Ureaplasmas were detected in the saliva of 3.5 per cent (12/342) of subjects. A total of 60 isolated strains did not revert to bacterial forms on repeated subculture in antibacterial agent-free media, failed to grow in serum-free media, were inhibited by digitonin and hydrolysed urea but not glucose or arginine. Twenty-five strains were divided into serotypes: I (5), II (3), III (5), IV (4) and VI (8 strains). Ureaplasmas of serotype I, II, III, IV and VI were harboured by 2, 1, 1, 1 and 3 subjects respectively and the remaining 4 subjects harboured 2 different serotypes. Ureaplasma-positive subjects were young and middle-aged and, except for 1 subject with mandibular arthrosis, suffered from periodontitis, pericoronitis, gingivitis and maxillary sinusitis. These accounted for only 6.1 per cent (11/180) of the series of subjects examined.
在3.5%（12/342）的受试者唾液中检测到脲原体。总共60株分离菌株在不含抗菌剂的培养基中反复传代培养时未回复为细菌形态，在无血清培养基中无法生长，被洋地黄皂苷抑制，能水解尿素但不能水解葡萄糖或精氨酸。25株菌株被分为不同血清型：I型（5株）、II型（3株）、III型（5株）、IV型（4株）和VI型（8株）。I型、II型、III型、IV型和VI型脲原体分别存在于2名、1名、1名、1名和3名受试者体内，其余4名受试者携带2种不同血清型。脲原体阳性受试者为中青年，除1名患有下颌关节病的受试者外，均患有牙周炎、冠周炎、牙龈炎和上颌窦炎。这些仅占所检查受试者系列的6.1%（11/180）。
