A cross-sectional serological survey was carried out to screen the small ruminants of Thessaly, Greece, for infection with Haemonchus contortus, lungworms (i.e. Cystocaulus ocreatus, Muellerius capillaris, Protostrongylus rufescens and Neostrongylus linearis) as a group, and for Cysticercus tenuicolis, Linguatula serrata and Oestrus ovis. A second objective was to determine the risk factors related to herd characteristics, management practices, farmer status and bioclimatic variables associated with these parasitic infections. %26lt;br%26gt;A total of 361 sheep and 179 goat serum samples were examined. The seroprevalences were 33.9%, 41.5%, 14.1%, 4.6% and 1.4% for H. contortus, lungworms, L. serrata, C tenuicolis and O. ovis, respectively. The final logistic regression model showed that farm location and temperature were associated with H. contortus, lungworm and L. serrata infections. Anthelmintic treatment, class of anthelmintic and rotation of grazing were associated with H. contortus and lungworm infections, while grazing with other herds was associated with lungworm and L. serrata infections; rain was associated with H. contortus and L. serrata infections. Farm type and age of farmer were associated with H. contortus infections and elevation was associated with lungworm infection. The results may help to formulate appropriate control strategies in Greece and other areas with similar climatic conditions in order to channel limited resources to mitigate only those risk factors which are significant to protect the profitability of the livestock industry.
