Resumo: | Tracheal organ cultures (TOC) were prepared and used for evaluating four Brazilian isolates of infectious bronchitis virus (IBV). IBV field isolates and vaccine strains were titrated in TOC and results compared to those from chicken embrionated eggs. Serum neutralization (SN) employing IBV strain-specific serum was performed for evaluating relationships between isolates. Titration results of tests performed in TOC or eggs were in mutual agreement and were considered for validating the adapted TOC methodology as alternative for virological studies in our laboratory. Sera specific to M41 (Massachusetts) or A5968 (Connecticut) did neutralize their respective IBV strains only. Field strains 208 and 29-78 specific sera did neutralize Massachusetts serotype strains M41 and H120, but PM2 serum did only M41. Strain PM4 specific serum did not neutralize any of the reference IBV analyzed, including M41, A5968 and H120 and may indicate that the isolate is serologically different from the Massachusetts serotype, currently adopted for vaccine strains in Brazil.
