The prevalence of colonization with the anaerobic intestinal spirochaetes Brachyspira aalborgi and Brachyspira pilosicoli was investigated in humans (n = 316) and dogs (n = 101) living on three tea estates in Assam, India. Colonization was detected using PCR on DNA from faeces. Nineteen (6%) human faecal samples contained B. aalborgi DNA, 80 (25.3%) contained B. pilosicoli DNA, and 10 (3.2%) contained DNA from both species. One canine sample contained DNA from B. pilosicoli. Significant factors for B. aalborgi colonization in logistic regression were: infection of family members with B. aalborgi (P < 0.001), being a resident of Balipara (P = 0.03), and use of water treatment (P = 0.03). For B. pilosicoli, significant factors were: other family members being positive for B. pilosicoli (P < 0.001), water obtained from a well (P = 0.006), water treatment (P = 0.03), and not having visited a doctor in the previous 12 months (P = 0.03).
在印度阿萨姆邦三个茶叶种植园生活的人类（n = 316）和狗（n = 101）中，对肠道厌氧螺旋体——奥尔堡短螺旋体和毛样短螺旋体的定植情况进行了调查。通过对粪便DNA进行PCR检测定植情况。19份（6%）人类粪便样本含有奥尔堡短螺旋体DNA，80份（25.3%）含有毛样短螺旋体DNA，10份（3.2%）含有两种螺旋体的DNA。一份犬类样本含有毛样短螺旋体DNA。逻辑回归分析中，奥尔堡短螺旋体定植的显著因素为：家庭成员感染奥尔堡短螺旋体（P < 0.001）、居住在巴里帕拉（P = 0.03）以及使用水处理（P = 0.03）。对于毛样短螺旋体，显著因素为：其他家庭成员毛样短螺旋体检测呈阳性（P < 0.001）、从井中取水（P = 0.006）、水处理（P = 0.03）以及在过去12个月内未看过医生（P = 0.03）。
