Abstract

Penicillin-binding properties and characteristics of penicillin-binding proteins (PBPs) were investigated in several clinical isolates of Streptococcus pneumoniae differing in their susceptibilities to penicillin (minimal inhibitory concentration [MIC], 0.03 to 0.5 microgram/ml) and compared with the penicillin-susceptible strain R36A (MIC, 0.07 microgram/ml). Several changes accompanied the development of resistance: the relative affinity to penicillin of whole cells, isolated membranes, and two major PBPs after in vivo or in vitro labeling decreased (with increasing resistance). Furthermore, one additional PBP (2') appeared in four of five relatively resistant strains with an MIC of 0.25 microgram/ml and higher. PBP 3 maintained the same high affinity toward penicillin in all strains under all labeling conditions.

摘要

对几种对青霉素敏感性不同(最低抑菌浓度[MIC]为0.03至0.5微克/毫升)的肺炎链球菌临床分离株的青霉素结合特性及青霉素结合蛋白(PBPs)的特征进行了研究,并与青霉素敏感菌株R36A(MIC为0.07微克/毫升)进行了比较。耐药性的产生伴随着几个变化:体内或体外标记后,全细胞、分离膜和两种主要PBPs对青霉素的相对亲和力降低(耐药性增加)。此外,在五株MIC为0.25微克/毫升及更高的相对耐药菌株中,有四株出现了一种额外的PBP(2')。在所有标记条件下,所有菌株中的PBP 3对青霉素都保持相同的高亲和力。
