  • Title: Phenotypic and genotypic diversity of Bacillus cereus isolates recovered from honey.
    Author: López AC, Alippi AM.
    Journal: Int J Food Microbiol; 2007 Jun 30; 117(2):175-84. PubMed ID: 17466403.
    Abstract:
    Of 433 honey samples collected in Argentina, 114 (27%) yielded Bacillus cereus isolates (27%) and 60 (14%) yielded other species of Bacillus. The Argentinian B. cereus isolates were compared with isolates recovered from honey from other countries (n=16) and with strain ATCC 11718. The 133 B. cereus isolates and the ATCC strain were characterized using rep-PCR fingerprinting with primers BOX, REP and ERIC, restriction fragment length polymorphism analysis of a 16S rRNA gene fragment (16S rRNA PCR/RFLP), and morphological and biochemical tests. There was a high degree of diversity, both phenotypic and genotypic among the isolates of B. cereus. Our results demonstrate the usefulness of rep-PCR genomic fingerprinting for characterizing populations of B. cereus. According to our knowledge, this is the first report of phenotypic and genotypic characterization of B. cereus isolates from honey.
