AI Article Synopsis

  • In 2015 and 2016, researchers in Japan studied 15 malformed calves affected by Shamonda virus, which is part of the Simbu serogroup of viruses.
  • The calves exhibited noticeable symptoms such as arthrogryposis (abnormal joint development) and serious brain lesions.
  • The findings suggest that Shamonda virus should be recognized as a teratogenic virus, meaning it can cause developmental abnormalities in ruminant animals.

Article Abstract

In 2015 and 2016, we observed 15 malformed calves that were exposed to intrauterine infection with Shamonda virus, a Simbu serogroup orthobunyavirus, in Japan. Characteristic manifestations were arthrogryposis and gross lesions in the central nervous system. Our results indicate that this arbovirus should be considered a teratogenic virus in ruminants.

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

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.

Orthobunyaviruses (order , family ) in the Simbu serogroup have been responsible for widespread epidemics of congenital disease in ruminants. Australia has a national program to monitor arboviruses of veterinary importance. While monitoring for Akabane virus, a novel orthobunyavirus was detected.

Metagenomic analysis of and mosquitoes from diverse geographical regions of India revealed the presence of several insect viruses of human interest. Most abundant reads found in mosquitoes were of Phasi Charoen-like virus (PCLV), granulovirus (CfGV), Cell fusing agent virus (CFAV), and Wenzhou sobemo-like virus 4 (WSLV4), whereas WSLV4 and CfGV constituted the highest percentage of reads in viromes. Other reads that were of low percentage included Hubei mosquito virus 2 (HMV2), Porcine astrovirus 4 (PAstV4), and Wild Boar astrovirus (WBAstV).

Complete genome sequences of Sathuperi and Shamonda viruses isolated in Japan.

Sathuperi virus (SATV) and Shamonda virus (SHAV) (family Peribunyaviridae, genus Orthobunyavirus, species Schmallenberg orthobunyavirus) have been suggested to cause congenital abnormalities in ruminants. In this study, we determined the complete genome sequences of SATV KSB-6/C/02 and SHAV KSB-2/C/08 strains, which were obtained from Culicoides biting midges in Japan, by next-generation sequencing and Sanger sequencing. The 3'- and 5'-untranslated region sequences of the M segment of SHAV KSB-2/C/08 strains are distinctly different from those of SATV KSB-6/C/02 and Schmallenberg viruses.

Viruses in the genus, family, are associated with encephalitis, birth defects and fatalities in animals, and some are zoonotic. Molecular diagnostic investigations of animals with neurological signs previously identified Shuni virus (SHUV) as the most significant orthobunyavirus in South Africa (SA). To determine if other orthobunyaviruses occur in SA, we screened clinical specimens from animals with neurological signs, abortions, and acute deaths from across SA in 2021 using a small (S) segment Simbu serogroup specific TaqMan real-time reverse transcription polymerase chain reaction (RT-PCR).
