How Do People Contract Salmonella Poisoning

How do people contract salmonella poisoning?

A) The microbe can survive the acidic environment of the stomach and resist lysosomal degradation in macrophages.
B) The chemotactic messengers released by the salmonella bacterium do not attract sufficient neutrophils to entirely destroy the infection.
C) There is a delay in selection of the population of eosinophils that recognize and are responsible for fighting these bacterial infections.
D) The bacterium releases chemical messengers that make it resistant to phagocytosis.
E) The combination of foods eaten at the meal reduces the pH of the stomach sufficiently so that the bacterium was not destroyed.
