title: [The communities of cyathostomes (Cyathostominae) in year-old and two-year-old Pure Blood Arabian mares].
abstract: BACKGROUND
  The objective of this study was to evaluate the strongyles species in 34 Pure Blood Arabian Horses: one-year-old mares (n = 12) and two-year old mares (n = 22) from the horse stud in 2005, kept under housed-pastured system and dewormed systematically, twice a year using the ivermectin compounds.
  
  
  METHODS
  The practical method of in vivo determination of strongyles species in horses is collection of these nematodes from the feaces after treatment. Nematodes were collected 24 hours after deworming from 1000 g sample of feaces, then were classified to appropriate species and relative abundance of strongyles community was determined.
  
  
  RESULTS
  In the feaces of horses after treatment 10 species of cyathostomes was determined: Cyathostomum catinatum (CAT), C. pateratum (PAT), Cylicocyclus nassatus (NAS), C. ashworti (ASH), C. leptostomus (LEP), C. insigne (INS), Cylicostephanus longibursatus (LNG), C. goldi (GLD), C. calicatus (CAL) and Coronocyclus coronatus (COR). No large strongyles (Strongylinae) was found. The relative abundance was the highest for following cyathostomes species: NAS (22%), CAT (18.1%), INS (17.7%), PAT (13.8%), LNG (9.1%) and LEP (8.2%). The relative abundance of cyathostomes species was similar in both group of mares. On the other hand CAL (15.8%) was common for the one-year-old mares and INS (25%) for the two-year-old mares. In vivo diagnositic of the infection is important from the perspective of individual small strongyle infections dynamics in horses and because of possible different pathogenicity of individual species of these nematodes.
