  • Title: [Structural organization and mechanisms of mobility of the gene cassette coding for resistance to antibiotics and bacterial virulence factors].
    Author: Il'ina TS.
    Journal: Mol Gen Mikrobiol Virusol; 2001; (1):3-12. PubMed ID: 11236739.
    Abstract:
    The review is focussed on two types of gene cassettes which are significant in bacterial variability. The first type are cassettes with antibiotic resistance genes; these are the smallest mobile genetic elements including a gene (most commonly an antibiotic resistance gene) and a short sequence acting as a recombination site. Sometimes these cassettes contain genes not responsible for antibiotic resistance but their functions are not yet known. The second type contains large clusters of genes coding for bacterial virulence factors. They were termed "pathogenicity islands" due to their difference in the percentage of G-C pairs in comparison with bacterial chromosomes, in which they are contained. The structural organization and mechanisms of mobility of various types of gene cassettes are discussed.
