13. 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

14. 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

15. 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

16. Etiology and immunology of infectious bronchitis virus
Infectious bronchitis virus (IBV) of chickens is currently one of the main diseases associated with respiratory syndrome in domestic poultry, as well as with losses related to egg production. The etiological agent is a coronavirus, which presents structural differences in the field, mainly in the S1 spike protein. The immune response against this virus is co

17. 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

18. Bronquite infecciosa das galinhas: conhecimentos atuais, cepas e vacinas no Brasil
A bronquite infecciosa das galinhas (IB) é uma doença viral aguda e altamente contagiosa que provoca grandes perdas econômicas à indústria avícola em todo o mundo. Considerando que surtos têm ocorrido no Brasil com emergência de novas variantes de IBV, desafiando as estratégias de vacinação atuais, este trabalho objetiva revisar os conhecimentos s

19. Epididymal lithiasis in Gallus gallus domesticus
A study on the occurrence of epididymal lithiasis (EL) in Gallus gallus domesticus of different breeds and from different geographical regions of Brazil was carried out. Forty breeding roosters were collected in the states Santa Catarina, São Paulo, Minas Gerais, Espírito Santo and Goiás, representing two specific pathogen free Leghorn lines (SPF), one co

21. Anticorpos contra vírus em galinhas de terreiro do Estado do Rio Grande do Sul, Brasil
No Brasil, a população de aves conhecida como galinhas de terreiro encontra-se fora do sistema de biosseguridade aplicada às criações comerciais. Para investigar a presença de anticorpos contra alguns vírus específicos nesta população, foram coletadas amostras de sangue de 867 aves não-vacinadas em 60 propriedades de 22 municípios do Estado do Ri

22. ANTIBODIES TO SPECIFIC VIRUS IN BACKYARD POULTRY AND CRACIDS, MICROBIOTA AND SUSCEPTIBILITY BACTERIAL IN CRACÍDS CAPTIVE FROM THE RIO GRANDE DO SUL STATE, BRAZIL / ANTICORPOS CONTRA VÍRUS DE AVES EM GALINHAS DE TERREIRO E CRACÍDEOS. IDENTIFICAÇÃO E SUSCEPTIBILIDADE A ANTIMICROBIANOS DA MICROBIOTA DE CRACÍDEOS CATIVOS NO RS, BRASIL.
A avicultura é uma das principais atividades econômicas do Brasil, que ocupa posição de destaque entre os exportadores de frango e subprodutos. O conhecimento da epidemiologia de patógenos que podem gerar prejuízos a essa atividade é essencial para o controle das enfermidades infecciosas. Este controle é realizado em larga escala em galinhas e perus

23. Interference of infectious bursal disease virus on antibody production against Newcastle disease and infectious bronchitis virus
This work has the objective of verifying the interference of infectious bursal disease virus in the antibody production against Newcastle disease virus and infectious bronchitis virus. The experiment was carried out with 640 day-old-chicks from a 42 weeks old hen flock. The birds were separated into eight experimental groups (n=80/group) and were submitted t

24. 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 infect
