Epidemic strains of Salmonella enterica subsp. enterica serovar Bovismorbificans isolated in southern Italy during the years 1989-1991 were submitted to a molecular epidemiological study in comparison with isolates identified in the years 1980-1988 in the same geographic area.
Genomic DNA fragments obtained by digestion with BglI or Eco RI hybridized with Escherichia coli rRNA to produce three distinct, but highly related patterns.
Ribotype 1, which had never been identified before 1989, was found to characterize most of the strains identified between 1989 and 1991.
Such a finding supports the hypothesis of emergence and spread of a new bacterial clone associated with the increased number of human infections reported in the same years in southern Italy.
