【 摘 要 】

In the Subúrbio Ferroviário region of Salvador (Bahia, Brasil) occurrences of schistosomiasis were found. This fact motivated the investigation of the prevalence of the eggs in a group of 268 resident students in one of its neighborhoods (São Bartolomeu). The parasitological test analyzed by the Kato-Katz methodology, showed positive results in 30.2% of the children, ranging from 24 to 2,160 eggsSchistosoma mansoni/gram of feces. Infection was predominant in boys and in those 10 years old and over. Observation revealed that infection predominated in children that live close to natural water bodies. This region was where the three registered cases of hepatosplenicos occurred. Moreover, all the 81 children infected with Schistosoma mansoni eggs were born and live in the study area. Since this neighborhood presents all the elements of the epidemiological chain of Schistosoma mansoni, the evidences strongly suggests the urban transmission of this infection.
