Which toxins are the major causes of Staph Scalded skin syndrome?
exfoliative toxin A and B
General mechanisms of transmission (review)
aerosol, direct contact, sexual contact, vectors, fecal:Oral (water), food, endogenous, nosocomial

what usually causes the rose-shaped spots of the petechial rash?
blood vessel damage in gram-negative infections
What is a purple rash due to blood leaving the blood vessels called?
What is a floor burn-like rash that eventually becomes a black scab called?
Which type of rash may be associated with menstrual TSS?
what type of rash is associated with chickenpox?
what type of rash may be seen with staphylococcal impetigo?
What type of rash is associated with a cutaneous anthrax infection?
What is a primary pathogen?
A microbe that, when present in the host, typically causes illness
What is an opportunistic pathogen?
Often normal flora microbe that causes illness when the host is immune compromised.
What are the four types of primary pathogens?
exotoxemia, invasive extracellular, exotoxemia + invasive extracellular, invasive intracellular
Tetanus, Diphtheria, Cholera, TSS,Scarlet Fever fall into which category of primary pathogen?
Haemophilus influenzae, Streptococcuspneumoniae, Neisseria meningitidis fall into which category of primary pathogen?
Staphylococcus aureus, Streptococcus pyogenes fall into which category of primary pathogen?
exotoxemia + invasive extracellular
Mycobacterium tuberculosis, Salmonella typhi, Listeria monocytogenes fall into which category of primary pathogen?
What are examples of the major categories exotoxins (review)?
ADP ribosylating enzymes, depurinating enzymes, cytolysins/cytotoxins, proteases, superantigens
T/F: Many exotoxins are referred to as A:B or B:B toxins, where A=active and B=host cell binding.
Where are many exotoxins encoded?
bacteriophages, plasmids, or pathogenicity islands
