Unraveling the microRNAs Involved in Fasciolosis: Master Regulators of the Host-Parasite Crosstalk.

Fasciolosis is a neglected tropical disease caused by helminth parasites of the genus spp., including () and (), being a major zoonotic problem of human and animal health. Its control with antihelminthics is becoming ineffective due to the increase in parasite resistance.

Megaoesophagus associated to inflammatory infiltrate in the autonomous plexus in a 7-year-old Spanish Water Dog.

Background: Megaoesophagus (ME), a disorder of the oesophagus characterized by diffuse oesophageal dilation and decreased peristalsis that may be congenital or acquired. Knowledge regarding the aetiology and prognosis for canine acquired ME is currently limited with most cases being idiopathic, which is a considerable problem to implement an appropriate treatment and a potential better prognosis.

Case Presentation: A 7-year-old, neutered, female Spanish Water Dog was evaluated for progressive weight loss, chronic vomiting and regurgitation.

Advancement in Diagnosis, Treatment, and Vaccines against : A Comprehensive Review.

In this review article, we aim to provide an overview of fasciolosis in ruminants. Diagnosis through new coprological methods (such as Flukefinder, FLOTAC, and Mini-FLOTAC) remains the most suitable approach for farms. Regarding treatment, there is a scarcity of available drugs, and resistance to them has prompted new approaches (including drug combinations, enhanced metabolism, or the use of natural compounds) to address this issue.

Liver Histopathological and Immunohistochemical Evaluation from Experimentally Infected and Reinfected Sheep.

Fasciolosis is an important economic disease of livestock. There is a global interest in the development of protective vaccines since the current anthelmintic therapy is no longer sustainable. A better knowledge of the host-parasite interaction is needed to design effective vaccines.

Evaluation of Th1/Th2, regulatory cytokines and transcriptional factor FoxP3 in sheep immunized with a partially protective and non-protective vaccine and challenged with Fasciola hepatica.

Gene expression for Th1/Th2 cytokines (IL-4 and IFN-ɣ), regulatory cytokines (TGF-β and IL-10) and the transcriptional factor FoxP3 was analyzed in the liver and hepatic lymph nodes (HLN) from sheep immunized with partially protective and non-protective vaccine candidates and challenged with Fasciola hepatica. FoxP3 T cells were also evaluated by immunohistochemistry (IHQ). The most remarkable difference between the partially protected vaccinated (V1) group and the non-protected vaccinated (V2) group was a more severe expansion of FoxP3 T cells recorded by IHQ in both the liver and HLN of the V2 group as compared to the V1 group, whereas no differences were found between the V2 group and the infected control (IC) group.
