library from ongoing statewide assessments. Seventeen (49%) of the unknown E. coli isolates matched isolates from raccoon and deer scat from the local library. Two isolates (6%) were matched with monkey sources from Morgan Island, and 13 (37%) were matched to raccoon, deer, and cows from the statewide assessment. Evaluation of repeated ribotyping analyses at the study area revealed evidence of temporal variability of potential sources in the local library. Only one of the isolates from the second year of fecal samples successfully matched with a fecal isolate from the previous year. The results from this study suggest that source identification results were variable both spatially and temporally, and that local, temporally specific libraries are most appropriate for library-based MST studies in small watersheds. Results also suggest thatJeremy Corbyn's team have used an IBTimes UK video without authorisation in a tweet to attack Liberal Democrat leader Tim Farron on Friday (20 January).

The 'ripped' footage, in which Farron fails to rule out going into a coalition government with the Conservatives again, was posted on the Labour leader's official verified Twitter account @JeremyCorbyn.
