This chapter presents the different techniques to purify the native forms of Fasciola hepatica fatty acid-binding protein (Fh12) using size exclusion chromatography and isoelectric focusing (IEF). Also, it presents the procedure to study the immunological effect of the purified protein Fh12 using monocyte-derived macrophages (MDM) obtained from healthy human donors. For this purpose, I present the procedure to isolate and culture peripheral blood mononuclear cells (PBMCs) to generate alternatively activated macrophages (AAMΦ) by in vitro exposure to Fh12.

Plasmin, the final product of fibrinolysis, is a broad-spectrum serine protease that degrades extracellular matrix (ECM) components, a function exploited by multiple pathogens for dissemination purposes. The trematode Fasciola hepatica is the leading cause of fasciolosis, a major disease of livestock and an emerging zoonosis in humans. Infection success depends on the ability of F.

Background: poses a considerable global public health challenge. In Egypt, approximately 60% of the inhabitants in the Northern and Eastern areas of the Nile Delta are affected by this parasite, whereas the Southern region experiences a significantly lower infection rate of 6%.
Aim: Construction of an immune phage display Nbs library based on the VHH framework for selecting -specific Nbs for seeking cost-effective, sensitive, and specific diagnostic tools for rapidly detecting mansoni.

The Northern Bolivian Altiplano is the fascioliasis endemic area where the highest prevalences and intensities in humans have been recorded. In this hyperendemic area of human fascioliasis, the disease is caused only by Fasciola hepatica and transmitted by Galba truncatula, the sole lymnaeid species present in the area. When analysing the link between global warning and the recently reported geographical spread of lymnaeid populations to out-border localities, a marked heterogeneous climatic change was found throughout the endemic area.

Mass ivermectin (IVM) treatment of livestock (MITL) is under consideration as a malaria control tool as IVM-treated livestock are lethal to blood-feeding Anopheles mosquitoes. MITL is routinely used as a prophylaxis in livestock to reduce the burden and transmission of helminth infections. Recently, there has been a shift in the veterinary IVM market in Southeast Asia wherein nearly all standard IVM formulations are now co-formulated with clorsulon (CLO).

Background: Fascioliasis represents one of the most significant parasitic and foodborne zoonotic diseases in the world. Resistance to currently deployed human and veterinary flukicides is a growing health problem. Zinc oxide nanoparticles (ZnO-NPs) have developed enormous importance in nanomedicine.
