In this book we discussed the urinary tract infections caused by trematodes, certainly Schistosoma haematobium which is transmitted through penetration of skin by forked tail cercaria which present in polluted water and that caused by bacterial infections. We concentrate our efforts to know the prevalence of bacterial and Schistosoma haematobium co-infection among school children in villages southern to Shendi, River Nile state, Sudan. We try to give clear pictures about the prevalence of urinary tract infections caused due to association of bacterial strains and Schistosoma haematobium between children selected in this study and also we identify the antimicrobial agents to that's pathogens. We hope to introduce real science to all Microbiology and parasitology students in the world.
