In order to assess the relation between @entity14454 and @entity293 (U.T.T.), a study of two villages in the surroundings of Niamey (Rep. of @entity3456 ) was undertaken. In the first village located near a @entity579 plantation irrigation scheme, the global prevalence of @entity4114 infection was 77%. @entity1 between 5 to 14 years of age were all infected and their mean egg output was 500 eggs/10 ml of urine. In the second village, where water is supplied from wells, @entity2040 was almost absent. @entity293 were diagnosed upon the cytologic count of the urinary sediment and the urine culture. Comparison between @entity4114 infected and non-infected villages showed that the prevalence of U.T.I. was 3.8 times higher among the females of the infected village. This was also noticed for old @entity1 and especially for @entity1 aged 5 to 14 (5.2% U.T.I.) for whom @entity293 is usually uncommon. However the mean blood pressure and the creatininemia showed no difference between the two populations. If @entity2040 increases the risk of chronic @entity2885 , that increase could not be accounted for with the measures of these two variables.
