A total of 19 Salmonella strains isolated from diverse sources were subjected to DNA fingerprinting by repetitive sequence PCR using ERIC and (GTG)5 primers for the discrimination of Salmonella enterica isolates at the serotype level. Fingerprints were binary scored and dendrogram was constructed for ERIC and (GTG)5 fingerprint bands. ERIC PCR produced unique patterns consisting of 4 to 16 bands ranging between 0.15 kb to 1.5 kb. Two distinct polymorphic bands at 210 bp and 300 bp were found in all the serotypes. (GTG)5 PCR fingerprint consist of 3 to 15 bands ranging from 0.29 kb to 1.25 kb. All the serotypes tested revealed single polymorphic bands at 900 bp. ERIC and (GTG)5 dendrogram presented fingerprint for all the 19 isolates and serotypes were grouped into three major branches A, B and C which was further subdivided into small groups. The results obtained in the present study indicated ERIC-PCR and (GTG)5-PCR fingerprinting were not so efficient in discriminating Salmonella isolates.
