A positive Widal's reaction developed in a 2-year-old girl following nontyphoid Salmonella gastroenteritis. Recent data from the Center for Disease Control suggest that false-positive Widal reactions following certain nontyphoid Salmonella infections may occur commonly. Antigens common to Salmonella groups A, B, and D account for this cross-reacting antibody.
