摘要: We investigated the clonal relationships among 41 enterotoxigenic (ETEC) or non-enterotoxigenic (NETEC) Escherichia coli strains producing F17 a fimbriae isolated from diarrheic calves in France Belgium early 1980s. Twenty-three of 26 ETEC were highly clonally related, most them with O101:K32:H9-serotype. The NETEC also divided subgroups, O101:H-serotype. positive are no longer these countries. It is postulated that use vaccine including O101, K32 and H9 antigens addition to K99 (F5) explains strongly reduced isolation O101:K32:H9, E. clone.
