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. 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

3. 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

4. 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

5. 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

6. 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

7. 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

8. Molecular studies of the Brazilian infectious bronchitis virus isolates
Avian infectious bronchitis virus (IBV) isolates have been widely characterized by reverse transcription followed by polymerase chain reaction and DNA sequencing. In present study, these techniques were applied to three viral genomic regions comprising the complete and/or a partial S1 segment, S2 and nucleocapsid genes. DNA sequences from viral isolates obta

9. Vírus da bronquite infecciosa das galinhas (IBV): distribuição, diversidade molecular e genealogia a partir de amostras de múltiplos órgãos de diversos tipos de criação do plantel avícola brasileiro / Avian infectious bronchitis virus (IBV): distribution, molecular diversity and genealogy of multiple organs strains of different types of birds from Brazilian poultry
A bronquite infecciosa das galinhas (BIG) é uma doença altamente contagiosa causada por múltiplos genotipos/sorotipos do vírus da bronquite infecciosa das galinhas (IBV), um coronavirus do grupo 3. Embora classicamente associado ao trato respiratório, alguns tipos de IBV têm sido descritos com tropismo pelos rins e pelos tratos reprodutivos e entérico

10. Effects of methionine and arginine dietary levels on the immunity of broiler chickens submitted to immunological stimuli
The present study aimed at assessing the effects of methionine and arginine on the immune response of broiler chickens submitted to immunological stimuli. Three methionine concentrations (0.31, 0.51, and 0.66% from 1 to 21 days of age; 0.29, 0.49, and 0.64% from 22 to 42 days of age) and 2 arginine concentrations (1.33 and 1.83%; 1.14 and 1.64% for the same

11. Estudo epidemiológico de doenças infecciosas em anatídeos da Fundação Parque Zoológico de São Paulo / Epidemiological study of infectious diseases on waterfowls from Fundação Parque Zoológico de São Paulo
Waterfowls housed in ponds of zoos and parks are under constant risk of exposure to pathogens of migratory birds that visit these places every year. Some of them involving zoo animals and humans. The spread of particular diseases may also become a serious threat for domestic poultry. So, surveillance, focused in early detection of some diseases, can be an in
