Question

Quizplus · Accepted Answer

Salmonella and Shigella are both facultative intracellular pathogens, meaning they are capable of living and replicating within host cells. They are not Gram-positive rods, nor do they produce shiga toxin. Salmonella can cause typhoid fever, but Shigella does not. Both bacteria are resistant to gastric acid, which allows them to survive passage through the stomach and cause infection in the intestines.
