Abstract

The porA genes from serogroup A, subgroup III strains isolated in the People's Republic of China in 1966 and in 1984 and 1985 were amplified by PCR at an annealing temperature of 75 degrees C. The DNA sequences (5 strains) and the restriction patterns generated by MspI (14 strains) were identical, unlike the results reported by Peixuan et al. (Z. Peixuan, H. Xujing, and X. Li, J. Clin. Microbiol. 33:458-462, 1995). Furthermore, PCR products which were amplified at an annealing temperature of 60 degrees C, as described by Peixuan et al., were heterogeneous in our study.

摘要

对1966年以及1984年和1985年在中国分离出的A血清群、III亚群菌株的porA基因，在75℃退火温度下通过聚合酶链反应（PCR）进行扩增。DNA序列（5株）以及由MspI产生的限制性酶切图谱（14株）是相同的，这与Peixuan等人（Z. Peixuan、H. Xujing和X. Li，《临床微生物学杂志》33:458 - 462，1995年）报道的结果不同。此外，按照Peixuan等人所述在60℃退火温度下扩增的PCR产物，在我们的研究中是异质的。
