Article Synopsis
- * Infectious bronchitis virus was the most frequently detected, found in 110 farms, while Newcastle disease virus and avian influenza H9N2 were detected in fewer farms, indicating respiratory issues in broilers are primarily linked to infectious bronchitis.
- * The study emphasizes the need for ongoing monitoring and annual reviews of vaccination plans to effectively control respiratory syndromes and address the changing dynamics of viral infections in poultry farms.
The nephropathogenic infectious bronchitis virus (IBV) strain IS-1494 like (variant-2; GI-23) was first isolated in the Middle East (1998). Despite intensive vaccinations, IS-1494 like IBVs are still circulating in Iran (the dominant genotype) and spread to other countries. Here, the full-length genome of this Iranian IS-1494 like IBV was (Mahed) determined to understand its evolutionary relationships.

- * In 2014, 67.5% of sampled farms and 48.9% of birds tested positive for H9N2, while in 2015, 59.4% of farms and 35.9% of birds were positive, indicating a decline in seropositivity.
- * The findings highlight the need for stronger veterinary biosecurity measures on farms to address the ongoing threat of H9N2, as more poultry operations continue to emerge in the region.
