To confirm additional changes in biotype attributes in the variant Kolkata isolates during 2003-2014, we used the Voges-Proskauer test to determine production of acetylmethyl carbinol and found that the tested strains produced acetoin and were positive for chicken erythrocytes agglutination.
The isolate was found to be positive for enteric bacteria in the Voges-Proskauer test and resistant to polymyxin B (50 units).
In addition, the 37 clinical isolates were identified as El Tor 01 on the basis of Voges-Proskauer tests and were positive for [hlyA.
