bacteria

single-celled prokaryotic small microorganism

- staphylococci = grape cluster (boils, acne)

- streptococci = line, chain

- diplococci = double pairs (meningitis)

viruses

DNA/RNA surrounded by protein coat, only in living cells bc they aren't living, acellular, smallest micro

- smallest infectious agent

- sub cellular (include gene info)

- most common = influenza, hepatitis, warts

Protozoa

eukaryotic: highly complex, nuclear and cytoplasms, organelles

- single-celled, larger than bacteria, majority aren't pathogenic

- leading cause of death in developing countries

fungi

single-celled or multi-celled, eukaryotic (rigid cell wall)

- depend on other life for food

- yeasts: mainly single-celled and reproduce by budding

- molds: fungi turn into fuzz, bigger multi celled organisms producing spores

mainly harmless/superficial
