The occurrence of Mycoplasma hyosynoviae at different locations of the upper respiratory tract and tonsils of pigs was investigated in herds with problems of arthritis apparently caused by this microorganism. The isolation of M. hyosynoviae was facilitated by the use of a medium selectively suppressing the growth of Mycoplasma hyorhinis. M. hyosynoviae was cultured from 106 of 178 tonsils of slaughterhouse pigs from 8 herds but could not be isolated from the mucosa of the nasal cavity or the oral-pharyngeal area of 100 living, 10-20 weeks old pigs in 5 of the herds. The value of the selective principles in the medium appears from the circumstance that 86 of the 106 isolates were obtained despite the presence of M. hyorhinis. It is concluded that the tonsil is a reservoir for M. hyosynoviae and is probably the location of choice for an easy demonstration of the presence of this mycoplasma in a pig herd.
在明显由猪鼻支原体引起关节炎问题的猪群中,研究了猪鼻支原体在上呼吸道不同部位及扁桃体中的存在情况。使用一种能选择性抑制猪鼻支原体生长的培养基有助于分离猪鼻支原体。从8个猪群的178头屠宰猪的扁桃体中,有106个培养出了猪鼻支原体,但在其中5个猪群的100头10 - 20周龄活猪的鼻腔黏膜或口咽区域未分离到该菌。尽管存在猪鼻支原体,但106个分离株中有86个是通过该培养基的选择性原理获得的,这表明了该培养基选择性原理的价值。得出的结论是,扁桃体是猪鼻支原体的储存库,可能是在猪群中轻松证明该支原体存在的首选部位。
