First report on the helminthfauna of the yellow-necked mouse, Apodemus flavicollis, in the Iberian Peninsula

2016

Summary Information about the prevalence of helminth parasites of the yellow-necked mouse, Apodemus flavicollis, in the Iberian Peninsula is almost non-existent and there is no reliable data reported from Spain. Fourteen A. flavicollis from the Erro River valley (Navarre, Spain) were examined for endoparasites, between February 2001 and July 2002. Thirteen specimens (92.9 %) of the total sample were parasitized by at least one of the following six helminth species: one trematode (Corrigia vitta), one cestode (Taenia parva larvae) and four nematodes (Trichuris muris, Calodium hepaticum, Heligmosomoides polygyrus and Syphacia stroma). This is the first report about the helminthfauna of A. fla…

Analysis of Water Quality of the Stobrawa River at the Location of the Walce Small Retention Reservoir

2018

Małe zbiorniki wodne spełniają funkcje gospodarcze, energetyczne, przyrodnicze, rekreacyjne i poprawiają bilans wodny. Budując zbiornik wodny, oprócz zagadnień ilościowych wody, należy także wziąć pod uwagę jakość wody, która będzie retencjonowana w zbiorniku. Często wykorzystaniu zbiornika, jak i jego istnieniu, mogą zagrozić zanieczyszczenia dopływające do niego głównie z wodą i rumowiskiem. Ważne są badania monitoringowe w zlewniach rzek na których zamierza się budować małe zbiorniki wodne, ponieważ w tych zlewniach najczęściej nie prowadzi się badań jakości wody. Bardzo ważnym problemem jest więc zanieczyszczenie zbiorników planowanych. Celem pracy jest analiza jakości wód rzeki Stobraw…

An arthritogenic alphavirus uses the α1β1 integrin collagen receptor

2005

Ross River (RR) virus is an alphavirus endemic to Australia and New Guinea and is the aetiological agent of epidemic polyarthritis or RR virus disease. Here we provide evidence that RR virus uses the collagen-binding alpha1beta1 integrin as a cellular receptor. Infection could be inhibited by collagen IV and antibodies specific for the beta1 and alpha1 integrin proteins, and fibroblasts from alpha1-integrin-/- mice were less efficiently infected than wild-type fibroblasts. Soluble alpha1beta1 integrin bound immobilized RR virus, and peptides representing the alpha1beta1 integrin binding-site on collagen IV inhibited virus binding to cells. We speculate that two highly conserved regions with…
