Abstract

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).
