Wildlife-transmitted Taenia and Versteria cysticercosis and coenurosis in humans and other primates
Publication date: Available online 11 April 2019Source: International Journal for Parasitology: Parasites and WildlifeAuthor(s): Peter Deplazes, Ramon M. Eichenberger, Felix GrimmAbstractWild mustelids and canids are definitive hosts of Taenia and Versteria spp. while rodents act as natural intermediate hosts. Rarely, larval stages of these parasites can cause seriouszoonoses. In Europe, four cases of Taenia martis cysticercosis have been diagnosed in immunocompetent women, and two cases in zoo primates since 2013. In North America, a zoonotic genotype related but distinct from Versteria mustelae has been identified in 201...

Cryptosporidium spp. in wild rats (Rattus spp.) from the Hainan Province, China: Molecular detection, species/genotype identification and implications for public health
In this study, we analyzed the occurrence and genetics of Cryptosporidium in wild rats from Hainan, China. From December 2017 to October 2018, 150 wild rats were captured and fresh fecal material was collected from intestinal sections. Rat species were identified by PCR-based amplification and analysis of the vertebrate cytochrome b (cytb) gene. Cryptosporidium was examined by PCR amplification of the partial small subunit of ribosomal DNA (SSU rDNA). C. viatorum were subtyped by PCR analysis of the gp60 gene. A total of four rat species were identified including Asian house rats (Rattus tanezumi) (n = 46), brown rats ...

Cysticercosis by Taenia pisiformis in brown hare (Lepus europaeus) in northern Italy: epidemiologic and pathologic features
Publication date: Available online 10 April 2019Source: International Journal for Parasitology: Parasites and WildlifeAuthor(s): Laura Stancampiano, Silvia Ravagnan, Gioia Capelli, Gianfranco MiliternoAbstractIn Northern Italy, a hastening of hare population decline was noticeable from 2008. In the same year hunters reported a sudden increase of hares infected by Taenia sp. larvae, whose morphology was consistent with T. pisiformis cysticerci. The aim of the survey was: i)to identify the parasites through morphological features and molecular techniques; ii)to quantify the prevalence and abundance of cysticerci in hunted ha...

There and back again – The return of the nasal mite Halarachne halichoeri to seals in German waters
Publication date: Available online 11 April 2019Source: International Journal for Parasitology: Parasites and WildlifeAuthor(s): Anja Reckendorf, Peter Wohlsein, Jan Lakemeyer, Iben Stokholm, Vivica von Vietinghoff, Kristina LehnertAbstractThe nasal mite Halarachne halichoeri (Acari; Halarachnidae) is adapted to live in the marine environment with pinnipeds as its primary host and can cause different levels of upper respiratory disease in both harbour seals (Phoca vitulina) and grey seals (Halichoerus grypus). Historical reports of H. halichoeri occurring in seals from German waters date back to the end of the 19th century...

Molecular phylogeny provides new insights on the taxonomy and composition of Lyperosomum Looss, 1899 (Digenea, Dicrocoeliidae) and related genera
We present the molecular analyses based on novel sequences of nuclear and mitochondrial genes obtained from 56 isolates of adult flukes and larval stages of dicrocoeliids belonging to Lyperosomum, Skrjabinus, Zonorchis as well as previously available sequence data. According to obtained results we propose to return Zonorchis clathratus and Z. petiolatus into Lyperosomum, and to recognize L. alagesi as a synonym of L. petiolatum. Our study shows that L. petiolatum commonly occurs in Europe in corvids as well as in several species of migratory songbirds, e.g. Sylvia atricapilla. At the same time, the Turdidae appear to host ...
