Study Notes
Course Overview
- MCB 102 is an introductory course in microbiology for undergraduate students.
- Aims to provide foundational knowledge in basic and applied microbiology.
- Course includes both theoretical lectures and practical sessions to develop skills in microbial study.
- Assessment comprises Continuous Assessment (C.A.) at 40% and semester exams at 60%.
Introduction to Microbiology
- "Micro" indicates very small organisms observable only with a microscope.
- Microbiology focuses on microorganisms or microbes, which are typically invisible to the naked eye.
- Microbes are found ubiquitously in various environments and living organisms.
- A small fraction of microbes are pathogens that lead to infectious diseases.
Impacts of Microorganisms
- Microbes play essential roles in daily life, including:
- Cycling and recycling of elements like carbon, oxygen, and nitrogen.
- Bioremediation and cleanup of toxic wastes.
- Applications in genetic engineering and gene therapy.
- Some microorganisms are responsible for diseases, such as:
- Cholera caused by Vibrio cholerae.
- Tuberculosis caused by Mycobacterium tuberculosis.
- Typhoid fever caused by Salmonella typhi.
- Bacillary dysentery caused by Escherichia coli.
- Anthrax caused by Bacillus anthracis.
- Malaria caused by Plasmodium falciparum.
- Candidiasis caused by Candida albicans.
Classification of Microorganisms
- Microorganisms are commonly classified into several groups:
- Bacteria: Studied in Bacteriology. Examples include Staphylococcus aureus and E.coli.
- Fungi: Studied in Mycology. Examples include Penicillium sp., Aspergillus sp., and Candida sp..
- Protozoa: Studied in Protozoology. Examples include Entamoeba sp., Plasmodium sp., and Giardia sp..
- Algae: Studied in Phycology. Includes similar examples to protozoa regarding specific types.
- Viruses: Studied in Virology. Not considered living due to acellular nature; examples include Polio virus and HIV.
Distinction of Archaea
- Archaea are prokaryotic organisms that differ from bacteria in key aspects:
- Unique ribosomal RNA sequences.
- Absence of peptidoglycan in cell walls.
- Distinct membrane lipids.
