The Paraneoptera (Hemipteroid Assemblage) comprises the orders Thysanoptera (thrips), Hemiptera (bugs), Phthiraptera (lice) and Psocoptera (booklice and barklice). The phylogenetic relationships among the Psocodea (Phthiraptera and Psocoptera), Thysanoptera and Hemiptera are unresolved, as are some relationships within the Psocodea. Here, we present phylogenetic hypotheses inferred from SSU rDN...

Interest in parasites of wildlife has increased significantly in recent years. Pleasingly, the role of wildlife as the source of emerging infectious diseases has been countered by reasoned and balanced responses from ecologists and conservationists concerned about the dearth of knowledge of the infectious agents harboured by wildlife, their impact on wildlife health, the factors, both natural a...

In the past decade, reverse genetics opened new ways to study gene expression in trypanosomes with the development of transient and stable transformation systems. Using stable integrative transformation, it is now possible to carry out precise gene replacements which facilitate the analysis of expression of multicopy gene families (Swindle et al. 1995). Since integration occurs at a low frequen...
