AI Article Synopsis

  • Chuzan virus can cause serious congenital defects in cattle, including conditions like hydranencephaly and cerebellar hypoplasia in their calves.
  • A study in South Korea revealed that 4.4% of both free-ranging and farmed cervids tested positive for Chuzan virus antibodies.
  • This finding indicates that cervids in South Korea have been exposed to the Chuzan virus, highlighting a potential concern for their health and the livestock industry.

Article Abstract

Chuzan virus is teratogenic in cattle and causes congenital abnormalities, such as hydranencephaly and cerebellar hypoplasia, in calves. Chuzan virus seroprevalence among free-ranging and farmed cervids in South Korea was found to be 4.4% (38/873), confirming exposure to this virus in cervids in South Korea.

Searching for potential Culicoides vectors of four orbiviruses in Yunnan Province, China.

Parasit Vectors

February 2025

Yunnan Tropical and Subtropical Animal Virus Diseases Laboratory, Yunnan Animal Science and Veterinary Institute, Kunming, Yunnan, China.

Background: Some species of Culicoides (Diptera, Ceratopogonidae) are major vectors for arboviruses, and Yunnan Province is a key area for arbovirus prevalence in China. Therefore, this study attempts to search for potential Culicoides vectors for the common orbiviruses bluetongue virus (BTV), epizootic hemorrhagic disease virus (EHDV), Palyam virus (PALV) and Tibet orbivirus (TIBOV) in Yunnan Province, China.

Methods: Culicoides specimens were collected from 16 counties in Yunnan Province, China, using UV traps and tested for BTV, EHDV, PALV and TIBOV through one-step reverse transcription-quantitative polymerase chain reaction (RT-qPCR).

Emergence of a natural reassortant between Shamonda and Sathuperi viruses of the species Orthobunyavirus schmallenbergense in Japan.

Arch Virol

February 2025

Kagoshima Research Station, National Institute of Animal Health, National Agriculture and Food Research Organization (NARO), 2702, Chuzan, Kagoshima, 891-0105, Japan.

The whole-genome sequences of orthobunyaviruses isolated from cattle reared on Yonaguni Island (the western-most point of Japan's territory) were determined. The sequences of their S and L RNA segments were observed to be almost identical to those of Shamonda virus (SHAV) isolates identified in Japan, whereas the sequences of their M RNA segments were very similar to those of Japanese isolates of Sathuperi virus (SATV). Our findings indicate that the two novel isolates are natural reassortants between SHAV and SATV, which share a genome segment organization similar to that of Schmallenberg virus.

Article Synopsis
  • Researchers sequenced the genomes of 15 strains of Palyam serogroup virus (PALV) from cattle and biting midges in Japan, revealing multiple virus types including Chuzan (CHUV) and D'Aguilar virus (DAGV).
  • The analysis showed that Japanese Marrakai virus (MARV) strains from 1997 are genetically related to both Australian PALVs and other Japanese strains, indicating these MARV strains are reassortants between different viral lineages.
  • A new real-time PCR assay was developed for detecting PALV, and it successfully identified the DAGV gene in bovine stillborn fetuses, marking a significant first in identifying PALV in this context outside of Australia and Africa

Replication of Akabane virus and related orthobunyaviruses in a fetal-bovine-brain-derived cell line.

Arch Virol

June 2024

Kagoshima Research Station, National Institute of Animal Health (NIAH), National Agriculture and Food Research Organization (NARO), 2702 Chuzan, Kagoshima, Kagoshima, 891-0105, Japan.

Akabane virus (AKAV), Aino virus, Peaton virus, Sathuperi virus, and Shamonda virus are arthropod-borne viruses belonging to the order Elliovirales, family Peribunyaviridae, genus Orthobunyavirus. These viruses cause or may cause congenital malformations in ruminants, including hydranencephaly, poliomyelitis, and arthrogryposis, although their pathogenicity may vary among field cases. AKAV may cause relatively severe congenital lesions such as hydranencephaly in calves.

Article Synopsis
  • - Whole-genome sequencing of a virus from biting midges in Japan identified it as a strain of Balagodu virus (BLGV), related to Orthobunyavirus.
  • - This virus was previously isolated only once in India in 1963, and the Japanese strain shows complete protein-coding sequences similar to other viruses in the same family.
  • - The study enhances our understanding of BLGV's geographic distribution and offers a complete genomic sequence, aiding in the classification of related viruses.
