Heterogeneity of the amino-acid sequences of Escherichia coli Shiga-like toxin type-I operons.

Gene - 3 Feb 1995

Paton A W, Beutin L, Paton J C

Abstract excerpt

PCR was used to amplify approx. 1470-bp segments of DNA containing complete Shiga-like toxin type I (sltI) operons from Escherichia coli strains belonging to serotypes O48:H21, O111:H- and OX3:H8. These fragments were cloned and DNA sequence analysis identified several variations, as compared with published sltI sequences. All three sltI genes analysed were more closely related to Shiga toxin-encoding genes (sht)...
