Reclassification of Mesoplasma pleciae as Acholeplasma pleciae comb. nov. on the basis of 16S rRNA and gyrB gene sequence data

Abstract

Genomic DNA sequence data for the 16S rRNA gene and the gyrB gene Mesoplasma pleciae PS-1T (=ATCC 49582T =NBRC 100476T) demonstrate a much closer relationship to Acholeplasma laidlawii and Acholeplasma oculi than to other species in the order Entomoplasmatales. In addition, the preferred use of UGG rather than UGA as the codon for tryptophan in the gyrB sequence probably places the organism outside the order Entomoplasmatales. It is proposed that M. pleciae be reclassified in the genus Acholeplasma, as Acholeplasma pleciae comb. nov. © 2004 IUMS.
