Background:
Infectious diseases of young and adult birds with respiratory syndrome are a significant deterrent to the development of industrial poultry farming due to a decrease in productivity and significant mortality. The only effective method of combating viral diseases is timely and targeted vaccination, which largely depends on laboratory diagnostic results.
Aim:
The aim of this article is to study the real-time reverse transcription polymerase chain reaction, which has the prospect of more effective diagnosis of vaccine strains of chicken infectious bronchitis and Newcastle disease.
Methods:
The fastest and most accurate method for the differential diagnosis of pathogens in an associative viral infection is reverse transcription polymerase chain reaction. The method proposed in the article for selecting primers for amplification made it possible to use this method for the simultaneous interspecies differential diagnosis of two or more viral agents, which significantly accelerated their diagnosis.
Results:
The correlation of the nucleotide sequence obtained as a result of sequencing to a specific strain of the virus is complicated by the lack of a single nomenclature mechanism for separating genetic groups.
Conclusion:
The results of this study will allow easy and fast typing of sequences into known and databased virus strains, and avoid further confusion in the nomenclature of genetic groups in the future.
