[Salmonella paratyphi A urinary infection in Schistosoma mansoni bilharziasis].

The authors report a case of urinary tract infection caused by Salmonella paratyphi A in a patient with Schistosoma mansoni bilharziasis and describe the symbiotic relationship between these two micro-organisms. The association was not fortuitous: schistosomes behave as reservoirs of bacteria and can cause bacterial discharges followed by a long carrying period.
