Finding the MLST sequence type of an isolate

I want to find the MLST sequence type of Vibrio cholerae isolates based on their genome assemblies.

I find I can do it using the 'mlst' tool, described here.

To run it is very simple, e.g.

% mlst --scheme vcholerae assembly.fa

where assembly.fa is my assembly fasta file.

The output looked like this:

assembly.fa     vcholerae       338     adk(14) gyrB(36)        mdh(6)  metE(193)       pntA(11)        purM(1) pyrC(141)

That is, this isolate is ST338 in the Octavia et al MLST scheme for V. cholerae. Easy peasy!
