Extinction risk is linked to lifestyle in freshwater gastropods

Diversity and Distributions, Volume 27, Issue 12, Page 2357-2368, December 2021., 2021
Abstract Aim Freshwater ecosystems and their biota are severely endangered by global change today, and predicted extinction levels are skyrocketing for many taxa. Most studies have focused on entire clades, while approaches testing for selective extinction risk with respect to ecological traits are rare. As studies are typically based on modern faunas,

Accurate and rapid detection of Fasciola hepatica copro‐DNA in sheep using loop‐mediated isothermal amplification (LAMP) technique

Veterinary Medicine and Science, Volume 7, Issue 4, Page 1316-1324, July 2021., 2021
The liver flukes F. hepatica and F. gigantica are agents for fasciolosis that is a zoonotic parasitic disease. Bennett and Ijpelaar (Journal of Agriculture Economy, 2005, 56, 135) estimated that F. hepatica causes annual economic loss by£40.4 million in the UK cattle industry.

Parasitic causes of meat and organs in cattle at four slaughterhouses in Sistan‐Baluchestan Province, Southeastern Iran between 2008 and 2016

Veterinary Medicine and Science, Volume 7, Issue 4, Page 1230-1236, July 2021., 2021
Among the organs examined for the existence of parasitic lesions, 64,497 livers (7.5%), 31,401 lungs (3.6%) and the carcasses of 1,171 cattle (0.13%) were discarded due to parasitic infections. The main parasitic lesions detected in the condemned livers were attributed to Echinococcus granulosus (4.2%), Fasciola hepatica (3.1%) and Dicrocoelium ...

Heterobilharzia americana infection in dogs: A retrospective study of 60 cases (2010‐2019)

Journal of Veterinary Internal Medicine, Volume 35, Issue 3, Page 1361-1367, May/June 2021., 2021
Abstract Background The trematode Heterobilharzia americana (HA) causes granulomatous gastrointestinal and hepatic disease in dogs. Before 2008, diagnosis relied on saline fecal sedimentation or histopathology, and earlier reports primarily described dogs with advanced disease or cases diagnosed incidentally at necropsy.

Efficacy of a low‐dose praziquantel and fenbendazole protocol in the treatment of asymptomatic schistosomiasis in dogs

Journal of Veterinary Internal Medicine, Volume 35, Issue 3, Page 1368-1375, May/June 2021., 2021
Abstract Background Established treatment protocols for schistosomiasis (Heterobilharzia americana) in dogs are expensive. Anecdotal reports suggest that lower doses of praziquantel, combined with fenbendazole, may eliminate asymptomatic infections.

Human fascioliasis in Argentina: retrospective overview, critical analysis and baseline for future research

Parasites & Vectors, 2011
In Argentina, human fascioliasis has never been adequately analysed, although having a physiography, climate, animal prevalences and lymnaeids similar to those of countries where the disease is endemic such as Bolivia, Peru and Chile.

Phylogenetic analysis of Lymnaeid snails based on 18S rDNA sequences [PDF]

Molecular Biology and Evolution, 1997
The 18S rDNA sequences of the six most common European Lymnaeidae species (Mollusca:Gastropoda:Basommatophora) have been obtained by direct PCR cycle sequencing and silver staining methods. The sequence alignment and secondary structures of the 18S rRNA gene of Lymnaea stagnalis, L. auricularia, L. peregra, L. palustris, L. glabra, and L.
