Immunohistochemical evaluation of akabane virus infection in aborted and new-born calves
The present study was aimed at the detection and describing the lesions of akabane virus in foetal and new-born calves tissues using immunohistochemical and immunofluorescence techniques. Akabane virus lesions were evaluated in 12 foetuses and three new-born calves using serological and pathological methods and immunohistochemistry and immunofluorescence. Macroscopically, prominent arthrogrypos...
متن کاملAkabane virus infection.
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 arthrogryp...
متن کاملSeroprevalence and Risk factors of Akabane Virus Infection in cattle from Khouzestan Province of Iran
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...
متن کاملSerological and Molecular Detection of Akabane Virus in Iran
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...
متن کاملCongenital abnormalities in newborn calves after inoculation of pregnant cows with Akabane virus.
A fresh isolate of Akabane virus was inoculated intravenously into 11 seronegative pregnant cows at 62 to 96 days of gestation. Two of the cows were slaughtered 18 days post-inoculation, and the fetuses were examined; the remaining cows were allowed to give birth. All the inoculated cows developed viremia and neutralizing antibody for the virus, indicating that the cows were actually infected w...
