“…Biomphalaria spp. are not passive hosts for trematodes, since they possess an internal system that can recognize, manage, and eliminate pathogens (Adema et al 1994a(Adema et al , b, 2000Loker and Adema 1995;Ataev and Coustau 1999;Coustau et al 2009 (Ataev et al 1997(Ataev et al , 1998. E. paraensei can develop in B. glabrata and Physa rivalis, but infection of Biomphalaria straminea was unsuccessful .…”

“…A particular species of the genus Biomphalaria may be nonsusceptible by providing an unsuitable environment. However, even if a snail species offers the right environment, its defence system can recognize and eliminate the parasite (Van der Knaap and Loker 1990;Lardans and Dissous 1998;Adema et al 2000;Coustau et al 2009). The success of an echinostome infection in B. glabrata depends largely on the immunobiological interactions between the snail and the parasite.…”

This chapter examines the most salient literature on the development of nonschistosome larval digeneans in Biomphalaria spp. (members of the superfamilies Clinostomoidea, Diplostomoidea, Echinostomatoidea, Paramphistomoidea, and Pronocephaloidea). For this purpose, the general biology of the nonschistosome trematode species that use Biomphalaria spp. as intermediate hosts are analyzed.Thereafter, the main features of these parasitic infections are studied with particular emphasis on topics such as the effect of the infections on the snail, the antagonism and/or competition between different digenean species in the snail, the immunology of the infection, and the genomic and proteomic aspects of these host-parasite interactions.

“…L'un des atouts de ces parasites est qu'ils provoquent chez les mollusques résistants une réponse beaucoup plus forte que ne le fait S. mansoni et qu'ils exercent, chez les individus sensibles, une immunosuppression ou une immunomodulation propice à l'étude des cibles immunitaires du mollusque [7,8]. Des travaux initiés dans les années 1990 par l'équipe de E.S.…”

“…Des analyses protéomiques ont également été menées pour identifier les différences d'expression de protéines hémocytaires ou plasmatiques selon que les individus sont susceptibles ou résistants [22,23]. L'ensemble de ces travaux a permis d'identifier une multitude de gènes, potentiellement importants pour la réponse immunitaire, et appartenant à différentes catégories fonctionnelles telles que des gènes codant des protéines de reconnaissance, d'adhérence entre cellules, ou entre les cellules et la matrice, des protéines antimicrobiennes, des protéines impliquées dans le stress oxydant ou la détoxification du stress oxydant (Figure 3) (voir [8]). Parmi les candidats les plus inattendus figurent deux potentiels régulateurs de l'immunité similaires à des cytokines de vertébrés, le MIF, macrophage migration inhibitory factor, et AIF, ou allograft inflammatory factor [14], dont l'analyse fonctionnelle est actuellement en cours.…”

“…Les réponses d'encapsulation de B. glabrata vis-à-vis de S. mansoni ou de E. caproni ne semblent pas associées aux mêmes modifications d'expression génique. Le suivi de l'expression de plusieurs gènes d'intérêt immunitaire chez des individus sensibles et résistants, après infection par ces deux parasites, a en effet montré des différences significatives : on observe globalement une stabilité du taux de transcrits chez les individus exposés à S. mansoni, qu'ils soient sensibles ou résistants, alors que chez les individus exposés à E. caproni, seuls les résistants présen-tent une forte augmentation de l'expression de ces gènes candidats [8]. De même, l'échantillonnage des transcriptomes de B. glabrata après stimulations (challenge) immunitaires suggère que les réponses dirigées contre les bactéries Gram positif et Gram négatif sont identiques entre elles, mais diffèrent d'une réponse à l'infection par S. mansoni [29].…”

Snails of the genus Biomphalaria are of significant medical importance with many species living in freshwater habitats associated with human settlements; many of these snail species are obligate intermediate hosts of the human blood fluke S. mansoni, the causative agent of hepatosplenic schistosomiasis. This parasitic disease continues to disrupt the lives of about 200 million people in over 70 countries and prevents these individuals from otherwise reasonable expectations of healthy and productive lives. Furthermore, it is estimated that within the developing world, especially in sub-Saharan Africa, more than 700 million people are at risk of becoming infected, despite the efforts to control transmission in human and snail populations by mass chemotherapy and the use of molluscicides. Several factors, such as the absence of a schistosome vaccine, the recent appearance of resistance to antischistosome drugs, and human activities that expand snail habitats, have increased the need for a better understanding of schistosome-snail interactions. In recent years, the application of new technologies has contributed to the accumulation of considerable new information on this topic that may be of great use to biomedical scientists.In addition to the impact of Biomphalaria spp. on public health, these snails are also interesting models for the study of other topics such as population biology, including genetics and demography, proteomics, invertebrate immunobiology, mating systems, and biogeography, among others. Biomphalaria spp. snails have been extensively used as experimental biological models contributing significantly to new developments in many areas studied by biomedical scientists. Extensive coverage of these topics is included in this book, also considering trematode species other than schistosomes.The aim of the present book is to provide an overview of the recent advances in the Biomphalaria spp.-larval trematode interactions, especially in Biomphalariaschistosome systems. Emphasis is placed on gaps in our knowledge that must be filled to gain a better understanding of the relationships in these host-parasite systems. This may be critical for a deeper knowledge of the transmission of schistosomiasis and other snail-borne parasitic diseases. Pref...
