Bacteriuria in urinary schistosomiasis in Egypt a prevalence survey.

An epidemiologic survey to assess the prevalence of bacteriuria in urinary schistosomiasis was carried out in a region endemic for urinary schistosomiasis in Egypt. Twenty of 390 (5.1%) school boys aged 5--16 years were bacteriuric. This prevalence rate is more than 10 times greater than that found in comparable surveys in areas non-endemic for urinary schistosomiasis. In this endemic population bacteriuria was found in 6.5% of active egg excreters and 2.3% of non-egg excreters.
