Department of Microbiology


  • Evaluation of mechanisms of antibiotic resistance among respiratory pathogens

    • Antimicrobial susceptibility testing of nontuberculous mycobacteria and other aerobic actinomycetes
    • Molecular biology of tetracyclines, macrolides, aminoglycosides and penicillin resistance in these same species
    • Character of ß-lactamase enzymes in Nocardia, mycobacteria, and Moraxella (Branhamella) catarrhalis and their role in penicillin resistance

  • Utilization of DNA fingerprinting as a tool to study the epidemiology of infections and antibiotic resistant strains of bacteria/mycobacteria utilizing PCR and pulsed field gel electrophoresis (PFGE)
    • Hospital acquired outbreaks and pseudo-outbreaks due to nontuberculous mycobacteria including Mycobacterium avium in AIDS patients and non AIDS patients, M. chelonae, M. abscessus, M. fortuitum, M. xenopi, and M. kansasii
    • Outbreaks due to Mycobacterium tuberculosis
    • Outbreaks due to other bacteria
    • Relapse isolates in patients on new drug trials to determine relationship to pretreatment strains

  • Investigations of role/efficacy of new antimicrobials in the therapy of human infections

    • Drug resistant tuberculosis

    • Respiratory and skin infections due to nocardia, environmental mycobacteria and nontuberculous mycobacteria

    • Chronic lung disease due to nontuberculous mycobacteria, especially Mycobacterium avium complex
  • Taxonomy of nontuberculous mycobacteria and other aerobic actinomycetes
    • Identification, characterization, naming of new species
    • Identification of nontuberculous mycobacteria and other aerobic actinomycetes by PCR technology

The Department of Microbiology supports the mission of UT Health Northeast by providing excellence in research, education and patient care. Projects include grants, contracts and agreements - both from public and private sectors - which support research, education and patient care.
