Rectal administration of Escherichia coli O157:H7: novel model for colonization of ruminants.

abstract：:Nutritional and physical factors which influence the germination of akinetes of Nodularia spumigena (Cyanobacteriaceae) were examined. Low concentrations of phosphorus (<0.9 muM) were required for germination. Nitrate had no effect, but ammonia, at concentrations of >45 muM, inhibited germination. Salinities of >20 pe...
