  abstract = {{I}n {S}enegal, a study was carried out in a field cultivated with {A}frican egg-plant ({S}olanum aethiopicum) in order (1) to determine soil size fractions infested both with {M}eloidogyne javanica and {P}asteuria, (2) to compare the efficacy of soil fraction dispersion methods in the recovery of both organisms and (3) to estimate the concomitant distribution of the two organisms in the different soil fraction sizes. {S}amples were taken from four areas: severely-infested ({M}+) with {M}. javanica with a high percentage ({I}+) of {P}asteuria-infected juveniles, severely-infested ({M}+) with a tow percentage of infected juveniles ({I}-), minimally-infested ({M}-) with a high percentage of infected juveniles ({I}+) and minimally-infested ({M}-) with a low percentage of infected juveniles ({I}-). {T}he samples were dispersed and fractionated using two different techniques in order to evaluate soil aggregation (size fractions > 200, 50-200, 20-50 and 0-20 mu m). {T}he numbers of free entities of {P}asteuria penetrans were estimated per size fractions. {T}he proportion of {P}asteuria-infected juveniles (biological detection of {P} penetrans) was estimated in order to correlate the infection rate to the distribution of free entities of {P} penetrans. {R}egardless of sampling area, the 50-200 mu m size fraction predominated, followed by largest particle (> 200 mu m) size. {T}he distribution of {P}asteuria spores in the soil was not linearly correlated to the distribution of {P}asteuria-infected juveniles. {T}he influence of the soil characteristics on the relationship between the two organisms is discussed.
