RABIES IN CATTLE.

This is usually diagnosed in dogs and sometimes cats in this part of the world, with particular reference to dogs running wild and biting people.The virus can affect other animals such as horses,foxes,skunks,bats and cattle,but the usual suspect is the dog. A bite from an infected wild animal, such as a fox or raccoon, is a common method of infection in cattle. In Europe, rabies in dogs is a growing concern,in Africa the threats come from Jackals and in Northern Europe, Wolves are a prime vector of the virus. The skunk is the most likely carrier that spreads the disease to domestic animals such as dogs, cats, horses and cattle and those species then will show the clinical signs of rabies. The rabies virus is spread through the saliva of a positive animal, and when bitten by a positive animal is the primary way the virus is spread. However, other methods of spreading the disease are saliva from a positive animal getting into an open wound, or saliva from a positive animal getting into a mucus membrane – the eyes, gums or lips – of another animal or human.The time between infection and the onset of clinical signs varies. It can range from as early as a few weeks to as late as a few months after infection. Infected animals will start to carry the virus in their saliva before they start to show clinical signs, and this is why the rabies virus is different than most other viruses, because it does not enter the bloodstream but rather, the rabies virus travels through the nerves from the point of infection. If an animal is bitten on its back leg, the rabies virus will travel through the nerves of the back leg to the spinal cord, and then from the spinal cord, it will go to the brain and When this happens the clinical signs become obvious. An animal that is bitten on the nose, as it is believed most cattle are, will start showing clinical signs earlier than an animal bitten on the back leg. This is because the virus has less distance to travel to the brain and this accounts for the time variation between being infected and showing clinical signs.Once an animal shows clinical signs, typically within four to five days that animal will get progressively worse and die. There are effective rabies vaccinations available for humans, dogs, cats, horses and cattle. Veterinarians recommends that producers who show cattle consider vaccinating those cattle for rabies. If those show animals contract rabies, there is more of a chance of exposure to humans.While it isn’t always practical to vaccinate the whole cow herd, vaccination in prevalent areas are encouraged.

RABIES IN HORSES.

Equine rabies is a feared and fatal disease, but there are ways horse owners can reduce the risk of their animals becoming infected.Rabies is fatal to all mammals. Rabies--caused by a lyssa virus that affects mammals' nervous system and salivary glands. It has six genotypes, all of which have different host ranges and pathogenicities. Rabies is everywhere,but more prevalent in underdeveloped countries than others.There are some countries reported free of the virus include Australia, Great Britain, New Zealand, Scandinavia, and Switzerland. ROUTES OF INFECTION IN HORSES. 1)Horses contract rabies from other infected animals. The horse will contract the rabies virus, when bitten by another rabid animal or have a wound contaminated with saliva or blood from an infected animal. 2) Wildlife exposure and interaction. The sylvatic cycle of the rabies virus is maintained by the wildlife community,thus when there is an interaction especially through fights,bites or consumption of infected carcass,the virus spreads. The animals that usually harbour the virus are skunks,foxes,bats,wild dogs and livestock. SIGNS OF RABIES.The signs at onset are nonspecific and include ;depression,inappetence, and Ataxia.The signs become more pronounced as the infection progresses and these are 1) hypersensitivity tu sound and touch. 2) pruritis 3) increased libido 4)twitching. Rabies is rapidly progressive and uniformly fatal with death from cardio-respiratory failure or misadventure within 10 days .People exposed to blood or saliva from a rabid horse has a risk of contracting and therefore dying of rabies,although the chances of infection from a horse to a human are small ;all prevention protocols should be observed. BIOSECURITY IN CASES OF RABIES.1) If any animal is suspected,there must be isolation of subject and restriction of handlers to the box. 2)The use of gloves,face mask and protective clothing. Vaccination is still the best means of protection.Vaccinate all horses.
