A comparison between two in vitro techniques to detect resistance to ivermectin in field populations of Cooperia spp. in cattle
(University College Dublin, 2021)
Anthelmintic resistance in beef cattle production is a well-known worldwide problem, contributing to the economic losses caused by gastrointestinal nematodes. Resistance to ivermectin (IVM) is present in 93.5% of farms in ...
Immunological responses and cytokine gene expression analysis to Cooperia punctata infections in resistant and susceptible Nelore cattle
(Elsevier B.V., 2008-08-01)
Cellular and humoral immune response, as well as cytokine gene expression, was assessed in Nelore cattle with different degrees of resistance to Cooperia punctata natural infection. One hundred cattle (male, weaned, 11-12 ...

The use of nemabiome metabarcoding to explore gastro-intestinal nematode species diversity and anthelmintic treatment effectiveness in beef calves
(Elsevier B.V., 2017-11-01)
Next-generation deep amplicon sequencing, or metabarcoding, has revolutionized the study of microbial communities in humans, animals and the environment. However, such approaches have yet to be applied to parasitic helminth ...
