Modulation of spore adhesion of the hyperparasitic bacterium Pasteuria penetrans to nematode cuticle [PDF]
Monoclonal antibodies (mAb) raised to the cuticule surface of second-stage juveniles (J2) of the nematode Heterodera cajani were partially characterized by immunofluorescence and Western blot analysis. Five antigens with relative molecular weights (M(r)) 55, 80, 110, 180 and 210 kDa were identified with six mAb.

Minimal Growth Temperature of Pasteuria penetrans.
Pasteuria penetrans is an obligate, mycelial, and endospore-forming bacterial parasite of Meloidogyne spp. with promise for the management of root-knot nematodes. Our objective was to use regression analysis of developmental time (days) to various temperatures to determine the minimal temperature for growth and development of P.

New developments in the estimation of spores of Pasteuria penetrans
New developments in the estimation of free spores of Pasteuria penetrans, a hyperparasite of plant-parasitic nematodes, including Meloidogyne spp., have been tested in contrasted textured soils. They were dedicated to improving the recovery of spores.

Population Development of Pasteuria penetrans on Meloidogyne arenaria.
A microplot study on the influence of cropping sequences with peanut in summer and bare fallowed or cover crops of rye or vetch in winter on the population development of Pasteuria penetrans was initiated in the spring of 1987. The number of spores of P.

Parasitism of Helicotylenchus lobus by Pasteuria penetrans in Naturally Infested Soil.
The population density of Helicotylenchus lobus and the percentage of the population with spores of Pasteuria penetrans were determined for 10 monthly intervals in naturally infested turf grass soil at Riverside, California. The percentage of nematodes with attached spores ranged from 40% to 67%.

Temperature-Dependent Development of Pasteuria penetrans in Meloidogyne arenaria.
Pasteuria penetrans is a promising biological control agent of plant-parasitic nematodes. This study was conducted to determine effects of temperature on the bacterium's development in Meloidogyne arenaria. Developmental stages of P. penetrans were viewed with a compound microscope and verified with scanning electron microscopy within each nematode at ...

Distribution and Downward Movement of Pasteuria penetrans in Field Soil.
Endospores of Pasteuria penetrans were evaluated for their vertical distribution in field soil and their downward movement through soil in the laboratory. In the field trial, the number of endospores attached to second-stage juveniles (J2) of Meloidogyne arenaria race 1 varied greatly in different soil depths.

Persistence and Suppressiveness of Pasteuria penetrans to Meloidogyne arenaria Race.
The long-term persistence and suppressiveness of Pasteuria penetrans against Meloidogyne arenaria race 1 were investigated in a formerly root-knot nematode suppressive site following 9 years of continuous cultivation of three treatments and 4 years of continuous peanut. The three treatments were two M.
