The Department of Microbiology and Immunology is a Biomedical Science Department within the School of Medicine at San Juan Bautista School of Medicine. The Department administer the Immunology course and Medical Microbiology courses to our health professionals’ students. Our students are involved not only in regular class activities, but we also incorporate innovative instructional and learning methodologies to complement the course lectures using integrated exercises directed to apply the basic microbiological and/or immunological problems to solve medical problems.

The Department works multidisciplinary together with the other departments in the implementation of the organ-based curriculum of the medicine program and to our other health professional programs. Our faculty teaches and conducts research on infectious microbes and immune system. Our mission is to advance knowledge in the areas of bacterial multidrug resistance, and immuno-nutrition to build up the knowledge necessary to better understand microbial pathogenesis and the discovery of future antimicrobial treatments.

We strongly believe that our students have an incredible opportunity to make relevant professional and scientific advances and contributions while at SJBSM as well as after graduation, whether they work in hospital, academia, health administration or any other clinical or healthcare organization.
