Morphological and biometrical studies were carried out to improve the differential diagnostic of infective larvae of Strongylus vulgaris, Strongylus equinus, Strongylus edentatus, Triodontophorus spp., Triodontophorus tenuicollis, Poteriostomum spp., Gyalocephalus capitatus, Cylicocyclus radiatus, Cylicocyclus nassatus, Cylicocyclus ashworthi, Cylicostephanus minutus e Cylicostephanus poculatus. Pure cultures of larvae were obtained from eggs collected from adult female worms during necropsy of six naturally infected horses. Mixed cultures were obtained from feces of naturally infected horses from three counties of the State of Rio de Janeiro. The following measurements as total length, sheath tail length, esophageal and intestinal length, distance of genital primordium to the tip of the tail and width were considered as the main measurements in the identification of the third stage larvae. xix. A pictorial key for identifing infective larvae well as photomicrographies of the morphological characteristics were given in this work.

Estudos morfol?gicos e biom?tricos foram realizados para aprimorar o diagn?stico diferencial das larvas infectantes de Strongylus vulgaris, Strongylus edentatus, Strongylus equinus, Triodontophorus spp., Triodontophorus tenuicollis, Gyalocephalus Capitatus, Poteriostomum spp., Cylicocyclus radiatus, Cylicocyclus nassatus, Cylicocyclus ashworthi, Cylicostephanus minutus e Cylicostephanus poculatus. Culturas puras foram realizadas a partir de ovos retirados do ?tero de f?meas de helmintos obtidos do intestino grosso de equinos por ocasi?o de seis necropsias. Culturas mistas foram efetuadas com fezes de equinos coletadas em tr?s munic?- pios do Estado do Rio de Janeiro. As seguintes caracter?sticas das larvas de terceiro est?dio foram medidas: comprimento total, comprimento da cauda da bainha, comprimento do es?fago, comprimento do intestino, dist?ncia do prim?rdio genital ? ponta da cauda da bainha e largura. xvii. Os dados obtidos foram comparados aos de outros autores. Chave para identifica??o das larvas infectantes ? apresentada. Fotomicrografias das principais caracter?sticas morfol?- gicas e an?lise estat?stica gr?fica s?o fornecidas.
