“…Some studies have indicated that E. coli dies off faster than Salmonella spp. (10,19,34,36) and therefore is not a suitable indicator for the presence of this pathogen.…”

“…The optimum dispersing and flocculation conditions have to be determined for each soil type and the recovery percentage can be dependent on the inoculum level. Traditional culture methods for monitoring survival of salmonellas in soil are selective plating on agar and the most probable number technique (Gudding and Krogstad 1975;Chandler and Craven 1980;Watson 1980), both of which require growth of the cells in/on the media used. New methods were therefore required for the direct counting of salmonellas in soil.…”

“…Dans les sols, des facteurs favorisant la survie des coliformes et des streptocoques fécaux ont été mis en évidence par différents auteurs (KIBBEY et al, 1978 ;LABELLE et al, 1980 ;POSTGATE, 1967), en particulier le taux d'hydratation et un pH proche de la neutralité (BELL, 1976, GUDDING et al, 1975. Pour évaluer la survie le nombre des facteurs à prendre en compte est très important, humidité atmosphérique, temps pluvieux, température, insolation, caractéristiques physiques du sol, état de la microflore (RUDOLFS et al, 1951).…”
