archaea that live in intestines and produce gas
methanogens
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
HIV/AIDS, polio, flu, chicken pox, herpes simplex, ebola
characteristic of archaea
1. live in extreme environments
2. no peptidoglycan in cell walls
3. some produce methane
group of autotrophic bacteria that photosynthesize
cyanobacteria
contains bacterium's genetic material
nucleoid
example of retrovirus
HIV/AIDS
infectious particle made of abnormal proteins
prion
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
Gram staining
infectious particle with circular strand of RNA but lacking capsid or envelope (smaller than actual virus)
viroid
how vaccines work
weakened or inactivated virus to stimulate immune system
most common form of bacteria reproduction that produces two identical cells from one
binary fission
how bacteria benefits environment
decomposers--break down and return nutrients
used for __ therapy
gene
phase in which virus is present but not causing symptoms
Streptococcus mutans: shape??
coccus
3 parts of flagellum
filament, hook, motor
how cyanobacteria are beneficial
produce oxygen
use on farms
pesticides
future medical purpose
