Medical Microbiology

Microbio LabMedical Microbiology faculty members provide a comprehensive range of diagnostic tests and are organized into specialty sections that are staffed by highly skilled clinical laboratory scientists.

In the bacteriology section, aerobic and anaerobic organisms from human body fluids and tissues are identified. Antimicrobial susceptibility testing is performed using automated and manual methods. Mycobacteria species are identified using traditional culture and molecular methods and susceptibility testing is performed on first-line drugs used to treat M. tuberculosis.

In the mycology area, direct examinations, culture, biochemical and MALDI-TOF-MS methods are used to identify clinically relevant fungi and yeast. Parasitology specimens are processed using direct and concentration procedures and evaluated using wet mounts and permanent stains.

In the virology section, direct tests, cell culture techniques and molecular methods are used to identify and quantify viral pathogens. Methods have been incorporated into the serology section to detect antibodies and antigens important to the diagnosis and treatment of infectious diseases. The medical microbiology group is committed to emphasizing clinical applicability, accurate and rapid results and cost effectiveness.
