Protein Profiles in Different Strains of Aeromonas hydrophila Isolated from Retail Foods
MetadataShow full item record
In this study, whole cell protein profiles of 20 local strains of Aeromonas hydrophila isolated from different foods in Turkey and one reference strain (ATCC 7966) were analyzed by SDS-PAGE (sodium dodecylsulfate polyacrylamide gel electrophoresis). It was observed that there was variability among the strains. Molecular weight of proteins were found to be between 21-116 kDa. The protein polypeptide bands from 37.8 to 101.4 kDa were common in both local strains and reference strain of A. hydrophila. The results of this study indicated that there is a genetic similarity between strains of A. hydrophila and reference strain (ATCC 7966). These protein patterns are likely to be beneficial to differentiate between the strains in epidemiological studies.
