front 1 antibiotics | back 1 natural antimicrobial agents produced by microorganisms |
front 2 antimicrobials or antimicrobics | back 2 all substances used to treat bacterial infections |
front 3 Kirby Bauer test | back 3 also called the disk diffusion test, it measures the effectiveness of antimicrobics against pathogenic microorganisms |
front 4 How does the Kirby Baur test work? | back 4 antimicrobic impregnated paper discs are placed that is inoculated to form a bacterial lawn. the plates are incubated and upon being taken out, if the organism is susceptible to the drug, it will form a zone of inhibition |
front 5 zone of inhibition | back 5 clear zone around the disk where growth has been inhibited |
front 6 bactericidal | back 6 drugs that kill the organism |
front 7 bacteriostatic | back 7 drugs that stop growth but don't kill the microbe |
front 8 What is the depth that Kirby Bauer agar is poured and why is it so important the depth? | back 8 4mm deep in either a 150mm or 100mm petri dish
|
front 9 What kind of agar is used in Kirby Bauer method? | back 9 Mueller Hinton agar with a pH of 7.2 to 7.4 |
front 10 In Kirby Bauer method, the broth is diluted to match the _____ turbidity in the McFarland standard before inoculating the plate | back 10 0.5 |
front 11 How long are the discs containing the antimicrobial agent incubated in the Kirby Bauer method? | back 11 16 to 18 hours at 2 degrees Celsius |
front 12 antimicrobial susceptibility testing | back 12 used to measure the effectiveness of antibiotics and other chemotherapeutic agents on pathogenic organisms |
front 13 how does the antibiotic chloramphenicol work? | back 13 prevents peptide bond formation during translation |
front 14 how does the antibiotic ciprofloxacin work? | back 14 interferes with DNA replication |
front 15 how does the antibiotic trimethoprim work? | back 15 inhibits purine and pyrimidine synthesis |
front 16 how does the antibiotic penicillin work? | back 16 inhibits cross linking of the cell wall's peptidoglycan |
front 17 Bacterial resistance mechanisms to antibiotics can be broken down into three main types: | back 17 1. altered target such as antibiotic can no longer interact with cellular process
