摘要：

As part of a USDA/APHIS study on the prevalence of Salmonella enteritidis in spent laying hens, 3700 pooled cecal samples were cultured for Salmonella. Samples were received from a single processing plant and represented 81 commercial egg-type layer flocks from nine southern states. Salmonella were isolated from 2418 of the 3700 (65.4%) cecal pools, but only six isolates were serotype enteritidis. S. enterididis was isolated from three flocks from two states but was detected in only six of 140 samples from those flocks. Various Salmonella isolation media and procedures were compared. Xylose-lysine-tergitol-4 plates detected 64% of the total Salmonella-positive cecal samples. Brilliant green agar with novobiocin detected 72% of the total Salmonella-positive samples. When used in combination, 82% of the positive samples were detected with these two plates. The remaining 425 Salmonella-positive samples were detected after delayed secondary enrichment.
