Treatment of the animals with avermectin compounds did not result in satisfactory EPG reduction in any herd. These results show that phenolic-substituted drugs have limited applicability in the studied cattle herds.
Phenolic-substituted compounds disophenol and nitroxynil showed differing efficacy.

Nitroxynil was effective against Haemonchus spp. Effectiveness evaluation of several cattle anthelmintics via the fecal egg count reduction test. The broad detection of parasite resistance to several anthelmintics recognized as good quality commercial drugs suggests that parasite populations have developed resistance to the main classes of 201 drugs available in Brazil.
Abstract Gastrointestinal nematodes resistant to anthelmintics have been reported in several regions of Brazil, and they may be associated with economic losses for the cattle industry. anialpec
Improving liveweight gain of lambs infected by multidrug-resistant nematodes using a FECRT-based schedule of treatments. Therefore, previous knowledge regarding parasite resistance was used as a tool to inform the choice of potentially efficacious combinations of drugs.
Anthelmintic resistance impact on tropical beef cattle productivity: Conflicts of interest The authors of this manuscript have no financial or personal relationships with other people or organizations that could inappropriately influence or anualpc the anuaplec of the paper. Articles from International Journal for Parasitology: Ten farms located in Rio Grande do Sul state were selected by: Acceptable efficacy was shown by some combinations: Drug resistance mechanisms in helminths: Other compounds are eventually used when the farmer suspects that conventional drugs are failing.
Additionally, the following technical criteria were considered: However, in the present study, with the exception of Oesophagostomum spp.
The resistance of Cooperia spp. Estimating the cost of subclinical parasitism in grazing ewes. Anthelmintic combination Genera Cooperia spp.
This article has been cited by other articles in PMC. Some of the two-drug combinations were effective against nematode populations identified as resistant to the anuapec compounds when used as single drugs. July ; 25 7: The use of combinations of two anthelmintic compounds with good efficacy as single drugs could be an effective means of delaying the development of drug resistance in parasites. On each farm, pre-treatment and post-treatment EPG counts were used to calculate the efficacy of each treatment based on the reduction in EPG.
Some strains of Oesophagostumum spp. 20122 incubation, larvae xnualpec recovered by baermanization, after which third-stage larvae in each culture were identified by genera following the criteria described by Van Wyk and Mayhew Diagnostic of the control and sensitivity profile of nematodes from sheep to albendazole and levamisole in northern Minas Gerais, Brazil.
In the farms evaluated here, no detailed information was obtained regarding the history of each drug at each farm because of a lack of available data. Each of the ten groups was randomly treated with a single drug in the first part of this study.

The effect of previous cold storage on the subsequent recovery of infective third stage nematode larvae from sheep faeces. The results of this study showed the presence of gastrointestinal nematodes resistant to the main commercially available anthelmintic drugs on cattle farms evaluated in the state of Rio Grande do Sul, Brazil. National Center for Biotechnology InformationU. Open in a separate window.
Anthelmintic treatment In the first part of the study, ten commercially available anthelmintic compounds were tested on each farm.
