Comparing the DNA of B. mallei and B. pseudomallei must be done at the 23S rDNA level, however, since no identifiable difference is found between the two species at the 16S rDNA level.
A comparación do ADN de B. mallei e B. pseudomallei debe facerse co ADNr de 23S, xa que non hai diferenzas identificables entre as dúas especies no ADNr de 16S.
