Screening of poultry samples for salmonella typhimurium by PCR assay

Abstract

Poultry samples viz., cloacal swabs, egg swabs, poultry faeces and feed were screened for Salmonella Typhimurium. A set of primers derived from fli C gene were employed to standardize PCR for detection of Salmonella Typhimurium from poultry samples, which gave specific amplification of a 620 bp fragment. Boiling and snap chilling method used for template preparation. Screening of 112 samples revealed that 12 samples positive for Salmonella Typhimurium by PCR assay.
