And Control

The poultry industry is one of the most efficient and flourishing sectors of agriculture that not only provides cheaper protein (eggs, meat) but also contributes heavily to the country's economy. There are several challenges faced by the poultry industry worldwide. Among all these challenges, disease management has been a major problem. Infectious bronchitis viruses (IBVs) are RNA-based viruses having high recombination and mutation rates. IBVs are gamma coronaviruses affecting the upper respiratory tract of chickens. Due to the high rate of mutation and recombination, IBVs are very difficult to properly diagnose and control. Some serotype IBVs are extremely resistant, causing high economic losses in the form of excessive use of antibiotics after the eruption of secondary pathogens and mortality, but some serotype IBVs are limited to morbidity losses only. There are some control methods for IBVs and practicing effective vaccination and biosecurity measures is highly recommended. Exposure of IBVs to chicken flock postulates gateway to secondary pathogens, which also pass on to coming generations. This review paper provides updated research tools and methods to diagnose and control IBVs.

Background and Aim: Existing data on the characteristics of infectious bronchitis virus (IBV) gathered throughout Indonesia have been recognized to indicate variants similar to globally distributed vaccine strains. Despite past and current intensive vaccination programs, IBV infections in the country's poultry industry have not been effectively controlled. Therefore, this study aimed to investigate the genotype of several isolates based on partial S1 gene sequences. In particular, the investigation is directed to focus on layer chickens in actively vaccinated farms indicating IBV symptoms. Materials and Methods: Samples were isolated from ten different layer chicken flocks experiencing respiratory problem, drops in egg production, and a "penguin-like" stance, which were collected from commercial poultry farms in Central Java and Yogyakarta regions, Indonesia, within the periods of 2012-2018. Fragment of the S1 gene of IBV sampled from actively vaccinated commercial poultry farms was amplified using primer 5'-aca tgg taa ttt ttc aga tgg-3' (forward) and 5'-cag att gct tac aac cac c-3' (reverse) with the length of polymerase chain reaction (PCR) product at 383 bp. The sequence of samples was then compared with the sequence of reference S1 gene nucleotides of IBV from NCBI GenBank database. The amino acid analysis and multiple alignment sequence were conducted using Mega X. Results: During necropsy, enlargement of the oviduct and swollen kidney were observed. Reverse transcription-PCR diagnosis of their 383 bp S1 gene showed that all samples were IBV positive. Phylogenetic analysis of the S1 gene discovered seven samples to be clustered as 4/91-like strains. Meanwhile, the remaining three samples were grouped in QX-like strain cluster. Conclusion: This study is a pioneering report providing molecular evidence of pathogenic QX-like and 4/91-like strains circulating in Indonesia. Findings discovered, in this study, strongly suggested the importance of improving protections by available IBV vaccines through updated circulating strain clusters. It is critical to ensure the delivery of an effective control measurement of and vaccination protocols against IBV infections in the country's commercial poultry industry in particular and worldwide in general.
