MCB 2000 Lecture Notes - Lecture 1: Spirillum, Bioremediation, Bacteria
Document Summary
The 5 major groups of microorganisms: bacteria, algae, fungi, protozoa, and viruses. We will also study some other smaller groups such as prions and viroids. The one property that links these groups together is their very small size! A. bacteria (singular - bacterium) (study of bacteria bacteriology) 3. size: 1/1000 the volume of a typical eukaryotic cell. 2 groups (discovered in 1970"s) - we"ll discuss more later a. archaeobacteria - ancient bacteria b. eubacteria - true bacteria: some shapes: bacillus (rod), coccus (spherical), spirillum (spiral), vibrio (curved rod, motile or nonmotile. Heterotrophs: disease causing 2 examples: malaria & giardiasis (one of the don"t drink the water diseases ) Important note: we will consider a sixth group, the helminths (worms), in our study of microbiology. While most of the adult stages of these worms are macroscopic, many of them go through a microscopic stage in their life cycles (egg & larval stages).
