Infectious bronchitis of chickens (IBK) is a highly contagious disease that usually affects the tissues of the respiratory tract, kidneys, stomach and oviduct. The causative agent of the disease is the chicken infectious bronchitis virus, belonging to the Coronaviridae family. The virus is ubiquitous and occurs in almost all countries with developed poultry farming. Ways of transmission of the pathogen are diverse: alimentary, aerogenic, contact and transovarial. The incubation period is quite short (1-3, rarely up to 10 days) and the disease usually covers all susceptible birds in the flock within 5-7 days. Birds of all ages are susceptible, but chickens up to 1 month old are most sensitive, their lethality reaches 25%.
Prevention of IBV, in addition to standard veterinary and sanitary measures, also includes vaccination, the effectiveness of which may decrease due to the antigenic heterogeneity of the causative virus. A large number of serotypes are known, new variant viruses are emerging, and immunity acquired to one serotype often does not provide cross protection against infection by viruses of other serotypes. This makes constant monitoring of circulating IBV isolates relevant for further optimization of the disease prevention scheme.
Over the past 2019-2021, the reference laboratory for viral diseases of birds of the Federal State Budgetary Institution "Federal Center for Animal Health" subordinate to ROSSELKHOZNADZOR has been studying samples of pathological material from different regions of RUSSIA and neighboring countries. The virus was detected in 20% of the total number of samples examined. In positive samples, both field isolates and vaccine strains of IBV were differentiated, often simultaneously with field isolates of two genetic lines: G1-19 (QX) and G1-1 (Mass).
The laboratory annually improves methods for diagnosing the disease and is currently able to reliably identify and differentiate vaccine strains and field isolates of the virus by sequencing in the condition of their cocirculation in the body of a bird.
