The viral susceptibility range of a poikilothermic cell line derived from the fathead minnow (Pimephales promelas) (FHM) to infection by a number of homoiothermic viruses representing most of the presently recognized viral groups and a member of the psittacosis-lymphogranuloma-trachoma group of agents was studied. All infectious agents, except poliovirus types 1 and 3, infectious bursal agent, ...

Introduction: Infectious bronchitis (IB), caused by infectious bronchitis virus (IBV), is an acute and highly contagious disease in chickens. IBV is mainly considered a respiratory infection, other clinical manifestations, including renal, enteric and reproductive signs can be observed. Aim: Since there has been no study on evaluation of changes in biochemical parameters during IB infection, th...

Background: Avian infectious bronchitis (IB) is a highly contagious viral disease which affects the poultry industry. The virus exists in a wide variety of genotypes, and phylogenetic analysis has been used to classify infectious bronchitis virus (IBV) strains. Aims: The object of the study is a molecular characterization of circulating IBV in Afghanistan as a ...

Infectious bronchitis (IB) is a major threat to the global poultry industry. Despite availability of commercial vaccines, IB epidemic has not been effectively controlled. The exploration novel IBV vaccines may provide new way prevent and control IB. In this study, BLP-S1, bacterium-like particle displaying S1 subunit infectious virus (IBV), was constructed using GEM-PA surface display system. i...

The synergistic role of infectious bronchitis virus (IBV) and mixed infections of Mycoplasma synoviae (MS) and Escherichia coli (EC) in the airsacculitis syndrome was evaluated in gnotobiotic chickens. Relative air sac lesion score indexes, in descending order of severity, from various combinations of organisms were: 9.5-IBV, MS, EC; 6.8-IBV, EC; 4.5-IBV, MS; 2.7-IBV; and 0.5-MS, EC. Infectious...
