disease
gonorrhea
When to get tested?

gonorrhea or are

MRSA SCREEN
The goal of laboratory
testing for staph wound
infections is to identify the
presence of S. aureus, to
determine whether it is a
MRSA strain, and to
evaluate the staph’s
susceptibility to available
antibiotics. If an infection is
due to MRSA, it should be
investigated to determine
where it came from and
how it was acquired. This is
especially important in CA-
MRSA to prevent further
cases from occurring.
VRE SCREEN
VRE are specific types of
antimicrobial-resistant
staph bacteria. While most
staph bacteria are
susceptible to the
antimicrobial agent
vancomycin some have
developed resistance. VRE
cannot be successfully
treated with vancomycin
because these organisms are
no longer susceptibile to
vancomycin. However, to
date, all VRE isolates have
been susceptible to other
Food and Drug
Administration (FDA)
approved drugs.
