... Avian infectious bronchitis is one of the most important respiratory diseases affecting poultry production worldwide. The etiological agent of this disease is the avian infectious bronchitis virus (IBV). We analyzed 14 isolates of IBV obtained from poultry farms in Costa Rica, from 2016 through 2019. We sequenced the S1 region of the genome and the sequences obtained were submitted to GenBank. Phy ...

Abstract:
... Infectious bronchitis virus (IBV) causes avian infectious bronchitis (IB) and there are multiple serotypes worldwide originating from deletions, insertions, point mutations, and RNA recombination. In this study, a recombinant IBV, named CK/CH/MY/2020, was isolated from southwest China. Sequencing and phylogenetic analysis revealed that CK/CH/MY/2020 consists of 27,614 nucleotides and belongs to th ...

Abstract:
... Avian influenza virus (AIV) variants emerge frequently, which challenges rapid diagnosis. Appropriate diagnosis reaching the sub- and pathotype level is the basis of combatting notifiable AIV infections. Real-time RT-PCR (RT-qPCR) has become a standard diagnostic tool. Here, a total of 24 arrayed RT-qPCRs is introduced for full subtyping of 16 hemagglutinin and nine neuraminidase subtypes of AIV. ...
... Infectious bronchitis (IB) causes significant economic losses in the global poultry industry. Control of IB is hindered by the genetic diversity of the causative agent, infectious bronchitis virus (IBV), which has led to the emergence of several serotypes that lack complete serologic cross-protection. Although serotyping requires immunologic characterization, genotyping is an efficient means to id ...

Abstract:
... Alpha-monolaurin has been demonstrated to have antipathogenic properties and is therefore used as feed additive for broilers to prevent infectious diseases and improve production performance. As its antiviral effect is thought to be exerted by disintegrating the viral envelope, α-monolaurin might counteract with the current vaccination programs used in poultry production that are based on administ ...

The virucidal activities were evaluated by spraying slightly acidic hypochlorous acid waters (SAHWs) containing various concentrations of free available chlorine - 100, 200, 300 and 500 ppm (SAHW-100, -200, -300 and -500, respectively) - toward aerosol of an avian coronavirus (infectious bronchitis virus: IBV). The viral solution was supplemented with 0.5% fetal bovine serum (FBS) to simulate norm ...
... Infectious bronchitis (IB) is a highly contagious respiratory disease caused by a gammacoronavirus that has been circulating for many years in chickens in Bangladesh, resulting in significant economic losses. The aim of this study was to detect and characterize infectious bronchitis virus (IBV) from clinical outbreaks and surveillance samples. Real-time RT-PCR was used to detect IBV in pooled lung ...

... Infectious bronchitis of chicken is a high morbidity and mortality viral disease affecting the poultry industry worldwide; therefore, a better understanding of this pathogen is of utmost importance. The primary aim of this study was to obtain a deeper insight into the genomic diversity of field infectious bronchitis virus (IBV) strains using phylogenetic and recombination analysis. We sequenced th ...
... Avian infectious bronchitis (IB) was caused by infectious bronchitis virus (IBV), a coronavirus, which leads to enormous economic losses in the poultry industry. Studies have shown that lithium chloride (LiCl) is a good virus inhibitor. Through cell culture, virus infection, and RT-qPCR, we found that LiCl could down-regulate the apoptosis-related genes Caspase-3 and Bax, up-regulate Bcl-2, and do ...

This virus caused an outbreak with great economic impact to the local poultry industry. The genome sequence is 27 696 bp in length, with the following genome organization 5′-UTR-Pol-S-3a-3b-E-4b-4c-M-5a-5b-N-6b-3 ...

Abstract:
... Infectious bronchitis virus (IBV) is a major economic problem in commercial chicken farms with acute multiple-system infection, especially in respiratory and urogenital systems. A live-attenuated and killed vaccine is currently immunized to control IBV infection; however, repeated outbreaks occur in both unvaccinated and vaccinated birds due to the choice of inadequate vaccine candidates and conti ...

... Infectious bronchitis (IB) continues to be a global threat to poultry producers. The chicken major histocompatibility complex (MHC) or chicken B complex is compact, restricted to a single chromosome, and approximately 20-fold smaller than the mammalian MHC. Abundant evidence indicates that the B complex is strongly associated with resistance to various infectious agents in chickens. While an assoc ...

Abstract:
... Infectious bronchitis virus (IBV), a gammacoronavirus, is an economically important virus to the poultry industry, as well as a significant welfare issue for chickens. As for all positive strand RNA viruses, IBV infection causes rearrangements of the host cell intracellular membranes to form replication organelles. Replication organelle formation is a highly conserved and vital step in the viral l ...
... Fowl adenovirus (FAdV) infections in chickens have resulted in global economic losses in the poultry industry. Infectious bursal disease virus (IBDV) and chicken anemia virus (CAV) infections lead to immunosuppression in chickens, and concomitant co- infection with FAdV usually produces severe and lethal infections. These co-infections are common occurrences on chicken farms and affect large numbe ...
