Predatory behaviour of trapping fungi against srf mutants of Caenorhabditis elegans and different plant and animal parasitic nematodes
(1999-07)
The initial infection process of nematode-trapping fungi is based on an interaction between the trapping structure of the fungus and the surface of the nematode cuticle. A bioassay was designed to investigate the predatory ...
Meloidogyne incognita surface antigen epitopes in infected Arabidopsis roots
(1999-06)
Surface-coat epitopes of Meloidogyne incognita were detected in root tissues of Arabidopsis thaliana during migration and feeding site formation. A whole-mount root technique was used for immunolocalization of surface coat ...
Attachment tests of Pasteuria penetrans to the cuticle of plant and animal parasitic nematodes, free living nematodes and srf mutants of Caenorhabditis elegans
(1999-03)
Populations of Pasteuria penetrans isolated from root-knot nematodes (Meloidogyne spp.) and cyst nematodes (Heterodeua spp.) were tested for their ability to adhere to a limited selection of sheathed and exsheathed animal ...
Modulation of spore adhesion of the hyperparasitic bacterium Pasteuria penetrans to nematode cuticle
(1997-12)
Monoclonal antibodies (mAb) raised to the cuticule surface of second-stage juveniles (J2) of the nematode Heterodera cajani were partially characterized br immunofluorescence and Western blot analysis. Five antigens with ...
Diversity and partial characterization of putative virulence determinants in Pasteuria penetrans, the hyperparasitic bacterium of root-knot nematodes (Meloidogyne spp.)
(1997-08)
Antigens recognized by monoclonal antibodies (Mabs) raised to the surface of the obligate nematode hyperparasite Pasteuria penetrans were characterized. Using the attachment of spores of the bacterium to host nematodes to ...
Compatibility between Pasteuria penetrans isolates and Meloidogyne populations from Spain
(1997-06)
Several populations of Pasteuria isolated from fields in Spain were compared with other Pasteuria populations, held in collections at the Institute de Recerca i Tecnologia, Agroalimentaries (IRTA), Cabrils or IACR-Rothamsted, ...
Effects of long term storage and above normal temperatures on spore adhesion of Pasteuria penetrans and infection of the root-knot nematode Meloidogyne javanica
(1997-03)
The effects of storage and temperature on the attachment and infection of root-knot nematodes by the parasite Pasteuria penetrans were investigated. Storage for 11 years did not reduce the ability of P. penetrans to attach ...
Identification of the root-knot nematode, Meloidogyne incognita, using monoclonal antibodies raised to non-specific esterases
(1996-08)
The esterase isozyme from Meloidogyne incognita with pI similar to 4.95 was purified using a Rotofor electrophoresis system. The purified enzyme was then used to raise monoclonal antibodies. Hybridoma cell lines producing ...
Comparison of two sympatric Pasteuria populations isolated from a tropical vertisol soil
(1996-07)
An isolate of Pasteuria (designated PPMJ) recovered from the root-knot nematode Meloidogyne javanica, was characterized using host preference, spore morphometrics, and serology, and compared with another sympatric Pasteuria ...
Serologically based diagnostic and quantification tests for nematodes
(1996-05)
Plant parasitic nematodes are important plant pests which are difficult to identify and quantify. Serologically based techniques offer new ways to identify and quantify these parasites. Several factors need to be considered ...
