Microbiology lab antibiotic sensitivity

University of Miami Biology Department House Rabbit Society of Miami If your bunny has an infection of any kind--from an upper respiratory infectionto a jaw abscess to a urinary tract infection --it's critical to know which antibiotics will be effective against the particular pathogen i. This means that 1 the species and strain of bacteria or other pathogen must be identified and 2 the drugs most effective at inhibiting their growth must be determined. The only reliable way this can be done is a culture and sensitivity test. In modern laboratories, bacteria are usually identified by characterization of the genome:

Microbiology lab antibiotic sensitivity

Introduction It is not enough to just identify your organism. You also need to know what antimicrobial agents your organism is susceptible to. There are several methods to determine this. This is done by adding two-fold dilutions of the antimicrobial agent directly to an agar pour, a broth tube, or a micro-broth panel.

The lowest level that inhibits the visible growth of the organism is considered the Minimum Inhibitory Concentration MIC. The agar pour method is considered the reference test procedure in Europe. The broth dilution method is more widely accepted in North America.

The E test AB Biodisk is a plastic strip with a gradient concentration of antimicrobial agents impregnated in it.

Culture and Sensitivity Testing Sagar Aryal Bacteriology In the treatment and control of infectious diseases, especially when caused by pathogens that are often drug resistant, susceptibility sensitivity testing is used to select effective antimicrobial drugs. Susceptibility tests must never be performed on commensal organisms or contaminants because this would mislead the clinician and could result in the patient receiving ineffective and unnecessary antimicrobial therapy, causing possible side effects and resistance to other potentially pathogenic organisms.
Lab 3 - Antibiotics - 7B Science Labs Advanced Search Abstract An important task of the clinical microbiology laboratory is the performance of antimicrobial susceptibility testing of significant bacterial isolates. The goals of testing are to detect possible drug resistance in common pathogens and to assure susceptibility to drugs of choice for particular infections.
Microbiology Labs Play an Important Role in Antimicrobial Stewardship Eden Ogbai Microbiology Lab Report: Over the past eighty years, subsequent the Golden Age of microbiology, bacteriologists Alexander Fleming presented innovativeness in medical research with the discovery of Penicillin antibiotic specifically Penicillum notatum to counteract the growth of bacterium Staphylococcus aureus S.

The strip is placed directly on the surface of an inoculated plate. The MIC is read from the strip where the growth inhibition intercepts the disk. These strips are relatively expensive. Many physicians however do not need no know the exact MIC, but just which antibiotics the pathogen is susceptible, intermediate, or resistant to.

The Kirby-Bauer agar diffusion method is well documented and is the standardized method for determining antimicrobial susceptibility. White filter paper disks 6 mm in diameter are impregnated with known amounts of antimicrobial agents.

Each disk is coded with the name and concentration of the agent. The drug diffuses through the agar. The plates are incubated for hours.

The agar may be supplemented with blood or you may use blood agar for fastidious organisms. The diameter of the visible zone of inhibition is measured and compared to reference values. There should be sufficient bacteria to form a visible lawn of growth where it is not inhibited by the drug.

The results are interpreted qualitatively as resistant, intermediate, or susceptible. The standard protocol must be followed exactly for you, or any clinical lab, to interpret the results reliably.Antibiotic sensitivity testing, Skills in Microbiology Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising.
