Abstract excerpt
OBJECTIVE: In order to reveal why SEF14 fimbriae are restrictively expressed on strains of serogroup D salmonella, mainly S. enteritidis and S. dublin, the difference and variation of the sef14 operon gene clusters in S. enteritidis and related serogroup-D Salmonella were analyzed. METHODS: The genes encoding subunits of sefA, sefD and sefR in S. pullorum, S. enteritidis and S. dublin were amplified by PCR method...
