermentation with acid and no gas produced, so should be pink litmus with acid clots and reduction of litmus in lower portion of medium C. A/G in purple lactose broth: indicates lactose fermentation with acid and gas produced, so should have pink litmus on top, acid clot, reduction of litmus, and fissures in the clot D. K in PR glucose broth: indicates peptone degradation with alkaline end products, so litmus should be blue
What chemical is extracted from red alga that is added to pudding and ice cream?
I believe you are talking about carrageenan, which is a gel-like substance that comes from a species of red algae called Irish moss. It is used as a thickening agent, not necessarily to emulsify ice cream. It is also used in evaporated milk and some pharmaceutical agents as well. :-)

What are the colonial features of staphylococus aureus in nutrient agar?
* Colonies are circular, 2-3 nm in diameter with a smooth shiny surface when grown on nutrient agar,milk agar or blood agar for 24 h at 37 degrees * Colonies are often pigmented,though a few strains are unpigmented Got the answers from here http://www.geocities.com/SouthBeach/Port/3008/staphyl.html

What are the general forms of media used in a microbiology laboratory?
Physical types of media include those that are liquid, such as broths and milk, those that are semi solid, and those that are solid. Kristian F.
What are the reservoirs of staph diseases?
* healthy people (''S.'' aureus'''' carriers): in the mucosa of the nose, less commonly in the throat, vagina, intestines and lungs; on the skin: mainly in the armpits, under the breasts, and in the groin; * infected people: in skin lesions, blood, stool, urine, respiratory mucosa, genitals, abscesses of internal organs; * animals: in pets (fur, skin, nares) and farm animals (cows udders, horses, poultry); * contaminated food: milk (from infected cow), food prepared and kept outside refrigerator (contamination from infected food worker); * athletic equipment, toys, workout surfaces; * air, water, soil, dust (less important sources). Primary reservoir for ''S.'' aureus'''' (including MRSA) is a human. Staph is common in cows (mastitis), poultry, and pets (dogs, cats). In Canada they've found MRSA in pigs (1). http://www.healthhype.com/tag/staph-reservoir
What can you use besides agar to grow bacteria?
Any type of liquid, even water, will do fine. Although agar is best recommended as it has a lot of nutrients, allowing lots of bacteria to grow. Other liquids work but they don't grow as much and as vigorously.
What agar is used to demonstrate the ability of some organisms to lyse red blood cells?
Organisms that can metabolize the sugar found in cow's milk have what enzyme
Should you breastfeed when you have a staph infection?
I personally would advise against it because the infection can be trasmitted from your breast milk to your baby. Read the related link below for more information.
What happens to milk when the suspended proteins are hydrolyzed?
If the casein in the milk is hydrolyzed it will lose its opaqueness. Therefore, if the bacteria have the exoenzyme capable of casein hydrolysis, there will be a clear zone around the bacterial growth. If the organism lacks the exoenzyme to break down casein the skim milk agar will remain white and opaque.
Why coliform show pink color colony in violet red bile agar?
Violet Red Bile Agar is recommended for use in the microbiological analysis of milk and other dairy products and for use in the examination of water. Violet Red Bile Agar is a selective medium which detects the growth of lactose fermenting coliforms. Coliforms colonies lower the pH of the medium subsequently causing their colonies to look red (neutral red dye) and to precipitate the bile salts. Crystal violet and bile salts inhibit the growth of Gram positive microorganisms.
