Whole-Genome Sequencing of Three M. gallisepticum Isolates Similar to the 6/85 Vaccine Strain

Effective control of Mycoplasma gallisepticum infection is accomplished through vaccination with live attenuated vaccines. However, virulent M. gallisepticum strains with genetic markers consistent with those of vaccine strains were found in infected flocks. We report here the complete genetic sequences of three isolates that are genetically similar to the 6/85 vaccine strain.
