General Microbiology is a first semester course.  It is a three -credit unit compulsory course which all students offering Bachelor of Science in  Microbiology must take.

Microbiology is a branch of biology which involves the study of microorganisms.  Microorganisms can be defined as living organisms which cannot be seen by the unaided eyes. These organisms include bacteria, fungi, algae, protozoa, viruses, etc.

Microorganisms are numerous in nature and have some characteristics which make them ideal specimens for the study of numerous fundamental like processes which occur at the cellular level in all living organisms. In microbiology, study of microorganisms is done extensively by observing their life processes while they are actively metabolising.

Microorganisms have a wider range of physiological and biochemical potentials than all other organisms combined. Some are able to utilise atmospheric nitrogen for the synthesis of proteins and other complex organic nitrogen compounds.

The study of microorganisms is applicable to all aspects of human endeavour including: medicine, food, agriculture, conserving human and animal reaction, combating diseases and used also as biological weapons. Some organisms are friends (beneficial) while others can be regarded as foes (harmful) to human beings.
