Description. Smallpox is a mild to severe, slow course of the virus by birds, caused by a pox virus have been identified three common types. The three types of cups are poultry ulcers in mouth virus and the target virus canary ulcers in mouth virus. The types may differ in which malignant they occur, as well as have the ability to infect other birds in addition to the groups mentioned, although many of the types is group-specific. Around sixty bird species ulcers in mouth from twenty different groups have been tested positive of bird smallpox.
The prevalence. Birds cups are observed at many varying ulcers in mouth types of birds worldwide. The virus is most common in temperate (hot and humid) parts of the world and is most often observed in relation to mosquito season cycle. Birds cups have been diagnosed in such diverse types as canaries, parrots, finches, pigeons, singing swans, sparrows, turkeys, eagles, cranes, chickens and others ulcers in mouth .. By far back in history have fowlpox been identified in birds, but still appears on which an extremely deadly virus.
Transmission. A smallpox virus can transmit in many ways. One of the primary sources of infection, the mosquitoes that occupy the infection when it sucks blood from an infected bird who has smallpox virus circulating in the bloodstream, or through discharge ulcers in mouth from a smallpox lesion. When the mosquito sucks blood later in an uninfected bird brings the smallpox virus over to this. Mosquitoes can host and transmit the virus a month or longer after the last has sucked the blood of an infected bird. Experiments have shown that stable flies show the capacity to transmit smallpox virus. For direct ulcers in mouth contact between infected and non-infected birds, the virus can be transferred from the skin flakes, open wounds on cups blener or from the mucosa overlying ulcers in mouth the eyeball. Indirect transmission of smallpox virus can also occur when shooting food, water or when feeding bowls, side sticks, cages or clothing infected with smallpox virus. Pox virus is very resistant to drying out, it can survive for months or years in the dry skin flakes from cups blenerne. Indirect transmission ulcers in mouth can also occur through ulcers in mouth inhalation of dander, feathers, dust or airborne particles infected with smallpox virus.
Signs. Signs observed ulcers in mouth by infection with the smallpox virus, are generally weakness, thinness, breathing, difficulty ulcers in mouth swallowing, vision problems, dirty feathers by anus, exuding ring on the eye, inflammation of the eye and the appearance of the characteristic warty blener on ubefjerede areas, or the formation of diftiritis one membrane in the upper part of the trachea.
Disease. Birds cups appears in two forms, skin (dry) and diftiritis (wet). Skin shape is the most common, it is a cumulative infection of skin lesions in the form of wart-like blener. To begin with, this shows the shape of small cups of white, pink, or yellow warts (blister) on ubefjerede parts of the skin (feet, legs, næbroden, eye ring and the head). These warts or blener, occurring when there is excess pressure in the drainage of fluid from bacteria rich pockets forming under the skin. The skin cuticles pushed thereby from each other, there is a warty knotty outgrowth that gradually grow together. The fluid from ruptured cells solidifies, which occurs scabs, the surface of the warts is rugged and dry and the color changes to dark brown or black. The size and number of warts, will depend on the how hard the bird is attacked and the stage of the disease. ulcers in mouth Other bacteria can penetrate into the wounds occurs as secondary infections, which results in matter filled isolation and degradation of the cellular tissue. It takes from 2 to 4 weeks for a complete healing of the skin to the affected area, provided lesions are not so severe as to prevent the bird from absorbing the food.
Diftiritis shape involves the mouth, throat, neck, trachea and lungs. There arises a yellowish or white, moderately raised, moist, cheese-like inflamed area. A diftiritis membrane occurs, thereby hampered breath as the bird gasps for breath and slowly suffocate.
Diagnosis. Without a clinical trial, you can often make the diagnosis birds cups from the large lesions on the bird's body. A microscopic examination, confirmation of bird infected with bird cups. In the laboratory study will make the diagnosis by isolating the virus. There you can inject the organism in eggs, which it is grown so creating a kind of chain reaction in the body and the virus can be excreted.
Treatment. We have tried various forms of treatment for birds cups, but this treatment can only be a supportive care. Can be treated cups of the lesions and prevent secondary infections in the various bird groups, by removing skin lesions (sårkager, scabs on the knobs), brushing with sodium bicarbonate or Lugol solution, iodine washing, remove diftiritis membrane ulcers in mouth of the mouth and throat and then coat the area of Lugol solution, bathing the eye, 1 - 2% salt solution ulcers in mouth and raising the room temperature. Since there is no effective treatment
