How antibiotics control bacteria
Killing them, Slowing their growth
keeps bacteria from drying out, makes difficult to be engulfed by immune cells
capsule
parts of viruses
capsid, envelope--no cellular structures
Example of virus

characteristic of archaea
1. live in extreme environments
2. no peptidoglycan in cell walls
3. some produce methane

basic shape(s) of bacteria
spirillum, bacillus, coccus
live in guts of organism
microbiota
Used to classify bacteria, detects amounts of peptidoglycan in cell walls, can predict whether antibiotic will be effective
