The canine rabies
By: Dogs
The canine rabies is a disease present in all continents and is caused by a virus of the family Rhabdoviridae.
Although all mammals can be infected with the rabies virus, dogs are the main transmitters of the disease in the world.
The only places in the world where there is no rabies virus are Australia, the British Isles and Antarctica. Apart from these places, the rabies virus exists anywhere else in the world.
This disease is fatal and can affect human beings. Therefore, all countries take measures to prevent, contain and try to eliminate it.
Transmission of canine rabies
The canine rabies is transmitted through the saliva of an infected animal. Normally this happens through a bite, but some have been documented cases where the rabies virus has been transmitted in aerosol particles floating in the air. These cases, however, are strangers and only have happened in many inhabited caves where bats infected.
The most common carrier of rabies throughout the world is the dog, but any mammal can be. In some places, cats are carriers more frequently than dogs.
Wild animals can also be carriers of the rabies virus and, as such, can transmit it to domestic animals or to humans. Bats, raccoons, skunks and foxes are common carriers of rabies virus.
It is known that the rabies virus does not last much beyond a body alive. It has been reported that can remain active on carcasses of animals up to 24 hours but not more.
Symptoms and diagnosis of canine rabies
The rabies virus has different incubation times in different species and produces three phases of symptoms characteristic, although not always show all phases. While all mammals are susceptible to rabies, we know that skunks can be asymptomatic carriers in some cases.
Symptoms of rabies in dogs usually appear between three and eight weeks after infection. However, cases have been reported incubation longer, up to six months.
In humans, symptoms usually appear between three and six weeks after infection, but also have been reported cases of incubation longer.
The phases characteristics of rabies are:
 Prodromal phase. It is characterized by behaviors aprehensible, nervous, anxious and voluntary isolation of the dog. It also produces fever. The conduct tends to change during this phase, making dog-friendly form of acting suspicious, timid or irritable. The aggressive dogs can become docile and friendly. This phase usually lasts two to three days in the dog.
 Phase furious. It does not always show, but when it does feature is the phase of what is known as "furious anger". It is characterized by irritability of the animal and hypersensitivity to visual and auditory stimuli. At this stage, the dog does not rest often and seems to be active long time. Dogs bite everything that puts them on the road and with the progress of the disease, showing disoriented and end up having convulsions. Eventually die. This phase normally lasts between one and seven days in dogs.
 Phase paralytic. This phase is characteristic of what is known as "dumb rabies" or "paralytic rabies" and neither is presented in all cases. May occur after the phase or Phase prodrómica furious. Its symptoms include paralysis of the muscles of the head and neck. Thus, the dog can no longer swallow and saliva constantly. The lower jaw was paralyzed leaving his mouth open, the landlord may give the impression that your dog has something stuck in my throat. Eventually, the paralysis affects the diaphragm and the dog died of respiratory failure.
The diagnosis of rabies is based on an analysis of nerve tissue of the brain, making it necessary to kill the dog to diagnose whether it has rabies or not.
There have also been tried other techniques to diagnose rabies in early states, without killing the animal. Among these techniques is the polymerase chain reaction (PCR by its acronym in English), but for the moment the precise diagnosis involves the death of the dog to analyze your brain.
Prevention and treatment of canine rabies
There is no treatment for rabies once symptoms have been submitted. In these cases, the affected individual is sentenced to death.
However, there are e
