Subcutaneous infection of Lagochilascaris minor in domestic cats from Uruguay.

The nematode Lagochilascaris minor was collected from subcutaneous abscesses on the face and neck of three female cats aged 8 months, and 1 and 2 years. These cats were born in the Department of Maldonado, Uruguay. Female and male nematodes were 10.1-14.4 and 10.0-14.3mm long, respectively. The lips were one dorsal lip and two subventral lips separated from the body by a deep post-labial groove, and were separated from each other by triangular interlabial projections. The width of the lips was almost equal to the width of the post-labial collar. The vulva was near the middle of the female body. The eggs were oval or spherical and measured 0.059-0.073 mm long and 0.045-0.065 mm wide. Irregular-shaped pits were on the egg surface; 20-32 pits were around the equator of the eggs. The male posterior region was ventrally curved. Each spicule was about three quarters of the ejaculator duct length. From these findings, the nematodes were identified as L. minor. We believe this is the first report of its infection in Uruguay.
