Bacteriology

Bacteriology is the specialized branch of microbiology focused on the study of bacteria, a vast domain of single-celled prokaryotic microorganisms. This scientific discipline investigates the morphology, ecology, genetics, and biochemistry of bacteria, as well as their identification and classification. A crucial area of biology, bacteriology examines the profound impact of bacteria on all life, exploring their roles as pathogens that cause disease, their essential functions in ecosystems like nutrient cycling, and their applications in medicine, agriculture, and industrial biotechnology.
