The Department of Microbiology & Immunology (M&I) occupies approximately 37,000 square feet of laboratory and office space. The majority of this space is located on the 3rd and 4th floors of the Truman G. Blocker, Jr. Medical Research Building which opened in 1991. In addition to this space, M&I investigators are located in the immediately adjacent Libby Moody Thompson Basic Science Building, the Galveston National Laboratory and the Keiller Building. All spaces are well equipped to support biomedical research. In addition to the more traditional biological safety level (BSL) 2 laboratories, the Galveston National Laboratory and Keiller buildings have BSL3 and BSL4 facilities to support both in vitro and in vivo studies requiring higher levels of containment.The Department also sponsors several of the many core facilities on campus. Specifically, the Tissue Culture Core Facility, a well-equipped Flow Cytometry Core, a state-of-the-art Optical Imaging Core, and a BSL3/BSL4 Aerobiology Core capable of doing regulated studies.
