A low-endotoxic Salmonella enterica Gallinarum serovar delivers infectious bronchitis virus immunogens via a dual-promoter vector system that drives protective immune responses through MHC class-I and -II activation in chickens. Poult Sci 2024; 103:103844. [PMID: 38795516 PMCID: PMC11153243 DOI: 10.1016/j.psj.2024.103844] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2024] [Revised: 05/08/2024] [Accepted: 05/09/2024] [Indexed: 05/28/2024] Open
Abstract
An effective vaccine strategy is indispensable against infectious bronchitis virus (IBV) and fowl typhoid (FT), both of which threaten the poultry industry. This study demonstrates a vector system, pJHL270, designed to express antigens in prokaryotic and eukaryotic cells. The vector system stimulates immune responses via synchronized antigen presentation to MHC class-I and -II molecules to produce balanced Th1/Th2 responses. The vaccine antigens were crafted by selecting the consensus sequence of the N-terminal domain of the spike protein (S1-NTD) and a conserved immunogenic region of the nucleocapsid protein (N321-406 aa) from IBV strains circulating in South Korea. The vaccine antigen was cloned and transformed into a live-attenuated Salmonella Gallinarum (SG) strain, JOL2854 (∆lon, ∆cpxR, ∆rfaL, ∆pagL, ∆asd). Western blot analysis confirmed concurrent antigen expression in Salmonella and eukaryotic cells. Oral immunization with the SG-based IBV vaccine construct JOL2918 induced IBV antigen and Salmonella-specific humoral and cell-mediated immune responses in chickens. PBMCs collected from immunized chickens revealed that MHC class-I and -II expression had increased 3.3-fold and 2.5-fold, respectively, confirming MHC activation via bilateral antigen expression and presentation. Immunization induced neutralizing antibodies (NAbs) and reduced the viral load by 2-fold and 2.5-fold in the trachea and lungs, respectively. The immunized chickens exhibited multifaceted humoral, mucosal, and cell-mediated responses via parallel MHC class-I and -II activation as proof of a balanced Th1/Th2 immune response. The level of NAbs, viral load, and gross and histological analyses provide clear evidence that the construct provides protection against IBV and FT.

Co-infection of H9N2 subtype avian influenza virus and QX genotype live attenuated infectious bronchitis virus increase the pathogenicity in SPF chickens. Vet Microbiol 2024; 295:110163. [PMID: 38959807 DOI: 10.1016/j.vetmic.2024.110163] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2024] [Revised: 06/17/2024] [Accepted: 06/20/2024] [Indexed: 07/05/2024]
Abstract
Avian influenza virus (AIV) infection and vaccination against live attenuated infectious bronchitis virus (aIBV) are frequent in poultry worldwide. Here, we evaluated the clinical effect of H9N2 subtype AIV and QX genotype aIBV co-infection in specific-pathogen-free (SPF) white leghorn chickens and explored the potential mechanisms underlying the observed effects using by 4D-FastDIA-based proteomics. The results showed that co-infection of H9N2 AIV and QX aIBV increased mortality and suppressed the growth of SPF chickens. In particular, severe lesions in the kidneys and slight respiratory signs similar to the symptoms of virulent QX IBV infection were observed in some co-infected chickens, with no such clinical signs observed in single-infected chickens. The replication of H9N2 AIV was significantly enhanced in both the trachea and kidneys, whereas there was only a slight effect on the replication of the QX aIBV. Proteomics analysis showed that the IL-17 signaling pathway was one of the unique pathways enriched in co-infected chickens compared to single infected-chickens. A series of metabolism and immune response-related pathways linked with co-infection were also significantly enriched. Moreover, co-infection of the two pathogens resulted in the enrichment of the negative regulation of telomerase activity. Collectively, our study supports the synergistic effect of the two pathogens, and pointed out that aIBV vaccines might increased IBV-associated lesions due to pathogenic co-infections. Exacerbation of the pathogenicity and mortality in H9N2 AIV and QX aIBV co-infected chickens possibly occurred because of an increase in H9N2 AIV replication, the regulation of telomerase activity, and the disturbance of cell metabolism and the immune system.

Abstract
Synanthropic bird species in human, poultry or livestock environments can increase the spread of pathogens and antibiotic-resistant bacteria between wild and domestic animals. We present the first telemetry-based spatial networks for a small songbird. We quantified landscape connectivity exerted by spotless starling movements, and aimed to determine if connectivity patterns were related to carriage of potential pathogens. We captured 28 starlings on a partridge farm in 2020 and tested them for Avian influenza virus, West Nile virus WNV, Avian orthoavulavirus 1, Coronavirus, Salmonella spp. and Escherichia coli. We did not detect any viruses or Salmonella, but one individual had antibodies against WNV or cross-reacting Flaviviruses. We found E. coli in 61 % (17 of 28) of starlings, 76 % (13 of 17) of which were resistant to gentamicin, 12 % (2 of 17) to cefotaxime/enrofloxacin and 6 % (1 of 17) were phenotypic extended spectrum beta-lactamase (ESBL) carriers. We GPS-tracked 17 starlings and constructed spatial networks showing how their movements (i.e. links) connect different farms with nearby urban and natural habitats (i.e. nodes with different attributes). Using E. coli carriage as a proxy for acquisition/dispersal of bacteria, we found differences across spatial networks constructed for E. coli positive (n = 7) and E. coli negative (n = 9) starlings. We used Exponential Random Graph Models to reveal significant differences between networks. In particular, an urban roost was more connected to other sites by movements of E. coli positive than by movements of E. coli negative starlings. Furthermore, an open pine forest used mainly for roosting was more connected to other sites by movements of E. coli negative than by movements of E. coli positive starlings. Using E. coli as a proxy for a potential pathogen carried by starlings, we reveal the pathways of spread that starlings could provide between farms, urban and natural habitats.

Abstract
Infectious bronchitis virus (IBV), an avian coronavirus, has caused considerable damage to the poultry industry. In Korea, indigenous KM91-like and newly introduced QX-like lineages belonging to the GI-19 lineage have been prevalent despite constant vaccination. In this study, complete genome sequences of 23 IBV isolates in Korea from 2010 to 2020 were obtained using next-generation sequencing, and their phylogenetic relationship and recombination events were analyzed. Phylogenetic analysis based on the S1 gene showed that all isolates belonged to the GI-19 lineage and were divided into five subgroups (KM91-like, K40/09-like, and QX-like II to IV). Among the 23 isolates, 14 recombinants were found, including frequent recombination between KM91-like and QX-like strains. In addition, it was observed that other lineages, such as GI-1, GI-13, and GI-16, were involved in recombination. Most recombination breakpoints were detected in the ORF1ab gene, particularly nsp3. However, when considering the size of each genome, recombination occurred more frequently in the 3a, E and 5a genes. Taken together, genetic recombination frequently occurred throughout the entire genome between various IBV strains in Korea, including live attenuated vaccine strain. Our study suggests the necessity of further research on the contribution of recombination of genomes outside the spike region to the biological characteristics of IBV.

Abstract
Despite vaccine use, novel strains and variants of infectious bronchitis virus (IBV) have emerged continuously, leading to economic losses to the poultry industry worldwide. This study aimed to characterize the IBV isolate CK/CH/GX/202109 from three yellow broilers in Guangxi, China. Recombination was shown to have occurred in regions of the 1ab gene. Compared to the whole genome of ck/CH/LGX/130530, which is genotypically related to tl/CH/LDT3-03, the 202109 strain had 21 mutations. The pathological assessment showed that this variant caused 30% and 40% mortality in 1-day-old chicks infected with oral and ocular inoculum, respectively. Nephritis, enlarged proventriculus, inflammation of the gizzard, and atrophy of the bursa of Fabricius were also observed at both 7 and 14 days post-infection (dpi). Viral loads in the trachea, proventriculus, gizzard, kidney, bursa, and cloacal swabs were higher at 7 dpi than at 14 dpi. Clinicopathological and immunohistochemical analyses revealed that this virus exhibited multiple organ tropisms capable of infecting the trachea, proventriculus, gizzard, kidney, bursa, ileum, jejunum, and rectum. Almost none of the 1-day-old infected chicks seroconverted until 14 dpi. While the virus was found in the ileum, jejunum, and rectum in the 28-day-old ocular group, the majority of 28-day-old infected chickens seroconverted at 10 dpi. These study findings demonstrate that recombination events and mutations during the evolution of IBV may greatly alter tissue tropism and emphasize the need for the continued surveillance of novel strains and variants in order to control this infection.

Abstract
The recent centennial anniversary of R.E. Montgomery's seminal published description of "a form of swine fever" disease transmitted from wild African pigs to European domestic pigs is a call to action to accelerate African Swine Fever (ASF) vaccine research and development. ASF modified live virus (MLV) first-generation gene deleted vaccine candidates currently offer the most promise to meet international and national guidelines and regulatory requirements for veterinary product licensure and market authorization. A major, rate-limiting impediment to the acceleration of current as well as future vaccine candidates into regulatory development is the absence of internationally harmonized standards for assessing vaccine purity, potency, safety, and efficacy. This review summarizes the asymmetrical landscape of peer-reviewed published literature on ASF MLV vaccine approaches and lead candidates, primarily studied to date in the research laboratory in proof-of-concept or early feasibility clinical safety and efficacy studies. Initial recommendations are offered toward eventual consensus of international harmonized guidelines and standards for ASF MLV vaccine purity, potency, safety, and efficacy. To help ensure the successful regulatory development and approval of ASF MLV first generation vaccines by national regulatory associated government agencies, the World Organisation for Animal Health (WOAH) establishment and publication of harmonized international guidelines is paramount.

Abstract
Live-attenuated SARS-CoV-2 vaccines received relatively little attention during the COVID-19 pandemic. Despite this, several methods of obtaining attenuated coronaviruses are known. In this systematic review, the strategies of coronavirus attenuation, which may potentially be applied to SARS-CoV-2, were identified. PubMed, Scopus, Web of Science and Embase databases were searched to identify relevant articles describing attenuating mutations tested in vivo. In case of coronaviruses other than SARS-CoV-2, sequence alignment was used to exclude attenuating mutations that cannot be applied to SARS-CoV-2. Potential immunogenicity, safety and efficacy of the attenuated SARS-CoV-2 vaccine were discussed based on animal studies data. A total of 27 attenuation strategies, used to create 101 different coronaviruses, have been described in 56 eligible articles. The disruption of the furin cleavage site in the SARS-CoV-2 spike protein was identified as the most promising strategy. The replacement of core sequences of transcriptional regulatory signals, which prevents recombination with wild-type viruses, also appears particularly advantageous. Other important attenuating mutations encompassed mostly the prevention of evasion of innate immunity. Sufficiently attenuated coronaviruses typically caused no meaningful disease in susceptible animals and protected them from challenges with virulent virus. This indicates that attenuated COVID-19 vaccines may be considered as a potential strategy to fight the threat posed by SARS-CoV-2.

Abstract
The high mutation rate of infectious bronchitis virus (IBV) poses a significant threat to the protective efficacy of vaccines. This study aimed at analyzing the S1 genes of IBV field strains isolated in Southwestern China from 2018 to 2020, assessing the pathogenicity of four dominating strains, and evaluating the protective efficacy of four commercial vaccine strains against the endemic representative strains. Thirty-two field strains of IBV were isolated in Southwestern China from 2018 to 2020. Phylogenetic analysis of their S1 genes revealed the nucleotide homology ranged from 64.6% to 100%, and belonged to five genotypes [GI-19 (QX, 53.13%), GI-28 (LDT3-A,15.63%), GI-7 (TW, 12.50%), GI-1 (Mass, 6.23%), GVI-1 (TC07-2, 6.25%)], and two variant groups [variant-3 (3.13%) and variant-5 (3.13%)]. Recombination events between field and vaccine strains or between field strains were identified in the S1 genes of eight IBV field strains. The CK/CH/YNKM/191128 and CK/CH/CQBS/191203 strains of GI-19 showed morbidity rates of 66.7% and 73.7%, respectively, and mortality rates of 13.3% and 33.3%, respectively. Besides, the CK/CH/SCYC/191030 and CK/CH/GZGY/191021 strains of GI-28 caused morbidity rates of 60% and 86.7%, respectively, and mortality rates of 33.3%. The protective efficacy of the four commercial live vaccine strains (4/91, FNO-E55, LDT3-A, and QXL87) ranged from 70% - 100% and reduced tissue lesions against CK/CH/GZGY/191021 and CK/CH/CQBS/191203 strains. LDT3-A strain was the most effective one but still could not completely prohibit IBV shedding. These findings provide a reference for IBV molecular evolution analysis and control of IB.

Sun L, Tang X, Qi J, Zhang C, Zhao J, Zhang G, Zhao Y. Two newly isolated GVI lineage infectious bronchitis viruses in China show unique molecular and pathogenicity characteristics. INFECTION GENETICS AND EVOLUTION 2021; 94:105006. [PMID: 34293479 DOI: 10.1016/j.meegid.2021.105006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/05/2021] [Revised: 06/29/2021] [Accepted: 07/15/2021] [Indexed: 10/20/2022]
Abstract
During 2016 to 2020, GVI-1 type infectious bronchitis virus (IBV) strains were sporadically reported across China, indicating a new epidemic trend of the virus. Here we investigated the molecular characteristics and pathogenicity of two newly isolated GVI-1 type IBV virus strains (CK/CH/TJ1904 and CK/CH/NP2011) from infected chicken farms in China. Genetic evolution analysis of the S1 gene showed the highest homology with the GVI-1 representative strain, TC07-2. Phylogenetic analysis and recombination analysis of the virus genomes indicated that newly isolated strains in China may be independently derived from recombination events that occurred between GI-19 and GI-22 strains and early GVI-1 viruses. Interestingly, unlike the deduced parental GI-19 or GI-22 strains, CK/CH/TJ1904 and CK/CH/NP2011 showed affinity for the trachea rather than the kidney and were less pathogenic. This difference may be because of recombination events that occurred during the long co-existence of the GVI-1 viruses with prevalent GI-19 and GI-22 strains. Considering the new trend, it is very important to permanently monitor circulating strains and to develop new vaccines to counteract emerging new-type IBVs.

Recombination Events Shape the Genomic Evolution of Infectious Bronchitis Virus in Europe. Viruses 2021; 13:v13040535. [PMID: 33804824 PMCID: PMC8063831 DOI: 10.3390/v13040535] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2021] [Revised: 02/10/2021] [Accepted: 02/12/2021] [Indexed: 12/13/2022] Open
Abstract
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 the genome of 20 randomly selected strains from seven European countries. After sequencing, we created a genome sequence data set that contained 36 European origin field isolates and 33 vaccine strains. When analyzing these 69 IBV genome sequences, we identified 215 recombination events highlighting that some strains had multiple recombination breaking points. Recombination hot spots were identified mostly in the regions coding for non-structural proteins, and multiple recombination hot spots were identified in the nsp2, nsp3, nsp8, and nsp12 coding regions. Recombination occurred among different IBV genotypes and involved both field and vaccine IBV strains. Ninety percent of field strains and nearly half of vaccine strains showed evidence of recombination. Despite the low number and the scattered geographical and temporal origin of whole-genome sequence data collected from European Gammacoronaviruses, this study underlines the importance of recombination as a major evolutionary mechanism of IBVs.

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 virus (IBV) of GI-19 (QX), GI-7 (TW), GI-13 (4/91) and GI-1 (Mass) lineages have been frequently detected in China in recent years. Here, An IBV strain, referred as GD17/04, was isolated from the dead yellow feather chicken vaccinated with H52 and 4/91 vaccines, whose genome sequence was obtained through high-throughput sequencing. Then it has been confirmed by the RDP and SimPlot analysis that GD17/04 is a recombinant strain deriving from YX10, 4/91, TW 2575/98 and H52 strains. Therein S1 gene of GD17/04 consists of sequences of TW2575/98 and 4/91, the former for the region of 20,371 to 21,072 nt and 21,847 to 21,975 nt, the latter for the sandwiched region of 21,073 to 21,846 nt. Moreover, as a nephropathogenic variant which caused high morbidity of 100 % and mortality of 60 %, unlike most other IBV strains, GD17/04 can cause obvious cell lesion in primary CEK cell, and even in DF-1 cells, without the process of continuous passage. As the few IBV strain can infect avian passage cell line, GD17/04 provides a material basis for further study of the interaction mechanism between IBV and avian host. Collectively, the findings highlight the significance that biological characteristics of novel strain should be studied, in addition to constant epidemiologic and molecular surveillance for IBV.
