摘要: sistant forms of the E. coli strains were derived for use in seederbird and individual-bird challenge tests. A substantial degree exclusion intestinal colonization each six pathogenic was secured chicks that had been treated with native gut microflora. appeared to colonize chiefly crop cecum. Native microflora limited a much lesser "normal" present tract test chicks. The mechanism protection appears be similar Salmonella: competed sites attachment.
