| a survey of disease in five commercial flocks of meat breeder chickens. | causes of sickness and death in approximately 30,000 chickens in 5 meat breeder flocks were investigated between may 1979 and april 1980. approximately 23% of disease was due to neoplasms; 81% of these were marek's disease despite vaccination against this infection. other frequent diagnoses included cellulitis (15%), respiratory disease (14%), lesions of the reproductive tract (11%) and tenosynovitis/arthritis (9%). antibodies to mycoplasma gallisepticium, avian adenovirus, infectious bursal dis ... | 1984 | 6704066 |
| antigenic and sequence heterogeneity of infectious bursal disease virus strains isolated in australia. | six recently isolated field strains of infectious bursal disease virus (ibdv) were compared to vaccine strains at the antigenic and genetic level to ascertain the level of heterogeneity among australian ibdv strains. five strains, 01/94, 02/95, 03/95, 04/95 and 08/95, isolated at four locations in the state of victoria, were antigenic variants. they failed to react with monoclonal antibodies directed against two different epitopes on the vp2 protein which were present in vaccine strains and one ... | 2000 | 10893155 |
| confirmation of the existence of two distinct genetic groups of infectious bursal disease virus in australia. | to characterise infectious bursal disease viruses (ibdvs) prevalent at major commercial sites throughout australia and to compare the nucleic acid sequences of local strains of ibdv with those of characterised overseas strains. | 2002 | 12465828 |
