Question #14 explained
Which of the following is consistent with the definition of asymptomatic bacteriuria (ASB) in a non-catheterized woman according to the Infectious Diseases Society of America guidelines on the diagnosis and treatment of ASB?
A. Two non-contaminated voided urine specimens collected with isolation of the same bacterial strain in quantitative counts of 100,000 colony forming units/mL or more CORRECT
B. One non-contaminated voided urine specimen collected with isolation of the same bacterial strain in quantitative counts of 100,000 colony forming units/mL or more
C. Two non-contaminated voided urine specimens collected with isolation of the same bacterial strain in quantitative counts of 10,000 colony forming units/mL or more
D. Two non-contaminated voided urine specimens collected with isolation of any bacteria in quantitative counts of 100,000 colony forming units/mL or more
Answers B-D can be compared to answer A to show why they are not correct.
Note 1: In a male, ASB is defined as a single clean-catch voided urine specimen with 1 bacterial species isolated in a quantitative count of 100,000 colony forming units/mL or more.
Note 2: In a catheterized male or female, bacteriuria is a single adequately collected catheterized urine sample with 1 bacterial species isolated in a quantitative count of 100 colony forming units/mL or more.
