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 with soil. In this note we reported the presence of D. coronata in the framework of different agro-ecological labors in Argentina. Soil samples associated with tomato crops (Lycopersicon esculentum) 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 mouth region, lips transformed into a pair of medial, outwardly acting, distally bifurcate fossores and a pair of lateral lamellae, rhabditoidal type of oral cavity, absence of glottoid apparatus. The detection of this nematode in greenhouses where dogs, cats and poultry live together without any health control, highlight the importance of applying proper hygiene measures during agricultural practices to prevention of infections in vertebrates and humans. This report constitutes the first record of this nematode species and genus for Argentina.
