You patient tells you he has heard that N. gonorrhoeae is increasingly difficult to treat because of resistance to antibiotics. He asks whether it is possible to determine which antibiotics will be affective in treating his infection. You tell him that ________ indicate antibiotic susceptibility.
A) colony morphology
B) antibiograms
C) metabolic assays
D) 16S rRNA sequencing
E) MALDI-TOF MS assays

Question

Quizplus · Accepted Answer

Antibiograms are used to determine the sensitivity or resistance of an isolated bacterial strain to different antibiotics. This is done by growing the strain on a medium containing different antibiotics and observing which antibiotics inhibit growth. The results are presented in a chart format, which can be used to guide the selection of an appropriate antibiotic therapy. Colony morphology refers to the visual appearance of bacterial colonies and is not a reliable indicator of antibiotic susceptibility. Metabolic assays and 16S rRNA sequencing are used to identify bacterial species and are not primarily used for determining antibiotic susceptibility. MALDI-TOF MS assays are a type of rapid identification test and do not provide information on antibiotic susceptibility.
