Persistence of Salmonella typhimurium in porcine gut microflora

摘要

Chlortetracycline administration, at 55 mg/l, to a continuous flow culture of mixed porcine gut bacteria enhanced the rate of clearance of a chlortetracycline resistant Salmonella Typhimurium from the culture, although the Salmonella was eventually excluded from the culture by 8 days post challenge. As expected, chlortetracycline administration, at 110mg/l, to a continuous flow culture of mixed porcine gut bacteria had little effect on the persistence of a chlortetracycline resistant strain of Salmonella typhimurium.
