Identification of Oxyspirura mansoni (Spirurida: Thelaziidae) in a free-range hen (Gallus gallus domesticus) and its intermediate host, Surinam cockroach (Pycnoscelus surinamensis) in Monterrey, Nuevo Leon, Mexico. Acta Zool. Mex [online]. 2014, vol.30, n.1, pp.106-113. ISSN 2448-8445.

The current report addresses the finding of ocular filariosis in a domestic adult hen, raised in a backyard, in a community near La Silla River, south Nuevo Leon, in Mexico. The hen was submitted to a veterinary practice due to weakness and diarrhea. During necropsy, three nematodes were found underneath the nictitating membranes in both of the bird's eyes. The nematodes were identified as Oxyspirura mansoni. The diagnostic was confirmed when the intermediate host of O. mansoni, the Surinam cockroach (Pycnoscelus surinamensis), was found in the hen's living environment.

Keywords : Oxyspirura mansoni; bird eyeworm; Pycnoscelus surinamensis; Surinam cockroach; free roaming hen; Gallus gallus domasticus.
