Abstract
The potentially fatal COVID-19 pandemic has been associated with a largespectrum of clinical presentations. Beyond the classical pulmonary manifestations, gastrointestinal tract-related symptoms suchas nausea, diarrhea, abdominal distention and pain have been observed in patients, as a consequence of the binding of SARS-CoV-19 to Angiotensin-converting Enzyme 2 (ACE2) receptors in the gastrointestinal (GI) tract. The early recognition ofspecific imaging features, including hepatobiliary involvement, pancreatic involvement, development of solid organ infarcts, ischemic bowel changes and vascular occlusion, plays a key role through the course of the disease. Also, suspicious symptoms, especially in critically ill patients with clinical and biochemical markers of hypovolemia, necessitate timely imaging for bleeding complications. The aim of this pictorial review is to illustrate the spectrum of the GIimaging findings in patients with COVID-19. Awareness of diagnostic imaging hallmarks is crucial to optimize the management of these patients.

Abstract
Involvement of gastrointestinal tract has been reported in individuals diagnosed with COVID-19. Herein, we report a case of 65-year-old woman with type 2 diabetes mellitus, hypertension, and end-stage renal disease undergoing hemodialysis who was initially diagnosed with COVID-19 on a screening test. During the course of the disease, her respiratory symptoms remained mild; however, she developed acute pancreatitis leading to severe hypertension and hyperosmolar hyperglycemic state. During the hospitalization and treatment of acute pancreatitis, hyperglycemia, and hypertension, her condition improved and she was discharged in stable condition.

Occurrence and Phylogenetic Analysis of Avian Coronaviruses in Domestic Pigeons (Columba livia domestica) in Poland between 2016 and 2020. Pathogens 2022; 11:pathogens11060646.

Abstract
While disease control in racing pigeons and the potential role of pigeons as vectors transmitting viruses to poultry are of importance, there is still a paucity of data concerning the occurrence of coronaviruses in pigeons. In this study, 215 domestic pigeons were tested for the presence of coronaviral genetic material using the nested PCR method, which revealed 57 positive samples (26.51%). The difference in coronavirus prevalence between young and adult pigeons (34.34% and 19.83%, respectively) has been found statistically significant. In contrast, no statistically significant difference has been demonstrated between the prevalence in symptomatic and asymptomatic birds, leaving the influence of coronavirus presence on pigeon health uncertain. Phylogenetic analysis of the RdRp gene fragment allowed us to assign all the obtained strains to the Gammacoronavirus genus and Igacovirus subgenus. The phylogenetic tree plotted using the ML method revealed that those sequences formed a group most similar to pigeon coronavirus strains from China, Finland, and Poland, and to a single strain from a common starling from Poland, which suggests wide geographical distribution of the virus and its possible transmission between various species.

Abstract
Spike (S) glycoprotein is an important virulent factor for coronaviruses (CoVs), and variants of CoVs have been characterized based on S gene analysis. We present phylogenetic relationship of an isolated infectious bronchitis virus (IBV) strain with reference to the available genome and protein sequences based on network, multiple sequence, selection pressure, and evolutionary fingerprinting analysis in People's Republic of China. One hundred and elven strains of CoVs i.e., Alphacoronaviruses (Alpha-CoVs; n = 12), Betacoronaviruses (Beta-CoVs; n = 37), Gammacoronaviruses (Gamma-CoVs; n = 46), and Deltacoronaviruses (Delta-CoVs; n = 16) were selected for this purpose. Phylogenetically, SARS-CoV-2 and SARS-CoVs clustered together with Bat-CoVs and MERS-CoV of Beta-CoVs (C). The IBV HH06 of Avian-CoVs was closely related to Duck-CoV and partridge S14, LDT3 (teal and chicken host). Beluga whale-CoV (SW1) and Bottlenose dolphin-CoVs of mammalian origin branched distantly from other animal origin viruses, however, making group with Avian-CoVs altogether into Gamma-CoVs. The motif analysis indicated well-conserved domains on S protein, which were similar within the same phylogenetic class and but variable at different domains of different origins. Recombination network tree indicated SARS-CoV-2, SARS-CoV, and Bat-CoVs, although branched differently, shared common clades. The MERS-CoVs of camel and human origin spread branched into a different clade, however, was closely associated closely with SARS-CoV-2, SARS-CoV, and Bat-CoVs. Whereas, HCoV-OC43 has human origin and branched together with bovine CoVs with but significant distant from other CoVs like SARS CoV-2 and SARS-CoV of human origin. These findings explain that CoVs' constant genetic recombination and evolutionary process that might maintain them as a potential veterinary and human epidemic threat.

Abstract
Coronaviruses (CoVs) are worldwide distributed RNA-viruses affecting several species, including humans, and causing a broad spectrum of diseases. Historically, they have not been considered a severe threat to public health until two outbreaks of COVs-related atypical human pneumonia derived from animal hosts appeared in 2002 and in 2012. The concern related to CoVs infection dramatically rose after the COVID-19 global outbreak, for which a spill-over from wild animals is also most likely. In light of this CoV zoonotic risk, and their ability to adapt to new species and dramatically spread, it appears pivotal to understand the pathophysiology and mechanisms of tissue injury of known CoVs within the "One-Health" concept. This review specifically describes all CoVs diseases in animals, schematically representing the tissue damage and summarizing the major lesions in an attempt to compare and put them in relation, also with human infections. Some information on pathogenesis and genetic diversity is also included. Investigating the lesions and distribution of CoVs can be crucial to understand and monitor the evolution of these viruses as well as of other pathogens and to further deepen the pathogenesis and transmission of this disease to help public health preventive measures and therapies.

Abstract
The diseases with watery droppings (diarrhea and/or polyuria) can be considered some of the most severe health problems in domestic pigeons of various ages. Although they do not always lead to bird death, they can contribute to poor weight gains and hindered development of young pigeons and, potentially, to poor racing results in sports birds. The gastrointestinal tract disorders of pigeons may be of various etiology, but some of the causative agents are viral infections. This review article provides information collected from scientific reports on RNA-viruses belonging to the Astroviridae, Picornaviridae, and Coronaviridae families; the Avulavirinae subfamily; and the Rotavirus genus that might be implicated in such health problems. It presents a brief characterization, and possible interspecies transmission of these viruses. We believe that this review article will help clinical signs of infection, isolation methods, occurrence in pigeons and poultry, systemize and summarize knowledge on pigeon enteropathogenic viruses and raise awareness of the importance of disease control in pigeons.

Abstract
The embryonated egg is a complex structure comprised of an embryo and its supporting membranes (chorioallantoic, amniotic, and yolk). The developing embryo and its membranes provide a diversity of cell types that allow for the successful replication of a wide variety of different viruses. Within the family Coronaviridae the embryonated egg has been used as a host system primarily for two avian coronaviruses within the genus Gammacoronavirus, infectious bronchitis virus (IBV) and turkey coronavirus (TCoV). IBV replicates well in the embryonated chicken egg, regardless of inoculation route; however, the allantoic route is favored as the virus replicates well in epithelium lining the chorioallantoic membrane, with high virus titers found in these membranes and associated allantoic fluids. TCoV replicates only in epithelium lining the embryo intestines and bursa of Fabricius; thus, amniotic inoculation is required for isolation and propagation of this virus. Embryonated eggs also provide a potential host system for detection, propagation, and characterization of other, novel coronaviruses.

Abstract
Coronavirus is a severe infectious disease (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and has led to increased mortality worldwide. Multiple reports have been published citing that gastrointestinal symptoms are common in patients with COVID-19 infection. It has also been found that the ACE2 receptor of SARS-CoV-2 is expressed more in the pancreas than the lungs. Despite this, little attention has been paid to the extent and details of pancreatic injury caused by COVID-19. Lack of awareness regarding the COVID-19 status of patients presenting with pancreatitis may expose healthcare workers to SARS-CoV-2 while performing interventions to manage complications of pancreatitis such as necrosis. We report a case of COVID-19-induced acute necrotising pancreatitis in the absence of any known risk factors.

Abstract
Background The coronavirus 2019 (COVID-19) pandemic has posed unique challenges in healthcare. In obstetrics, there is little information available to guide practice. As new data emerge, the spectrum of initial presenting symptoms has expanded from fever, cough, and dyspnea to gastrointestinal and other symptoms in both pregnant and non-pregnant patients. Case A 36-year-old woman, G4P2, at 33 weeks of gestation presented very early in the COVID-19 course with four days of cough and fever, without recent travel or known exposure. She appeared well, with stable vital signs, and was sent home to self-quarantine after a specimen for COVID-19 testing was collected. Two days later, she presented with nausea, vomiting, and abdominal pain, and was diagnosed with acute pancreatitis. Conclusion To date, no cases of human pancreatitis have been identified as related to a COVID-19 infection, although multiple other gastrointestinal symptoms have been described. Given the lack of other etiology, we consider the possibility that patient's acute pancreatitis could be secondary to COVID-19 infection. COVID-19 has a variety of different presentations, including gastrointestinal symptoms. Nausea, vomiting, and epigastric pain in pregnancy can have many different etiologies and should be thoroughly evaluated. Pancreatitis can have a viral etiology, including COVID-19.

A 25-year-old female yellow-naped Amazon parrot ( Amazona auropalliata) was presented for an acute onset of lethargy, ptyalism, and regurgitation. Results of hematologic testing and plasma biochemical analysis revealed severe leukopenia and heteropenia with toxic heterophils and marked hyperamylasemia and hypoproteinemia, consistent with gastrointestinal dysfunction. Survey radiograph findings were suggestive of coelomic effusion. Results of a contrast-enhanced computed tomography (CT) scan revealed a tubular, irregularly marginated structure along the medial aspect of the duodenum, consistent with an inflamed pancreas. The bird died soon after CT imaging, and acute necrotizing pancreatitis and pancreatic coagulative necrosis were observed at necropsy. This report describes the use of a less-invasive modality such as CT to aid in the antemortem diagnosis of acute pancreatitis in a psittacine bird. Pancreatitis should be considered a differential diagnosis in birds with gastrointestinal signs and coelomic effusion visualized on radiography, and the observation of an enlarged inflamed pancreas in the absence of a defined pancreatic mass on CT.

Abstract
Galliformes and columbifomes are closely associated with humans and some species have been domesticated for well over 5000 years. Both orders remain diverse, ranging from the common domestic poultry species (e.g., chicken, turkey, and squabs) to the more exotic species found in the wild and in zoological collections. While many species have been benefited from human activities and have increased their ranges, others have declined in numbers and some have become threatened (e.g., Trinidad piping-guan and wood quail) or even extinct (e.g., dodo and passenger pigeon). Nondomestic galliformes and columbiformes are susceptible to many of the same diseases that occur in domestic species, yet predisposition may be different. Furthermore, disease prevalence depends on exposure and potential risk factors. Infectious diseases that tend to be more common under intensive commercial production may not pose as great a risk to exotic and free-living species.

Abstract
In order to investigate the pancreatic lesions caused by the infection with either H7N1 or H7N3 low-pathogenicity avian influenza viruses, 28 experimentally infected turkeys were submitted for histopathology, immunohistochemistry, haematobiochemistry and real-time reverse transcriptase polymerase chain reaction after different days post-infection (DPI). The localization of viral antigen and the measurement of insulin and glucagon expression in the pancreas were assessed to verify the progression from pancreatitis to metabolic disorders, such as diabetes. At the early infection phase (4-7 DPI), a severe acute necrotizing pancreatitis was recognized. During the intermediate phase (8-17 DPI), a mixed acute/chronic change associated with regenerative ductular proliferation was observed. A loss of pancreatic islets was detected in most severe cases and viral antigen was found in the pancreas of 11/28 turkeys (4-10 DPI) with the most severe histological damage. In turkeys euthanized at 39 DPI (late phase), a chronic fibrosing pancreatitis was observed with the reestablishment of both the exocrine and the endocrine pancreas. Insulin and glucagon expression manifested a progressive decrease with subsequent ductular positivity. Haematobiochemistry revealed increased lipasemia in the first week post-infection and hyperglycaemia in the second, with a progressive normalization within 21 DPI. This study allowed the identification of progressive virus-associated exocrine and endocrine pancreatic damage, suggesting that influenza virus might be responsible for metabolic derangements. Moreover, it highlighted a remarkable post-damage hyperplastic and reparative process from a presumptive common exocrine/endocrine precursor. This potential regeneration deserves further investigation for its relevance in a therapeutic perspective to replace lost and non-functional cells in diabetes mellitus.

Abstract
To assess relationships between xanthine oxidase (XOD) and nephropathogenic infectious bronchitis virus (NIBV) infection, 240 growing layers (35 days old) were randomly divided into two groups (infected and control) of 120 chickens each. Each chicken in the control and infected group was intranasally inoculated with 0.2 mL sterile physiological saline and virus, respectively, after which serum antioxidant parameters and renal XOD mRNA expression in growing layers were evaluated at 8, 15 and 22 days post-inoculation (dpi). The results showed that serum glutathione peroxidase and superoxide dismutase activities in the infected group were significantly lower than in the control group at 8 and 15 dpi (p < 0.01), while serum malondialdehyde concentrations were significantly higher (p < 0.01). The serum uric acid was significantly higher than that of the control group at 15 dpi (p < 0.01). In addition, the kidney mRNA transcript level and serum activity of XOD in the infected group was significantly higher than that of the control group at 8, 15 and 22 dpi (p < 0.05). The results indicated that NIBV infection could cause the increases of renal XOD gene transcription and serum XOD activity, leading to hyperuricemia and reduction of antioxidants in the body.

Abstract
It is essential to understand the latest situation regarding avian coronaviruses (ACoVs), commonly referred to as the well-known avian infectious bronchitis virus (IBV), given that new and diverse types of IBV are continually being identified worldwide, particularly ones that are isolated from commercial poultry and associated with a wide range of disease conditions. The existing IBVs continue to evolve in various geographic areas in Asia, which results in the recombination and co-circulation between IBV types. This makes it increasingly difficult to prevent and control IBV infections, despite routine vaccination. Some ACoVs have also been identified in other avian species and they may pose a threat of cross-transmission to commercial sectors. The present review provides an overview of IBV circulation and the dynamic emergence of new variants found throughout Asia via the recombination of IBV strains. In addition to commercial poultry, backyard poultry and free-ranging birds may serve as a ‘hub’ for ACoV transmission within a particular area. These birds may be capable of spreading viruses, either to areas of close proximity, or to remote places via migration and trade.

Host tissue and glycan binding specificities of avian viral attachment proteins using novel avian tissue microarrays. PLoS One 2015; 10:e0128893.

Abstract
The initial interaction between viral attachment proteins and the host cell is a critical determinant for the susceptibility of a host for a particular virus. To increase our understanding of avian pathogens and the susceptibility of poultry species, we developed novel avian tissue microarrays (TMAs). Tissue binding profiles of avian viral attachment proteins were studied by performing histochemistry on multi-species TMA, comprising of selected tissues from ten avian species, and single-species TMAs, grouping organ systems of each species together. The attachment pattern of the hemagglutinin protein was in line with the reported tropism of influenza virus H5N1, confirming the validity of TMAs in profiling the initial virus-host interaction. The previously believed chicken-specific coronavirus (CoV) M41 spike (S1) protein displayed a broad attachment pattern to respiratory tissues of various avian species, albeit with lower affinity than hemagglutinin, suggesting that other avian species might be susceptible for chicken CoV. When comparing tissue-specific binding patterns of various avian coronaviral S1 proteins on the single-species TMAs, chicken and partridge CoV S1 had predominant affinity for the trachea, while pigeon CoV S1 showed marked preference for lung of their respective hosts. Binding of all coronaviral S1 proteins was dependent on sialic acids; however, while chicken CoV S1 preferred sialic acids type I lactosamine (Gal(1-3)GlcNAc) over type II (Gal(1-4)GlcNAc), the fine glycan specificities of pigeon and partridge CoVs were different, as chicken CoV S1-specific sialylglycopolymers could not block their binding to tissues. Taken together, TMAs provide a novel platform in the field of infectious diseases to allow identification of binding specificities of viral attachment proteins and are helpful to gain insight into the susceptibility of host and organ for avian pathogens.

Abstract
Avian coronaviruses of the genus Gammacoronavirus are represented by infectious bronchitis virus (IBV), the coronavirus of chicken. IBV causes a highly contagious disease affecting the respiratory tract and, depending on the strain, other tissues including the reproductive and urogenital tract. The control of IBV in the field is hampered by the many different strains circulating worldwide and the limited protection across strains due to serotype diversity. This diversity is believed to be due to the amino acid variation in the S1 domain of the major viral attachment protein spike. In the last years, much effort has been undertaken to address the role of the avian coronavirus spike protein in the various steps of the virus' live cycle. Various models have successfully been developed to elucidate the contribution of the spike in binding of the virus to cells, entry of cell culture cells and organ explants, and the in vivo tropism and pathogenesis. This review will give an overview of the literature on avian coronavirus spike proteins with particular focus on our recent studies on binding of recombinant soluble spike protein to chicken tissues. With this, we aim to summarize the current understanding on the avian coronavirus spike's contribution to host and tissue predilections, pathogenesis, as well as its role in therapeutic and protective interventions.

Abstract
We examined 884 wild birds mainly from the Anseriformes, Charadriiformes and Galliformes orders for infectious bronchitis (IBV)-like coronavirus in Poland between 2008 and 2011. Coronavirus was detected in 31 (3.5%) of the tested birds, with detection rates of 3.5% in Anseriformes and 2.3% in Charadriiformes and as high as 17.6% in Galliformes. From the 31 positive samples, only 10 gave positive results in molecular tests aimed at various IBV genome fragments: five samples were positive for the RdRp gene, four for gene 3, eight for gene N and eight for the 3'-untranslated region fragment. All analysed genome fragments of the coronavirus strains shared different evolutionary branches, resulting in a different phylogenetic tree topology. Most detected fragment genes seem to be IBV-like genes of the most frequently detected lineages of IBV in this geographical region (i.e. Massachusetts, 793B and QX). Two waves of coronavirus infections were identified: one in spring (April and May) and another in late autumn (October to December). To our knowledge this is the first report of the detection of different fragment IBV-like genes in wild bird populations.

Abstract
As part of our ongoing surveillance program, 40 field strains of avian infectious bronchitis virus (IBV) were isolated from dead or diseased chicken flocks in different areas of China between 2009 and 2010. S1 glycoprotein genes of these strains were sequenced and analyzed with 38 strains published in GenBank. S1 genes of these isolated strains and the vaccine strains showed nucleotide homologies ranging from 65.2 to 82% and amino acid homologies ranging from 58.4 to 81.9%. Meanwhile, Chinese IBV strains isolated in this study, which were mainly nephropathogenic, could be separated into six variant lineages (CH I-CH VI), and current vaccine strains used in China formed Mass variant lineage that is evolutionarily distant from Chinese isolates. Moreover, CK/CH/GD/NC10, CK/CH/GD/KP10, and our previous isolates TC07-2 formed the CH VI lineage, showing larger evolutionary distances from other strains. Taken together, these findings suggested that various variant lineages were co-circulating in China now, and appeared to be continuously evolving, alternative indigenous vaccines indeed need for effective control of IB in China.

Abstract
An increasing incidence of enteric disorders clinically suggestive of the poult enteritis complex has been observed in turkeys in France since 2003. Using a newly designed real-time reverse transcriptase-polymerase chain reaction assay specific for the nucleocapsid (N) gene of infectious bronchitis virus (IBV) and turkey coronaviruses (TCoV), coronaviruses were identified in 37% of the intestinal samples collected from diseased turkey flocks. The full-length spike (S) gene of these viruses was amplified, cloned and sequenced from three samples. The French S sequences shared 98% identity at both the nucleotide and amino acid levels, whereas they were at most 65% and 60% identical with North American (NA) TCoV and at most 50% and 37% identical with IBV at the nucleotide and amino acid levels, respectively. Higher divergence with NA TCoV was observed in the S1-encoding domain. Phylogenetic analysis based on the S gene revealed that the newly detected viruses form a sublineage genetically related with, but significantly different from, NA TCoV. Additionally, the RNA-dependent RNA polymerase gene and the N gene, located on the 5' and 3' sides of the S gene in the coronavirus genome, were partially sequenced. Phylogenetic analysis revealed that both the NA TCoV and French TCoV (Fr TCoV) lineages included some IBV relatives, which were however different in the two lineages. This suggested that different recombination events could have played a role in the evolution of the NA and Fr TCoV. The present results provide the first S sequence for a European TCoV. They reveal extensive genetic variation in TCoV and suggest different evolutionary pathways in North America and Europe.

Abstract
The attenuation of infectious bronchitis (IB) QX-like virus strain L1148 is described. The virus was passaged multiple times in embryonated specific pathogen free (SPF) chicken eggs, and at different passage levels samples were tested for safety for the respiratory tract and kidneys in 1-day-old SPF chickens. There was a clear decrease in pathogenicity for the respiratory tract and kidneys when the virus had undergone a large number of passages. Passage level 80 was investigated for safety for the reproductive tract in 1-day-old and 7-day-old SPF chickens. In 1-day-old chickens, 12.5% of the vaccinated birds had macroscopic lesions. No lesions were observed if the chickens had been vaccinated at 7 days of age. Passage level 80 was investigated for its ability to spread from vaccinated to non-vaccinated chickens and for dissemination in the body. The virus was able to spread from vaccinated chickens to groups of non-vaccinated chickens, and in the vaccinated birds the virus was found frequently in oro-pharyngeal and cloacal swabs. A fragment of the hypervariable region of the S1 protein of passage level 80 was sequenced and revealed nucleotide changes resulting in two amino acid substitutions. Passage level 80 was given additional passages to levels 82 and 85. Both passage levels were tested for efficacy in SPF chickens and passage level 85 was tested for efficacy in commercial chickens with maternally derived antibodies (MDA) against a challenge with QX-like strain IB D388. In both SPF chickens and chickens with MDA, the vaccines based on strain IB L1148 were efficacious against challenge.

Abstract
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 S1 protein. In the first step, all samples were submitted to RNA extraction, RT-PCR, and nested PCR. Next, only the positive nested-PCR samples were propagated in specific-pathogen-free (SPF) embryonated chicken eggs for virus isolation. Positive samples were then sequenced and analyzed using a molecular phylogeny approach. Tracheal swab samples were collected from 23 different domestic chickens distributed in three regions of Brazil, in the period between 2003 and 2009. Also analyzed were six swab samples (tracheal and cloacal) from asymptomatic pigeons (Columba livia), caught in an urbanized region in southeastern Brazil. The study revealed two major phylogenetic groups: one clustered with the Massachusetts vaccine serotype and another joined with the D207 strain. Interestingly, samples grouped with the Connecticut and Arkansas serotypes were also found. Pigeon isolates clustered with the Massachusetts serotype showed significant similarity (close to 100%) to those obtained from chickens. Only one pigeon isolate was seen to be grouped with the Connecticut serotype, and no correlation was observed between sample grouping and region origin. Understanding the diversity of genotypes and eco-epizootiology of the disease in different environments is expected to be helpful for vaccine production aimed at the main circulating variants. In this respect, one could also expect benefits in the management of other bird species that may act as avian coronavirus reservoirs.

Abstract
A survey of infectious bronchitis virus (IBV) genotypes in poultry flocks in selected countries in Western Europe was carried out between March 2002 and December 2006. Identification of IBV was by reverse transcriptase-polymerase chain reaction of RNA extracted from oropharyngeal swabs taken from poultry flocks exhibiting signs of clinical disease thought to be attributable to IBV. Part of the hypervariable S1 gene of IBV was sequenced to differentiate between the various genotypes. During the survey, 4103 samples were processed, of which 2419 (59%) were positive for IBV. The predominant IBV genotypes detected were 793B and Massachusetts. The third and fourth most common genotypes were two new economically important field types: Italy02, and a virus similar to genotypes originally detected in China called QX. Analysis of the partial S1 sequences of the genotypes detected suggested that approximately 50% of all 793B, Massachusetts types and D274 IBVs were identical to the homologous commercially available live vaccines. Since 2004 the prevalence of Italy02 (present in all countries from which samples were received) has been declining in all countries except Spain, where it appeared to be the predominant genotype. Since 2004 an IBV genotype has been detected in Holland, Germany, Belgium and France similar to QX and the incidence has increased. QX was not detected in the United Kingdom or Spain. When detections thought to be attributable to vaccines were removed, the dominant genotype in France and Europe overall was 793B; in Germany, Holland and Belgium, it was QX-like IBV; and in the United Kingdom and Spain the dominant genotype was Italy02. The present study is the first to identify the prevalence of both Italy02 and QX field-type variants in poultry flocks in Western Europe. Several novel genotypes have also been detected.

Twelve infectious bronchitis virus (IBV) isolates obtained from commercial chickens in China between 2005 and 2006 were characterized by reverse transcriptase-polymerase chain reaction (RT-PCR) and the sequencing of the entire S1 gene. CK/CH/LSD/05I--an IBV variant, which was unlike the nephropathogenic IBV isolates found in China--exhibited an affinity for the respiratory tract. The variant was identified by phylogenic analysis and basic local alignment search tool (BLAST) searches of the entire S1 gene and by the vaccination-challenge test that was performed using heterologous strains. Further, it was demonstrated that the commercially used H120 vaccine did not provide sufficient protection against this variant; however, the attenuated heterologous IBV tl/CH/LDT3/03 P120, whose parent virus was isolated in China, showed a better efficacy of protection against CK/CH/LSD/05I. This study thus may demonstrate that the use of a combination of commercially available vaccines or of attenuated heterologous strains would provide satisfactory protection against the variant CK/CH/LSD/05I. In addition, the study also revealed that IBV strains exhibiting different pathogenicities were found cocirculating in the chicken flock in China.
