Four independent molecular methods were used to characterize the Salmonella enterica subsp. enterica serovar choleraesuis live vaccine strains SC-54 and Suisaloral and to differentiate them from S. choleraesuis field isolates. Plasmid analysis revealed the presence of seven plasmid profiles. A virulence plasmid of 52-kbp was identified by hybridization with(More)
A highly discriminatory molecular typing system for isolates of Salmonella enterica subsp. enterica (S.) serovar Hadar was developed based on the data obtained from 34 epidemiologically unrelated S. Hadar isolates from Germany and Brazil. Plasmid profile analysis and macrorestriction analysis with the enzymes XbaI, SpeI and BlnI represented the most(More)
Seventy-six Salmonella enterica subsp. enterica serovar Enteritidis (S. Enteritidis) isolates which represented 14 phage types and RDNC isolates were investigated by several independent molecular methods. Eleven different plasmid profiles were detected. Plasmid-encoded virulence genes of the spv gene cluster were shown by hybridization with a spvB/C gene(More)
A total of 25 epidemiologically unrelated Salmonella enterica subsp. enterica (S.) serovar Typhimurium DT009 isolates from various human and animal sources, the original S. Typhimurium DT009 Zoosaloral live vaccine strain and two Zoosaloral strains reisolated from vaccinated chickens were investigated by various molecular typing methods (I) to determine the(More)
