    Talk about Toxicogenic Bacterial Diarrhea. So we're going to walk into a little bit more detail here. Where you have watery diarrhea but please note that the feces does not contain leukocytes, WBC–free. <i>Staph. aureus</i>, it's so ridiculously quick within 6 hours Mayo, mayonnaise, at room temperature, don't ever do that. Put your mayo back in the fridge. Also egg products, so these are obviously, well, refers to mayo. And we talked about potato salad which also has the mayo in it. That's the common denominator. <i>Clostridium perfringens</i>, here, rewarming of precooked food, "Church Picnic Diarrhea" <i>E. coli,</i> Traveler's Diarrhea, plasmid mediated and rehydration absolutely required and maybe perhaps your Cotrimethoxazole, the combination of Sulfamethoxazole and Trimethoprim. With <i>E. coli</i> remember there's a huge range. If it's <i>E. coli</i> 0157:H7 that then brings about undercooked beef and you're thinking about your hemolytic−uremic syndrome in that young child, correct? Or if it's <i>E. coli</i> and you're dealing with what's known as ST and LT. And that's the one in which it is heat–stabile in which it's ST and that ST is going to be dealing with your cyclic GMP. Whereas if it's LT, and that's dealing with cyclic AMP. And those are things that you paid attention to early on in Micro. It might be a good time for you to make sure that you're completely clear with different types of <i>E. coli</i>. ETEC, EHEC, <i>E. coli </i>0157:H7. <i>Vibrio cholera</i>, once again, this is a good one for you to review for sure. And here, we talked about this being a secretory type of diarrhea. Here, common denominator for all of these organisms, no fecal leukocyte and diarrhea is watery. Continue discussion with no fecal leukocytes would be <i>Bacillus</i>. When we talked about the rice that's been reheated, also tacos; doesn't...
