Why do you suppose that plate counts for urine infections are made from the blood agar plate not the MAC plate?
Plate counts for urine infections are typically made from blood agar plates rather than MacConkey (MAC) plates because blood agar supports the growth of a wider range of bacteria, including fastidious organisms that may not grow well on MAC plates. Blood agar provides the necessary nutrients and allows for the detection of hemolytic activity, which can be important for identifying certain pathogens. Additionally, urine samples often contain mixed flora, and blood agar can help in isolating and quantifying the relevant pathogens more effectively.

Isolation media for actinomycetes?
Isolation media for actinomycetes typically contain nutrients like starch, casein, and soybean meal as carbon and nitrogen sources. Common isolation media include starch-casein agar, glycerol-asparagine agar, and oatmeal agar. Selective antibiotics like cycloheximide and nystatin may be added to inhibit the growth of other bacteria.
How do you change your cursor color on mac?
To change the cursor color on a Mac, go to "System Preferences," then select "Accessibility." In the Accessibility menu, click on "Display" and look for the "Cursor" tab. From there, you can adjust the cursor size and change its color by selecting from the available options. After making your adjustments, simply close the window, and your changes will take effect.
Is nutrient agar selective?
By definition, a selective medium is a medium that contains a substance that inhibits the growth of some types of bacteria but doesn't affect the growth of other types of bacteria (this is may be required when you want to isolate a specific type of bacteria from a specimen that contains other types of bacteria). Nutrient agar medium contains the following ingredients: peptone, meat extract, yeast extract, NaCl and agar. Nutrient agar doesn't contain any inhibitory substance for bacteria, therefore, it is not considered selective and instead it is called all-purpose medium. Answer An alternative definition of selective media is a media which allows the growth of some organisms whilst supressing the growth of others. Whilst nutrient agar contains no ingredients designed to supress growth, the composition is not suitable for the growth of certain microbes (fastidious bacteria) and so can be considered selective on this basis. For a case example try Mycobacterium lepraewhich is generally culitaved on living tissue rather than agar media. Nutriet agar is therefore selective in that certain microbes cannot grow on it. However, nutirent agar is generally considered the least selective media avalible. The confusion in answering the question arises in the catagories used to classify media in textbooks. Nutirent agar is suitable for the growth the vast majority of culturable bacteria, (however, it is estimated that only around 5% of the worlds bacteria can be cultured in the lab at present). As nutirent agar is sutiable for the growth of so many bacteria it may be catagorised as an "all purpose" media due to its suitablity for many different applications. However to researchers investigating new areas it is important for "all purpose" not to be confused with "all bacteria" media due to its selectivity. In summary, nutrient agar is selective but is classified "all purpose" as it is designed to allow the growth of many different species.

Lactose fermentation mac conkey test which color indicate a positive test?
MacConkey agar is yellow (due to the lactose in the agar). When an organism consumes the lactose, the agar turns purple. Purple indicates a positive test. If the organism doesn't use the agar, the agar stays yellow.
What is Mcconkey agar media?
It's a differential agar used to differentiate between lactose fermenters and non-lactose fermenteing bacteria. Chemical composition of Mac Conkey agar Peptone 20.0g Trehalose 10.0g Bile salts(Difco) 1.5g Sodium Cloride 5.0 Neutral Red 0.05g Crystal Violet 0.001 Agar 15.0g Distelled water 1.0 liter pH: 7.4±0.2 (25 °C)
Why did the colonies on the MAC plate turn pink?
The colonies that grew on MAC plate took up lactose from the medium for their metabolism and released an end product that caused the pH indicator of the medium (neutral red) to turn pink. Hence the colonies appears pink in color.
What is the Function of lactose in Mac Convey agar?
Lactose is used as a selective nutrient in the agar as not all microbes can process lactose
Can yeast grow on MAC agar?
Yes, yeast can grow on MacConkey (MAC) agar, although it is primarily designed for the isolation of Gram-negative bacteria, particularly enteric bacteria. MAC agar contains bile salts and crystal violet, which inhibit the growth of Gram-positive organisms, but many yeasts, such as Candida species, can still grow on this medium. However, the growth of yeast may not be as prominent or well-defined as that of bacteria.

What is a Mac plate?
A Mac plate is a dish made by combining macaroni and cheese with other ingredients like bacon, lobster, or truffles. It is a popular comfort food known for its indulgent and rich flavors.
What color is the best mac and cheese?
It is orange.
What is Toby mac's favorite color?
Green :)
What is the colony morphology of E. coli on nutrient agar?
I recently completed colony morphology on the E.colispecimen.The results displayed small colonies that were circular in shape, a diameter of approximately 0.5mm, the elevation of the colonies was seen to be slightly raised with the surface incredibly smooth.The colonies were also seen to have a pink colour pigmentation in Mac conkey agar due to its lactose fermenter after growth.The gram stain for these bacteria should be negative rod shaped.
