Associations of production characteristics with the on-farm presence of < i > Fasciola hepatica < /i > in dairy cows vary across production levels and indicate differences between breeds
by Andreas W. Oehm, Yury Zablotski, Martina Hoedemaker, Amely Campe, Christina Strube, Daniela Jordan, Andrea Springer, Markus Klawitter, Gabriela Knubben-SchweizerFasciola hepatica is one of the economically most important endoparasites in cattle production. The aim of the present work was to evaluate the relevance of production level on the associations of on-farm presence ofF.hepatica with farm-level milk yield, milk fat, and milk protein in Holstein cows, a specialised dairy breed, and in Simmental cows, a dual purpose breed. Furthermore, we investigated whether differential associations were present depending on breed...

Fasciola hepatica soluble antigens (FhAg) induce ovine PMN innate immune reactions and NET formation in vitro and in vivo
Vet Res. 2023 Nov 12;54(1):105. doi: 10.1186/s13567-023-01236-z.ABSTRACTFasciola hepatica causes liver fluke disease, a worldwide neglected and re-emerging zoonotic disease, leading to hepatitis in humans and livestock. In the pathogenesis, flukes actively migrate through liver parenchyma provoking tissue damage. Here, parasites must confront leukocytes of the innate immune system in vivo. Polymorphonuclear neutrophils (PMN) are the most abundant granulocytes and first ones arriving at infection sites. PMN may display neutrophil extracellular traps (NETs), consisting of nuclear DNA, decorated with histones, enzymes, and an...

Abundance, Distribution, and Diversity of Freshwater Snail and Prevalences of Their Infection by Cercaria of < em > Fasciola gigantica < /em > and < em > Schistosoma < /em > spp at Mayo-Vreck River, Far North Region of Cameroon
J Trop Med. 2023 Oct 20;2023:9527349. doi: 10.1155/2023/9527349. eCollection 2023.ABSTRACTMalacological and parasitological studies were conducted from April 2020 to March 2021 to determine the abundance and distribution of molluscs and cercariae of Schistosoma spp and Fasciola gigantica. Collected molluscs are exposed to strong light to induce cercarial release. Mollusc densities were higher at station 1 (Gamak) than in station 8 (Patakai), with Bellamya unicolor and Biomphalaria pfeifferi more abundant and Bulinus truncatus, B. tropicus, and B. globosus less abundant. The overall prevalence of cercariae (19.87%) is highe...

Assessment of Fasciola and Paramphistomes co-infection in large ruminants through faecal egg counts around Taiping, Malaysia
Trop Biomed. 2023 Sep 1;40(3):344-350. doi: 10.47665/tb.40.3.011.ABSTRACTEmerging cases of Fasciola and Paramphistomes co-infection have been reported, especially in tropical regions. Thisis due to Fasciola and Paramphistomes sharing biological factors which influence the pattern of transmission, especially in faecal egg shedding due to interaction and competition in the definitive host. Most reports surveyed the occurrence of fasciolosis in ruminants with a lack of observation of faecal egg distribution. Therefore, present study is aimed to assess the distribution of Fasciola and Paramphistomes faecal egg count (fec) in c...
