Biological Rhythm Research, 1997
Circadian rhythms in the emergence of S. mansoni cercariae from Biomphalaria tenagophila and B. glabrata, snail hosts of schistosomosis in Brazil, were investigated. A total of 35 specimens of B. tenagophila (Sao Paulo, Brazil) and 12 B. glabrata (Minas Gerais, Brazil) exposed individually to five miracidia of Schistosoma mansoni originated from the ...

Eosinophilic meningoencephalitis is an endemic zoonosis in Southeast Asia and the Pacific Islands, but in recent years, new cases have been reported in various countries outside these regions, including Brazil, where it is considered an emerging disease. In this study, the effect of infection by the nematode Angiostrongylus cantonensis, one of the main

Agglutinins and hemolysins fromBiomphalaria tenagophila snails
Experientia, 1980A saline anti-A and incomplete anti-A,B agglutinin were found in spawn extracts of Biomphalaria tenagophila snails. Significance differences after papain and pronase treatments were also found for A1 and A2 subgroups. The hemolysin titers are high, and unspecific.

Experiments to determine the susceptibility of Biomphalaria tenagophila from 20 localities over the species range exposed to a strain of Schistosoma mansoni showed widely varying infection rates, from 0% to 91.5%, this latter having been observed in a sample from an area where the natural infection rate of B.

Concomitant infection with different parasites may be a helpful laboratorial strategy leading to the better understanding of the mechanisms used by the internal defense system (IDS) of Gastropoda to deal with helminth infection, such as Schistosoma mansoni. This work reports the effect of co-infection of Angiostrongylus vasorum and S.

Resistance to Schistosoma mansoni by transplantation of APO Biomphalaria tenagophila
Parasite Immunology, 2006SUMMARY Transplantation of the haematopoietic organ from Biomphalaria tenagophila (Taim strain, RS, Brazil), resistant to Schistosoma mansoni, to a highly susceptible strain (Cabo Frio, RJ, Brazil) of the same species, showed in the recipient snails resistance against the trematode, when a successful transplant occurred.

Endosulfan (END) is an insecticide used in agriculture and as a wood preservative. Since END is practically insoluble in water, ethanol (ETOH) is often employed as a carrier solvent to spike it in the test medium in aquatic toxicity assays. In this study were investigated the effects of END and ETOH on the reproduction of the freshwater snail ...
