Abstract
Salmonella enterica invade the host via the intestinal tract. There are ~ 2 thousand distinct serovars of non-typhoidal Salmonella (NTS) that can cause gastroenteritis in normal hosts, but bacteremia is an uncommon complication of gastroenteritis except at the extremes of age [1]. In contrast, enteric fever and invasive NTS infections (iNTS) are each caused by only a few serovars of S. enterica (Table 1), and bacteremia not gastroenteritis is their principal manifestation.
