ABSTRACT

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 sobre IB e IBV, a sua distribuição, as cepas e as vacinas utilizadas no Brasil.
