FIRST RECORD OF DIPLOSCAPTER CORONATA (NEMATODA: RHABDITIDAE), A FACULTATIVEPARASITE OF MAN, ASSOCIATED WITH TOMATO CROPS IN ARGENTINA. Salas, Augusto, J. M.Rusconi, D. Eliceche, and M. F. Achinelly. Centro de Estudios Parasitológicos y de Vectores,Facultad de Ciencias Naturales y Museo, (UNLP), CONICET. Argentina. Diploscapter coronata (Cobb, 1893) Cobb, 1913, is a free-living soil bacterial-feeding nematode, found in compost, sewage or agricultural soil and as facultative parasite of insects and vertebrates, even humans. The clinical symptoms include epigastric tenderness, diarrhea, crampy abdominal pain, weakness and nauseas. They have been considered as a potential carrier of bacteria pathogenic to the surface of preharvest fruits and vegetables in contact withsoil. In this note we reported the presence of D. coronata in the framework of different agroecological labors in Argentina. Soil samples associated with tomato crops (Lycopersiconesculentum) were taken and processed by the centrifugation method to isolated nematodes.Specimens were identified by morphological and morphometric characteristics of females.Diploscapter coronata was characterized by annulated cuticle, two pairs of lips in the mouthregion, lips transformed into a pair of medial, outwardly acting, distally bifurcate fossores and apair of lateral lamellae, rhabditoidal type of oral cavity, absence of glottoid apparatus. Thedetection of this nematode in greenhouses where dogs, cats and poultry live together withoutany health control, highlight the importance of applying proper hygiene measures duringagricultural practices to prevention of infections in vertebrates and humans. This reportconstitutes the first record of this nematode species and genus for Argentina.
