Pathological findings in the caeca of naturally infected ostriches, Struthio camelus Linnaeus, 1758 (Aves, Struthionidae) parasitized by Codiostomum struthionis (Horst, 1885) Railliet and Henry, 1911 (Nematoda, Strongylidae).
In order to characterize lesions associated with Codiostomum struthionis in ostriches, 10 caeca were examined on both macro- and microscopic levels. Parasites were found in the distal third of the caecum and characterized as C. struthionis. Thickened mucosa was identified macroscopically where parasites were observed in high concentrations. Nodular areas were also observed in the distal third of the infected caeca, as well as hemorrhagic areas abutting small ulcers surrounded by edema. These findings were not observed in healthy controls. The concentration of C. struthionis found in infected animals was directly correlated with the severity of lesions observed in each caecum. These results allowed us to infer that C. struthionis is responsible for lesions in ostrich caeca.
