The IMViC tests are a group of individual tests used in microbiology lab testing to identify an organism in the coliform group. A coliform is a gram negative, aerobic, or facultative anaerobic rod, which produces gas from lactose within 48 hours. The presence of some coliforms indicate fecal contamination. The term "IMViC" is an acronym for each of these tests. "I" is for indole test; "… Witryna13 kwi 2024 · The IMViC series of tests (indole, methyl red, voges-proskauer, and citrate utilization )can be used. The enteric organisms are subdivided as lactose fermenters and nonfermenters. Escherichia coli, Enterobacter aerogenes, Klebsiella pneumoniae are lactose fermenters.
