Hookworms infect perhaps one-fifth of the entire human population, yet little is known about their interaction with our immune system. The two major species are Necator americanus, which is adapted to tropical conditions, and Ancylostoma duodenale, which predominates in more temperate zones. While having many common features, they also differ in several key aspects of their biology. Host immune...
A number of the micro-organisms are capable of producing polyhydroxyalkanoates (PHA’s) as storage food reserve under unbalanced growth conditions. The mechanical properties of PHA’s are similar to that of synthetic plastics like polyethylene, polypropylene etc. The advantage of using PHA’s over synthetic plastic is that PHA’s are completely mineralized into carbon dioxide and water through the ...
The transmission of puffy skin disease (PSD) to rainbow trout Oncorhynchus mykiss Walbaum was tested in the laboratory by conducting co-habitation challenges with puffy skin (PS)-affected fish (Trojans) collected from the field. Two separate challenges were conducted using Trojans sourced from two different sites and diploid (first trial) or triploid (second trial) naïve fish. PSD-specific clin...
The effect of polyparasite infections on cytokine and chemokine responses as well as the effect of antiparasite treatment was studied in children without parasite infection (the G0 group), in children singly infected with Schistosoma haematobium (the G1 group), and in children multiply infected with S. haematobium/Schistosoma mansoni, Entamoeba histolytica/Entamoeba dispar, and Necator american...
In traditional medicine, of Carica papaya (Caricacea) seeds are used as a coarse powder, in maceration or an aqueous decoction, for the management helminthiasis. With aim contributing to helminthiasis, this study set out develop syrup with anthelmintic properties based on L. The fluid extract was prepared and subjected phytochemical screening. A physicochemical microbiological stability control...
Co-infection with hookworm and schistosomes is a common phenomenon in sub-Saharan Africa, as well as in parts of South America and southeast Asia. As a first step towards understanding the metabolic response of a hookworm-schistosome co-infection in humans, we investigated the metabolic consequences of co-infection in an animal model, using a nuclear magnetic resonance (NMR)-based metabolic pro...
Grapevine powdery mildew, caused by the ascomycete Erysiphe necator, is a major threat to grapes worldwide. Despite its global impact on grape production, E. necator is sensitive to adverse environmental conditions, such as excess heat, free water and UV radiation. Using detached leaf co-culture assays, 3-d-old single colonies of E. necator were exposed to 1, 2 or 3 consecutive d of punctuated ...
