In healthy individuals, the bacteria usually leave the body through feces, as to not cause many health problems. 

Case Fatality Ratio

S. newport, with the other nontyphoidal salmonellosis is estimated to cause over 1 million cases of illness and 500 deaths. 

Incubation Period

Most Salmonella bacteria have an incubation period of 4 to 7 days.


A Gram negative, nonmotile, rod shaped bacteria. It is approximately 2-5 microns long.   

Enviromental Survival

It grows in a facultative anaerobic environment, so it can survive in a dry environment for weeks and many months in water. It is resistant to ampicillin, chloramphenicol, and streptomycin. 

Dose Response Models

Route: oral, Response: infection


\[P(response)=1-exp(-k\times dose)\]

Optimized parameters:
k = 3.97E-06
ID50 = 1.74E+05
