Fluoroquinolone resistance in Streptococcus pneumoniae isolated from Hong Kong as part of Prospective Resistant Organism Tracking and Epidemiology for the Ketolide Telithromycin 1999/2000 was found to be due to the spread of the Spain(23F)-1 clone (mainly a Spain(23F)-1-14 variant). All the isolates were multidrug resistant but were susceptible to quinupristin-dalfopristin, linezolid, and telithromycin. The Spain(23F)-1 clone also occurred among antimicrobial-susceptible isolates, which suggests that the primary source of this clone may have been Asia rather than Iberia.
作为1999/2000年酮内酯类泰利霉素前瞻性耐药菌追踪与流行病学研究的一部分,从香港分离出的肺炎链球菌对氟喹诺酮耐药,发现这是由于西班牙(23F)-1克隆株(主要是西班牙(23F)-1-14变体)的传播所致。所有分离株均对多种药物耐药,但对奎奴普丁-达福普汀、利奈唑胺和泰利霉素敏感。西班牙(23F)-1克隆株也出现在药敏试验敏感的分离株中,这表明该克隆株的主要来源可能是亚洲而非伊比利亚半岛。
