Complete Genome Sequences of Two Rat Pegivirus Strains in Indonesia.

The entire genome sequences of two pegivirus strains recovered from serum samples of wild rats (Rattus rattus) in Indonesia were determined. They possessed 11,013 to 11,014 nucleotides and differed from the reported rodent pegivirus strains within the Pegivirus J species of the genus Pegivirus by 12.7% to 40.9% in the near-entire coding region sequences.

Identification and full-genome characterization of novel circoviruses in masked palm civets (Paguma larvata).

The family Circoviridae comprises a large group of small, circular, single-stranded DNA viruses and is classified into two genera: Circovirus and Cyclovirus. They have marked genetic diversity and a broad host range. In this study, three novel circovirus genomes were identified from wild-caught masked palm civets (Paguma larvata) in Japan and classified as a new species within the genus Circovirus based on the demarcation criteria of the International Committee on the Taxonomy of Viruses. Of note, the presence of two predicted introns at the 5'-terminus of the rep gene was suggested in the Paguma larvata circovirus genomes.

Identification and whole genome characterization of novel anelloviruses in masked palm civets (Paguma larvata): Segregation into four distinct clades.

The members of the family Anelloviridae are small and single-stranded DNA viruses with marked diversity in sequence and length, which ubiquitously infect many vertebrates, including mammals, birds and reptiles. The anelloviruses isolated from mammals are currently classified into 11 assigned and four proposed genera; some anelloviruses remain unassigned. The present study was conducted to identify anelloviruses in wild-caught masked palm civets (Paguma larvata) in Japan using a rolling-circle amplification method. Thirteen novel anellovirus strains were identified from 8 of 10 masked palm civets and their entire genomic sequences (2039-2535 nucleotides) were determined; they were classifiable into four distinct clades. Comparative analyses of all reported anelloviruses for which the entire or near-entire genomic sequences have been determined, including the 13 strains obtained in the present study, revealed that anelloviruses can provisionally be classified into 20 clades, which may correspond to 20 genera (including 11 assigned and four proposed genera) by a >70% amino acid sequence difference in open reading frame 1 (ORF1). This study suggested that novel anelloviruses of marked diversity are circulating in animals worldwide, and that the rolling-circle amplification method would be useful for identifying novel anelloviruses and other viruses with a circular DNA genome.

[A case of femoral neuropathy after radical ovariectomy].

We experienced a 55-year-old female patient who was diagnosed as femoral neuropathy after radical ovariectomy. An epidural catheter was introduced at T11-12 interspace without any problems and general anesthesia was induced and maintained. The operation ended uneventfully. On the first postoperative day, she noticed hypesthesia of the inner surface of her left thigh and could not raise the left leg. The symptom remained after the removal of epidural catheter on the second postoperative day, and the influence of insertion of the epidural catheter on the symptom was suspected. We performed neurological examinations and found weakness of the left quadriceps femoris muscle, weakness of the left patellar reflex, and weakness of touch sensation and cold sensation and hypalgesia on the anterior surface of the left thigh and the inner surface of the left lower leg. Those findings led us to diagnose with femoral neuropathy probably due to abdominal retractors or the operation itself, and insertion of epidural anesthesia could not be the cause of neuropathy. Her symptom was ameliorated with a conservative therapy after four months. We should perform fine neurological examinations when neurological complications occur, especially when we use epidural catheters, and also should have the knowledge about those complications.
