The 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...

متن کاملEffect of the Commercial Mixed Live Newcastle Disease and Infectious Bronchitis Vaccines and the Use of Two Separate Vaccines Given Simultaneously on Systemic Antibody Responses
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...
متن کاملCross-Protective Immune Responses Elicited by Live Attenuated Influenza Vaccines
The desired effect of vaccination is to elicit protective immune responses against infection with pathogenic agents. An inactivated influenza vaccine is able to induce the neutralizing antibodies directed primarily against two surface antigens, hemagglutinin and neuraminidase. These two antigens undergo frequent antigenic drift and hence necessitate the annual update of a new vaccine strain. Be...
