As seen in this investigation, this approach can be inconclusive, and phylogenetic analysis of sequences including housekeeping genes might be required.
For these strains, sequencing and comparing housekeeping genes between maculicola pathovars, will point the genetic conservation between them or could establish the identity of another pathovar.
Housekeeping genes 18S ribosomal RNA (18S rRNA) and elongation factor-1 alpha (EF1) were used as the internal control genes.
