Study Notes
Microbial Taxonomy
- Genus Hom o includes species Homo sapiens.
- Genus Paramecium includes species Paramecium caudatum.
- Paramecium cells are cylindrical, long, and pointed at one end.
Five Kingdom Model
- Organisms are classified into five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia.
- Monera comprises prokaryotes, while Protista includes eukaryotic microbes like algae and amoebas.
- Early eukaryotic cells originated approximately 2 billion years ago, with the first cells appearing around 3-4 billion years ago.
Approaches to Phylogeny
- Carl Woese developed a new view of phylogeny in 1975, addressing the complexities of microorganism classification.
Naming Microbes
- Binomial nomenclature, established by Carl von Linné around 1735, assigns a genus and species name to each organism.
- Example of nomenclature: Staphylococcus aureus, where 'Staphylococcus' is the genus (last name) and 'aureus' is the species (first name).
- Naming sources include descriptions, habitats, dedications to researchers, and other factors.
Taxonomic Hierarchy
- Domain: Eukarya encompasses all eukaryotic organisms.
- Kingdoms include:
- Animalia: Involves multicellular organisms like lemurs.
- Protista: Includes protozoa and algae.
- Phyla examples:
- Chordata within Animalia.
- Ciliophora within Protista, contains only protozoa with cilia.
- Class hierarchy:
- Mammalia under Chordata.
- Hymenostomea under Ciliophora, known for single cells with regular rows of cilia.
- Orders detail more specific characteristics:
- Primates under Mammalia.
- Hymenostomatida under Hymenostomea, with elongated oval cells and oral cilia for feeding and movement.
- Family examples:
- Hominoidea within Primates.
- Parameciidae within Hymenostomatida, featuring rotating cells with oral grooves for swimming.
