Spore Forming Flashcards
Non motile, aerobic, spore forming
Bacillus
Rods in chains with square ends and spore at the center
Bacillus sp
Anaerobic, motile (f), toxin mediated
Clostridium
1st dse attributed to a bacterium
B anthracis
1st bacterial disease prevented by vaccination
B anthracis
This sp shows no hemolysis
B anthracis
C tetani
C botulinum
This sp shows hemolysis
B cereus
C perfringens
Liquifies gelatin
Bacillus
C tetani causes systemic invasion
False. Localized
C tetani causes the s/sx
No, toxin mediated
Mode of migration of tetanospasmin
Retrograde migration
What enzyme does tetanospamin degrades that prevents docking of vesicles
Synaptobrevin
What produces tetanospamin
Vegetative c tetani
What nts does tetanospamin block
Gaba and glycine
True or false. Small amount of tetanospasmin is not lethal. Requires large amount.
False
Target of tetanospasmin
Anterior horn cells
BS
What aids in spore germination and toxin prod
Low redox potential
Calcium salts
Necrotic tissue
Asso pyogenic infxns
Tetanus has CNS manifestations like altered LOC
None, fully conscious
Trismus
Contraction of jaw muscles
Risus sardonicus
Contraction of facial muscle
Test to check for trismus and risus
Spatula test
Cod in tetanus
Respi muscle arrest
IP for tetanus
4-5 days even weeks (jawetz)
average 14 (lecture)
Strychnine poisoning
Used for ddx in tetanus
Antimicrobials for tetanus
Pen G
Metro
What organism has their spore centrally located
Bacillus
The’re spores are usually larger than the rod itself. Located terminally
Clostridium
Most powerful neurotoxin
Botulinum toxin
Affects primarily the cranial nerves thus PNS
Botulinum toxin
Proteolysis of SNARE proteins
Synaptobrevin
Syntaxin
Snap 25
Botulinum toxin
