Viral infection psittacidae

The sudden death of pups without obvious causes or failure in the plumage, it may be symptoms of some serious viral diseases parrot. Above is a PBFD infection (Psittacine beak and feather disease), Pachecovu disease or polyomavirovou infection.

PBFD is the most common infections, which has been kept at home psittacidae, and therefore the most important. Originator of the disease is small circovirus, which is very durable in the external environment and can survive several years.

Papousek may be infected via inhalation or pozrenim virus, which is a sick bird excreted mainly affected by dust from feathers, faeces, or possibly feces of man. You can also transfer the vertical, ie. that infection occurs in the offspring of females. Man I can work easily as vector of disease, because the dust particles with virus recorded in his clothes. The introduction of infection into farming can serve well as contaminated feed or water.For this reason it is very important to adhere to preventive measures such as proper disinfection cage (suitable disinfectant against the virus is PBFD glutaraldehyde) and compliance with the quarantine and testing of newly arrived psittacidae.

The disease can occur in any type of parrot, though more frequent occurrence is recorded for the species as a cockatoo, eklektus, budgie, Lori, or parrot Agapornis rooted. The infected birds are susceptible under 3 years old and young, which have less developed immune system. The clinical picture of disease is different in age sick bird. The problem is the disease that usually ends fatally. There are three forms of disease - peracutely, acute and chronic. Peracutely course of disease observed in hatched chicks,the owners reported increased mortality without vysvetlitelnych causes. The death occurs without prior symptoms, only in some individuals may arise difficulty breathing, or diarrhea. In the autopsy of dead birds are not any visible changes to the internal organs. The acute form affects birds in the period since the start of operations up to several weeks after leaving the booth. Sick individuals are apaticti and suffering from diarrhea. The cause of diarrhea is the growth of virus in the epithelial cells of the esophagus, crop and intestine. Another goal of the virus in the body cells are the immune system in Fabriciove burs and thyme, but also cells perovych follicles or bone marrow. As a result of damage to the immune system of the birds have a reduced immunity and more frequently they occur secondary infectionmostly in the form of pneumonia. Challenge perovych follicles manifested poor growth of feathers. Feathers are deformed and may show a change in color (for pupils appear red contour feathers). Chronic form of disease is typical of older birds. In the case of sick birds, the feathers fall out and its deformation (newly accrued feathers are curly, often forming hair cysts, which are covered by bloody crust), the problems are increasing with every preperovanim. The first sign of kakaduu or pupil is a shiny black beak due to a malfunctioning peroveho making dust. Disorders of the plumage are symmetrical and usually begin with the tail. Therefore, sometimes the owners come Milne suspected that the bird pen yanks himself.In later stages of the disease changes the horn beak and claws, are fragile and may be in the deeper layers nekrotizovat. As a result of weakening of the immune system associated with secondary bacterial or fungal infections. And this form of disease forecasting has good prospects.
