PFGE — pulsed-field gel electrophoresis; T — tonsil; NT — nontypable; E — environment; S — septicemia.

a

Strains 331 and 332, as well as the tonsil and environment isolates, were collected in the current study; the others strains were collected from earlier outbreaks.

b

Obtained from the combined results with PFGE and ISR-RFLP (an approach based on PCR amplification of a fragment of rRNA genes, including a part of the 16S and 23S genes and the 16S–23S rDNA intergenic spacer region [ISR], followed by restriction fragment length polymorphism).

c

These strains were isolated from blood samples of 2 pigs that died suddenly on the day of the visit to farm 5.
