Chicken Infectious Anemia Virus Markedly Enhances the Pathogenicity of Infectious Bronchitis Virus–Infected Chickens

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Chicken infectious anemia virus (CIAV) and infectious bronchitis virus (IBV) represent two of the most economically significant pathogens in the global poultry production. In recent years, coinfections involving CIAV and IBV have become increasingly prevalent in clinical scenarios across Southern China and globally.

The Tetrahydroisoquinoline Derivative SP9 Exhibits Antiviral Activity Against PEDV and MHV

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Coronaviruses exhibit high mutation rates and cross‐species transmissibility, posing a persistent threat to human and animal health and underscoring the urgent need for antivirals that can compensate for the limited crossprotection afforded by current vaccines.

Novel Variation in the N Protein of Avian Infectious Bronchitis Virus

Virology, 1996
The nucleocapsid protein of coronaviruses has been considered highly conserved, showing greater than 94% conservation within strains of a given species. We determined the nucleotide sequence of the N gene and the 3' untranslated region (UTR) of eight naturally occurring strains of IBV which differed in pathogenicity and tissue tropism.

Subcellular location and protein interactions of the infectious bronchitis virus gene 3 and 5 accessory proteins [PDF]

The avian coronavirus infectious bronchitis virus (IBV) expresses four nonstructural, non-gene 1 proteins (3a, 3b, 5a and 5b) which have been shown to be dispensable for virus replication in cell culture.

Vaccine‐Associated Recombination and Virulence Heterogeneity of GI‐19 (QX Type) Infectious Bronchitis Virus in Eastern and Southern China, 2024−2025

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Infectious bronchitis (IB) virus (IBV) remains a major pathogen threatening the poultry industry. Its rapid mutation and recombination continuously generate variants that disseminate worldwide. Between May 2024 and February 2025, 49 field strains were isolated from chickens vaccinated with live‐attenuated IBV vaccines (H120, 4/91, or QXL87) in four ...

Cellular tropism and cell-to-cell fusion properties of the infectious bronchitis virus spike glycoprotein [PDF]

There are numerous vaccines available for the control of infectious bronchitis virus (IBV) in poultry, however protection is short-lived and poorly cross-protective between strains.

Pathogenicity and Bioinformatics Analysis of Two GI‐13 Infectious Bronchitis Virus Strains in China

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Despite long‐term vaccination and control efforts, infectious bronchitis virus (IBV) remains a major threat to the global poultry industry, largely due to its high prevalence and extensive genetic diversity. This study aimed to characterize two novel GI‐13 (4/91‐like) IBV field strains, CK/CH/JS/2302 and CK/CH/AH/2307, isolated from H120‐vaccinated ...

Genetic Diversity of Avian Infectious Bronchitis Virus Isolated from Domestic Chicken Flocks and Coronaviruses from Feral Pigeons in Brazil Between 2003 and 2009

, 2015
To detect the presence of infectious bronchitis virus or avian coronavirus, a nested reverse transcriptase PCR (RT-PCR) method was developed with the aim of amplifying a fragment of 530 bases, comprising the gene coding SI protein. In the first step, all

Characteristics of Avian Coronaviruses in China From 2020 to 2023

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Avian coronaviruses (CoVs) represent a significant threat to the poultry industry. To understand the epidemiological characteristics of avian CoVs in China, a nationwide surveillance was performed across 16 provinces from 2020 to 2023. More than 46,000 oropharyngeal/cloacal swab samples were collected and detected by RT‐PCR using specific primers for ...
