Akabane virus infection.
نویسنده
چکیده
Akabane virus is a Culicoides-borne orthobunyavirus that is teratogenic to the fetus of cattle and small ruminant species. Depending upon the stage of gestation atwhich infection occurs, and the length of gestation of the mammalian host, a range of congenital defects may be observed. The developing central nervous system is usually the most severely affected, with hydranencephaly and arthrogryposis most frequently observed. Less commonly, some strains of Akabane virus can cause encephalitis in the neonate or, rarely, adult cattle. Akabane viruses are known to be widespread in temperate and tropical regions of Australia, Southeast Asia, the Middle East and some African countries. Disease is infrequently observed in regions where this virus is endemic and the presence of the virus remains unrecognised in the absence of serological surveillance. In some Asian countries, vaccines are used to minimise the occurrence of disease.

Abstract Background and Aims: Akabane disease causes epidemics of abortions, stillbirths and congenital malformations manifested as arthrogryposis and hydranencephaly or microanencephaly in sheep, goats and cattle. Akabane virus replicates in arthropods and is transmitted by either mosquitoes or midges. Outbreaks of the Akabane virus have been reported from many countries in Southeast Asia...

Background and Aims: Akabane virus is an arbovirus in the genus Orthobunyavirus of the family Bunyaviridae that can affect ruminants such as cattle, sheep and goats. This arthropod-borne virus is transmitted by either mosquitoes or midges and has been identified as a cause of outbreaks of reproductive disorders (abortions, premature births, and stillbirths) and congenital malformations (arthrog...

The present study was conducted on sixty healthy female domestic ruminants that suffered from still births or abortion, to find sero-positive cases and also to determine the probable role of uterine tissue in diagnosis of akabane viral infection and viral persistency. Because of this, a serological test (ELISA) and molecular (RT-PCR) diagnostic methods were used to find the seropositive cases a...
