What is the role of resazurin in fluid thioglycolate medium... - Answer-Resazurin indicates the presence of oxygen in the media A bacterial isolate is subcultured to two blood agar plates, one of which is incubated in an anaerobe jar, and the other is incubated on a shelf in the incubator. After incubation, growth is observed on the plate from the anaerobe jar, but there is not growth on the plate incubated on the incubator shelf. Based on these results how would this organism be categorize...

KIRBY-BAUER DISC DIFFUSION METHOD other term for antibiotic susceptibility test Zones of growth inhibition surrounding each type of disc were correlated with the minimum inhibitory concentrations of each antimicrobial agent. Principle: antibiotic susceptibility testing is often essential in order to determine which antibiotics to use against a specific strain of bacterium. Significant: culture and susceptibility test is the growth of a known pathogen in pure culture and ...

Antimicrobial Susceptibility testing -To determine which antimicrobial agents might be effective in treating infections -Need to disntinguish pathogens from commensals -Generally disk diffusion or dilution Reasons for Antimicrobial susceptibility -Suspect a isolate is involved in patient infection -Susceptibility against particular antimicrobial is uncertain Group A strep Susceptible to penicillin Epidemiological Cut-off valves (ECV) Helps identify emerging resi...

Diagnosis of typhoid fever during the first two days of illness can be confirmed best by: - ANS Blood culture n anaerobic gram-negative bacillus isolated from a blood culture following bowel surgery grew smooth, white, nonhemolytic colonies. A Gram stain showed a pale, BIPOLAR STAINING ROD WITH ROUNDED ENDS. BILE stimulated GROWTH of the organism and CATALASE was produced. The isolate was NOT INHIBITED by COLISTON, KANAMYCIN, or VANCOMYCIN; indole was not produced. The most likely id...
