High Staphylococcus hyicus colonization rates were found in vaginal samples of healthy breeding sows and in skin samples of their offspring. Twenty-two different phage types were identified among the 720 isolates of S. hyicus examined. Two to 13 different phage types were isolated per herd. Phage typing, as well as characterization of about 10% of the isolates by plasmid profiles and antibiogram patterns, showed that, several different clones of S. hyicus could be present simultaneously in vagina of gilts and also on skin of piglets. Generally isolates from the vagina of one animal were identical as regards to phage types, plasmid profiles, and antibiogram patterns during the entire investigation period. Isolates from the skin of piglets were of the same type as their mothers, indicating that vertical transmission had taken place. S. hyicus strains isolated from the skin of piglets within 24 h after birth were identical to strains isolated 3 weeks after birth from the same litter, indicating that the vaginal strains became part of a stable skin flora.
在健康繁殖母猪的阴道样本及其后代的皮肤样本中发现了较高的猪葡萄球菌定植率。在所检测的720株猪葡萄球菌分离株中鉴定出22种不同的噬菌体类型。每个猪群分离出2至13种不同的噬菌体类型。噬菌体分型以及通过质粒图谱和抗菌谱模式对约10%的分离株进行表征表明，猪葡萄球菌的几个不同克隆可能同时存在于后备母猪的阴道以及仔猪的皮肤上。一般来说，在整个调查期间，来自一只动物阴道的分离株在噬菌体类型、质粒图谱和抗菌谱模式方面是相同的。从仔猪皮肤上分离出的菌株与其母亲的菌株类型相同，表明发生了垂直传播。出生后24小时内从仔猪皮肤上分离出的猪葡萄球菌菌株与出生3周后从同一窝仔猪身上分离出的菌株相同，这表明阴道菌株成为了稳定皮肤菌群的一部分。
