Many different IBV vaccines -mostly against variants of the Massachusetts strain- have been developed internationally, and their efficacy in broilers and laying hens has been well studied.

Rev Bras Cienc Avic. Additional Massachusetts strain variants were serotyped for Israel, during the mid s [13, 45, 46] and other IBV variants were described in Korea during the mid s [47]. Samples were taken from paranasal sinuses, trachea and lungs for histopathological study, and trachea-lung pools were prepared from four individuals for virus isolation and molecular biology assays.

Preparation of antigens of and of vaccines for the virus of mystery disease, antigens and vaccines obtained for the prevention of this disease. In advanced stages of the respiratory infection there was also metaplasia of the cylindrical pseudostratified epithelium to flat cells, with submucosal engrossment Figures 2C and D. Another possible cause is the movement of flocks and the mixing of layer hen batches, which together propitiate coinfections by unrelated strains and thus, the occurrence of recombination events between separate IBV lineages.

Another important histopathological finding is the presence of hyperplastic acinotubular glands. They were fed a balanced diet, and their handling complied with current technical guidelines and regulations of the country, in force since the decade of the s [20].

Among the anatomopathological characteristics of mild cases of respiratory bromquitis are excessive mucus, which can even become sebaceous —especially in broilers— and pulmonary congestion and opacity, with engrossed air sac walls.

One prominent example of the latter case is that of avian infectious bronchitis virus IBVa gammacoronavirus belonging to the Coronaviridae family, in the order Nidovirales [3]. The main clinical symptoms exhibited by laying hens affected by this virus include serous conjunctivitis, infeccioda and, ultimately, asphyxia.
