To the Editor:
Blood cultures with a short interval in the same day were associated with isolation of Salmonella typhi and Salmonella paratyphi A in a traveler with enteric fever. 1 Irrespective of the incidence of such dual infections, infection by S paratyphi A and Salmonella paratyphi B would require attention by practitioners of travel medicine. During 2004 to 2005, there was a sudden rise in the occurrence of S paratyphi A in Kolkata, India. The longitudinal community‐based study pointed to a 1.5 times higher isolation rate for S paratyphi A in comparison with S typhi. 2
Marine environment has been branded as a potential natural source of systematic variant of S paratyphi B and might be an important source for its acquisition. From 1998 onward, shellfish and human isolates of S paratyphi B from humans and shellfish in Galicia, Northwest Span, were systemic variants during phenotypic and genetic investigations. 3 Consumption of shellfish during travel to popular sea resorts might materialize as an impending risk for S paratyphi B enteric fever.
