Why cant you use the same selective and differential media for staphylococci and streptococci?
Staphylococci and Streptococci grow in different locations under different conditions. Staphylococci are found on skin surfaces and nasal path whereas Sptreptococci are found in the intestinal and urinary tract. Thus, due to difference in the growth conditions and biochemical processes, we need to use different selective and differential media for them.Binod,Toronto, Canada
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.
Which culture medium preparation is most commonly utilized in isolation of pure culture?
Solid media is used for the isolation of bacteria as pure culture. 'Agar' is most commonly used to prepare solid media.
Is nutrient agar good for actinomycetes isolation?
Nutrient agar is not the ideal medium for isolating actinomycetes. Actinomycetes typically require specialized media such as starch-casein agar or Gause's synthetic agar for isolation due to their specific nutritional requirements and growth characteristics. These media are designed to promote the growth and isolation of actinomycetes more effectively than nutrient agar.
Will p. aeruginosa grow on a blood agar media?
Yes, Pseudomonas aeruginosa can grow on blood agar media because it is a non-selective medium that provides essential nutrients for bacterial growth. However, its growth on blood agar may not be as robust as on selective media designed specifically for its isolation and identification.
What are the two types of reporting isolation events are observer-reported and media reporting?
FALSE

How did media effect the war in Iraq?
The American public was excited during the initial phases of Operation Iraqi Freedom in 2003; just as they were during the 45 day campaign of Operation Desert Storm in January/February 1991. After those initial "days", both campaigns degenerated into no activity.
What makes the isolation of media faults on a ring topology network easy?
Each device is a repeater
Whitney Houston was she pregnant when she did the movie the bodyguard?
Actually, she may have been in the initial stages of pregnancy, but it was only announced afterwards; and during the media tour for the film, she suffered a miscarriage.

Isolation of phosphobacteria?
Phosphobacteria added to the soil can increase the available phosphorous in the soil. Biochemical companies are working isolation of phosphobacteria in volcanic soils to increase production and potency for use in ground treatments.
What are the selective media for isolation of thermophiles?
Selective media for isolation of thermophiles include Thermus agar, which contains nutrients favoring growth of thermophiles, and inhibitory substances that limit the growth of other organisms. Other selective media may contain antibiotics or chemicals that only allow the growth of thermophiles due to their specific metabolic characteristics at high temperatures.
Why is Msa argar a selective medium?
Mannitol Salt Agar is selective for staphylococci as the high salt (sodium chloride) levels prohibit most other bacteria from surviving and it is differential as Staphylococci ferment mannitol, producing acid, lowering the pH and turning the media yellow. The development of yellow media presumes the bacteria to be pathogenic Staphylococcus (usually S. aureus). From A Photographic Atlas for the Microbiology Laboratory by Leboffe and Pierce.
