- All of the following pertain to listeriosis, except 1) intrauterine infection usually results in fetal death. 2) enterotoxin of the organism causes symptoms. 3) it causes a serious septicemia and meningitis in the elderly, immunocompromised, and infants. U 4) it causes symptoms of fever, diarrhea, and sore throat. 5) adequate pasteurization and thorough cooking of food can improve prevention.A parent calls to ask about giving a medication for diarrhea to his child, 12 years of age, who is recovering from the flu. The nurse expects the prescriber to recommend which medication? a) bismuth subsalicylate (Pepto-Bismol)b )Lactobacillus GG (Culturelle)c )belladonna alkaloid/phenobarbital combination (Donnatal Elixir)d) loperamide (Imodium A-D)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.
- Which of the following is not applicable to Listeria monocytogenes, or to the disease it causes, listeriosis? A) O most people with healthy immune systems are not affected by it, or show only mild symptoms of disease B) Ot can grow at refrigeration temperature C) O it is a facultative intracellular pathogen D) O polymerization of actin on its cell surface allow it to move E) O listeriosis is typically transmitted by an insect vectorThis pathogen is usuall foodborne and causes a mostly asymptomic disease.
