Abstract
gene levels. The diagnostic accuracy rates for sheep blood, chocolate, Drigalski's and MacConkey agar were 0.79, 0.75, 0.73 and 0.64, respectively. When the cutoff was changed from 5 to 10 mm, the diagnostic accuracy rate for sheep blood agar decreased from 0.79 to 0.65. Our findings suggest that the type of agar medium impacts the string test results and sheep blood agar with a 5-mm cutoff is the optimal condition for detecting hvKp.
