This paper will enable students:
To have an insight in to history of microbiology
To study different types of classification systems
To understand the structure of bacterial cell
To study salient features of different bacterial groups
Leeuwenhoek’s discovery of microorganisms, theory of abiogenesis and biogenesis, Germ theory of fermentation, Germ theory of diseases.
Eukaryotic and Prokaryotic cell structure:
Levels of classification, Haeckels three kingdom concept, Whittakers five kingdom concept, three domain concept of Carl Woese and major characters of primary domains.
Bacterial shapes and arrangement, cell membrane, cell wall of bacteria, inclusion bodies, flagella, capsule, slime, fimbriae, and pilli.
Bacterial endospores- structure, formation and germination.
A brief outline of bacterial classification according to Bergey’s manual of systematic bacteriology second edition (2004) with salient features of the following:
Proteobacteria: alphaproteobacteria (Rickettsia), betaproteobacteria (Thiobacillus), gamma proteobacteria (Pseudomonas, E. coli), deltaproteobacteria (Myxococcus) and epsilonproteobacteria (Campylobacter); Non proteobacteria Gram negative bacteria (cyanobacteria, purple and green photosynthetic bacteria)
A brief outline of bacterial classification according to Bergey’s manual of systematic bacteriology second edition (2004) with salient features of the following:
Gram positive bacteria: firmicutes (Mycoplasma, Staphylococcus and Streptococcus), Actinobacteria (Streptomyces, Mycobacterium), Chlamydiae, Spirochaetes, Archaebacteria (halophiles and thermophiles).
