Cellular microbiology is a branch of microbiology that focuses on the interactions between microbial pathogens and host cells. This area of research explores how microbes invade, survive, and replicate within host cells, as well as how host cells respond to infection. Cellular microbiology also investigates the mechanisms of pathogenesis, immune evasion, and drug resistance in microbial pathogens. Researchers in this field use a combination of genetic, molecular, and cell biology techniques to study these complex interactions at the cellular level. Ultimately, the goal of cellular microbiology is to better understand the molecular basis of infectious diseases and develop new strategies for prevention and treatment.
