Salmonella Infection and Prevention

What are some common consequences of a large-scale Salmonella infection event?

• Increased agricultural output and lower food prices.

• Thousands of people falling ill, product recalls, and legal action against industry leaders.

• Improved public health awareness and new vaccine development.

• A temporary decrease in egg consumption followed by a rapid recovery.

Which of the following are common symptoms of Salmonella infection?

• Headache, muscle aches, and skin rash.

• Fever, stomach cramps, and diarrhea.

• Nausea, vomiting, and blurred vision.

• Joint pain, fatigue, and shortness of breath.

How can Salmonella bacteria spread to eggs from an infected chicken?

• Through direct contact with other infected chickens only.

• By spreading through the developing yolk or contaminating the eggshell via feces.

• Only if the chicken is visibly sick and laying discolored eggs.

• Through airborne particles in the chicken coop.

How does Salmonella survive the acidic conditions of the human stomach?

• It rapidly multiplies to overwhelm the acid.

• It produces acid shock proteins that shield it from damage.

• It forms a protective cyst that acid cannot penetrate.

• It changes its genetic makeup to become acid-resistant.

What specialized system does Salmonella use to inject effector proteins into intestinal cells?

• A flagellum-like structure for propulsion.

• A needle and syringe-like system.

• A complex enzyme secretion pathway.

• A direct absorption mechanism through cell walls.

What is the body's immediate response when intestinal cells are breached by Salmonella?

• The cells immediately self-destruct to prevent spread.

• They release cytokines to prompt the immune system into action.

• They absorb more water to flush out the bacteria.

• They create a protective barrier to encapsulate the bacteria.

What is a key characteristic of S. Typhi, the bacteria that causes typhoid fever?

• It primarily infects chickens and is spread through eggs.

• It is a common strain that causes mild food poisoning.

• It spreads from person to person, mainly via poor sanitation and untreated drinking water.

• It is easily treated with over-the-counter medications.

Which of the following is a recommended practice to prevent Salmonella infection?

• Consuming raw cookie dough and unpasteurized milk.

• Washing hands, avoiding unpasteurized milk, and thoroughly cooking meat and eggs.

• Eating only organic produce and avoiding all animal products.

• Relying solely on antibiotics for prevention.
