The influence of major histocompatibility complex genotypes on resistance to Pasteurella multocida and Newcastle disease virus in turkeys.
Sublines homozygous for each of four MHC haplotypes were developed from randombred control populations of turkeys and challenged with Pasteurella multocida (capsular serogroup a, somatic serotype 3, 4) at 6 wk of age or Newcastle disease virus (NDV; Texas GB strain) at 4 wk of age. In addition, individuals from a randombred control line (RBC2) and a subline (F) of RBC2 long-term selected for in...
متن کاملThe effect of mixed live vaccines of Newcastle disease and infectious bronchitis on systemic and local antibody responses in chickens
In the present study, 360 male day-old broiler chicks were used to determine the effect of mixed livevaccines of Newcastle disease (ND) and infectious bronchitis (IB) on serum and local antibody responses toIB. Chicks were randomly divided into 12 treatment groups of 3 replicates and reared for 40 days on floorpens. Groups 1 to 5 received mixed ND and IB vaccine. Groups 7 to 11 received IB vacc...

Background and Aims: The objective of this study was to investigate the effects of Newcastle Disease and Infectious Bronchitis vaccination programs in chickens. Materials and Methods and Results: In the present study, 225 day-old broiler chicks divided into 5 groups. The groups were submitted to vaccinations, except for the non-vaccinated control group. The chickens in the groups 1 were kept as...

Experimental Infection of Turkeys with A Virulent Newcastle Disease Virus Isolated from Broiler Chickens
Newcastle disease (ND) is a highly contagious infection of many avian species, mainly chickens and turkeys, with a devastating impact on worldwide poultry production. The ND accounts for heavy losses in Iranian poultry flocks. There are some reports regarding the epidemiology of this infection in Iran. This study was performed to investigate the infection of turkeys with a Newcastle disea...
