Characterization of atypical Mycoplasma anserisalpingitidis strains

Mycoplasma anserisalpingitidis is a waterfowl colonizing mycoplasma, mainly found in geese. In this study, we compared the whole genomes of five atypical M. anserisalpingitidis strains originating from China, Vietnam and Hungary, with the rest of the collection. Common methods used in the description of species are genomic analyses like the analysis of 16 S - intergenic transcribed spacer (ITS) - 23 S rRNA, of housekeeping genes, of the average nucleotide identity (ANI) and average amino acid identity (AAI) and phenotypic analyses like testing the growth inhibition and the growth parameters of the strains. The atypical strains showed notable genomic differences in all of the genetic analyses: on average ANI and AAI 95% (M. anserisalpingitidis ANI Minimum: 92.45, Maximum: 95.10; AAI Minimum: 93.34, Maximum: 96.37). The atypical strains formed a separate branch among the M. anserisalpingitidis strains in all phylogenetic studies. The small genome size and possibly higher mutation rate of the M. anserisalpingitidis species likely contributed to the observed genetic difference. Based on genetic analyses, the studied strains clearly represent a new genotype of M. anserisalpingitidis. The atypical strains showed slower growth in the medium containing fructose and three of the atypical strains showed diminished growth in the inhibition test. However, no definitive geno-phenotype associations were found regarding the fructose metabolism pathway in the atypical strains. The atypical strains are potentially at an early stage of speciation.
