- 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.What populations of people are most affected by Listeria Monocytogenes illness or Listeriosis?Why is listeriosis a serious problem even with refrigerated foods?
- 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 vectorWhat foods are commonly implicated in cases of listeriosis?Which of these statements concerning the causative agent of listeriosis is false?a) It can cause meningitis during the first month of life.b) It is a Gram-positive rod that can grow in refrigerated food.c) It is usually transmitted by the respiratory route.d) Infection can result in bacteremia.e) It is widespread in natural waters and vegetation.
- If there is a causal relationship between the presence of H. pylori and ulcers, how might you explain that 50% of the patients with a normal endoscopic examination were infected with the bacteria?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 statements about listeriosis is false?(a) The causative agent, Listeria monocytogens, can befound in many types of food .(b) When pregnant women are infected with Listeria mono-cytogens, the bacteria may cause fetal damage or death.(c) Bacteriophages can be used to eliminate Listeria oncontaminated food.(d) Infection with Listeria monocytogens rarely results inmeningitis.(e) Listeria L-forms lack cell walls and are able to persistinside of macrophages after phagocytosis.
