BACKGROUND The debilitating human disease schistosomiasis is caused by infection with schistosome parasites that maintain a complex lifecycle alternating between definitive (human) and intermediate (snail) hosts. While much is known about how the definitive host responds to schistosome infection, there is comparably less information available describing the snail's response to infection. METH...
Plant-derived molluscicides have been indicated as selective and low-cost strategies for the control of Biomphalaria glabrata (Say, 1818), an intermediate host schistosomes. This study aimed to evaluate aqueous ethanolic extracts leaves plants present in Cerrado such Caryocar brasiliense Camb., Ximenia americana L., Piptadenia viridiflora (Kunth) Benth., Schinopsis brasiliensis Engl. alternativ...
This review examines the recent high performance thin layer chromatography (HPTLC) literature on the effects of biotic and abiotic factors on certain analytes in the medically important freshwater snail, Biomphalaria glabrata. The analytes studied were lipids, lipophilic pigments, amino acids, and carbohydrates. As determined by HPTLC, various factors, such as larval parasitism, estivation, tem...
The intermediate hosts of Schistosoma mansoni, in Brazil, Biomphalaria glabrata, B. tenagophila and B. straminea, were identified by restriction fragment length polymorphism analysis of the mitochondrial gene cytochrome oxidase I (COI). We performed digestions with two enzymes (AluI and RsaI), previously selected, based on sequences available in Genbank. The profiles obtained with RsaI showed t...
The global increase in antibiotic use has led to contamination of freshwater environments. Despite the identified impacts antibiotics on humans and wildlife, effect host–parasite life cycles is relatively unexplored. In current study, we utilize trematode parasite Schistosoma mansoni, its snail intermediate host, Biomphalaria glabrata, investigate influence an ecologically relevant concentratio...
The objective of this work is to evaluate the action original Roundup® on snail Biomphalaria glabrata infected and not by Schistosoma mansoni observing its mortality reproductive biology. Snails were submitted for 30 days aqueous solutions Roundup at concentrations 0.1, 0.09, 0.08, 0.07, 0.06, 0.05, 0.04, 0.03, 0.02, 0.018, 0.016, 0.014, 0.012 0.01 (%) determine LC50. To analyze activity B. gla...
