In the day-old chick, physiological stress in the form of high or low temperatures or feed and water deprivation either interfered with colonization or altered the protection provided by normal intestinal microflora against subsequent challenge with

Both the native intestinal microflora of chickens that protected chicks against salmonellae and Escherichia coli and native turkey intestinal microflora were evaluated for their reciprocal protective capacity in both species against Salmonella typhim

Twelve compounds were evaluated as salmonella antagonists in commercial meat and bone meal. The test organism was a nalidixic acid-resistant strain of Salmonella infantis. Adequate moisture to support salmonella growth was assured by the addition of

A native gut microflora of chickens that protected chicks against Salmonella was evaluated against six pathogenic strains of Escherichia coli using similar methodology. Nalidixic-acid-resistant forms of the E. coli strains were derived for use in see

An improved individual challenge test system is described for evaluation of competititve exclusion of salmonellae in day-old chicks by native gut microflora. Evaluation of salmonella protection is based on culture of cloacal and fecal samples by enri

Direct culture and fluorescent antibody (FA) procedures were used for examining approximately 6200 samples of poultry floor or nest litter for salmonellae. Each sample was cultured directly in tetrathionate brilliant-green (TBG) broth, incubated at 4

Chicks infected with Salmonella typhimurium at 1 day of age were treated with normal intestinal flora starting 3 or 9 days later. Chicks were reared on the floor in isolated pens with wood shavings for litter. Cloacal-swab cultures were the main crit

A native intestinal microflora of chickens which is protective against salmonella readily transferred to penmates and apparently to birds in adjacent pens. The microflora not only minimized infection resulting from exposure following colonization of

Resistance of young chicks and poults to salmonella exposure was substantially increased by early oral administration of intestinal contents or feces from selected adult chickens. Protection was secured also by administering anaerobic broth cultures
