Bacteria - word association Flashcards
AV nodal block
Lyme disease
MALT lymphoma
H. pylori
also gastric adenocarcinoma
Clue cell
Gardnerella vaginalis
Argyll Robertson pupil
Tertiary syphilis
Lacks classic peptidoglycan wall rendering B-lactam antibiotics less effectiove
Chlamydia trachomatis
Exotoxin A
Strep pyogenes
Produces alpha toxin
C. perfringes
Cleave SNARE protein
tetanospasmin
botulinum toxin
Mulberry molars
Congenital syphilis
Strawberry tongue, sandpaper rash
Scarlet fever - strep pyogenes (GAS)
Lymphgranuloma venereum
Chlamydia trachomatis serotype L1, L2, L3
Only bacterium with polypeptide capsule
Bacillus anthracis
Jarisch-Herxheimer reaction
post-antibiotic flu-like syndrome due to killed spirochetes releasing endotoxin
Q fever
Coxiella
cattle/sheep amniotic fluid
Cause oral/facial defects with sinus tracts
Actinomyces
Armadillo reservoir
Mycobacterium leprae
Gas gangrene and hemolysis
C. perfringens
Grows in 42C
Campylobacter jejuni
Avian reservoir
Chlamydia psittaci
Bilateral facial palsy
Lyme disease
Alcoholics, diabetics, aspiration
Kleb
Condyloma lata
Secondary syph
Important association with S. bovis
Colon cancer
Actin rocket tails
Listeria
Toxin A vs Toxin B in C. diff
Toxin A - binds to brush border of gut
Toxin B - cytotoxin - pseudomembranous colitis
Hansen disease with low cell-mediated immune response
Mostly Th2 response
Lepromatous
Tuberculoid has Th1, cell-mediated immune response
Obligate intracellular - cannot make own ATP
Chlamydia
Other obligate intracellular bacteria:
Rickettsia
Coxiella
Mycobacterium leprae
Contributes to chronic pneumonia in CF patients
Pseudomonas
due to mucoid polysaccharide capsule - biofilm formation
Cord factor
Mycobacterium
inhibits macrophage maturation
Affects Renshaw cells in spinal cord
C. tetani - tetanospasmin
