Is a highly infectious disease that affects young geese. Is susceptible to all races of domestic geese. Other breeds of domestic poultry and ducks seem to be resistant to infection.
The course of disease, geese vertically (and horizontally spread the egg of the stud from the channel (direct contact with infected feces or through indirect contact with an infected an incident of environmental contamination that is caused by goose. Secrete large amounts of virus in feces of infected geese, directly and indirectly intact quickly and this can lead to infection. A major way of transmission is vertical transmission. Subclinical infected as old geese, eggs acts as carriers of disease and viruses transmit to their offspring.
During the acute phase of the disease, infected animals secrete large amounts of virus into the environment with feces, spreading the infection quickly and this version. Healthy rescued animals at a later age or those that are infected become carriers. Due to resistance in the environment, parvovirus, cleaned and disinfected buildings and you can continue on bad surfaces, this causes to get involved in the next version. And egg shell contamination or infection, vertical transmission, disease-plays an important role in sticking to the free version.Outbreaks of the virus after transmission through infected eggs yumurtlanan by breeder geese, seen in the offspring begins. Survivors of the disease and initially infected geese, can become persistent carriers of the virus when they are 4 weeks.
Parvovirus outbreaks in countries that are not never before seen, the cause of the epidemic infected eggs are. These eggs, incipient outbreaks of the virus in the source.
Why else would the duck is closely related to parvo virus, goose parvovirus does not imply similarity of bird or other mammal, think. After the primary infection, the virus to grow and more in a short time after the wall of the intestine, heart, liver and reaches other organs.
Depends on the age and immunological status of the birds of disease progression and symptoms.
Infected in hatcheries in the crash death rate may reach 100%. Older in crash of the disease, ocular and nasal discharge, diarrhea with white in abundance, and is characterized by weakness follows a longer cruise. The geese who survived the acute phase, especially in the back, hair loss and reddening of the skin, together with exhibit growth retardation.Acidic due to the accumulation of fluid in the snow “penguin-like” posture they show..
There is no specific treatment for goose parvovirus infection. Antibiotics are only used to reduce secondary bacterial or fungal infection arising from the losses have been.
Goose think many of the outbreaks, disease transmission during out of eggs due to eggs that are collected from different flocks kuluckalanma is not recommended. Only known parvovirus-free eggs from flocks should be used. Hatchery hygiene must be maintained.
Natural ways that have been vaccinated geese and Muscovy ducks infected or fertile, egg yolks maternal transfer of antibodies through generations. This passively acquired antibody, antibodies depending on the level of individual pups daily, in two to four weeks may continue. Since the disease is limited to young geese and Muscovy ducks, control measures aim to provide adequate immunity during the first six to eight weeks of life.
Rebel two main categories can be distinguished: live and inactivated vaccines.
Live vaccines , attenuated goose parvovirus in animals without maternal antibody that can induce rapid immune responses and protection includes.Even at a very low level of Maternal antibodies, the vaccine can prevent the immune response to neutralize and thus live warn.
Vaccines are inactivated (“killed”), or monovalent (think goose), or bivalent (both goose and Muscovy duck think) form contains all of parvovirus antigens.
The advantage of live attenuated vaccines are sensitive to a rapid immune crash is beginning, however, with live vaccines inducing immune, vaccination, maternal antibodies in the circulation depends on the presence of during think. At an early age when a Live vaccine is used, the presence of passively acquired antibodies in the active immune response that intervened in the development of a regular observation. On the other hand, a high antigen content inactivated vaccines, maternal antibodies, passive immunity and induce protection in the face of. The disadvantage is relatively slow immune response of the inactivated vaccine.
INOCULATION IS PERFORMED IN THE FOLLOWING WAYS
1 – newly hatched birds or passive immunisation with serum the healing of my sperm
2 – Adult breeding geese and Muscovy ducks that have been vaccinated with live vaccines and inactive, and
3-the vaccine has been Attenuated both adults and young animals that have been inactive for alone or combination be used in conjunction with active immunization. Attenuated vaccines can provide good protection in young animals, but only maternal antibodies derived think you are as non-or at very low levels when it’s given to the excavation.
The vaccination strategy most appropriate in all life shall be protected against the cubs and the ducks early and late forms of the disease. Maternal antibodies are protective for non-protection after the fall of the level to extend the inoculation of ducklings and geese before reaching the age of seven to 10 days, is required to stimulate active immunity in the face of ongoing maternal antibodies. In order to obtain stronger and more durable immune response, a booster vaccination (approximately two to three weeks) is also suggested.These are just the high that has been inactive antigen-containing vaccines can be done with the use of.
