Abstract


This study aimed to investigate the presence of Strongylus vulgaris on different horse establishments in Romania. A total number of 380 horses were enrolled in the study, representing: three stud farms (n=156); four sport/recreational establishments (n=75); and working horses (n=149). Overall, 106 premises/yards from 17 localities in 9 counties from North-Eastern, Center and Southern Romania were visited. Fresh fecal sample were collected from individual horses and were analyzed by a modified McMaster method for fecal strongyle egg per gram counting. Further, larval cultures were performed for morphological identification of S. vulgaris third stage larvae. Overall, of the investigated horses from studs, sport/recreational units, and working horses, 84.60%, 44.0%, and 79.20%, respectively were positive for strongyle. On coprocultures, cyathostomin-larvae were the most prevalent in all horse-establishment types, while S. vulgaris larvae were found only in working horses (12.1%; n=18). Other strongylin species have been identified, namely S. equinus, S. edentatus, Oesophagodontus robustus, and Triodontophorus spp. all in working horses, and Craterostomum acuticaudatum, in both working horses and horses for sport units. However, further studies are planned by using more sensitive technique for monitoring of S. vulgaris in Romanian horse farms.
