View Sketchy Micro.pdf from BIO 101 at Alabama A&M University. saprophyticus can be differentiated from another coagulase-negative staphylococcus by its resistance to Novobiocin. One of the exotoxins is encoded on the bacterial chromosome, while the other is encoded on a plasmid. aureus and cause detachment within the epidermal layer, by breaking down the desmosomes.
In this video the narrator mentions that Staph aureus can cause toxic shock syndrome in the classic situation of prolonged tampon use via the production of a toxin called TSST-1 that binds MHC II and T cell receptors which leads to shock. A complicated infection typically involves a patient that is immunocompromised, elderly, male, pregnant, diabetic, and/or with urologic abnormalities such as indwelling catheters or kidney disease.
