Abstract
Cyathostomins,  or  'small  strongyles',  are  the  most  important  equine  helminths  because  of their  worldwide  distribution,  spread  of  anthelmintic‑resistant  populations,  and  pathogenic impact.  The  so‑called  'selective  treatment'  of  those  animals  exceeding  a  certain  faecal  egg  count  (FEC)  has  recently  been  proposed  to  implement  cyathostomin  control  programmes.  The present study evaluated the extent of egg shedding in 475 horses living in 12 farms from 3 regions of Italy. All examined farms and 224 horses (47.6%) were positive for cyathostomins. 138 horses (28.8%) scored positive for cyathostomin FECs with a range of eggs‑per‑gram of faeces (epg) values of 50‑2,150. Further 86 horses (18.1%) were positive only under qualitative microscopy (i.e. < 50 epg). Of the animals with a FEC > 50 epg, 81 (17%) and 57 (12%) showed values  of  50‑200  and  >  200  epg,  respectively.  The  findings  from  this  study  demonstrated  a reduced presence of high‑shedding horses compared to results obtained in previous years in  the  same  study  areas,  despite  overlapping  climate  features  in  the  previous  5  years.  A  continuing  monitoring  of  epidemiological  and  biological  features  of  horse  cyathostomin infection  is  crucial  for  planning  intervention  programmes  aimed  to  maintaining  animal health and preserving the efficacy of parasiticides.
