Seroprevalence of Visna-Maedi Virus (VMV) and Border Disease Virus (BDV) in Van province and around

Abstract

The present study investigated the seroprevalance of Visna Maedi Virus (VMV) and Border Disease Virus (BDV) infections in sheeps in regions in and around Van province, Turkey. Sample materials were taken from 360 sheep sent to slaughterhouses around Van. All serum samples were examined using ELISA for antibodies for Visna Maedi (VMV) and Border Disease (BDV) viruses. Of these, 38 (10.5%) tested positive for Visna Maedi virus antibodies and 163 (45.2%) for Border Disease virus antibodies. Varying numbers of samples were positive for both virus antibodies across the towns of Erciş, Çaldıran, Erçek and Başkale in Van, Ağrı and Hakkari provinces. Both infections should be eliminated by informing veterinarians and animal owners, identifying and eliminating persistently infected animals from flocks, and conducting appropriate eradication measures. Economic support should be provided for this.

Investigation of the Epidemiology of Small Ruminant Lentivirus Infections southeast part of the Marmara region of Turkey

“…In Turkey, the disease was reported for the first time by Alibaşoğlu and Arda (1975) at a rate of 0.02% in animals slaughtered in slaughterhouses in various provinces, and the researchers found seropositivity at a rate of 0.94% in the samples obtained from slaughterhouses in Istanbul (Yılmaz et al, 2002), 5.29% in Şanlıurfa and its surroundings (Ün et al, 2018), and 10.5% in Van and its surroundings (Ameen and Karapınar, 2018). The researchers detected the presence of Maedi-Visna specific antibodies at a rate of 2.9% in the sheep population sampled in Konya and its surroundings (Yavru et al, 2012), at a rate of 1.5% in Erzurum province and its surroundings (Schreuder et al, 1988), at a rate of 5.7% in Afyonkarahisar (Arık et al, 2015), at a rate of 23.5% in the Black Sea region (Albayrak et al, 2012), at a rate of 7.69% in the Eastern Mediterranean region (Doğan et al, 2021), and at a rate of 16% in Kars and its surroundings (Gezer et al, 2021).…”

Detection of Maedi-visna virus in sheep in Nineveh province

“…The presence of seropositive sheep within herds can be explained by the importation of feedlot sheep, poor quarantine measures, the lack of monitoring of sheep flocks to and from unobserved fringe seropositive Maedi-visna virus polities, and contact between unhealthy and healthy animals. This study was conducted in the presence of Maedi-visna virus infection in the polities adjoining Iraq (Iran, Turkey, and Syria) (4,22).…”
