Nontyphoidal Salmonella Infections
Diseases caused by nontyphoidalSalmonellaspecies
EachSalmonellaserotype can cause any or all of the clinical syndromes described below, although given serotypes tend to produce specific syndromes. Enteric fever, for instance, is caused byS. Paratyphitypes A, B, and C. An asymptomatic carrier state may also occur. However, carriers are rare and do not appear to play a major role in large outbreaks of nontyphoidal gastroenteritis. Persistent shedding of organisms in the stool for≥1 year occurs in only 0.2 to 0.6% of patients with nontyphoidalSalmonellainfections.
