Allelic frequency variations at the MDH-1 locus within Schistosoma mansoni strains from Guadeloupe (French West Indies): ecological interpretation.
1. An isoenzymatic study on Schistosoma mansoni from Guadeloupe has been carried out using isoelectric focusing in polyacrylamide gels. 2. Among the seven systems examined (LDH, MDH, G6PD, PGI, PGM, AcP, HK), only MDH showed variation at the MDH-1 locus and mdh-1a allele frequencies were used to characterise eight strains derived either from human or murine hosts, and representative of differen...
متن کاملAn ecological field study of the water-rat Nectomys squamipes as a wild reservoir indicator of Schistosoma mansoni transmission in an endemic area.
Small mammals are found naturally infected by Schistosoma mansoni, becoming a confounding factor for control programs of schistosomiasis in endemic areas. The aims of this study were: to investigate the infection rates by S. mansoni on the water-rat Nectomys squamipes during four years in endemic areas of Sumidouro, state of Rio de Janeiro, using mark-recapture technique; to compare two diagnos...
متن کاملUltrastructural alterations in adult Schistosoma mansoni caused by artemether.
Progress has been made over the last decade with the development and clinical use of artemether as an agent against major human schistosome parasites. The tegument has been identified as a key target of artemether, implying detailed studies on ultrastructural damage induced by this compound. We performed a temporal examination, employing a transmission electron microscope to assess the pattern ...
متن کاملAntioxidant effects of gold nanoparticles on Schistosoma mansoni induced granuloma, in vitro
Objective(s): Schistosomiasis and hepatitis C virus [HCV] co-infection is common among the Egyptian population. Co-infected patients have higher rate of chronic hepatitis, cirrhosis and hepatocellular carcinoma. The aim of the present study was to investigate the potential role of gold nanoparticles on granuloma in vitro. Materials and Methods: In the current study, granulocytes were isolated f...
متن کاملExperimental evidence and ecological perspectives for the adaptation of Schistosoma mansoni Sambon, 1907 (Digenea: Schistosomatidae) to a wild host, the water-rat, Nectomys squamipes Brants, 1827 (Rodentia: Sigmodontinae).
Due to the semi aquatic habits and the overlap of the geographical distribution of the water-rat, Nectomys spp., with schistosomiasis endemic areas, these wild rodents are very likely to acquire Schistosoma mansoni infection in their daily activities. The role of the water-rat in the S. mansoni cycle would be substantiated if one could prove that these rodents acquire the parasite during their ...
