Abstract

Various genera of sulphate reducing bacteria (SRB) have been found in the human digestive tract. It is suggested that some of SRB species may be responsible for the development of the clinical symptoms of ulcerative colitis and other disease of large intestine. Sulphasalazine (salicyl-azo-sulphapyridine, SAS) is commonly used to treat patients with ulcerative colitis and Crohn disease. Above 30 samples of faeces or biopsy specimens from 25 patients (age 45 +/- 14 years; M/F, 13/12) suffering from gastrointestinal disorders were used for isolation of Desulfovibrio desulfuricans species. The morphological, physiological and biochemical characteristics of isolated strains and also their susceptibility to SAS was determined. D. desulfuricans isolates were obtained from 5 amongst all patients assayed. Some abnormal, cigar-shaped cells were detected as accompanying the cells represented by rods, curved rods and vibrios. After strains purification, two types of colonies were present on the solid Postgate's medium B (containing lactate as a carbon source and sulphate for energy conservation): the black colonies growing in bulk of agar medium and the transparent, surface-growing mucous colonies. These two types of D. desulfuricans colon...Continue Reading
