Juranová, R. , Nguyen Thi Nga, L. Kulíková, V. Jurajda: Pathogenicity of Czech Isolates of Infectious Bursal Disease Virus. Acta Vet. Brno, 2001, 70: 425-431. An epidemics of infectious bursal disease (IBD) affected chicken farms in the Czech Republic in the mid nineties. Characteristics of six strains of infectious bursal disease virus (IBDV), isolated from broiler chickens, lying hybrid pulle...

Infectious Bursal Disease (IBD) has been reported in Indonesia since 1983 and become an endemic disease. IBD virus is known to be quite resistant physical chemical reagents compared other viruses, causing this disease hard eradicated. This study aims evaluate the effect of heat disinfectants on viability virus. was conducted using a local isolate IBDV obtained from IRCVS. The exposed disinfecta...

Materials and Methods Infectious bursal disease (IBD) is a highly contagious disease of young chicken caused by infectious bursal disease virus (IBDV), characterized by immunosuppression and mortality generally at 3 to 6 weeks of age [1]. It is economically important to the poultry industry worldwide, due to increased susceptibility to other diseases and negative interference with effective vac...

vp2 gene coding region of a vaccinal strain (d78) of infectious bursal disease virus (ibdv) was clonedin a eukaryotic expression vector, psec tag2a. the gene was placed downstream of ig κ chain leadersequence, under the control of human cytomegalovirus (hcmv) immediate early enhancer and promoter. theconstruct psec tag2a-vp2 was transfected in cos-7 cell line and the expression and secretion of...

The immune response elicited by the oral inoculation of an intermediate strain of infectious bursal disease virus was studied in chickens. A strong over expression of IL-6, IL-8, IFNα and IFNγ was observed in bursa at 3 days post inoculation together with an increase in splenic NO2 release. An influx of T-lymphocytes was also detected.

A multiplex reverse transcription polymerase chain reaction (RT-PCR) was developed and optimized to simultaneously detect 3 subtypes (H5, H7 and H9) of avian influenza virus type A. The developed method was specific to amplify only the HA gene of H5, H7 and H9 of Influenza type A and no amplification with other subtypes of AIV and other avian infectious viruses such as Newcastle disease virus, ...

Infectious bursal disease (IBD) (Gumboro disease) has been described throughout the world, and the socio-economic significance of the disease is considerable world-wide. Various forms of the disease have been described, but typing remains unclear, since antigenic and pathotypic criteria are used indiscriminately, and the true incidence of different types is difficult to determine. Moreover, the...

Infectious bursal disease virus is a relevant avian pathogen that affects poultry production. Here, we report the full-length coding sequence of the Uruguayan strain dIBDV/UY/2014/2202, isolated from a commercial broiler flock. The strain belongs to the distinct IBDV lineage that is widely distributed in South America.
