Lopment of AR in sheep gastrointestinal nematodes [15].five.six.7.eight.9.10.Conclusions The present situation of anthelmintic resistance in Uruguay is becoming aggravated using the early improvement of resistance to monepantel by Haemonchus spp. (putative Haemonchus contortus). Further molecular studies are necessary to recognize the mechanism of monepantel resistance, permitting early detection to develop tactics to prevent the spread of resistant wormspeting interests The authors declare that they have no competing interests. Authors’ contribution AEM and GEB have been responsible for FECRT method and ready the manuscript. ZR coordinated field activities at Farm 1 and supplied information on drug use. All authors study, revised and authorized the final manuscript. Acknowledgments We are quite grateful to field personnel from INIA Research Farms “SIRT1 Activator Purity & Documentation Glencoe” and La Estanzuela. We thank S. Pimentel, B. Carracelas and L. Moreno for laboratory work. We thank Dr. Paula Menzies for language editing and essential critique of the manuscript.
