desmosome a circular, dense body that forms the site of attachment between certain epithelial cells, especially those of stratified epithelium of the epidermis, which consist of local differentiations of the apposing cell membranes.
-Exfoliatin
A staphylococcus toxin - Cleaves the desmosomes in the stratum granulosum - Separates layers of skin. - Example: Scalded skin syndrome (occurs more often in infants)
Scale of Infectious Dose def: the AMOUNT of pathogen (ie NUMBER of organisms) required for cause infection in a host.

So, Lysteria rhymes with Hysteria, and when I think of hysteria I think of someone dancing Hysterically…..(actually, me dancing hysterically..)
I also googled Hysteria, and found this:
HYSTERIA RADIO!
So here it goes: “Lysteria dances to Hysteria Radio”
If I don’t come up with all these silly associations my brain melts and confuses all the freakin bacterias, so bear with me…
