All groups at 18 days were challenged with IBD intermediate strain. Mortality, gross and microscopic lesion, bursal index, clinical signs and immune response (ELISA) were evaluated. Some morphological characteristics and benefits were founded inherent to vaccination. VAXXITEK is a registered trademark of Merial in the United States of America and elsewhere. Avian Bulletin: Volume 1, Number 3, Page 7 of 94
2 V. Perez et al. Merial Avian Bulletin 3 (2008) Page 4 to 7 Introduction The IBD virus infects the lymphocytes of the cloacal bursa producing immunosuppression. The live vaccines against the IBD replicate in the cloacal bursa producing macroscopic and histological lesions, as well as serological response. The HVT virus permanently infects the bursal lymphocytes. Therefore, the HVT virus, containing the VP2 gene, presents the antigen of IBD, without causing bursal lesions. The objective of this study is to evaluate the serological response and the serological response and the macroscopic and histological integrity of the bursa in birds vaccinated with a HVT vectored IBD vaccine, administered both in ovo and subcutaneously, and challenged with an IBD virus of intermediate virulence at 18 days of age. Methods and material 150 embryonated chicken eggs and 150 one day-old broiler chickens were divided into three groups respectively. The birds were vaccineted with a vectored vaccine or bivalent vaccines in ovo at 18 days of embryonation or at one day of age by subcutaneous route. 1). Table1. Treatments by age, type of vaccine and vaccination route. Turkey herpesvirus vectored vaccine contains the VP2 gene of IBD virus (VAXXITEK 4 ) (Merial Limited). Bivalent Vaccine is composed of HVT and IBD (Lukert strain) (Merial Limited). BURSA-VAC (Schering-Plough Animal Health, Millsboro, Delaware, USA); an IBD vaccine strain of VAXXITEK HVT+IBD is a registered trademark of Merial in the United States of America and elsewhere. similar intermediate virulence to the field strains in Mexico, with a titre EID 50% = was used as the challenge virus. Serums for analysis were taken for ELISA. The morphometric index (MI) was determined by dividing the weight of the cloacal bursa by the weight of the bird (Table 2). The histological study was done and the diameter of the lymphoid follicles of cloacal bursa was measured. Results The ELISA titers (Figure 1) at 23 and 31 days of age, the morphometric index (Figure 2) and the diameter of the lymphoid bursa follicles (Figure 3) at 31 and 43 days of age were higher in the birds vaccinated with the vectored vaccine (P<0.05). At 43 days of age, the birds vaccinated with bivalent vaccine in ovo had higher titers (P<0.05) (Figure 1). Conclusions Maternal antibodies did not influence the serological response produced by the vectored vaccine or the bivalent vaccine. In the face of the challenge, the vectored vaccine had a better serological response than the bivalent vaccine. Also, the vectored vaccine resulted in better bursal integrity both macroscopically and histologically.
