Abstract
The aims of the present study were: (a) to describe the prevalence of helminth infections from pooled faecal samples from sheep flocks across Greece and (b) to evaluate flock-related factors potentially associated with the presence of these infections in the flocks. An extensive countrywide study was performed on 325 sheep farms throughout Greece; faecal samples were collected from ewes and processed for the identification of helminth parasites. Helminths were detected in samples from 92.9% of flocks; these included Dicrocoelium dendriticum (16.7% of flocks), Fasciola hepatica (0.6%), Paramphistomum cervi (2.2%), Moniezia spp. (18.8%), Trichostrongylidae (85.5%), Nematodirus spp. (18.8%), Strongyloides papillosus (7.1%), Trichuris spp. (20.0%) and lungworms (17.8%). Mean Trichostrongylidae counts across all flocks in the study were 215 epg. Specifically, for Trichostrongylidae, there were differences between flocks that had or had not received anthelmintics during the two months prior to sampling, as well as between flocks located in various areas of the country. In multivariable analyses, for the outcome ‘high (>300) epg counts in faecal samples’, the month into the lactation period at sampling and the application of reproductive control practices on the farm emerged as significant factors; for the outcome ‘high proportion (>63%) of Teladorsagia spp. in faecal samples’, the availability of straw bedding emerged as a significant factor; and for the outcome ‘high proportion (>63%) of Haemonchus contortus in faecal samples’, the age of the farmer emerged as a significant factor. For the outcome ‘presence of Trichuris spp. in faecal samples’, the provision of finished feed (concentrate) to animals emerged as a significant factor, whilst, finally, for the outcomes ‘presence of D. dendriticum in faecal samples’ and ‘presence of lungworms in faecal samples,’ no significant factors emerged.
