Studies on the lactose character in Salmonella S:41:z10.
A number of plasmids carrying the Lac+ character have been reported. Lac+ character of salmonella S:41:z10:- studied for transfer of Lac+ character to standard Escherichia coli K12 Lac-F- Nalr and Escherichia coli K12 F- Lac- Rifr, failed to transfer in in vitro experiments. Similarly, identification and characterisation of plasmid DNA by agarose gel electrophoresis technique did not show specific plasmid DNA as compared to standard molecular weight plasmids. Plasmid DNA appeared to have been embedded with chromosomal DNA molecule.
