hlyA. The O1 strains mentioned was isolated from clinical sample and negative for ctxA, tcpA, tcpI. TcpI gene was detected in 2 non-O1/non-O139 strains with the absence of tcpA. A combination of molecular fingerprinting method had distinguished the strains into 43 profiles with F value = 0.59 -0.95. The O1 strain mentioned was clustered in-between toxigenic O1/O139 and non-toxigenic, non-O1/non-O139 strains. As for the 2 non-O1/non-O139 strains, one of them was related with O1 toxigenic strains

The results also revealed the virulence potential of non-toxigenic, non-O1/non-O139 strains as the close relationship between the strains and O1/O139 toxigenic strains were developed and proved by the virulence profile.
