Question

QUESTION 12 Through the microscope, these bacteria appear as Gram-negative bacilli possessing a peritrichous arrangement of flagella. They typically infect the intestinal tract in humans and animals and are transmitted by the fecal oral route. People usually become infected from ingesting improperly refrigerated, uncooked or undercooked poultry, eges, meat, or dairy products contaminated with animal feces. While around 50,000 cases are reported annually in the U.S., most cases go unreported and it is estimated that over 2,000,000 people a year in the U.S. become infected with this bacterium and at least 500 die Symptoms generally appear 6- 48 hours after ingestion of the bacteria and include vomiting nausea, non-bloody diarrhea, fever, abdominal cramps, myalgias, and headache. Symptoms generally last from 2 days to 1 week followed by spontaneous resolution. Pseudomonas aeruginosa Helicobacter pylori Escherichia coli Salmonella species
