The effect of air on the conductance response of salmonellas in three selective media was investigated. When assays were carried out aerobically, the time to observe a presumptive positive in all media was reduced and the conductance change was larger than in assays done under microaerophilic conditions. Low (10 2 /ml) numbers of pre‐enriched salmonellas were detected only under aerobic conditions.
