Abstract:
This study evaluated bacterial recovery from rectal swabs stored at -20 °C for one month in Cary Blair medium. Enrichment methods markedly improved detection of Escherichia coli and Salmonella enterica compared to direct plating. Tryptone Soy Broth best recovered E. coli, while Peptone Water enhanced S. enterica recovery, strengthening surveillance reliability in low-resource settings.
