Experimental selection for ivermectin resistance in Ostertagia ostertagi in cattle.
Recent reports of suspected ivermectin (IVM) resistance in Ostertagia ostertagi have highlighted the need for research into the mechanisms of IVM resistance. However, there are no reports of resistant field isolates of O. ostertagi, which have been characterized for molecular research. Therefore, an anthelmintic susceptible O. ostertagi population was selected for IVM resistance by repeatedly e...
متن کاملInfection with the gastrointestinal nematode Ostertagia ostertagi in cattle affects mucus biosynthesis in the abomasum
The mucus layer in the gastrointestinal (GI) tract is considered to be the first line of defense to the external environment. Alteration in mucus components has been reported to occur during intestinal nematode infection in ruminants, but the role of mucus in response to abomasal parasites remains largely unclear. The aim of the current study was to analyze the effects of an Ostertagia ostertag...
متن کاملImproved methods for isolating DNA from Ostertagia ostertagi eggs in cattle feces.
A multiplex PCR assay for differentiating strongyle eggs from cattle has recently been described; however, the egg disruption and DNA extraction procedures, though effective, are inadequate for large studies or clinical application. The purpose of this research was to evaluate methods for disrupting trichostrongyle eggs, then assess commercial kits for extracting egg DNA using Ostertagia ostert...
متن کاملLocalized complement activation in the development of protective immunity against Ostertagia ostertagi infections in cattle.
The abomasal nematode Ostertagia ostertagi is a major causal agent contributing to production inefficiencies in the cattle industry in temperate regions of the world. Protective immunity to infections develops very slowly and resistance to reinfection manifests only after prolonged exposure. Mechanisms underlying the development of protective immunity remain largely unexplored. Immune animals, ...
