Bacteriology is the branch of microbiological sciences that focuses on the study of bacteria, encompassing their taxonomy, morphology, physiology, genetics, ecology, and roles in health, disease, and biotechnology. It investigates bacterial cell structure, growth kinetics, metabolic pathways, mechanisms of pathogenicity, antibiotic susceptibility and resistance, as well as horizontal gene transfer processes. Modern bacteriology integrates classical culture-based methods with molecular and genomic tools, including PCR, sequencing, and metagenomics, to characterize bacterial diversity and function. The field underpins clinical diagnostics, infection control, vaccine and antimicrobial development, industrial fermentation, environmental monitoring, and microbiome research.
Scientists have uncovered a new explanation for how swimming bacteria change direction, providing fresh insight into one of biology's most intensively studied molecular machines.
