Secretory glands in cercaria of the neuropathogenic schistosome Trichobilharzia regenti - ultrastructural characterization, 3-D modelling, volume and pH estimations [PDF]
Background Cercariae of schistosomes employ bioactive molecules for penetration into their hosts. These are released from specialized unicellular glands upon stimuli from host skin.

Multi-host helminth systems are difficult to study at a population level due to inherent spatial and temporal sampling challenges. Consequently, our understanding of the factors affecting gene flow, genetic drift and effective population size is limited.

Schistosomiasis prevalence in swamplands of North-eastern Brazil is complicated by the presence of alternative hosts, such as the marsh rat Holochilus brasiliensis . However, the effects of Schistosoma mansoni on this host – at both individual and population levels - are unknown. We investigated the pathological effects of S.

Background. Schistosomiasis is a parasitic disease that resides in the vascular system of vertebrates, causing a chronic, debilitating disease that affects more than 200 million people and 800,000 deaths per year in over 70 countries. This parasite causes liver dysfunction and disorders normal hematological and biochemical profiles in addition to ...

Identification of a major causative agent of human cercarial dermatitis, Trichobilharzia franki (Muller and Kimmig 1994), in southern England and its evolutionary relationships with other European populations. [PDF]
Background Trichobilharzia is the most species rich and widely distributed genus of schistosomes and is known throughout Europe and North America as an agent of human cercarial dermatitis. The disease is caused by an acute allergic reaction in the skin

Can the studies at a spatial scale of 100s meters detect the spatiotemporal fluctuations of a parasite assemblage? [PDF]
The importance of small-scale heterogeneity in local factors which overrides that of larger-scales factors, suggest that local factors play a major role in determining the richness and prevalence of larval digeneans in intertidal gastropods.

Quantum Non-Objectivity from Performativity of Quantum Phenomena [PDF]
We analyze the logical foundations of quantum mechanics (QM) by stressing non-objectivity of quantum observables which is a consequence of the absence of logical atoms in QM.
