Microbiologist research challenges information found in immunology.
Microbiologist . Most microbiologists specialize in environmental , food , agricultural , industrial or medical aspects of microbiology including : virology ( the study of viruses ) ; immunology ( the study of mechanisms that fight infections ) ; bioinformatics ( the methods for storing , retrieving , organizing and analyzing biological data ) and Bioremediation ( using microbes as environmental mitigation strategies ) . Because microbiologists specialize in the investigation of microorganisms that typically cause infection , their research commonly promotes information found in immunology , pathology , and molecular biology .
