“…The organic farms, since they use a lower number of treatments, may then present higher species diversity, preserving the chance to be infected by rarer species. This was shown in meat sheep when 7 conventional farms were compared to 5 organic ones [11]. Conventional farms had higher proportions of a few species: (1) Nematodirus and Cooperia (two farms), (2) Haemonchus and Chabertia (two farms), or (3) Teladorsagia circumcincta and Trichostrongylus in the abomasum (two farms) whereas organic farms harboured all the species in balanced proportions.…”

“…Many adaptations are required in the most diverse (from breeds to products) European meat cattle production conditions (intensive, extensive lowland or mountain meat production). The meat sheep farms we presented [11,38] use preventive (changing of pasture between the seasons, delayed turn-out, use of aftermath), diluting (mixed grazing with less susceptible host of the same species-ewes) or evasive (change of pastures within the season) strategies. They do not rely on mixed or alternate grazing (one of the diluting strategies).…”

“…more species are well represented. A decrease in helminth diversity could be related to increasing anthelmintic treatments in dairy-goats [52], in sheep [11] and in meat cattle (Costa, personal communication, 2001). We also noted from Swedish cattle data [18] that cattle treated with boluses (continuous release of anthelmintics) have one or two species whereas untreated cattle harbour three species.…”

-The use of anthelmintics is strongly limited in organic farming. This may induce a change in the intensity (no of worms) and diversity (proportions of species) of helminth infection. Helminths remain a major preoccupation in organic sheep farming: high levels of infection have been recorded on several farms and helminth diversity is always higher. The helminth infection in milk cattle of northern Europe is controlled and diversity is higher in organic farms, as recorded in sheep. The role of helminth diversity on intensity is still unclear. Grazing management is one of the means to controlling helminths. The use of safe pastures for calves and sheep after weaning is one of the major components of control. The use of alternate or mixed grazing is common for cattle in northern countries but is uncommon for sheep in France. Grazing management is not sufficient to controlling infection in sheep and conventional anthelmintic treatments are performed. Additionally, alternative treatments are used. The alternative therapies based on phytotherapy or homeopathy are largely recommended in organic farming but do not have any demonstrated efficacy. More research is needed to evaluate such therapies. ruminant organic farm / helminth / grazing management / anthelmintic / phytotherapyRésumé -Gestion des helminthes de ruminants en agriculture biologique. L'emploi des anthelminthiques est fortement limité en élevage biologique. Cette diminution de leur utilisation peut conduire à des changements en ce qui concerne l'intensité (nombre de vers) et la diversité (proportion des espèces) des parasites. Les helminthes sont une préoccupation majeure en élevage biologique ovin : les infestations sont très fortes dans certaines fermes et la diversité est plus élevée que dans les élevages conventionnels. L'infestation des bovins laitiers par les helminthes dans les pays du nord de l'Europe est assez bien contrôlée et la diversité est plus forte également en élevage biologique. Le rôle de la diversité sur l'intensité n'est pas encore clair. La gestion des pâturages est l'un des moyens de contrôler l'infestation. L'utilisation de pâtures saines pour les veaux ou les agneaux après le sevrage est l'une des composantes essentielles de la gestion des parasites. L'utilisation de pâturage alterné ou mixte avec des espèces différentes est commun dans les régions nordiques pour les bovins mais n'est 625

A real-time PCR approach to identify anthelmintic-resistant nematodes in sheep farms

et al. 2017

Resistance to fenbendazole, ivermectin, and moxidectin was explored by a fecal egg count reduction test in four meat sheep flocks in southwestern France where anthelmintic resistance was suspected. The FECR test results of the present study confirmed the presence of benzimidazole resistance in three out of the four farms and the presence of ivermectin resistance in one flock. In addition, a suspicion of moxidectin resistance was shown in this latter farm. Both conventional morphological and molecular identifications were performed on larval cultures before and after the treatment in the studied farms. A high positive correlation was found between the number of larvae counted under binocular microscope and the number of larvae estimated by the qPCR analysis (R 2 = 0.88) and a high Cohen's Kappa value (0.91) in the detection of strongylid larvae in larval cultures. According to qPCR results, Trichostrongylus species demonstrated high levels of BZ resistance and Teladorsagia circumcincta was involved in the IVM resistance in one farm. The molecular procedures used in this study have the potential to be beneficial for anthelmintic resistance surveillance in sheep industry.
