Virology examines viruses, which are obligatory intracellular parasites that cannot
multiply without a host cell and are devoid of cells.
This includes studying viral architecture, classification, genetics, replication
mechanisms, host-virus interactions, and modes of transmission.
Virology is critical to the advancement of biotechnology, gene therapy, vaccine
development, and antiviral drug development.
3. Mycology
The branch of science known as mycology is concerned with the study of fungi,
which includes yeasts, molds, and mushrooms.
The subjects covered include the ecology, genetics, reproduction, physiology,
morphology, and taxonomy of fungi.
Mycologists study both beneficial fungi (used in antibiotics, food manufacture like
beer and bread, and biodegradation) as well as harmful fungi that cause plant
diseases (e.g., rusts and smuts) and human infections (e.g., candidiasis, and
aspergillosis).
4. Phycology
The branch of microbiology that studies algae, which are photosynthetic eukaryotic
microorganisms that can be found in terrestrial, freshwater, and marine
environments, is known as phycology, or algology.
