Analysis of Clostridium Difficile in Drinking Water Treatment Intake in Canada
The objective of this study was to determine the distribution of Clostridium difficile contamination in drinking water treatment intake in the Grand river. C. difficile was found in 85％ (17/20) of all samples. Isolates showed a high diversity and were grouped into 9 different PCR ribotypes. PCR ribotype 078 was the predominate type (33.3％ of all isolates), which was found in food animals and other foods. The isolates showed different ribotypes, which came from different sampling times. The results suggested multiple different sources contaminated the drinking water treatment intake in the Grand River during sampling period. Animal was an important contamination source. At the same time, the results indicated C. difficile can be disseminated via water throughout the environment.
