Of 83 strains of Neisseria gonorrhoeae isolated in Riyadh, Saudi Arabia, between April 1979 and August 1980, 10 produced beta-lactamase and had minimum inhibitory concentrations (MICs) of penicillin between 1 and greater than or equal to 4 micrograms/ml. Of the 73 (88%) non-penicillinase-producing strains, 55% had diminished sensitivity to penicillin (MIC = 0.06 micrograms/ml) and 11 (15%) were highly resistant (MICs ranging from 0.5-2 micrograms/ml). This high incidence of resistance may be due to widespread abuse of antibiotics; it also confirms that two mechanisms of resistance to penicillin exist in this species.
1979年4月至1980年8月间,在沙特阿拉伯利雅得分离出的83株淋病奈瑟菌中,10株产生β-内酰胺酶,青霉素最低抑菌浓度(MIC)在1至大于或等于4微克/毫升之间。在73株(88%)不产生青霉素酶的菌株中,55%对青霉素敏感性降低(MIC = 0.06微克/毫升),11株(15%)高度耐药(MIC范围为0.5 - 2微克/毫升)。这种高耐药发生率可能是由于抗生素的广泛滥用;这也证实了该菌种存在两种对青霉素的耐药机制。
