Sheep are susceptible to at least 5 of the 10 flaviviruses known to be present in South Africa. Sheep, 7-9 months of age, injected with Wesselsbron, West Nile, Banzi, Uganda-S and AR 5189 (an unidentified virus related to Banzi and Uganda-S), responded with a moderate febrile reaction, a low grade viraemia of short duration and the production of virus neutralizing antibodies. The most pronounce...

Bluetongue is an arbovirus that affects different animal species, being most relevant in sheep because of the possible disease severity. This study aimed to evaluate occurrence antibodies against bluetongue virus (BTV) central-western region Paraná, Brazil, and risk factors for infection species. first determine these southern Brazil. A serological survey using agar gel immunodiffusion was posi...

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...

BACKGROUND: Toxoplasmosis is one of the most prevalent parasitic diseases in human societies and ani- mal populations, particularly pregnant women and domestic animals. This life-threatening infection may cause severe consequences in the fetus. OBJECTIVES: This study was aimed to estimate the prevalence of anti-parasite antibodies in pregnant wom- en and sheep and goat populations of Zabol city...

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, middle east,...

Sheep and goat pox is highly devastating viral systemic disease of sheep and got. This disease is manifested by skin and internal lesions, fever, conjunctivitis, with oculonasal discharge and excess salivation. The objective of this paper was to review epidemiology and economic importance sheep and goat pox with special emphasis on both the past and currents aspects. The causative agent of Shee...

The aim of the present study was to determine the serological and virological status of animals persistently infected (PI) with border disease virus (BDV), with focus on the prevalence of pestiviruses in sheep and lambs. This study is the first to our knowledge, to investigate the role of viral infections in abortions in the sheep population of Konya province. The prevalence of antibodies again...
