BACKGROUND AND OBJECTIVES Entomopathogenic nematodes, belonging to the family heterorhabditis and steinernematidae, are reported to be symbiotically associated with specific bacteria and the secondary metabolites produced by these bacteria possess antimicrobial activity. In this study, bacteria were isolated from nematodes belonging to the family rhabditidae, and the antimicrobial activity was ...

Este trabajo fue realizado entre el 2006-2010 en campos de trigo la región pampeana, Argentina. El objetivo determinar especies nemátodos parásitos patógenos gusanos blancos, plaga importante del suelo. Las muestras fueron tomadas con pala sitios seleccionados al azar. Larvas Diloboderus abderus y Cyclocephalla signaticollis (Scarabaeidae) recolectadas suelo a mano pala. Trece pertenecientes 5 ...

The invariant development of free-living nematodes combined with the extensive knowledge of Caenorhabditis elegans developmental biology provides an experimental system for an analysis of the evolution of developmental mechanisms. We have collected a number of new nematode species from soil samples. Most are easily cultured and their development can be analyzed at the level of individual cells ...

Summary The sex organs are important for nematode systematics, but the associated muscles rarely used as phylogenetic characters. This research aimed to study musculature of Panagrolaimus detritophagus , using confocal microscopy. ring-shaped anal sphincter is pierced by a biconical X-structure and connected two pairs processes subventral stomato-intestinal dorsal body wall. female has vaginal ...
