Novel Primate Bocaparvovirus Species 3 Identified in Wild Macaca Mulatta in China.

ABSTRACT: Primate bocaparvovirus (BOV) is a possible cause of respiratory disorders and gastroenteritis in humans. However, the diversity and evolution of these viruses remain largely unknown, despite the identification of a growing number of BOVs in non-human primates (NHPs). Here, we report the identification of a novel BOV (provisionally named Macaca mulatta bocaparvovirus [MmBOV]) in the feces of wild Macaca mulatta in China by viral metagenomic analysis. Seven of 400 fecal samples from Macaca mulatta were positive for MmBOV. An almost complete genome sequence of 4,831 nucleotides was obtained, which had genomic organization and protein motifs similar to human bocaviruses (HOBVs), and shared characteristically low G/C content and weak codon usage bias. Sequence analyses of NS1, NP1, and VP1 revealed that MmBOV was most closely related to HBOV4 of Primate bocaparvovirus 2 (approximately 68.4%/70.6%, 73.3%/67.6%, and 70.4%/73.1% nucleotide/amino acid identities, respectively). Additionally, phylogenetic analysis revealed that MmBOV formed an independent peripheral branch, but clustered closely with those of the Primate bocaparvovirus species in the BOV genus (particularly HBOV4). These data strongly suggest that HBOV4 originated from NHP bocaparvoviruses around 200-300 years ago, and that NHPs may act as HBOV reservoirs. Following the International Committee of Taxonomy for Viruses guidelines, we propose MmBOV as a new species (tentatively named Primate bocaparvovirus 3) in the genus Bocaparvovirus, which is the first report of a novel species of primate BOV. Our data facilitate future research on the genetic diversity and evolution of primate bocaparvoviruses and highlight the importance of bocaparvovirus surveys in wild NHPs.

Project description:An array of 13 biochemically well defined molecular forms of bovine, human and newly cloned rhesus macaque (Macaca mulatta) AChEs (acetylcholinesterases) differing in glycosylation and subunit assembly status were subjected to comparative pharmacokinetic studies in mice and rhesus macaques. The circulatory lifetimes of recombinant bovine, macaque and human AChEs in mice were governed by previously determined hierarchical rules; the longest circulatory residence time was obtained when AChE was fully sialylated and tetramerized [Kronman, Chitlaru, Elhanany, Velan and Shafferman (2000) J. Biol. Chem. 275, 29488-29502; Chitlaru, Kronman, Velan and Shafferman (2001) Biochem. J. 354, 613-625]. In rhesus macaques, bovine molecular forms still obeyed the same hierarchical rules, whereas primate AChEs showed significant deviation from this behaviour. Residence times of human and rhesus AChEs were effectively extended by extensive sialylation, but subunit tetramerization and N-glycan addition had a marginal effect on their circulatory longevity in macaques. It appears that the major factor responsible for the differential pharmacokinetics of bovine and primate AChEs in macaques is related to differences in primary structure, suggesting the existence of a specific mechanism for the circulatory clearance of primate AChEs in rhesus macaques. The 35 amino acids that differ between bovine and primate AChEs are clustered within three defined domains, all located at the enzyme surface, and may therefore mediate the facilitated removal of primate cholinesterases specifically from the circulation of monkeys. These surface domains can be effectively masked by poly(ethylene glycol) appendage, resulting in the generation of chemically modified human and macaque AChEs that reside in the circulation for extraordinarily long periods of time (mean residence time of 10000 min). This extended residence time is similar to that displayed by native macaque butyrylcholinesterase (9950 min), which is the prevalent cholinesterase form in the circulation of adult macaques.
