马红球菌是人类免疫缺陷病毒感染患者的一种新的机会致病菌。然而，目前对马立克氏杆菌在人类环境中的分布情况知之甚少。在本研究中，从日本115个公园和49码的土壤和沙子中采集的234份样本中，有173份(73.9%)分离到马立克氏杆菌。来自土壤和沙子的马立克氏杆菌数量在每克样品2.5×10(1)到1.2×10(5)之间。这些样本中的1294株分离物中没有一株显示出与毒力相关的15至17 kDa抗原和20 kDa抗原。这些结果表明，马立克氏杆菌在公园和庭院中普遍存在，但人类环境尚未受到毒力和中等毒力的马立克氏杆菌菌株的污染。
Rhodococcus equi is an emerging opportunistic pathogen of human immunodeficiency virus-infected patients. However, little is known about the distribution of virulent and intermediately virulent R. equi in human environment. In the present study, R. equi was isolated from 173 of 234 (73.9%) samples collected from soil and sand on 115 parks and 49 yards in Japan. The numbers of R. equi from soil and sand ranged from 2.5 x 10(1) to 1.2 x 10(5) per gram of sample. None of 1,294 isolates from those samples showed virulence-associated 15- to 17-kDa antigens and a 20-kDa antigen. These results suggest that avirulent R. equi is widespread in parks and yards, but the human environment has not been contaminated with virulent and intermediately virulent R. equi strains yet.
