Salmonella bacterial poisoning can be initiated when
A) the microbe survives the acidic environment of the stomach and resists lysosomal degradation in macrophages.
B) the chemotactic messengers released by the microbe 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 fight these microbes.
D) the microbes release chemical messengers that make them resistant to phagocytosis.
E) The combination of foods eaten at the meal reduces the pH of the stomach sufficiently so that ingested microbes are not destroyed.
