Bluetongue in Cattle and Sheep - NADI

  1. Bluetongue is a viral disease affecting sheep, cattle, deer, goats and camelids (camels, llamas, alpacas, guanaco and vicuña). Although sheep are most severely affected, cattle are the main mammalian reservoir of the virus and are very important in the epidemiology of the disease
  2. Blue Tongue in Sheep There are many strains of the virus causing blue tongue and immunity against one strain will not necessarily protect the animal against another. Lambs can get passive immunity suckling from an immune ewe. For this reason lambs of vaccinated ewes should not be vaccinated until they are weaned
  3. ants. Under field conditions, the causative agent, bluetongue virus (BTV), is typically transmitted by Culicoides spp. insects (biting midges) following a bite to consume a blood meal from susceptible animals. Mechanical transmission of the virus by other bloodsucking insects is of

Not all signs of blue tongue appear in a single sheep or even in a single outbreak. Best control methods involve controlling the gnat. Since this insect breeds in the mud along the edges of slow-moving streams or water tank overflow, try to eliminate these breeding sites. Breeding sites also can be sprayed with insecticides First aid for Bluetongue Disease in Sheep and Goats:- Separation of sick animals should be made. Affected animals should be kept away from solar exposure. Adequate rest to the affected animal Bluetongue (BT) is a non-contagious, viral disease affecting domestic and wild ruminants (primarily sheep and including cattle, goats, buffalo, antelope, deer, elk and camels) that is transmitted by insects, particularly biting midges of the Culicoides species. The virus which causes BT is identified as a member of the Reoviridae family The reason for reduced intake of feed and water are attributable to the pain factor associated by the ulceration of the gums and tongue caused by the bluetongue virus. Lectade (G361 Act 36/1947) is an electrolytic powder reconstituted with water used for reversal of dehydration, loss of electrolytes and energy

Bluetongue is generally regarded as an infectious insect-borne disease of sheep and other ruminants, but primarily affects sheep in its typical form. Although the susceptibility of goats and the occurrence of unapparent infections under natural conditions have been described many years ago, few studies have been conducted in these animals


Bluetongue: how to spot and report the disease. Bluetongue is a notifiable insect-borne viral disease that affects sheep, cattle, other ruminants such as goats and camelids such as IIasmas. It cannot be spread directly between animals and relies on the midge as a vector for transmission. It does not affected people or food safety, but outbreaks. Bluetongue virus can infect all ruminants (e.g. sheep, cattle, goats and deer) and camelids (e.g. llama and alpaca). Sheep are most severely affected by the disease. Cattle, although infected more frequently than sheep, do not always show signs of the disease. Find out more about the signs of bluetongue on NFUonline her Sheep and Goat Vaccine and Health Management Schedule. Most livestock vaccine and health management protocols revolve around the animal's stage of production. For sheep and goats, it is recommended to vaccinate prior to lambing, weaning, and breeding. The purpose of this publication is to offer a guide in establishing a health management.

Bluetongue (Midge-borne disease) Bluetongue is transmitted by the Culicoides midge, which breeds in moist, warm conditions, says Dr Leask. We have certain strains in SA and there are other strains in Europe. The strains in SA affect mostly sheep and although other species can get it, it is usually at subclinical levels 1. Introduction. Bluetongue (BT), an infectious, non-contagious and arthropod-borne virus disease of ruminants belonging to the family Reoviridae and the genus Orbivirus (Lefkowitz et al., 2018), culpable for an estimated annual loss of 3 billion US dollars.Clinical signs of BT are variable and usually detected in fine wool breeds of sheep and the white-tailed deer (Odocoileus virginianus. Bluetongue is well known by sheep farmers in the Karoo. The effects of the disease on Angora goats are less well known. Angora goats have been shown to be susceptible to experimental infections with bluetongue virus but apart from a fever reaction showed no clinical signs. Angora goats are susceptible to natural disease but certainly have.

Infection occurs by contact. The virus is highly resistant to desiccation in the environment, having been recovered from dried crusts after 12 yr. In the laboratory, it is also resistant to glycerol and to ether. Contagious ecthyma is found worldwide and is common in young lambs reared artificially and in older lambs during late summer, fall. Cattle, goats and elk, for example, are affected by a very mild, self-limiting infection. Bluetongue can cause serious illness and death in sheep as well as deer and potentially other wildlife. There is no cure and death may occur within seven days. In sheep, the symptoms of bluetongue include: fever. reddening of the lining of the mouth and nose Niki Foster Bluetongue disease is transmitted by biting midges.

Bluetongue (BT) is an emerging, infectious but non-contagious, viral disease of domestic and wild ruminants (primarily sheep and also goat, cattle, buffalo, antelope, deer, and camels), which is caused by bluetongue virus belonging to Orbivirus genus of Reoviridae family and is transmitted by biting midges of the Culicoides species (Mozaffari and Khalili 2012; Shlash et al. 2012; Purse et al. Bluetongue can be a severe disease in sheep with mortality varying from 5-80% depending on the virus serotype and on the immune status of the sheep populations. Although cattle can serve as reservoirs for BTV, clinical disease in cattle has generally been rare. When this has been encountered, clinical disease is usually evident in fewer than 5%. Occasionally, sheep will develop a swollen tongue with a bluish tinge caused by a lack of oxygen in the blood.. The term bluetongue is associated with severe rare cases where the mouth and nose swell so much that the tongue becomes almost blue in colour due to a reduced blood flow and severe swelling. In cattle the disease is less severe Bluetongue prevention measures stepped up. 21/08/06.

Introduction. Bluetongue (BT) is a non-contagious disease affecting ruminant and camelid species (Hofmann et al., 2008).BT, caused by Bluetongue virus (BTV), is a vectorborne disease transmitted between ruminant hosts by blood-feeding midges of the Culicoides spp.Hosts of BTV infection are domestic and wild ruminants, including sheep, goats, cattle and deer Bluetongue virus is an orbivirus and is a widespread pathogen of cattle in the United States and Africa and more recently has emerged as a problem in the Europe. It is thought to be responsible for significant economic losses approximating 125 million dollars a year. These recent outbreaks have proven to be very costly to the European cattle and sheep industry • Prevention involves good management practices and vaccination. Prevent conditions that can lead to the disease. A vaccine is available and could be used where the disease is important.
