Abstract: <smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="place" downloadurl="http://www.5iantlavalamp.com/"> Virulence in <i style="">Salmonella</i> is reported to be caused by large plasmids of 60-100 kb. In the present study, 24 isolates of four <i style="">Salmonella</i> serovars (<i style="">S</i>. Dublin, <i style="">S</i>. Abortusequi, <i style="">S</i>. Bareilly and <i style="">S</i>. Choleraesuis) were studied for their <i style="">in vivo</i> virulence, plasmid profiling and virulence (<i style="">Vir</i>) gene detection by PCR. Nineteen isolates were found to be virulent inducing different degrees of mortality in mice. In 5 non-virulent isolates, the large plasmid was absent and there was also no amplification of <i style="">Vir</i> gene by PCR. It clearly indicates a positive correlation between virulence of the organism and the presence of plasmid and amplification of <i style="">Vir</i> gene. </smarttagtype>
