List the three domains of life
1. Bacteria
2. Archaea
3. Eukarya
Some key contributors to microbiology history
- Ancestors of archaea & bacteria were the first life on Earth
- 1665 Robert Hooke coined the term “Cells” to describe the box-like
structures he saw in cork tissue. They reminded him of monks small rooms
cells. This marked the beginning of the cell theory that all living things
are composed of cells
- 1673 Anton van Leeuwenhoek observed the first microbes. He was a
Dutch clothes merchant. Now considered to be a genius. He originally
made microscopes to look at cloth fibres but ended up looking at things
like his teeth scrapings, his faeces and pondwater
- He was the first to see bacteria and protozoa which he called “animalcules”
(little animals)
Compare spontaneous generation and biogenesis
1. Spontaneous generation: The hypothesis that living organisms arise from
nonliving matter; a “vital force” forms life
2. Biogenesis: The hypothesis that the living organisms arise from preexisting
life
Word definitions related to the study of microbiology
- Bacteriology is the study of bacteria
- Mycology is the study of fungi
- Parasitology is the study of protozoa and parasitic worms
- Virology is the study of viruses
- Immunology is the study of immunity
- Toejamology is the study of fungal foot infections
