LAYERS '99, PART I: REFERENCE OF 1999 TABLE EGG LAYER MANAGEMENT IN THE U.S.
Provedor de dados: 31
The National Animal Health Monitoring System (NAHMS) is sponsored by the USDA:APHIS:Veterinary Services (VS). The NAHMS Layers '99 Study was designed to provide information about the nation's layer population for education and research purposes. The USDA's National Agricultural Statistics Service (NASS) collaborated with VS to select a statistically-valid sample from 15 states for Layers '99. The 15-state target population accounted for over three-quarters of the table egg layers in the U.S. as of December 1, 1998. The study was limited to companies with 30,000 or more layers. While the majority of farm sites were contract farms (61.0 percent), the majority of birds were located on company owned farms (72.6 percent), indicating that company owned farms...

Europe: history, current situation and control measures for infectious bronchitis
Provedor de dados: 89
Autores: Jones,RC.
The emergence and nature of different strains of infectious bronchitis virus (IBV) in Europe are described. Infectious bronchitis (IB) is the most important endemic viral respiratory disease where highly pathogenic Newcastle disease and avian influenza are not present. IB was first described in the UK in 1948 and identified as Massachusetts type. In the 1970s and 80s new serotypes were reported in Holland and elsewhere and new vaccines were developed. The 1990s saw the emergence of the major variant commonly called 793B, again needing a new vaccine. Two novel types have been recognised since 2000, Italy 02 and QX. Italy 02 appears to be well controlled by the use of two different live vaccines (H120 and the 793B-related 4/91) while for QX, associated with...

Effect of associated vaccines on the interference between Newcastle disease virus and infectious bronchitis virus in broilers

The phenomenon of viral interference between live vaccines against Newcastle Disease and infectious bronchitis has been reported since the 50's and many researchers have reported its prejudicial effects on avian immunization. Therefore, this study evaluated the effect of associated vaccines on the interference between Newcastle disease virus (NDV) and infectious bronchitis virus (IBV) in broilers. There were 400 broiler chicks divided into five groups. The groups were submitted to mono or polyvalent vaccinations against IBV and NDV, except for the non-vaccinated control group (CG). Sera were collected at 35 and 45 days of age and submitted to serologic tests to assess antibody levels. It was observed the occurrence of interference in the immune response...

Elisa evaluation of the levels of antibodies against Infectious Bronchitis Virus in laying hens using egg yolk as substrate
Provedor de dados: 89
Autores: Rauber,RH; Flôres,ML; Pereira,CE; Grigulo,M.
The present work was carried out to compare Infectious Bronchitis Virus (IBV) antibody titers in serum and egg yolk samples from laying hens. Sixty paired blood and egg samples were collected from laying hens of two farms. Serum samples were frozen, while egg yolk samples were diluted (1:500) before freezing. Serum and yolk samples were tested for the presence of IBV antibodies by indirect ELISA (commercial kit) and titers were compared by a correlation test (alpha=0.05). There was a high correlation (r=0.62) between the two kinds of samples, which means that titers of IBV antibodies in the egg yolk and in serum samples are quite the same. Considering that blood collection causes deep stress that leads to economic losses, and since eggs are collected daily...

Murine hybridomas producing IgG1 monoclonal antibodies (Mabs) against N and S2 proteins (53KDa and 82KDa, respectively) from avian infection bronchitis virus (IBV) strain M41 were generated by the fusion of a myeloma cell line (Sp2/0-Ag14) with spleen cells from Balb/c mice previously immunized with whole virus IBV M41. Post-fusion screening criterion was by ELISA and 36 positive hybrids were generated after fusions. Two hybrids specific to N (N3F10) and S2 (S12B2) proteins from M41 (serotype Massachusetts) were selected by western blotting. These Mabs recognized the Ark-99 (serotype Arkansas) and A5968 (serotype Connecticut) IBV strains in addition to M41. By ELISA, the Mab against the S2 (S12B2) recognized all reference and Brazilian strains (M41, SE-17,...
