The influence of litter on Salmonella typhimurium infection in poultry.
Observations were made on the persistence of S. typhimurium in litter and houses from an outbreak of disease in broilers. Subsequent studies were made of the persistence of the organism in the litter and of its infectivity to day-old chicks. No S. typhimurium was isolated from the houses after cleaning, disinfection and fumigation. No infection occurred in the chicks reared on the contaminated litter and the organism was rapidly eliminated from the litter. The results are described and compared with previous investigations.
