Thomas R. Fritsche, M.D., Ph.D., Division of Laboratory Medicine, Clinical Microbiology Section

Dr. Fritsche has worked in the fields of diagnostic clinical microbiology, parasitology, antimicrobial susceptibility testing and resistance emergence. Collaborations have involved the study of novel bacterial endosymbionts occuring within free-living amoebae, and the role of protozoa as professional phagocyte mimics. Such evolutionary relationships may have implications for the preadaption and/or recruitment of recognized intracellular pathogens such as the Chlamydiales and Rickettsiales for metazoan hosts.
