答:GBS,又名无乳链球菌(S.agalactiae)。由于该菌引起的感染不只限于牛乳房炎,其细胞壁中含有多糖物质又属于抗原构造分类中的B族(或B组),也称为B族链球菌(或B组链球菌)。该菌为革兰阳性链球菌,大多数菌落在血平皿形成透明的溶血环,但有11%的GBS不溶血。GBS可正常寄居于阴道和直肠,它是一种条件致病菌,是引起新生儿感染性疾病的重要病因,具有高发病率和高死亡率的特征。
A: GBS, also known as S. agalactiae. As the infection caused by this bacterium is not limited to bovine mastitis, polysaccharide substances in its cell wall belong to group B (or group B), also known as group B streptococci (or group B streptococci) in the antigen structural classification. The bacteria is Gram-positive Streptococcus, the majority of colonies in the blood plate formation of transparent hemolytic ring, but 11% of GBS hemolysis. GBS can normally reside in the vagina and rectum, which is a kind of opportunistic pathogens, is an important cause of neonatal infectious diseases, with high morbidity and high mortality characteristics.
