A number of 689 Streptococcus suis isolates collected nationwide from diseased and healthy pigs from 1987 to 1996 were surveyed for antibiotic susceptibilities to 11 drugs. No isolates resistant to amoxicillin, chloramphenicol, and sulfamethoxazole/trimethoprim were found. Isolates were highly susceptible to penicillins (penicillin G, ampicillin, and amoxicillin) except cloxacillin. They were not susceptible to tetracycline, streptomycin, and kanamaycin (MIC90 50 microg/ml, > or = 100 microg/ml, and > or = 100 microg/ml, respectively). Multiple-resistant isolates (> or = 3 antimicrobial agents) were found in 20.3% of all isolates tested.
对1987年至1996年期间从全国患病和健康猪中收集的689株猪链球菌分离株进行了11种药物的药敏试验。未发现对阿莫西林、氯霉素和磺胺甲恶唑/甲氧苄啶耐药的分离株。除氯唑西林外，分离株对青霉素类（青霉素G、氨苄西林和阿莫西林）高度敏感。它们对四环素、链霉素和卡那霉素不敏感（MIC90分别为50微克/毫升、≥100微克/毫升和≥100微克/毫升）。在所有测试分离株中，20.3%的分离株为多重耐药株（对≥3种抗菌药物耐药）。
