Infectious Bronchitis, Avian Infectious Bronchitis, IB is a highly contagious and severe respiratory disease in chickens caused by the Coronavirus. This virus usually infects chickens although some other birds may be infected.
This disease is characterized by several well-known symptoms such as coughing, sneezing, runny nose, and causes very severe respiratory distress. In general, there is a decrease in egg production and a loss of the quality of the internal eggs and the quality of the outer shell. Some strains of the virus cause severe kidney damage and can be associated with high mortality and large deaths in a short period of time.
How infectious is bronchitis
In general, this infectious disease affects the production of eggs and meat and causes great economic losses in the poultry industry. Infected chickens excrete the virus through respiratory secretions and feces so that the virus can spread through the air and infect more poultry, or by ingesting viruses through contaminated feed and drinking water, or direct contact with contaminated tools and clothing.
So that infected chickens can spread the virus for 20 weeks after infection and the incubation period is 24-48 hours, with the peak in the excretion of the virus from the respiratory system from 3-5 days after infection.
How to prevent infectious bronchitis
In general, the severity of the disease in poultry is affected by several other factors, including the quality of the virus strain, the immune status of the poultry, age, the quality of the poultry, the diet and the state of stress and cold, in addition to that, it is also affected by the presence of other additional infections such as intestinal infection.
And because this disease is rapidly spreading and causes very high mortality rates, large mortality in chickens, and large contamination in barns with viruses, this is why the most important methods for controlling the disease and controlling its spread are to protect other barns from this infection, so the proper disposal of dead chickens or infected chickens is carried out and the pens affected are cleaned of the remnants of dung. And the secretions of sick chickens, the remains of the bodies of dead chickens are disposed of by burning in small incinerators or by backfilling in the correct way to prevent infection.
When is bronchitis infectious
Among the bad methods that have been observed by some barn owners and poultry breeders in the Al-Hira area in the south of the city of Tripoli, Libya, which is collecting and stacking piles of dead chickens infected with the infectious bronchitis virus and burning them in the open, and this method is very bad and cannot eliminate the disease virus Rather, this road contributes to the spread of the virus in the vicinity.
It was also noted that the burning process was not completely completed, as the burning did not reach large parts of those stacks, which on the same day after the fire was extinguished, became food for the loose dogs in the area, which contributed to the increase in pollution and the spread of infection. Also, migratory birds were observed in the area eating from the remains of dead chickens.
