Flashcards in Lecture 6 - Staphylococci Deck (23):
Looking through a microscopy, staph looks like...
A bunch of grapes
Two forms of staph
Coagulase + physical features and type of staph
Gold, staph aureus
Coagulase - type of staph
Epidermis and sarophyticus
Where does staph epidermidis colonize?
The skin, everyone has it
S. Aureus colonizes what species and where?
Humans and in the nose and on the skin
How is S. aureus spread?
What is the most common nosocomial infection?
S. aureus creates a distinct physical trait
Abscess full of neutrophils/puss located on the skin. These require drainage and antibiotics
How does staph kill WBCs?
Through the release of toxins (hemolysis) causing more wide spread and infection
Impetigo is most commonly found on who and with what physical features?
Children, pimple like (non-bullous) or fluid filled blisters (bulls)
Stye physical features
Infection around the eye causing swelling which eventually goes away on its own
Furuncle (BOIL) caused by
Infected hair folicle
Carbuncles caused by
Infection of many hair folicles
Infected bone marrow which is very challenging to treat
Infective endocarditis is...
Infected heart valves causing lesions
What causes Toxic Shock Syndrome (TSS)
What caused Menstural TSS
High absorbancy tampons
How do tampons cause Menstural TSS
By colonizing staph inside of the vagina and by changing the regulation of toxxins
What happens when a super antigen is formed?
T-cells become over activated causing inflammatory response, cytokine storm and shock/organ failure
What toxin is specific for the menstrual TSS?
