Use of cecal microflora cultured under aerobic or anaerobic conditions in the control of experimental infection of chicks with Salmonella Enteritidis.
One-day-old broiler chicks received cecal microflora (CM) cultured under aerobic, anaerobic conditions, or both (mixed) and were then infected with Salmonella Enteritidis, in order to compare the efficacy of these different types of culture in terms of the number of chicks infected, cecal colonization and faecal excretion of the challenging bacteria. Regardless of culture type, CM always led to a smaller number of S. Enteritidis for any of the parameters studied compared to untreated chicks. Aerobic CM demonstrated better efficacy in reducing the number of infected chicks and cecal colonization by S. Enteritidis, followed by mixed CM. No difference was observed in faecal excretion of S. Enteritidis between the chicks that received different types of CM culture.
