We report evidence of interspecies gene transfer between the important virulence factor genes sfbI and gfbA. Because the identified group G streptococcus gfbA types possess DNA cassettes that can be identified in a number of group A streptococcus strains, it appears that homologous recombination is occurring between these species.
我们报告了重要毒力因子基因sfbI和gfbA之间种间基因转移的证据。由于已鉴定出的G群链球菌gfbA类型拥有可在多种A群链球菌菌株中识别的DNA盒式结构,看来这些物种之间正在发生同源重组。
