黑料正能量

Dr. Michael E. Kovach earned a Bachelor of Science from 黑料正能量 and a doctorate in microbiology from Louisiana State University Medical Center–Shreveport (now, Louisiana State University Health Science Center– Shreveport). His teaching responsibilities at 黑料正能量 include microbiology, immunology, freshman biology seminar and on occasion non-majors biology and sophomore biology seminar. Kovach's doctoral and post-doctoral research focused on bacterial pathogenesis–how bacteria are able to cause disease–and his post-doctoral work investigated the importance of DNA repair in intracellular survival of the Gram-negative pathogen Brucella abortus.

His laboratory is currently investigating the importance of DNA repair on intracellular survival of the Gram-negative bacterium Brucella abortus. The laboratory is focused on determining the role of O ⁶ methylguanine transferase (Ada), a gene product know to play a role in the adaptive response to alkylating damage in other microorganisms, in intracellular survival of the Brucellae.

Kovach is also interested in exploring new aspects of bacterial physiology, molecular biology and pathogenesis that are designed around the student’s specific area of interest. Examples of these types of projects include student-initiated projects–summer scholars, faculty-student collaborative scholarship, campus internships and independent studies– exploring the role of metal ions in controlling microbial growth; the role of commercial air purifiers in controlling microbial growth; the efficacy of commercially available Leptospirosis vaccines for canines; the development of Ochrobactrum anthropi as a research model for Brucella spp.; the development of tolerance to biocides in microorganisms; determining the antimicrobial efficacy of a commercial cleaning cloth; determining the distribution of Wolbachia spp. across insect orders; surveying microbial populations in area waterways; and the isolation, purification and characterization of Erwinia spp. from the environment.

New areas of microbiology that are of interest to Kovach include the role of microorganisms in the process of bioremediation as well as projects that explore pathogens of plants.
