[A METHOD FOR DIFFERENTIATION OF BACILLUS ANTHRACIS STRAINS AND PHYLOGENETICALLY RELATED SPECIES BASED ON
Abstract:
Nucleotide sequence analysis of several genes responsible for the anthrax pathogen definitive properties--motility and penicillinase activity--determined a chromosomal locus promising for interspecies differentiation. We demonstrated that the gene fliC encoding flagellin synthesis contains extended region, distinguishing B. anthracis strains from the majority of non-pathogenic and opportunistic bacilli. A novel method for the anthrax pathogen indication and identification based on determination of the differences in the chromosomal genes fliC and hom2 structure was suggested. A total of 60 strains of different Bacillus spp. (B. anthracis, B. cereus, B. thuringiensis, B. mycoides, B. megaterium, B. subtilis, etc.) were tested using two chromosomal DNA targets. The algorithm developed in this work permits to detect the pathogenic microorganism and reliably differentiate it from other Bacillus spp. representatives. The introduction of primers complementary to specific sequences of pXO1 and pXQ2 plasmids into the multiplex PCR makes it possible to receive additional information on proposed virulence of the isolate.
