What causes the symptoms of staphylococcal food
poisoning? Why are cases of staph food poisoning often
linked to a food preparer?
Step by step
Solved in 2 steps
- Identify the causative agent of staphylococcal food poisoning and explain the method for transmission of the bacteria to food sources. Describe the characteristics of the staphylococcal toxin.Identify the food sources of Listeria monocytogenesinfections. How does Listeria evade the immune system?Define the term pyogenic, what is this term referring to?
- What is the possible role of the axostyle in the pathogenesis of trich?This pathogen is usuall foodborne and causes a mostly asymptomic disease. The most common foods associated with it are deli meats and unpasteurized dairy products. It rarely cause meningitis and spsis. It is mainly of concern because it can lead to still birth. This pathogen is a) Stahylococcus aureus b) Streptococci pneumoniae c) Listeria monocytogens d) Streptocpccus pyogenesWhy do only certain strains of Staphylococcus aureus cause scalded skin syndrome?
- Knowing that most are caused by E. coli , why can cranberry be used to prevent UTIs?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.Describe the function of the major virulence factors expressed by Listeria monocytogenes that are important in invasion and cell to cell spread. thank you!
