“…The seroprevalnce of 60.53 and 69.1% in caprine and ovine, respectively in our study was lower than that study of Mulabbi et al (2013) reported 90% seroprevalence in goats in Uganda. There were similar studies and findings by Yousef et al (2012) who reported seroprevalence of 54.1% and 53.3% in sheep and goats, respectively, in Saudi Arabia. Different studies show that bluetongue virus infection widely distributed and reported from many countries in the world including Turkey 29.5% by Gur (2008), India 45.7% by Sreenivasulu et al (2004), Pakistan 48.…”

Bluetongue is an infectious, a non-contagious, arthropod borne viral disease of ruminants and has been reported from most of the tropical and subtropical regions of the world. Seroprevalence study was carried from July, 2013 to January, 2015 to understand bluetongue virus infection in selected areas of sheep and goats found in and around small ruminant breed improvement center. A total of 1420 sera samples from sheep and goats were collected and screened for the presence of group specific bluetongue virus antibody using competitive Enzyme-Linked Immuno-Sorbent Assay(c-ELISA) with sensitivity of 100% and specificity of 99%. The overall seroprevalence of bluetongue virus antibody was 69.01% and 60.53% in sheep and goats, respectively. Seroprevalence of bluetongue ranges from 14.5% (Adami Tulu Research Center) to 91.43 % (Benestemay). Antibody to bluetongue virus was detected from both sheep and goats in all study areas. Result of this study showed that small ruminant dwelling in and around the small ruminant breed improvement centers are exposed to bluetongue virus. In the present study areas there were no observation of clinical cases in any species of animals. This indicates that local breed of animals are resistant to clinical disease of bluetongue infection and or there may be circulation of mild virus strain in the population and so further studies are required to determine the bluetongue serotypes that are circulating in sheep and goats.

“…In addition, Kassala state shares long international borders with Eritrea with no strict restriction on animals' movement across the borders which may allow introduction of infected animals into the localities. Similar high seroprevalence of BTV infection in various animal species was reported in several states in Sudan [ 28 , 29 , 31 , 36 , 39 ] and in countries around or near Sudan such as Libya (48.4%) [ 44 ]; Egypt (16.9%) [ 45 ]; Ethiopia (30.6%) [ 42 ]; and Saudi Arabia (47.3%) [ 46 ]. In addition, earlier epizootiological surveys also showed high prevalence rates for BTV seropositivity in Iran (93.5%) and Southern Turkey (88%) [ 47 , 48 ].…”

Bluetongue (BT) is an infectious, noncontagious, vector-borne viral disease of wild and domestic ruminants. BTV is a member of the Orbivirus genus of the family Reoviridae. The present study aimed to investigate the seroprevalence of BTV in sheep and goats in Kassala State, Sudan. It also aimed to determine risk factors associated with BTV infection. The study was carried out by a structured questionnaire survey, and a total of 809 serum samples were collected from sheep (n = 459) and goats (n = 350) from 9 different localities in Kassala state. These samples were analyzed using a competitive enzyme-linked immunosorbent assay (cELISA) for the detection of BTV antibodies. The overall seroprevalence of BTV was 91.2% (738/809). In goats, the prevalence of BTV antibodies was comparatively higher (100%) than in sheep (84.5%). The prevalence differed between localities and was the highest in the center section of Kassala and Western Kassala (100%). Animals aged 6–11 months were highly infected (93.9%) compared to 1-year-old (85.5%). Caprine species was more likely to be infected (100%) than ovine (84.5%), and females were highly infected (92.8%) than males (85.5%). BTV infections were higher in the winter season (91.4%). Risk factors that showed significant associations with cELISA positivity included locality and sex (p≤0.003) and species and age (p≤0.000). Factors significantly associated with cELISA positivity in multivariate analysis were localities, species, age, and sex. BTV infection is prevalent in sheep and goat populations in Kassala state.

“… 20 In this study, the prevalence rate of BT antibodies in sheep was 40.87%. In other countries, the prevalence was as follows: 21.40% in Kazakhstan, 6 29.59% in southeastern Turkey, 14 62.69% in India, 21 54.10% in Saudi Arabia, 22 and 48.70% in Pakistan. 16 Climatic factors play an important role in the occurrence of BTV infection in animals and influence the size of vector populations and periods of their seasonal activity.…”

The objective of this study was to describe the seroprevalence rates of bluetongue virus (BTV) in sheep in west and northwest provinces of Iran. Bluetongue virus, an economically important orbivirus of the Reoviridae family, causes a hemorrhagic disease mainly in sheep and occasionally in cattle and some species of deer. Bluetongue virus is transmitted between its mammalian hosts by certain species of biting midges (Culicoides spp.) and it can infect all ruminant species. Overall, 26 serotypes have been reported around the world. Due to its economic impact, bluetongue (BT) is an Office of International des Epizooties (OIE)-listed disease. A total of 756 sera samples collected during 2007-2008, were available. Sera were tested with competitive enzyme-linked immunosorbent assay (C-ELISA). The seroprevalence rate in sheep was 40.87%. The rate of positivity in sheep in west and northwest was 46.10% and 33.75%, respectively. The highest prevalence of antibodies in serum was in West Azerbaijan (64.86%), and lower was in Ardabil (23.77%).
