| Résumé: | Various fluorescent conjugated lectins have been used for the detection of glycoconjugates on nematode surfaces under light microscopy. Several problems have been experienced with these reagents including penetration of the cuticle by fluorescent lectins, non-glycoconjugate specificity, strong nematode autofluorescence at the emission wavelength of the fluorescent dye, and prevention of persistent visualization due to rapid quenching of the fluorescent components. Gold-conjugated reagents combined with silver enhancement alleviated these difficulties when working with three phytonematode species (Heterodera avenae, H. latipons, and Meloidogyne javanica) and two entomopathogenic species (Steinernema carpocapsae and S. glaseri) under light-microscopy visualization of binding by fluorescent lectins and neoglycoproteins. Moreover, gold-conjugated reagents resulted in stable bindings that enabled long-term observations |
