Genome Sequences of Mycoplasma alligatoris A21JP2T and Mycoplasma crocodyli MP145T
J Bacteriol. 2011 Apr 01;
Mycoplasma alligatoris and Mycoplasma crocodyli are closely-related siblings, one being highly virulent and the other relatively attenuated. We compared their genomes to better understand the mechanisms and origins of M. alligatoris' remarkable virulence amid a clade of harmless or much lower-virulence species. Although its chromosome was refractory to closure, M. alligatoris differed most notably by its complement of sialidases and other genes of the N-acetylneuraminate scavenging and catabolism pathway.
