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.
Vibrio bacteria are major pathogens in the aquaculture industry, triggering vibriosis—a disease that can cause mortality rates of up to 90% within two days. This not only results in billions of dollars in economic losses ...
