Structural and fucnctional aspects of diversity of Parasites(protozoa/helmithes/nematode)

Introduction

The purpose of this review was to summarize the current state of knowledge on the role of hybridization and evolution introgressii in ecology and parasites. We confine ourselves to the consideration of protozoa and helminths (such as nematodes, platyhelminths) parasites of animals, but sometimes use different systems to illustrate concepts that were not examined among animal. To highlight some of the original idea of hybridization and parasite-host interaction, we will begin with a brief summary of the host of hybridization. Then we discuss the lateral Gene/genome transfer between distant relatives taxa and parasites. In the last part of the review, we noted the evidence of hybridisation between closely related species of parasites, dispersed population or clonal lines, and then select the ecological importance or phenotypic characteristics of parasite hybrids (Seehausen 2004).

Nematode

Among animal parasites we know only one study, which examined the parasite population genetics through a host of hybrid zone. This study was not among the phylogenetic structure nematode parasite hybrid and purely parental stocks two kinds of shrew. We believe that future studies host hybrid fitness must begin to account for potential enigmatic parasite genetic structure. In the majority of filarial nematodes (Onchocercidae) mutualisticesk interaction seems to have evolved to obligate intracellular bacteria of wolbachia. Normal development and fertility nematode Genes 2010 1 105 parasite associated with Wolbachia infection. In addition, some strains of wolbachia in filarial nematode genome were reduced. Compared with Drosophila MELANOGASTER genome vol'bahii from the genome of wolbachia from filarial Brugia malayi nematodes. Gene loss allegedly occurred genes associated with the cell wall that may reflect biogeneza mutualisticesk relations of their interaction. Conversely, support of wolbachia genes associated with metabolic functions such as riboflavin and ...
