There are few reports in the literature about the isolation of bacteria from whale intestine. In this report, we counted colony-forming units in the feces obtained from three female common minke whales (Balaenoptera acutorostrata). The number of colony-forming units ranged from (2.2+-0.4) x 10E5 to (8.9+-2.0) x 10E8 per gram (wet weight) of excrement. 16S rRNA gene sequences of 141 isolates were determined. These strains were identified as Enterococcus faecalis, Enterococcus sp., Enterobacter cloacae, Enterobacter sp., Escherichia coli, Edwardsiella ictaluri or Clostridium sp. The data suggested that the facultative anaerobic population of the intestinal bacterial flora of the minke whale was similar to that of ground mammals.
