研究了沙门氏菌SPI-1和SPI-2致病性岛的系统发育分布，SPI-1在8个亚特异群中均存在，但在V群（S. bongori）中未检测到SPI-2杂交序列。我们的数据表明SPI-2是肠球菌从S. bongori分离后获得的。
We investigated the phylogenetic distribution of the SPI-1 and SPI-2 pathogenicity islands in Salmonella spp. SPI-1 was present in representatives of ail eight subspecific groups, but no SPI-2-hybridizing sequences were detected in group V (S. bongori). Our data suggest that SPI-2 was acquired by S. enterica after its split from S. bongori.
