Abstract
Many Streptococcus suis isolates from porcine endocarditis in slaughterhouses have lost their capsule and are considered avirulent. However, we retrieved capsule- and virulence-recovered S. suis after in vivo passages of a nonencapsulated strain in mice, suggesting that nonencapsulated S. suis are still potentially hazardous for persons in the swine industry.
摘要
从屠宰场猪心内膜炎中分离出的许多猪链球菌菌株已失去其荚膜，被认为无毒力。然而，我们在将一株无荚膜菌株在小鼠体内传代后，获得了恢复荚膜和毒力的猪链球菌，这表明无荚膜猪链球菌对养猪业人员仍有潜在危害。
