Microbiology is a branch of biology concerned with the study of microorganisms such as bacteria, fungi, viruses, and algae. This major deals with understanding the structure, function, and behavior of these organisms and their impact on the environment and other living organisms, including humans.

Fields of study in microbiology:
Bacteria:

• Bacteriology: the study of classification, structure, growth, and reproduction of bacteria.
• Pathogenic bacteria: the study of diseases caused by bacteria and how to prevent and treat them.

Fungi (Mycology):

• Mycology: the study of the classification, structure, and functions of fungi.
• Pathogenic fungi: the study of diseases caused by fungi in plants, animals, and humans.

Viruses:

• Virology: The study of the structure, functions, and reproduction of viruses.
• Pathological viruses: studying diseases caused by viruses and methods of preventing and treating them.

Algae (Phycology):

• Algae science: the study of the classification, structure, and functions of algae.
• Use of algae: Study of how algae is used in industry, agriculture and the environment.

Molecular biology of microorganisms:

• Molecular techniques: The use of techniques such as PCR and genetic sequencing to study microorganisms.
• Genetic engineering: modifying genes in microorganisms to develop new applications.

Required skills:

• Research skills: the ability to design and conduct experiments and analyze results.
• Technical knowledge: Using modern tools and techniques in studying microbiology.
• Data Analysis: The ability to analyze and interpret biological data.
• Communication skills: the ability to write scientific reports and publish research.

Work fields:
