Abstract:
Avian infectious bronchitis is one of the most common viral infections causing enormous economic losses in the global poultry industry. Due to the lack of mechanisms to correct errors during genome replication, the virus can quickly mutate and generate new strains. This is facilitated by widespread use of live vaccines, simultaneous circulation of field viruses belonging to different serotypes in one flock and rapid spread of the virus. Previous studies of avian infectious bronchitis virus strains and isolates identified in the Russian Federation poultry farms showed that 50% of samples tested positive for the 4-91, D274, H-120, Ma5 vaccine strains, and the other half of samples tested positive for the field viruses belonging to eight GI genetic lineages, while the G1-19 (QX) lineage was dominant. The paper presents identification and genotyping results of the avian infectious bronchitis virus in one of the poultry farms in the Saratov Oblast (the Russian Federation) in 2018–2019. The samples of internal organs and blood, as well as oropharyngeal and cloacal swabs were taken from chicks and layers of different ages in the parent and replacement flocks. The vaccine strain, GI-19 field isolates and variant isolates that do not belong to any of the known genetic lineages were detected. Analysis of test results within a two-year period showed that it is important to study samples taken from birds of different ages. The virus undergoes modification and adaptation inducing new genetic forms by infecting several poultry generations, due to which the heterogeneity of the virus population is ob­served not only in the poultry farm as a whole or in a separate department, but also within one organism. The identified isolates showed tropism for the tissues of intestine, reproductive organs, and, in rare cases, trachea and lungs. The data obtained indicate that, despite the vaccination used, a genetically diverse population of the infectious bronchitis virus circulates in the poultry farm, while the infection may not manifest itself at an early age, but may affect the flock productivity in the future due to pathological changes in the reproductive organs of laying chickens.

Abstract:
The epidemiological situation regarding the infectious bronchitis virus (IBV) population in Europe as well as the presence of predominant IBV strains is well described. The aim of this epidemiological study was to describe the real field situation in the Czech Republic and Slovakia, as no data are available for the last ten years. The study was also focused on differentiation between field IBV strains and vaccine/vaccine origin IBV strains in different poultry segments including backyard flocks. Between July 2013 and July 2016, cloacal, tracheal and/or visceral swab samples were collected from 145 Czech and Slovak chicken broiler, breeder and layer flocks. The majority of flocks was kept for production purposes, but to enable a more complete picture of the situation in the field backyard flocks with more than 50 birds were also included. As in other cases which were reported worldwide and based on collaboration with x-Ovo laboratories, samples were analysed using the real-time polymerase chain reaction (RT-qPCR) to detect the presence of the RNA of IBV. When positive, approximately 400 base pairs encoding the hypervariable region of the IBV S1 protein were sequenced. Sequencing results, cycle threshold values and vaccination history were used as criteria to try and distinguish vaccine strains from field strains. A significant percentage of all flocks presented clinical signs suggestive of IBV infection. From the total number of samples examined, 16.5% were negative. In 12.4% of the samples that did contain RNA from IBV, the genotype could not be determined. In most cases, this was due to the recovery of RNA quantities below the lower limit of detection of the sequencing PCR. The remaining positive samples predominantly contained RNA from IBV strains that belonged to the 4/91 – 793B – CR88 (44.7%), Massachusetts (30%), D274 – D207 (11.6%) and D388 – QX (8.7%) genotypes. Estimations indicated that approximately 23.9%, 48.4%, 58.3% and 0% of these detections, respectively, were vaccine strains. Infections with types UKR/27/2011, CK/CH/Guandong/Xindadi/0903 and K33/09 were observed sporadically. The results confirm that IBV infections are highly prevalent in Czech and Slovak chickens and that at least seven different IBV types were circulating during the monitored period. This underlines the necessity of providing flocks with a strong and broad protective immunity against IBV.

Abstract:
SUMMARYThe ability of three avian viruses to elicit antibody response in humans was surveyed for the purpose of identifying zoonotic diseases. Antibody levels in people associated with poultry were compared to those in people having limited poultry association. Antibody levels to three avian viruses: infectious bursal disease virus, a birnavirus; Newcastle disease virus, a paramyxovirus; and avian infectious bronchitis virus, a coronavirus were determined by enzyme–linked immunosorbent assays (ELISA). Differences between the two study groups were evident: people having a known association with poultry showed significantly higher levels of antibodies to Newcastle disease and avian infectious bronchitis virus. Antibodies detected may be due to virus exposure rather than zoonoses.

Abstract:
Avian infectious bronchitis (IB) is a highly contagious disease of poultry with high economic importance. Caused by avian infectious bronchitis virus (IBV), it is transmitted by direct and indirect contact through aerosol or fecal means. Although IB is considered as respiratory disease, various strains of IBV affect the renal as well as the reproductive system. The economic importance of disease is due to lower egg production, poor hatchability of eggs, and decreased quality of the egg, weight loss, growth retardation, and high condemnation rates in meat-type birds. Although the prevalence of IB is lower in Nepal (>1%), it is ranked second as a disease which claims most livestock unit in the world. There is no specific treatment for IB but live and inactivated vaccines are available for the prevention and control of the virus. The lack of research in the infectious bronchitis virus can cause production losses in poultry sector due to the evolution of resistant virus strain in our country. This review discusses the aspects of avian infectious bronchitis prevalence in Nepal.

Abstract:
In this study, we demonstrate the synthesis of carbonized nanogels (CNGs) from an amino acid (lysine hydrochloride) using a simple pyrolysis method, resulting in effective viral inhibition properties against infectious bronchitis virus (IBV). The viral inhibition of CNGs was studied using both in vitro (bovine ephemeral fever virus (BEFV) and pseudorabies virus (PRV)) and in ovo (IBV) models, which indicated that the CNGs were able to prevent virus attachment on the cell membrane and penetration into the cell. A very low concentration of 30 μg mL−1 was found to be effective (>98% inhibition) in IBV-infected chicken embryos. The hatching rate and pathology of IBV-infected chicken embryos were greatly improved in the presence of CNGs. CNGs with distinctive virus-neutralizing activities show great potential as a virostatic agent to prevent the spread of avian viruses and to alleviate the pathology of infected avian species.

Abstract:
AbstractThe poultry industry faces challenge amidst global food security crisis. Infectious bronchitis is one of the most important viral infections that cause huge economic loss to the poultry industry worldwide. The causative agent, infectious bronchitis virus (IBV) is an RNA virus with great ability for mutation and recombination; thus, capable of generating new virus strains that are difficult to control. There are many IBV strains found worldwide, including the Massachusetts, 4/91, D274, and QX-like strains that can be grouped under the classic or variant serotypes. Currently, information on the epidemiology, strain diversity, and global distribution of IBV has not been comprehensively reported. This review is an update of current knowledge on the distribution, genetic relationship, and diversity of the IBV strains found worldwide.

Abstract:
Infectious bronchitis (IB) is one of the major economically important poultry diseases distributed worldwide. It is caused by infectious bronchitis virus (IBV) and affects both galliform and nongalliform birds. Its economic impact includes decreased egg production and poor egg quality in layers, stunted growth, poor carcass weight, and mortality in broiler chickens. Although primarily affecting the respiratory tract, IBV demonstrates a wide range of tissues tropism, including the renal and reproductive systems. Thus, disease outcome may be influenced by the organ or tissue involved as well as pathotypes or strain of the infecting virus. Knowledge on the epidemiology of the prevalent IBV strains in a particular region is therefore important to guide control and preventions. Meanwhile previous diagnostic methods such as serology and virus isolations are less sensitive and time consuming, respectively; current methods, such as reverse transcription polymerase chain reaction (RT-PCR), Restriction Fragment Length Polymorphism (RFLP), and sequencing, offer highly sensitive, rapid, and accurate diagnostic results, thus enabling the genotyping of new viral strains within the shortest possible time. This review discusses aspects on pathogenesis and diagnostic methods for IBV infection.

Abstract:
ABSTRACT Major advances in the study of the molecular biology of RNA viruses have resulted from the ability to generate and manipulate full-length genomic cDNAs of the viral genomes with the subsequent synthesis of infectious RNA for the generation of recombinant viruses. Coronaviruses have the largest RNA virus genomes and, together with genetic instability of some cDNA sequences in Escherichia coli, this has hampered the generation of a reverse-genetics system for this group of viruses. In this report, we describe the assembly of a full-length cDNA from the positive-sense genomic RNA of the avian coronavirus, infectious bronchitis virus (IBV), an important poultry pathogen. The IBV genomic cDNA was assembled immediately downstream of a T7 RNA polymerase promoter by in vitro ligation and cloned directly into the vaccinia virus genome. Infectious IBV RNA was generated in situ after the transfection of restricted recombinant vaccinia virus DNA into primary chick kidney cells previously infected with a recombinant fowlpox virus expressing T7 RNA polymerase. Recombinant IBV, containing two marker mutations, was recovered from the transfected cells. These results describe a reverse-genetics system for studying the molecular biology of IBV and establish a paradigm for generating genetically defined vaccines for IBV.

Abstract:
Avian infectious bronchitis is an acute rapidly spreading viral respira­tory disease of chickens characterized by tracheal rales, coughing and sneezing. In adult laying flocks it causes a drastic drop in egg production — most of which are malformed.The disease was first described in the U.S.A. by Schalk and Hawn (1931) and its viral aetiology was confirmed 5 years later (Beach and Schalm, 1936). It is now report­ed to be world-wide in distribution (Estola, 1966).However, the F.A.O. Animal Health Year Books do not .list AIB as being present in Nigeria. Similarly, a recent compilation of Nigeria Veterinary bibliography (1970-1983) did not include AIB and the disease until a previous report (Komolafe and Erojikwe, 1985) has not been described in Nigeria.In the present communication, a serological evidence based on the detection of AIR virus specific preci­pitating antibody in the sera of sufs­pected cases is reported.

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 continuous emergence of novel infectious bronchitis (IB) variants and failure of vaccination. However, similar clinical signs were shown in different respiratory diseases that are essential to improving the diagnostic assay to detect IBV infections. Various risk factors involved in the failure of IB vaccination, such as various routes of application of vaccination, the interval between vaccinations, and challenge with various possible immunosuppression of birds are reviewed. The review article also highlights and updates factors affecting the diagnosis of IBV disease in the poultry industry with differential diagnosis to find the nature of infections compared with non-IBV diseases. Therefore, it is essential to monitor the common reasons for failed IBV vaccinations with preventive action, and proper diagnostic facilities for identifying the infective stage, leading to earlier control and reduced economic losses from IBV disease.

Abstract:
Infectious bronchitis (IB) is one of the most common highly infectious viral respiratory diseases of poultry having wide geographical distribution. Yet, little is known about the infection in the northwestern states of Nigeria. In this study, a total of 263 pooled cloacal and tracheal swab samples were collected from apparently healthy avian species (duck, dove, geese, guinea fowl, local chicken, ostrich, parrot, pigeon, peacock, and turkey). The samples were from nine live bird markets in three states (Kaduna, Kano and Jigawa) of northwestern, Nigeria collected from September through November 2017. Total RNAs were extracted directly from the swab samples and screened for infectious bronchitis virus (IBV) using real-time reverse transcription-polymerase chain reaction. An overall prevalence of 38.0% (100/263)was recorded. IB was detected in 70 % (7/10) of the avian species with prevalence of 100 % in dove, local chicken 45.9 %, duck 42.3 %, geese 26.6 %, pigeon 23.5 %, turkey 20.0 % and guinea fowl 6.2 %. Conversely, no detection was made from ostrich, parrot, and peacock. Widespread distribution of IBV was observed and evidence of subclinical infection in seven out of ten (70 %) of the avian species sampled. These avian species harbouring IBV may act as reservoirs with an influence on the ecology and epidemiology of the disease. Continuous surveillance and characterization of the different serotypes in avian species are recommended to inform the adoption of suitable vaccination strategy and control measures for the disease in Nigeria.

Abstract:
Avian infectious bronchitis virus (IBV) causes considerable economic losses in the poultry industry worldwide, including Taiwan. IBV is among the most important pathogens in chickens, and it spreads rapidly among flocks. In addition to dozens of known serotypes, new viral variants have emerged due to the viral evolution and antigenic variation in IBVs. Therefore, the development of a sensitive, specific, and easily performed assay is crucial for the rapid detection and surveillance of IBV infections. A rapid and simple immunochromatographic strip (ICS) was developed in this study by employing monoclonal antibodies against spike and nucleocapsid proteins of IBV as the tracer and the capture antibody. The ICS showed high specificity in detecting IBV antigens, including several IBV genotypes and novel variants, as opposed to three other common avian respiratory viruses. The detection limit of the strip reached 104.4 50% embryo-infective dose. Moreover, in the experimental chicken model, the strip test demonstrated consistency in detecting IBV with RT-PCR gene detection. Taken together, this antigen detection strip has the potential to serve as an on-farm rapid test for IBV; therefore, it may facilitate surveillance and control of the disease.
