Application of rapid dot blot immunoassay for detection of Salmonella enterica serovar enteritidis in eggs, poultry, and other foods.

abstract：:Leghorn hens over 50 weeks of age were assigned to two treatment groups designated as either unmolted controls or molted. A forced molt was induced by a 9-day feed withdrawal, and each hen was challenged orally with 10(5) Salmonella enteritidis organisms on day 4 of feed withdrawal. On days 4 and 9 of molt, the number...
