Abstract:
:We report the complete nucleotide sequence and characterization of a small cryptic plasmid of Moraxella macacae 0408225, a newly described bacterial species within the family Moraxellaceae and a causative agent of epistaxis in macaques. The complete nucleotide sequence of the plasmid pMoma1 was determined and found to be 5,375 bp in size with a GC content of 37.4 %. Computer analysis of the sequence data revealed five open reading frames encoding putative proteins of 54.4 kDa (ORF1), 17.6 kDa (ORF2), 13.3 kDa (ORF3), 51.6 kDa (ORF4), and 25.0 kDa (ORF5). ORF1, ORF2, and ORF3 encode putative proteins with high identity (72, 42, and 55 %, respectively) to mobilization proteins of plasmids found in other Moraxella species. ORF3 encodes a putative protein with similarity (about 40 %) to several plasmid replicase (RepA) proteins. The fifth open reading frames (ORF) was most similar to hypothetical proteins with unknown functions, although domain analysis of this sequence suggests it belongs to the Abi-like protein family. Upstream of the repA gene, a 470-bp intergenic region, was identified that contained an AT-rich section and two sets of tandem direct and indirect repeats, consistent with a putative origin of replication site. In contrast to other plasmids of Moraxella, the occurrence of pMoma1 in M. macacae isolates appears to be common as PCR testing of 14 clinical isolates from two different research institutions all contained the plasmid.
