Infectious Bursal Disease and Spirochetosis in Pullet Chicks
Avian Diseases, 1987Infectious bursal disease and spirochetosis were diagnosed simultaneously in a flock of 100 six-week-old babcock pullet chicks. Larvae of the fowl tick Argas persicus were found on the bodies of the chicks. Thirty-nine of the chicks died 5 days after the onset of clinical signs.

Molecular Detection and Differentiation of Infectious Bursal Disease Virus
Avian Diseases, 2007Vaccination of hens, with the subsequent maternal immunity imparted to chicks, is the primary means of controlling infectious bursal disease virus (IBDV). Effective vaccination depends on rapid and accurate diagnosis of the subtype present in a flock because vaccines based on the classic subtype of IBDV can fail to protect against challenge with a ...

Molecular Characterization of Iranian Infectious Bursal Disease Viruses
Avian Diseases, 2008This study was conducted to characterize nine infectious bursal disease virus (IBDV) isolates from Iran. A reverse transcriptase-polymerase chain reaction (RT-PCR) procedure was used to amplify a 743-bp fragment of the VP2 gene hypervariable region from IBDV field isolates.

Infectious Bursal Disease Virus (IBDV)
2019Infectious bursal disease virus (IBDV) is one of the most important viral pathogens of chickens. This virus causes great economic losses to the poultry industry due to factors like high mortality rates and poor growth performance of the affected chickens.

Immunosuppression induced by infectious bursal disease virus
Veterinary Immunology and Immunopathology, 1991Immunosuppression caused by infectious bursal disease virus (IBDV) is of major interest because of the widespread occurrence of the infection in commercial chickens. Infection with IBDV at an early age significantly compromises the humoral and local immune responses of chickens. The cellular immune response is also compromised by apparently to a lesser

Infectious Bursal Disease Virus and Antarctic Birds
2009The geographic isolation of the Antarctic continent coupled with the extreme climate has historically been assumed to protect the indigenous Antarctic wildlife from exposure to infectious agents found among animals in more temperate regions. However, with the number of tourists visiting the region more than doubling in the last 10 years (IAATO 2004 ...
