References ↑ Boyle DB et al (2012) Genomic sequences of Australian bluetongue virus prototype serotypes reveal global relationships and possible routes of entry into Australia. BTV is a notifiable disease of ruminants, including sheep, cattle, deer, goats and camelids (camels, llamas, alpacas, guanaco and vicuña). Bluetongue virus is transmitted between its ruminant hosts by the bite of Culicoides spp. For the vaccination of healthy sheep and goats against type 10 bluetongue infections. Further the Regulation provides measures to be taken in case of suspicion of infection and in case of outbreak of the disease. Midges carry the bluetongue virus.

Bluetongue viruses are found world-wide and are transmitted by different Culicoides species in different regions. Bluetongue is caused by an Orbivirus with 24 serotypes and is transmitted by biting midges of the genus Culicoides.Historically, bluetongue occurred from approximately latitude 35°S to 40°N, except in the western USA, where it occurs to 45°N. It is transmitted by midges and can cause major economic losses in animal husbandry. Bluetongue virus contains 10 distinct genome segments in each viral particle. The annual economic damage in lost trade is in the millions of dollars. Although sheep are most severely affected, cattle are the main mammal reservoir of the virus and are critical in the disease epidemiology. It only rarely infects human beings. ... Prevention and control of the disease involves minimizing or eliminating exposure of livestoc k to theCulicoides-gnat during insect season. As the virus is found in the blood, there is the potential for spread by hypodermic needle or the equipment which is in contact with bodily secretions.

Bluetongue is a serious disease in cows, as well as other ruminant, and can have a significant impact on international trade. Infection with bluetongue virus (BTV) is common in a broad band across the world, which until recently stretched from ~35°S to 40°–50°N. Vaccines for Prevention of Bluetongue and Epizootic Hemorrhagic Disease in Livestock: A North American Perspective. Introduction. Diagnosis: By the presence of clinical signs similar to those reported in sheep have been documented in goats. But it will cause more instances of clinical problems in calves. The bluetongue virus (BTV) species contain 27 recognised serotypes and are most closely related to the viruses in the epizootic The disease mainly affects sheep. Slaughterhouses. In Fenner's Veterinary Virology (Fifth Edition), 2017. RESULTS: The serological evidence of Bluetongue virus infection was observed in 58 out of 299 cows, accounting for a 19.4% prevalence rate among cattle in North Kordufan State.

Sheep often have high morbidity with variable mortality, cattle morbidity is … J Virol 86(12):6724-6731 The BTV-8 strain of bluetongue circulating in France is likely to cause fewer clinical signs in adult cattle. Sheep often have high morbidity with variable mortality, cattle morbidity is … The number of diseases is large; the number of potential arthropod vectors involved is also large. Arthropod-borne diseases cause economic losses to the livestock industries of the United States and many other countries around the world. Recent changes in the epidemiology of Culicoides-transmitted viruses, … Bluetongue can affect domestic and wild ruminants. Bluetongue virus (BTV), a member of Orbivirus genus within the Reoviridae family causes serious disease in livestock (sheep, goat, cattle). There is no effective treatment for animals with Bluetongue apart from rest, provision of soft food, and good husbandry. 2. Measures on confirmation of the bluetongue virus. Bluetongue (BT) is an infectious viral disease of domestic and wild ruminants, caused by bluetongue virus (BTV).

Overwintering of BTV-8 and continuous low-level infections are assumed. Since there is no curative treatment for BTV-infected animals, prophylactic immunization of susceptible species remains the most effective and practical control measure against bluetongue in endemic regions. Bluetongue virus (BTV) is the type species of genus Orbivirus within family Reoviridae. Prevention; Outcomes; Introduction. Erasmus BJ.

This may include destroying insect habitat, use of insecticides, or moving bluetongue to be listed, Article 9 for the categorisation according to disease prevention and control rules as in Annex IV and Article 8 on the list of animal species related to bluetongue. Older cattle (>2 years of age) had four times the odds to be infected with BTV compared to young cattle (OR = 4.309, CI = 1.941-9.567, p-value = 0.01). Bluetongue virus (BTV) is the causative agent of bluetongue disease in sheep and cattle, an insect transmitted disease of ruminants (Erasmus., 1975). Today's proposal to amend Directive 2000/75/EC, expected to enter into force in 2011, updates current rules on vaccination.

Background: Bluetongue caused by the bluetongue virus (BTV) is a non-contagious and an insect-borne disease mainly affecting domestic and wild ruminants. Other gnats and bloodsuck-ing insects may occasionally transmit BT, but they are much less important in its transfer.

Etiology and Transmission: Clinical Findings: Diagnosis and Lesions: Prevention and Control: Merck and the Merck Veterinary Manual. Testing in animal health laboratories is necessary to distinguish between bluetongue and EHD-causing viruses. Bluetongue (BT) is a viral disease that is spread mainly by one specific type of gnat. Severe BT cases are characterized by symptoms including hemorrhagic fever, particularly in … Vaccination is the most effective means of prevention, but is expensive. A red to brown band around the coronet is an important diagnostic sign of bluetongue.

Although BTV has an African origin, it has been reported in the South of Europe since 1924 when it was first detected in Cyprus. Wooden tongue is a well-defined disease of the soft tissues of the mouth region in adult cattle. Moreover, no such data concerning BTV in Tibetan sheep is available. The infection is related to the climatic conditions of high temperatures and high humidity, which favor the proliferation of vectors. Outbreaks of BT can cause serious economic losses. But it will cause more instances of clinical problems in calves. Bluetongue cannot be naturally transmitted directly between animals. Bluetongue (BT) is a non-contagious disease affecting domestic and wild ruminants. PMID: 26086559. Prevention. Reemergence was confirmed by retesting the samples, experimental inoculation, fingerprinting analysis, and virus isolation.
