First report of Libyostrongylus douglassii (Strongylida: Trichostrongylidae) in ostriches (Struthio camelus) from Mexico.

Nematodes of the Libyostrongylus genus are hematophagous parasites found under the ostrich's proventriculus membrane: they are frequent and can cause 50% of mortality in chicks and occasionally death in adults. With the aim of determining the presence of the Libyostrongylus genus in two private collections, one located in Ayapango, State of Mexico and the other in Amacuzac, Morelos, a total of 27 fecal samples were collected between August and December of 2016. Samples were analyzed using the flotation technique.
