| Abstract: | Monoclonal antibodies to secretory granules in the dorsal or subventral esophageal glands were generated by injecting BALB/c mice with immunogens from preparasitic second-stage juveniles (J2) of Meloidogyne incognita. Antibodies specific for secretory granules in the J2 subventral esophageal glands or the dorsal gland were identified by indirect immunofluorescence microscopy. Only antibodies that reacted with granules in the J2 dorsal gland reacted with the esophageal gland lobe ofM. incognita adult females. The antibodies also reacted with secretory granules in both types of esophageal glands in M. javanica and M. arenaria J2 but not with granules in esophageal glands of Heterodera glycines J2. |
