“…In this study, our analyses revealed that the CK/CH/JS/TAHY strain induced severe pathogenicity in 1-day-old SPF chickens with severe kidney and tracheal lesions. Our results confirmed the ability of CK/CH/JS/TAHY strain to induce both respiratory and renal disease which was consistent with QX-like characteristic symptoms (Zou et al, 2010;Bande et al, 2017). As reported, IBV replicated in many respiratory tissues such as trachea, lungs, and air sacs and some urogenital tissues including kidney and even in liver and brain (Cavanagh, 2003;Feng et al, 2012).…”

Avian infectious bronchitis is a serious and highly contagious disease caused by infectious bronchitis virus (IBV). We isolated a highly virulent IBV strain (CK/CH/JS/TAHY) from kidneys of diseased chickens. Phylogenetic analysis based on the S1 gene revealed that CK/CH/JS/TAHY clustered with the QX-like type. The S1 gene has 1,620 nucleotides and encoded a polypeptide of 540 amino acids with typical coronavirus cleavage recognition sites of HRRR. About 1-day-old specific pathogen-free White Leghorn chickens inoculated with CK/CH/JS/TAHY at 10 5.5 EID 50 exhibited clinical signs including coughing, sneezing, nasal discharge, and tracheal vocalization accompanied by depression with 84% mortality and 100% morbidity. The kidneys of dead birds were swollen and pale and exhibited severe urate deposition. Histopathological examination revealed kidney hemorrhages, multifocal necrosis of the renal tubules and trachea with cilia loss, sloughing of epithelial cells, and edema of the lamina propria. IBV-specific antibodies appeared at 10 D post-infection. Chickens vaccinated with a CK/CH/JS/TAHY oil-emulsion vaccine showed 26.7% morbidity and 3% mortality indicating a protective effect. In conclusion, the IBV strain is a virulent avian IBV and that exhibited severe pathogenicity in chickens and is a vaccine candidate to prevent infection by Chinese QX-like nephropathogenic IBV strains.

“…S1 nucleotide sequences of different serotypes differ up to 25% (Cavanagh, 2005). There are 3 hypervariable regions described within the S1 subunit sequence (HVR I aa 38-67, HVR II aa 91-141, HVR III aa 274-387) (Cavanagh et al, 1988), in which most nucleotide substitutions were located (Bande et al, 2017;Lin and Chen, 2017). It was shown that comparison of HVR I and whole S1 gene resulted in the same grouping data (Wang and Huang, 2000).…”

The infectious bronchitis virus Middle-East GI-23 lineage (Var2-like) was observed on a German broiler farm, for the first time. The animals suffered from respiratory and nephropathogenic disease. Gross lesions observed during necropsy included tracheitis, aerosacculitis, and nephritis.Tracheal swabs were tested positive for infectious bronchitis virus Middle-East GI-23 lineage (Var2like) by PCR. Furthermore, sequence analysis of the S1 spike protein showed close relationship to the commercially available vaccine TAbic IBVAR206 and polish isolates.

“…Infectious bronchitis virus (IBV) and Newcastle disease virus (NDV) are 2 of the most important viruses seriously affecting the poultry industry and causing huge economic losses worldwide (Bande et al, 2017;Brown and Bevins, 2017). IBV and NDV belong to the Gammacoronavirus of the Coronaviridae family and the Avulavirus of the Paramyxoviridae family, respectively (http://www.ictv.global).…”

Infectious bronchitis virus (IBV) andNewcastle disease virus (NDV) are both important viruses seriously affecting poultry industry worldwide. In this study, reverse-transcription LAMP (RT-LAMP) was combined with lateral flow dipstick (LFD) forming a novel detection tool which could simultaneously detect IBV and NDV visually. Primers targeted the 5 -untranslated region (5 -UTR) of IBV genome and the conserved region of NDV large polymerase gene (LP). The specificity and sensitivity of this multiple reverse transcription-LAMP-LFD (mRT-LAMP-LFD) assay were compared with those of conventional RT-PCR, nested RT-PCR (nRT-PCR), quantification RT-PCR (qRT-PCR), and RT-LAMP monitored by electrophoresis. No non-specific amplifications were observed when the assays were tested with unrelated viruses. According to the sensitivity study, when detecting IBV or NDV alone, the lowest detection limits of mRT-LAMP-LFD were 10 0.8 IBV RNA copies/reaction and 10 0.7 NDV RNA copies/reaction. Furthermore, when detecting IBV and NDV simultaneously, the lowest detection limit was the same as that of the single detection assays. In the clinical sample study, mRT-LAMP-LFD performed the best among these assays. When tested with IBV or NDV single infected samples, the mean detection rates were 98.65% and 97.25%, respectively. In the IBV and NDV co-infected sample study, the mean detection rates of IBV and NDV were both 95%. This study showed that mRT-LAMP-LFD was a promising qualitative detection tool suitable for field single or multiple IBV and NDV detection.
