|
A woman presents to the ER with 6 presentations of TSS
What are they? |
1. Erythrematous rash
2. Vommiting 3. Hypotension 4. Fever 5. Diahhrea 6. Desquamating palms/soles |
|
|
|
What 9 conditions can Staph cause?
|
1. Bacteremia
2. UTI 3. Meningitis 4. Pneumonia 5. Septic Arthritis 6. Osteomyelitis 7. Sepsis 8. Skin infection 9. Acute endocarditis |
BUMP SOSSA

|
|
How do Staph evade the immune system
|
Protein A - prevents phagocytosis
Leukocidines- Destroy WBC Staph A has coagulase helps conceal bacteria from Immune System |
|
|
|
HOK antigens are associated with ehat bacteria
|
E-Coli
|
|
|
|
Which bacteria is constantly changing its antigen to avoid detection?
|
Shigella is constantly changing its H antigen to avoid detection
|
|
|
|
The H antigen in Shigella allows it ti avoid detection
T/F? |
False, shigellla has NO flagella therefore no H antigen.
Salmonella has an H antigen |
|
|
|
All E Coli are pathogenic
T/F? |
False, it is part of the normal flora. It is the plasmid or TRANSPOSON insertion that makes it pathogenic
|

|
Case: A 5 yr old ate a hamburger and developed renal failure with thrombocytopne and anemia
What could be the cause? |
Enterohemorrhagic E Coli
Primarily in cattle: beef and unpasteurized milk. It can cause Hemolytic Uremic Syndrome (HUS) in children <10 as well as diarrhea (shigella like toxin) |
|
|
|
50 year old woman visits Italy where she developes diarrhea,
What could be the cause- include molecular mechanism? |
ETEC- enterotoxic e-coli
HST and HLT are responsible No NaCl reabsorption Cl and HCO3 excreted carring all the water with it |
|
|
|
Which toxin binds the 60s ribosome preventing protein synthesis
What does this cause? |
EHEC- Shigella like toxin prevent protein synthesis Epithelium cant repair and causes bleeding in stool
|
|
|
|
What diseases are caused by E Coli?
|
Diarrhea, Neonatal meningitis, UTI and Sepsis
|
DUNS
|
|
|
Enterotoxin causes sepsis in E Coli
T/F? |
Flase, Lipid A which is an endotoxin leads to sepsis
|
|
|
|
Which of the following are true
Salmonella 1. Ferments lactose 2. Ferments glucose 3. Does not produce H2S 4. Has a K antigen 5. non-motile |
Salmonella
+ H2S + Lactose - Glucose - K antigen (has Vi) + Motile |
