Abstract: | An increase in the number of multidrug-resistant Salmonella enterica serovar Typhimurium strains (definitive phage type DT20a and DT120) as well as the occurrence of DT104 strains during 2003-2005 in Slovakia was documented. Based on the results of the molecular analysis we suggest that multidrug-resistant DT20a and DT120 phage types are more closely related to multidrug-resistant phage type, and that the occurrence is probably due to changes in the phage susceptibility of DT104. Continued surveillance and molecular analysis should be maintained to follow the spread of these new multidrug-resistant DT104 variants in animals and humans. |
