1. Construction and characterization of a recombinant vaccine encoding the nucleocapsid protein gene of avian infectious bronchitis virus
RESUMO A vacinação é a forma mais utilizada para prevenir a bronquite infecciosa causada pelo vírus da bronquite infecciosa das galinhas (IBV). Contudo, as vacinas convencionais são incapazes de diferenciar aves infectadas de vacinadas. No presente trabalho foi construído, caracterizado, e avaliado como candidato vacinal, um adenovírus recombinante ex

2. Post-hatch fasting and infectious bronchitis vaccination affect growth, gastrointestinal development, and morphometric parameters of the small intestine of broiler breeders up to three weeks of age
ABSTRACT The influence of fasting and vaccination against infectious bronchitis (IB) on growth, gastrointestinal development, and morphometric parameters of the small intestine of newborn broiler breeders was investigated. Weight gain (WG), feed conversion ratio (FCR), gastrointestinal visceral growth, residual yolk sac, and morphometric parameters of the sm

3. Effects of Diets with Graded Levels of Canola Meal on the Growth Performance, Meat Qualities, Relative Organ Weights, and Blood Characteristics of Broiler Chickens
ABSTRACT This experiment was conducted to evaluate the dietary supplementation of canola meal (CM) on the growth performance, carcass characteristics, antibody titers against Newcastle disease virus and Infectious bronchitis virus, and blood profiles of broiler chickens. In total 600 day-old feather-sexed Ross male broiler chicks were randomly assigned into

4. Eggshell apex abnormalities in a free-range hen farm with mycoplasma synoviae and infectious bronchitis virus in Rio de Janeiro state, Brazil
A farm with 3,000 free-range hens between 24 and 65 weeks of age was investigated. These hens were separated in small flocks of 400 to 700 birds, presenting 10 to 23% egg production reduction. Twenty serum samples were collected during the period of drop in egg production and three weeks later for the investigation of Mycoplasma synoviae (MS), M. galliseptic

5. Coronavírus em codornas: ocorrência, diversidade molecular e estudo do papel epidemiológico das codornas como reservatório para a bronquite infecciosa das galinhas / Coronavirus in quails: occurrence, molecular diversity and the role of quails as reservoir for avian infectious bronchitis virus
Este estudo teve como objetivo pesquisar a ocorrência e diversidade molecular de coronavírus aviários em codornas e galinhas criadas nas mesmas propriedades e determinar o papel epidemiológico das codornas na bronquite infecciosa das galinhas (BIG). Para isso, foram coletados em granjas localizadas no estado de São Paulo e Espírito Santo pools de apare

6. A ÁGUA DE COCO EM PÓ (ACP) COMO DILUENTE BASE PARA VACINAS VIVAS AVIÁRIAS / WATER COCONUT POWDER (ACP) THINNER AS BASIS FOR VACCINE LIVE AVIAN
Diversas são as enfermidades virais que causam prejuízos econômicos e zootécnicos para a indústria avícola, entre elas destacam-se a bronquite infecciosa das galinhas (BI) e a doença de Newcastle (DN). Estas têm como uma das formas de controle as vacinações, que requerem critérios cada vez mais aperfeiçoados para a sua elaboração e execução a

8. Infectious bronchitis in Brazilian chickens: current data and observations of field service personnel
The infectious bronchitis virus (IBV) was detected for the first time in Brazil by Hipólito in 1957 in chickens sold life in the municipal market of Belo Horizonte, MG, when commercial poultry production was just starting in that country. The Massachusetts (Mass) serotype was identified. However, the clinical disease was only observed in 1975, when poultry

9. Avian infectious bronchitis virus in Brazil: a highly complex virus meets a highly susceptible host population
Infectious bronchitis (IB) is a highly aggressive disease for poultry in terms of symptoms and economic losses, and the control of this disease is difficult if flocks are not protected against type-specific challenges by the Avian infectious bronchitis virus (IBV). This article summarizes data presented by the author at the Workshop on Infectious Bronchitis

10. Diagnosis of infectious bronchitis: an overview of concepts and tools
Infectious bronchitis (IB) casues multi-systemic infection in chickens with signs similar caused by other poultry pathogens and thus a high diagnostic accuracy can only be achieved by s series of laboratory assays. This article reviews in a brief way the traditional virus assays such as embryo innoculation, tracheal rings and virus neutralization assays for

11. Molecular epidemiology and evolution of avian infectious bronchitis virus
Mutation and recombination processes are involved in the genetic and phenotypic variations of RNA viruses, leading to the emergence of new variant strains, and give rise to virus population diversity to be modeled by the host, particularly by the immune system, as occurred with infectious bronchitis virus (IBV) in chickens. The consequence is a continuous em

12. Europe: history, current situation and control measures for infectious bronchitis
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 1970
