Of 54 patients infected with Schistosoma haematobium, 65%, 49%, and 47% remained urinary carriers of Salmonella typhi and S. paratyphi A infections 3, 6, and 12 months, respectively, after initial diagnosis of bacillary enteric fever. Of 21 patients with typhoid or paratyphoid-A fever but no schistosomiasis, none became urinary carriers. The chronic enteric urinary carriers among the schistosomal patients had a high incidence of radiologically detectable obstructive lesions of the urinary tract (90% of 21 patients at 12 months) in contrast to the non-carriers among the schistosomal patients (none of 11). The incidence of the urinary carrier state was 51% in paratyphoid-A cases and 10% in typhoid cases, and was higher in children than in adults. Schistosomal lesions of the urinary tract appear to predispose toward the development of the urinary carrier state of the bacillary infections, and this suggests that effective therapy of the carrier condition may require surgical removal of the urinary obstructions in such cases and indicates the value of schistosomiasis-control measures in the prevention of acute and chronic salmonellosis.
