从我国11个鸡场分离的64株奇异变形杆菌中，有6株含有沙门氏菌基因组岛1（SGI 1）。PCR图谱显示SGI 1 s基因的全序列为33.2 ~ 42.5kb。三个新的变体，SGI 1-W，SGI 1-X，和SGI 1-Y，已被表征。首次在SGI 1中鉴定出了lnuF、dfrA 25和qnrB 2等抗病基因。
Six out of the 64 studied Proteus mirabilis isolates from 11 poultry farms in China contained Salmonella genomic island 1 (SGI1). PCR mapping showed that the complete nucleotide sequences of SGI1s ranged from 33.2 to 42.5 kb. Three novel variants, SGI1-W, SGI1-X, and SGI1-Y, have been characterized. Resistance genes lnuF, dfrA25, and qnrB2 were identified in SGI1 for the first time.
