The success of the helminth-host relationship depends on a biochemical molecular arsenal. Perhaps the proteome is the largest and most important set of this weaponry, in which the proteins have a crucial role in vital processes to the parasite/host relationship, from basic metabolism and energy production to complex immune responses. Nowadays, the bioproducts expressed by the parasites are unde...

The information on mortality from echinococcosis is important not only for a better understanding of the severity of the disease, but also for evaluating the effectiveness of public health interventions. The aim of this research was to study the causes of mortality from echinococcosis. We have collected and analyzed the materials of 1,470 patients in 10 age - groups in the Republic of Armenia (...

The contributions of Brazilian physicians to knowledge of diseases caused by parasitic worms, during the second half of the nineteenth century, had distinct effects on three epistemic communities: Brazilian clinical anatomy, French medical geography, and the emerging field of medical parasitology. Accepting the heterogeneity of both the systems for legitimizing scientific facts and the epistemo...

A longitudinal study design was employed to collect Stomoxys flies between January, 2010 and December, 2011 from three different agro ecological settings, Sebeta, Debre Zeit and Fentale Districts, Ethiopia using vavoua traps. The study on the trapped Stomoxys flies was carried out with the aims of identification of Stomoxys species and comparison of the distribution, seasonality and relative ab...

This issue of the Journal of Helminthology includes a special topic dealing with six reviews on various aspects of parasitic helminths in Latin America and the Caribbean (LAC). The majority refer to helminths infecting aquatic hosts and range from fundamental questions to epidemiology and control challenges. Helminth infections are highly prevalent over large areas of LAC, where they cause seve...
