Q

In the case of generalized salmonellosis, the agent has to be isolated from the faces

A

F

Salmonella can be shed in feces, particularly during gastrointestinal infection, in cases of systemic or generalized salmonellosis where the bacteria have spread beyond the gastrointestinal tract, isolation from feces might not always occur. Instead, the bacteria may be isolated from blood, tissues, or other relevant sites of infection.
