In order to aid the development of new approaches to schistosomiasis control, changes were analyzed in prevalence at the county level in the State of Bahia from the 1950s to the 1990s, as were determinants and the effect of community-based chemotherapy. In general, no substantial changes were observed in the basic pattern of spatial distribution of the prevalence of infection. However, during t...

OBJECTIVE To predict the subnational spatial variation in the number of people infected with Schistosoma haematobium in Burkina Faso, Mali and the Niger prior to national control programmes. METHODS We used field survey data sets covering a contiguous area 2750 x 850 km and including 26,790 school-age children (5-14 years old) in 418 schools. The prevalence of high- and low-intensity infectio...

The aim of this study was to analyze the limits and possibilities of the Information System in the Schistosomiasis Control Program (SISPCE) for characterization and surveillance of the disease at the local level. The data were aggregated to calculate epidemiological indicators such as the program's coverage and intensity of mansoni schistosomiasis infection in the endemic municipalities (counti...

BACKGROUND Questionnaires of reported blood in urine (BIU) distributed through the existing school system provide a rapid and reliable method to classify schools according to the prevalence of Schistosoma haematobium, thereby helping in the targeting of schistosomiasis control. However, not all schools return questionnaires and it is unclear whether treatment is warranted in such schools. This ...

After three successive treatments with oxamniquine the continuing elimination of Schistosoma mansoni eggs was observed in patients, who came from various regions of Brazil, with different clinical forms of schistosomiasis. The objective of the present study was to determine the experimental behaviour of five different S. mansoni isolates in Swiss Webster mice that were submitted to treatment wi...

A study was carried out in Santo Antonio de Jesus, a town in Bahia State, north-east Brazil, to determine the relationship between various biological, socioeconomic, behavioural, and geographical factors and the prevalence and intensity of Schistosoma mansoni infection. The town's population was around 45,000 and the study was targeted at all children born in 1970-71 who were living in the town...

Abstract Background Schistosomiasis is a common helminthic infection in the tropics and subtropics, particularly sub-Saharan African countries including Ethiopia. In these counties, Schistosoma mansoni significant public health problem due to risk of reinfection recurrent disease despite implementing several rounds preventive chemotherapy. This systematic review meta-analysis aimed at assessing...

The relationship between bladder tumors and Schistosoma haematobium is well known, but only sporadic cases of bladder infection due to Schistosoma mansoni have been reported. In this case, a 48-year-old woman with macroscopic hematuria, dysuria and a palpable abdominal mass was investigated. Ultrasound showed a large exophytic mass in the bladder. Transurethral resection of the bladder revealed...

Experimental hepatic schistosomiasis was produced in CBA mice using a local strain of S. mansoni. A comparative study of the hepatic concentrations of cytochrome P-450 and microsomal protein in the control and infected animals was carried out. S. mansoni infection significantly (P less than 0.05) reduced the liver cytochrome P-450 and microsomal protein. This suggests impairment of drug metabol...

Abdel Wahab et al. (1979) were the first to report the ultrasound features of hepatosplenic schistosomiasis mansoni. Their findings were confirmed by several investigators in Africa (Fataar et al. 1984, Hussain et al. 1984) and in Brazil (Cerri et al. 1984, Domingues et al. 1993, Pinto-Silva et al. 1994, Lambertucci et al. 2001, 2008). Table I summarises the main findings reported by the above ...
