In the Penza region, the results of studies of 20 samples for infectious avian laryngotracheitis were obtained

For 5 months of 2022, specialists of the Department of State Veterinary Supervision for the Penza Region of the Office of the ROSSELKHOZNADZOR for the Republic of Mordovia and the Penza Region, as part of epizootological monitoring, sent 20 samples for infectious avian laryngotracheitis to the Saratov MVL to study.
Of the 20 samples, 3 positive samples were identified with a low level of post-vaccination antibodies, which indicates a low percentage of post-vaccination immunity. The Department of Rosselkhoznadzor informed the enterprise about the identification of positive samples for taking the necessary measures.
Management reminds that infectious laryngotracheitis is a viral disease. Chickens, peacocks, pheasants and some types of ornamental birds are susceptible to the disease, more often manifested in young chickens aged 60 to 100 days. The virus can also infect humans. This happens to people who have been working with vaccine material for a long time or are forced to come into contact with highly aggressive strains (workers in biofactories and laboratories). With poultry products - MEAT, eggs, feathers - a person cannot become infected. In chickens, the disease is transmitted "from beak to beak", the incubation period is short and is 1-3 days. More often, infectious laryngotracheitis manifests itself in the autumn and spring, when temperature fluctuations weaken the respiratory tract of chickens and general immunity. Factors contributing to infection
Symptoms of the disease are always associated with damage to the respiratory tract: wheezing, coughing, wheezing; discharge from the eyes and nose; when squeezing the trachea with fingers, a cough occurs; when examining the larynx, redness, swelling, pinpoint hemorrhages, accumulation of mucous or curdled masses in the lumen of the larynx are visible. Chickens are oppressed, eat poorly, cyanosis of the comb and earrings is noted. Vaccination during an outbreak of ILT is useless, the introduction of an additional dose of the virus only aggravates the situation. The treatment itself is impractical, an economically justified way out of the situation would be the slaughter of the entire herd, disinfection and the importation of new livestock. If this is not possible, then they resort to methods of partial recovery: a clearly sick and emaciated bird is culled, the rest is treated. Usually the bird gets sick within 14-18 days.
A letter was sent to the Ministry of Agriculture of the Penza region to take the necessary measures.
