Q

The systemic phase of Salmonella is usually abbreviated SP12 and usually results in general symptoms. Where as the intestinal phase of Salmonella is usually abbreviated SPI1 and uses T3SS needle to inject effector proteins in enterocytes allowing uptake of Salmonella into the enterocyte resulting in cell lysis, diarrhea, and intestinal damage. (Bovine)

True or False ?

A

True

Note: Infected with contaminated feed either through injestion (lleum or large intestine) or inhaled.
Intestinal phase is usually more virulent
