We have just passed the first decade of the 21th century without developing a confident vaccine against any parasitic disease affecting humans. This disappointed fact encourages us to do more in-depth research in order to know our enemies closer and in some moment reach the adequate solution for people that are suffering some of such infections and of course preventing these infections. However, nothing of aforementioned will be possible without research to develop knowledge that can be applied to find new drugs or vaccines. For this second special issue, we are inviting researchers worldwide to send papers including reviews as well as original research on different topics of distinct important parasitic diseases which can range from basic biology, genetics, and pathology to vaccine development as well as immune response against protozoa and helminth infections.

Special attention will be given to the current “omics” era to emphasize the use of microarrays and database software for genomic, transcriptomic, glycomic, and proteomic screening to search for a useful parasitological assay. In this second decade of this century, the number of molecular pathologic techniques will expand as additional disease-associated mutations are defined. Parasitic organisms remain the scourge of the developed and underdeveloped worlds; many of them still result in a large number of human deaths and sickness worldwide, while drug resistance remains as a major problem. Genome, transcriptome, and proteome projects involving parasitic organisms are now abundant, and technologies for the investigations of the parasite transcriptome and proteome are well established, whereas for glycomics, they are just in the beginning. There is no doubt the era of the “omics” is with parasitology, and current trends in the discipline are addressing fundamental biological questions that can make the best use of the new technologies. Thus, another primary aim of this special volume is to publish advances in the general area of parasite “omics” and to outline where the application of these technologies can impact the development of new control methods for parasitic diseases. The topics to be covered include, but are not limited to:

• Genomics, proteomics, and transcriptomics on protozoan parasites causatives of diseases in humans such as amebiasis, trypanosomiasis, toxoplasmosis, leishmaniasis, malaria, and giardiasis
• Genomics, proteomics, transcriptomics, and glycomics on helminths causatives of human infections such as schistosomiasis, cysticercosis, echinococcosis, filariasis, and toxocariasis
• Immune response to similar infections (using gene-deficient mouse models is very welcome)
• Coinfections helminth-helminth or helminth-protozoan reaching immunologic and susceptibility aspects are also welcome
