Background: Anthelmintic drugs have been widely used in sheep as a cost-effective meansfor gastro-intestinal nematode (GIN) control. However, growing anthelmintic resistance(AHR) has created a compelling need to identify evidence-based management recommen-dations that reduce the risk of further development and impact of AHR.Objective: To identify, critically assess, and synthesize available data from primary researchon factors associated with AHR in sheep.Methods: Publications reporting original observational or experimental research on selectedfactors associated with AHR in sheep GINs and published after 1974, were identified throughtwo processes. Three electronic databases (PubMed, Agricola, CAB) and Web of Science (acollection of databases) were searched for potentially relevant publications. Additional pub-lications were identified through consultation with experts, manual search of referencesof included publications and conference proceedings, and information solicited from smallruminant practitioner list-serves. Two independent investigators screened abstracts for rel-evance. Relevant publications were assessed for risk of systematic bias. Where sufficientdata were available, random-effects Meta-Analyses (MAs) were performed to estimate thepooled Odds Ratio (OR) and 95% Confidence Intervals (CIs) of AHR for factors reported in?2 publications.Results: Of the 1712 abstracts screened for eligibility, 131 were deemed relevant for fullpublication review. Thirty publications describing 25 individual studies (15 observationalstudies, 7 challenge trials, and 3 controlled trials) were included in the qualitative synthesisand assessed for systematic bias. Unclear (i.e. not reported, or unable to assess) or high riskof selection bias and confounding bias was found in 93% (14/15) and 60% (9/15) of theobservational studies, respectively, while unclear risk of selection bias was identified in allof the trials. Ten independent studies were included in the quantitative synthesis, and MAswere performed for five factors. Only high frequency of treatment was a significant riskfactor (OR = 4.39; 95% CI = 1.59, 12.14), while the remaining 4 variables were marginallysignificant: mixed-species grazing (OR = 1.63; 95% CI = 0.66, 4.07); flock size (OR = 1.02; 95%CI = 0.97, 1.07); use of long-acting drug formulations (OR = 2.85; 95% CI = 0.79, 10.24); anddrench-and-shift pasture management (OR = 4.08; 95% CI = 0.75, 22.16).

Abstract:The purpose of this study was to estimate the acaricide susceptibility of Varroa destructor populations from Uruguay, which had never been exposed to synthetic acaricides. It was also to determine whether acaricide resistance to coumaphos occurred in apiaries in which acaricide rotation had been applied. Bioassays with acaricides against mite populations that had never been exposed to synthetic acaricides were performed, also against mite populations in which control failures with coumaphos had been reported. Additionally, coumaphos' effectiveness in honeybee colonies was experimentally tested. The lethal concentration that kills 50% of the exposed animals (LC(50)) for susceptible mite populations amounted to 0.15 ?g/Petri dish for coumaphos and to less than 0.3 ?g/Petri dish for the other acaricides. Coumaphos LC(50) was above 40 ?g/Petri dish for resistant mites. The effectiveness of coumaphos in honeybee colonies parasitized by V. destructor ranged from 17.6% to 93.9%. LC(50) for mite populations susceptible to the most commonly applied miticides was determined, and the first case of coumaphos resistance recorded in Uruguay was established. |
