What is the material used as a base for bacterial culture media?
The substance is Agar or Agar-Agar
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
Prewarm agar plates?
before bacterial culture, the media containing agar i.e. solid agar should dry in the incubator, that is prewarm agar plate.
What does it mean to inoculate an agar plate?
to inoculate an agar plate you would place bacteria on the agar to grow
How to determine whether zone of inhibition is due to death of the bacteria or its inhibition?
If the compound you are testing is bacteriocidal, you will not be able to recover bacteria from the zone of inhibition. If the compound is only bacteriostatic, you should be able to recover bacteria from the zone of inhibition by scraping the surface of the agar and resupending the scrapings in sterile saline and then spreading an aliquot of the suspension on nutrient agar that does not contain the bacteriosttic agent.
What is the differences between zone of inhibition and zone of exhibition?
Zone of inhibition :-It is the area on an agar plate where growth of a control organism is prevented by an antibiotic usually placed on the agar surface. If the test organism is susceptable to the antibiotic, it will not grow where the antibioitic is. Zone of exhibition:-
Why have zone inhibition?
It is the area on an agar plate where growth of a control organism is prevented by an antibiotic usually placed on the agar surface. If the test organism is susceptable to the antibiotic, it will not grow where the antibioitic is.
What factors affect the zone of inhibition?
Pathogen susceptibility influences the zone of inhibition because organisms will not grow if they are susceptible to antibiotics. Another influence are the pH levels of agar which should fall between 7.2 and 7.4 room temperature.
What if a agar plate is isolated and antibiotic added and result is no growth or inhibition?
This is basically ANTIBIOTIC SENSITIVITY TEST, to test whether the given organism is RESISTANT(no zone of inhibition) or SENSITIVE( zone of inhibition) to the given antibiotic.Zone of Inhibition Testing is a fast, qualitative means to measure the ability of an antimicrobial agent to inhibit the growth of microorganisms.The effectiveness is based upon the size of zone of inhibition,diffusability of antibiotic,size of inoculum,type of media used.example: bacillus organism is inoculated with both PENICILLIN and AMPICILLIN ,zone of inhibition is absent in case of penicillin and present in case of ampicillin, this shows that ampicillin (sensitive) worked effectively when compared to penicillin.
How do you find antibiotic assay?
For determining the type of causal agent of infectious diseases and for checking their sensitivity to antibiotics and chemotherapeutic agents in vitro by means of the inhibition zone determination method. The antibiogram allows rational and selective chemotherapy. The test discs can be coated with chemotherapeutic agents, placed on the innoculated nutrient agar and incubated. The size of the inhibition zone is a measure for the effectiveness of the substances.
Agar agar grain found in Germany?
Agar, or agar-agar, is not a grain, but rather an extract of seaweed. Agar translates to German as Agar-Agar Try whole- or health-food stores
