Assessment of the experimental infection by Echinostoma paraensei (Lie & Basch, 1967) (Trematoda: Echinostomatidae) in two Biomphalaria tenagophila (D’Orbigny, 1835) (Gastropoda: Planorbidae) isolates resistant and susceptible to Schistosoma mansoni (Sambon, 1907) (Trematoda: Schistosomatidae)

Biotemas, 2017
Different isolates of Biomphalaria tenagophila show a large spectrum of compatibility to the trematode Schistosoma mansoni, ranging from entirely refractory to highly susceptible. The aim of this study was to verify the pattern of compatibility of two B.

Morphological characterization of the hemocytes of the pulmonate snail Biomphalaria tenagophila [PDF]

Memórias do Instituto Oswaldo Cruz, 1993
The blood cells of the pulmonate snail Biomphalaria tenagophila, an important transmitter of the trematode Schistosoma mansoni in Brazil, were examined by light and transmission electron microscopy (TEM). Two hemocyte types were identified: hyalinocytes and granulocytes. Hyalinocytes are small young (immature), poorly spreading cells, which have a high

Evaluation of Toxic, Cytotoxic, Mutagenic, and Antimutagenic Activities of Natural and Technical Cashew Nut Shell Liquids Using the Allium cepa and Artemia salina Bioassays

BioMed Research International, Volume 2015, Issue 1, 2015., 2015
The cashew nut releases a substance that is known as cashew nut shell liquid (CNSL). There are both natural (iCNSL) and technical (tCNSL) cashew nut shell liquids. This study used an Artemia salina bioassay to evaluate the toxic effects of iCNSL and tCNSL cashew nut shell liquids.

Genetic Variation between Biomphalaria alexandrina Snails Susceptible and Resistant to Schistosoma mansoni Infection

BioMed Research International, Volume 2013, Issue 1, 2013., 2013
Much effort has been made to control schistosomiasis infection in Egypt. However, enduring effects from such strategies have not yet been achieved. In this study, we sought to determine the genetic variability related to the interaction between Biomphalaria alexandrina snails and Schistosoma mansoni.

Interaction between primary and secondary sporocysts of Schistosoma mansoni and the internal defence system of Biomphalaria resistant and susceptible to the parasite

Memorias do Instituto Oswaldo Cruz, 2011
The outcome of the interaction between Biomphalaria and Schistosoma mansoni depends on the response of the host internal defence system (IDS) and the escape mechanisms of the parasite.

A Shift from Cellular to Humoral Responses Contributes to Innate Immune Memory in the Vector Snail Biomphalaria glabrata [PDF]

, 2016
International audienceDiscoveries made over the past ten years have provided evidence that invertebrate anti-parasitic responses may be primed in a sustainable manner, leading to the failure of a secondary encounter with the same pathogen.
