00:00 Infections of a GI continuum Pseudomembranous colitis is the complication of the bacteria, C. diff. Meaning to stay in a hospital setting, the patient was given antibiotics. All the competitors for C. diff were killed off. The bacteria that ends up on top of the mountain is your C. diff causing Pseudomembranous colitis. Diarrhea; fever; leukocytosis; complications you are worried about, megacolon and perforation. And so therefore colonoscopy shows pseudomembranes, your diagnosis based on toxin assay. The treatment for C. diff would in fact be oral vanco. Recurrence in 25% requires prolonged antibiotics for Clostridium difficile, is our topic. Let's get and take a look at that Pseudomembranous colitis and if you were to then take a look at the colon here, you would notice here that it looks like you are a pseudomembrane and it perhaps looks like also had a colitis in company but it's not, it's a pseudomembrane.
