title: Cyathostominae (Nematoda) parasites of Equus caballus in some Brazilian states.
abstract: Thirty six horses from nine Brazilian states (Goiás, Minas Gerais, Pará, Maranhão, Piauí, Paraíba, Pernambuco, Rio Grande do Norte, and Ceará) were examined for infections by small strongyles. The following species were identified: Cylicocyclus nassatus, C. insigne, C. brevicapsulatus, C. leptostomum, C. radiatus, C. ultrajectinus, C. ashworthi, Cylicostephanus goldi, C. calicatus, C. minutus, C. longibursatus, Petrovinema poculatum, Coronocyclus coronatus, C. labiatus, C. labratus, Cyathostomum catinatum, C. pateratum, C. alveatum, Parapoteriostomum euproctus, Cylicodontophorus bicoronatus, Poteriostomum ratzii, P. imparidentatum and Gyalocephalus capitatus. The most prevalent were C. longibursatus (100%), C. nassatus (97.22%) and C. catinatum (94.44%). They were also the most abundant species, comprising 31.84, 23.71 and 14.14%, respectively, of the Cyathostominae parasites found. Infections were found to include 2-17 species in a single horse, with variable associations.
