Background   Libyostrongylus douglassii ,  Libyostrongylus dentatus  and  Libyostrongylus magnus  are nematodes that infect ostriches. The first species has been identified in ostriches from Africa, Europe, Americas and Oceania. Although the natural range of ostriches is Africa,  L. dentatus  was first described in birds from the USA and later identified in Brazil, where co-infections with  L. douglassii  have been commonly reported.  Libyostrongylus magnus  is known from the original description only. There are a few reports on infections with  L. douglassii  in ostriches from Africa and all farmed birds examined are from the southern region of the continent. The aim of this report was to verify  Libyostrongylus  spp. infections in wild ostriches from Ethiopia. Fecal samples from ostriches,  Struthio molybdophanes , were collected and submitted to coproculture. Infective larvae were identified to the species level based on general morphology and morphometry. In addition, phylogenetic analysis of the first and second internal transcribed spacer (ITS1 and ITS2) of the nuclear ribosomal DNA was performed.    Results  Infective larvae from Ethiopian ostriches had the morphological characteristics of  L. dentatus . Confidence interval estimate for sheath tail length from Ethiopian  Libyostrongylus  sp. isolates overlapped one for Brazilian  L. dentatus . Neighbor-joining and Maximum Likelihood phylogenetic trees based on sequences of the ITS1 and ITS2 regions revealed that the Ethiopian samples belong to the  L. dentatus  species clade. Monospecific infections with  L. dentatus  were confirmed in Ethiopian wild ostriches, opposed to the co-infections typically found in the Americas.    Conclusions  To our knowledge, this is the first record of  L. dentatus  from African ostriches, the region from which this parasite originated.
