Bacteria Flashcards
G+ coccus?
Streptococcus & Staphylococcus
G+ Spore forming rods
Bacillus and clostridium
G+ non-spore forming rods
Corynebacterium, listeria
which G- pathogen is spiral shaped?
Spirochetes, including Treponema pallidum (syphilis)
Layers of G+ cells? lipid content of G+? what can kill it?
- inner cytoplasmic membrane
- outer thick peptidoglycan layer
low lipid content
vulnerable to lysozyme and penicillin attack
Layers of G- cell?
lipid content?
endotoxin?
what can attack it?
(1) inner cytoplasmic, (2) thin peptidoglycan layer, (3) outer LPS layer
high lipid content, endotoxin is LPS - Lipid A, periplastic space, porin channel, RESISTANT to lysozyme and penicillin attack.
G+ , but seen best with Acid Fast stain?
Mycobacteria - TB and Leprosy
G- bacteria with addition phospholipid membrane to protect from immune recognition, with periplastic flagella
Spirochetes
