Avian infectious bronchitis virus.
Infectious bronchitis virus (IBV) is prevalent in all countries with an intensive poultry industry, with the incidence of infection approaching 100% in most locations. Vaccination is only partially successful due to the continual emergence of antigenic variants. At many sites, multiple antigenic types are simultaneously present, requiring the application of multiple vaccines. Although many coun...
متن کاملRapid detection and identification of avian infectious bronchitis virus.
A rapid and sensitive method for the detection and unambiguous typing of infectious bronchitis virus (IBV) is described. RNA was isolated from IBV-infected allantoic fluid and was transcribed into cDNA. This cDNA was amplified by the polymerase chain reaction. The polymerase chain reaction products were subsequently analyzed on an agarose gel. The presence of IBV-specific RNA in the allantoic f...
متن کاملA simple and rapid strip test for detection of antibodies to avian infectious bronchitis virus.
A simple gold-immunochromatographic assay (GICA) based on indirect reaction format was developed for rapid detection of antibodies against avian infectious bronchitis virus (IBV). The detection time of IBV IgG by the GICA was less than 10 min, whereas the HI test and the enzyme-linked immunosorbent assay (ELISA) require 1-2 hr. Reference sera against newcastle disease virus, infectious bursal d...
متن کاملEmergence of variant avian infectious bronchitis virus in India
Background: Infectious bronchitis virus (IBV) is the etiological agent of an acute and highly contagious disease. Infectious bronchitis (IB) affects chicken of all ages and poses major economic loses to the poultry industry worldwide. The continuous evolution of the spike protein (S1) of IBV is responsible for the prevalence of many serotypes/genotypes around the world. Multipl...
متن کاملDetection of Infectious Bronchitis Virus in Allantioc Fluid by Rapid Hemagglutination Test.
To detect the presence of infectious bronchitis virus (IBV) in infected allantoic fluid (AF) of SPF embryonated eggs rapid hemagglutination (HA) activity after treatment with neuraminidase enzyme was used. Twenty IBV suspected materials were inoculated in SPF embryonated eggs via chorioallantoic cavity. Harvested AFs were treated with neuraminidase enzyme and the presence of IBV was detected by...
