Because nutrient agar pH is low and it has less property to antibiotic diffusion that;why we use MHA for antibiotic suseptibility testing on ph variation antibiotic does not properly work

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 is Antibiotic Sensitivity Test?

Answer1.It is a skin test in which a drop of an specific antibiotic is placed under your skinfor checking if you have any allergic reaction to it.2. Antibiotic sensitivity test or Antimicrobial sensitivity test is a laboratory test done inmicrobiology labs to find out the correct antibiotic to use in the therapy of aparticular disease producing bacteria.


What do the sensitivity numbers mean on a urine culture and sensitivity test?

The sensitivity numbers on a urine culture and sensitivity test indicate the effectiveness of different antibiotics in treating a specific bacteria found in the urine sample. It helps determine which antibiotic will be most effective in treating the infection. The higher the sensitivity number, the more effective the antibiotic is against that particular bacteria.


Antibiotic sensitivity disk?

Antibiotic sensitivity disks contain a specific concentration of an antibiotic to test the susceptibility of a particular bacterial strain to that antibiotic. The zone of inhibition around the disk indicates the effectiveness of the antibiotic against the bacteria present. This method helps healthcare professionals identify the most appropriate antibiotic for treating bacterial infections.


What is an A disk in microbiology?

You'd have to be more specific in your question. However, disks are often laden with antibiotics to see if a bacteria is resistant or susceptible to that antibiotic. The disk is placed on a nutrient agar and then bacteria is spread onto that disk. If the bacteria is susceptible to that antiobiotic, it will grow on the nutrient plate, but not around the disk containing the antibiotic. The larger the clear area around the disk, the more susceptible the bacteria is to that antibiotic. If it is resistant to that antiobiotic, it will grow on the plate and adjacent to the antibiotic laden disk indicating that antibiotic is not effective towards that particular bacterial strain. In one such test the A disk had bactracin. However, I am not comfortable saying that all A disks have bactracin. How the disk is labeled may differ.

What is the difference between Kirby-Bauer and mueller-hinton?

Kirby-Bauer is the diffusion method you would use to test antibiotic sensitivity. The Mueller-Hinton is the agar plate in which you would do the method on. This is where the antibiotic discs would be places to test the sensitivity.

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.


What is susceptible numbers on a culture and sensitivity test mean?

Susceptible on a culture and sensitivity test means that the bacteria being tested is vulnerable to the antibiotic being used. This implies that the antibiotic is likely to be effective in treating an infection caused by that specific bacteria.


What role does antibiotic culture and sensitivity play on prescription?

For a frank case of infection prescription of an antibiotic is made from the doctor's clinical experience. Smear, culture, antibiotic sensitivity test report takes time to arrive. After seeing the report prescription is made for the antibiotic to which the patient's microorganisms are susceptible.

What is the purpose of culture and sensitivity testing?

its a test which helps find what organism (usually bacteria) is causing an illness. Its also a test that helps find what antibiotic is best to treat the illness


Blood culture and sensitivity?

Blood culture is a test to detect the presence of bacteria or fungi in the bloodstream, which can help diagnose infections like sepsis. Sensitivity testing is performed to determine which antibiotic is best to treat the specific organism identified in the culture. This information is crucial for guiding appropriate antibiotic therapy for the infection.
