What pathogenic bacteria causes Salmonella?
The pathogen that causes salmonella is salmonella enteriditis. The bacteria is larger than a virus; but, is visible to the eye with the microscope. It is rod-shaped, gram negative, non-motile bacteria that does not form spores. Interestingly enough it communicates to its fellow bacteria via AHL. It infects the cell, multiplies within it; then, bursts the cell. Special effector protein factors are required for salmonella intestinal invasion and the induction of fluid secretion and for inflammatory responses. The symptoms include diarrhea, headache, muscle aches, nausea, vomiting, fever, and abdominal cramps. The symptoms start 12-72 hours after introduction and may last 4-7 days. There is no vaccine because salmonella is causative. It is transferred by contaminated food/beverage or from feces (from unwashed hands). Fatality is ~1%.
