Abstract

Mycoplasma testudineum is one of the pathogens that can cause upper respiratory tract disease in desert tortoises, Gopherus agassizii. We sequenced the genome of M. testudineum BH29T (ATCC 700618T = MCCM 03231T), isolated from the upper respiratory tract of a Mojave desert tortoise with upper respiratory tract disease. The sequenced draft genome, organized in 25 scaffolds, has a length of 960,895 bp and a G + C content of 27.54%. A total of 788 protein-coding sequences, six pseudogenes and 35 RNA genes were identified. The potential presence of cytadhesin-encoding genes is investigated. This genome will enable comparative genomic studies to help understand the molecular bases of the pathogenicity of this and other Mycoplasma species.

Keywords: Desert tortoise; Gopherus; Mycoplasma testudineum; URTD; Upper respiratory tract disease.

Phylogenetic tree of the Mycoplasma genus based on 16S rRNA gene sequences showing the phylogenetic position of M. testudineum BH29T (●). All 16S sequences from the Mycoplasma genus were obtained from the SILVA database [17]. Only sequences in the ‘The All-Species Living Tree’ Project (LTP), release 128, were retained. This dataset only contains sequences from type strains, designated with a superscripted “T”. Clostridium botulinum strain ATCC 25763 was also included in the dataset as outgroup. Sequences were aligned using MUSCLE 3.8.31 [18]. A phylogenetic tree was obtained using the maximum likelihood method implemented in MEGA7 [19], with 1000 bootstrap replicates. Species with available genomes at the NCBI Genomes database or the Genomes Online Database are represented in bold face. GenBank accession numbers are shown in parentheses. Bootstrap support values above 50% are represented. The scale bar represents a divergence of 0.05 nucleotide substitutions per nucleotide position
