Microscopic alterations in Fasciola hepatica from sheep treated with albendazole

Abstract Currently, albendazole is one of the most commonly used drugs because of its affordability. The objective was to evaluate the histopathology of Fasciola hepatica specimens. For this, the efficacy test was performed on sheep treated with albendazole at the dose recommended for F. hepatica, in wh...

Anthelmintic resistance of injectable macrocyclic lactones in cattle: A systematic review and meta-analysis

Abstract The purpose of this work was to identify, critically assess, and summarize available data from primary research about the anthelmintic resistance of injectable macrocyclic lactones in cattle. Meta-analysis was performed to estimate the pooled Odds Ratio and 95% Confidence Intervals. Of the 1504...

The human infection is mainly due to the accidental intake of metacercariae present in watercress and/or contaminated water. The human disease is uncommon in Chile, despite the high prevalence of animal infection, which a...

Multiple anthelmintic resistance in Southern Brazil sheep flocks

Abstract Gastrointestinal parasites represent an important cause of reduced productivity of sheep worldwide. As anthelmintic are still the main control tool for these parasites, this work evaluated the efficacy of commercially available active principles in 22 sheep flocks in the southern region of Rio G...

Anthelmintic effect of thymol and thymol acetate on sheep gastrointestinal nematodes and their toxicity in mice

Abstract Thymol is a monoterpene and acetylation form of this compound can reduce the toxicity and enhance its biological effects. The objective of this study was to evaluate the effect of thymol and thymol acetate (TA) on egg, larva and adult Haemonchus contortus and the cuticular changes, acute toxicit...
