MLT 415 -Lab Report (Antibiotic Sensitivity Test) M. Mohamad Zan. The zone of inhibition is measured in millimetres by using ruler and internal calliper. The edge of this zone correlates with the antibiotic concentration that inhibits the growth of the bacteria. The width of the zone is compared to a standard table When antibiotic sensitivity testing is reported, it will report the organisms present in the sample, and which antibiotics they are susceptible to. Although antibiotic sensitivity testing is done in a laboratory ( in vitro ), the information provided about this is often clinically relevant to the antibiotics in a person ( in vivo ). [28
Antibiotic sensitivity test is a procedure done to identify the susceptibility of a microbe to a suitable antibiotic. This is determined by the extent of inhibition of growth of a specific microbe when treated with a set of antibiotics. The antibiotic which inhibits the growth to a large (greater) extent is the concluded to be the best one to. Antimicrobial susceptibility tests (ASTs) basically measures the ability of an antibiotic or other antimicrobial agent to inhibit the invitro microbial growth. There are many different procedures that microbiologists use to study the effects of various antimicrobial agents in treating an infection caused by different microorganisms The test panels are standard 96-well microdilution plates that can be inoculated with a Sensititre Autoinculator. Growth is determined by fluorescence measurement after 18-24 h of incubation. Test panels are available for gram-positive and gram-negative bacteria, S. pneumoniae, Haemophilus species, and nonfermentative gram-negative bacilli A sensitivity analysis is a test that determines the sensitivity of bacteria to an antibiotic. It also determines the ability of the drug to kill the bacteria Estimated ratio of antibiotic prescribing (laboratories that report antibiotic/laboratories that do not report antibiotic) 95% CI P value Cephalosporins 1.40 0.75-2.64 0.26 Quinolones 1.35 0.98-1.86 0.06 Norfloxacin 1.29 (laboratories that report quinolones/laboratories that do not report quinolones) 0.29-5.80 0.7

After the streaking is complete, allow the plate to dry for 5 minutes. Antibiotic discs can be placed on the surface of the agar using sterilized forceps. Gently press the discs onto the surface of the agar using flame sterilized forceps or inoculation.
The tests are performed under standardized conditions so that the results are reproducible. The test results should be used to guide antibiotic choice. The results of antimicrobial susceptibility testing should be combined with clinical information and experience when selecting the most appropriate antibiotic for your patient Antimicrobial sensitivity test 1. ANTIBIOTIC SENSITIVITY TEST 2. Antibiotic • An antibiotic is a substance produced by various species of living microorganisms. • (e.g. bacteria and fungi) Terminology: Bacteriostatic: Bactericidal: Minimum inhibitory concentration: • MIC is the smallest amount of an agent needed to inhibit growth of a microorganism. Minimum bactericidal concentration. Some microbes are very sensitive to a particular antibiotic while others are not and the sensitive ones are again resistant to some other antibiotic. To find out the sensitivity of one microorganism against different antibiotics, the test organism is spread on an agar plate and different antibiotics of high conc. (100 µgm./ml) are applied in.
This is the concentration of an antibiotic that inhibits the particular organism known as the Minimum Inhibitory Concentration (MIC). This tells you the level of antibiotic that is associated with effective treatment of the infection and the lowest concentration you need to treat that organism. A lower MIC is an indication of a better antimicrobial agent It is also likely that if antibiotic sensitivity tests were run on these isolates, the results would vary against the different antibiotics used. The Kirby-Bauer test for antibiotic susceptibility (also called the disc diffusion test) is a standard that has been used for years. First developed in the 1950s, it was refined and by W. Kirby and A.
An antibiotic sensitivity (or susceptibility) test is done to help choose the antibiotic that will be most effective against the specific types of bacteria or fungus infecting an individual person. Some types of bacteria or fungus are resistant to certain antibiotics because of differences in their genetic material (genes) Antibiotic Sensitivity. Antibiotic susceptibility testing (AST) is an in vitro measure to assess the likelihood that a particular antimicrobial agent will treat an infection caused by a particular organism.

It is the most important cause of economic losses to the dairy industry in India and throughout the world Antibiotic resistance in bacteria is a serious global public health threat. According to the Centers for Disease Control and Prevention (CDC), 2 million people in the U.S. develop antibiotic-resistant infections each year, and at least 23,000 people die from those infections
The antibiotic sensitivity or susceptibility test helps to select an appropriate antibiotic that is effective against specific types of bacteria or fungi causing any infection. This test needs to be conducted as some types of bacteria or fungi are resistant to certain antibiotics and infections, and they are not cured by treatment with those. Susceptibility is the likelihood that a particular antibiotic will be effective in killing or sufficiently inhibiting the growth of specific bacteria that is causing an infection. Susceptibility testing measures whether or not the bacteria can grow when it is exposed to a variety of antibiotics in a laboratory test

Rapid bacterial analysis and testing for antibiotic sensitivity demonstrated A scanning electron micrograph of a polymicrobial sample with E. coli (rod-shaped) and S. aureus (spherical). By developing a single cell analysis technique, the research team demonstrates rapid classification of the bacteria and determination of their antibiotic. Antibiotic susceptibility, sometimes termed antibiotic sensitivity, is the responsiveness of a microbe an antibiotic. Depending upon the antibiotic employed, susceptibility can vary between species as well as among strains of the same species. Susceptibility of a microbe to a particula The test most widely used for determining the antibiotic(s) to be used to treat an infection is the Kirby- Bauer method. The suspected pathogen is isolated in pure culture from a clinical specimen and is tested for its sensitivity to clinically attainable levels of several antibiotics The Kirby-Bauer Method, also known as the disk fusion method, is the most commonly used antibiotic susceptibility test to determine which antibiotics should be used to treat infections (Bauer 1966). Selected E. coli cultures from the Coliscan ® Easygel® plates were transferred utilizing sterile technique from Mueller Hinton broth to Mueller.

[This is an attempt to convey some of the important points raised but the contents cannot satisfactorily be summarized and the report should be read in full by all concerned with the performance of antibiotic microbial sensitivity tests.] D.D. Smith Similarly when antibiotic sensitivities are being entered, the specific organism number-for example, SENS 1 or SENS 2, is declared andthen the required sensitivity pattern is input merely by selecting S (sensitive), I (intermediate) or R (resistant) opposite the requiredantibiotics. Asmanyantibiotics as required can be input in this way.
Phage therapeutics are uniquely positioned to address the threat of antibiotic-resistance as they can be precisely targeted to kill select bacteria, have a differentiated mechanism of action, can penetrate and disrupt biofilms (a common bacterial defense mechanism against antibiotics), are potentially synergistic with antibiotics and have been shown to restore antibiotic sensitivity to drug. These tests can be used on farm to test individual cows or used in a laboratory setting to screen large quantities of samples. The sensitivity of these tests to detect tetracycline and sulfonamide drugs closer to government regulations make these unique in the inhibition test market
