Chapter 7, Problem 2CAE

Between March 9 and April 12,five chronic peritoneal dialysis patients at one hospital became infected with Pseudomonas aeruginosa. Four patients developed peritonitis (inflammation of the abdominal cavity), and one developed a skin infection at the catheter insertion site. All patients with peritonitis had low-grade fever, cloudy peritoneal fluid, and abdominal pain. All patients had permanent indwelling peritoneal catheters, which the nurse wiped with gauze that had been soaked with an iodophor solution each time the catheter was connected to or disconnected from the machine tubing. Aliquots of the iodophor were transferred from stock bottles to small in-use bottles. Cultures from the dialysate concentrate and the internal areas of the dialysis machines were negative; iodophor from a small in-use plastic container yielded a pure culture of P. aeruginosa.

What improper technique led to this infection?

Three to five days after eating Thanksgiving dinner at a restaurant, 112 people developed fever and gastroenteritis. The dinner consisted of Roast Turkey, turkey giblet soup, mashed potatoes and crushed giblet gravy. The gravy was not refrigerated and was served the entire Thanksgiving day. The analysis of leftover food showed the same bacteria as was isolated from patients. a) What was the source of illness? b) What was the most likely microbe causing this illness? c) Was this an infection or an intoxication?
Why does Helicobacter pylori cause ulceractions in the lining of the Stomach? 1)The microbes secrete a toxin that prevents the host from detecting invasion of the microbe and thus allows it to thrive in the stomach and damage the host cells. 2)After invasion of the microbe in the cells lining the stomach, they are no longer able to produce mucous to protect the host cells from acid erosion 3)The microbe produces an enzyme that causes the cell to produce potent digestive enzymes that erode the stomach lining. 4)Once the microbe has entered the stomach, it releases digestive enzymes that degrade the mucous secreting cells.
A patient in ICU with an indwelling medical device is presenting with invasive infection symptoms, specifically fever and chills. They have been on a course of antibiotics that has not alleviated the condition. a) What type of organism do you suspect is causing the infection and why?
