Abstract

Mycoplasma ovipneumoniae is an important etiological agent of sheep respiratory disease worldwide. Here, we describe the first isolation and draft genome sequence of M. ovipneumoniae strain USP-BR2017 retrieved from tracheobronchial lavage of a sheep showing clinical signs of respiratory disease in the Rio de Janeiro State, Brazil. The culture of tracheobronchial lavage resulted in glucose-fermenting fried egg colonies, which were identified as M. ovipneumoniae by polymerase chain reaction. The genome was sequenced using the Illumina NextSeq 2000 and de novo assembled using SPAdes. The genome of the sequenced organism presented an approximate size of 1,122,253 bp. The annotation revealed 773 coding DNA sequences (CDSs), 806 genes, three rRNAs, and 30 tRNAs. Data analysis revealed M. ovipneumoniae strain USP-BR2017 contains a few virulence genes, including the hemolysing C gene (hlyC). In addition, strain USP-BR2017 showed high identity over the 16S rRNA gene with other sheep isolates from China and United States. This first description of M. ovipneumoniae in diseased Brazilian sheep demonstrates the importance of continuous surveillance and diagnostics of pathogens causing respiratory disease in sheep in Brazil.
