| data from 11 years of molecular typing infectious bronchitis virus field isolates. | in 1993, a new molecular typing method for infectious bronchitis virus (ibv) was introduced. this method uses reverse transcriptase-polymerase chain reaction (rt-pcr) and restriction fragment length polymorphism (rflp) analysis of the spike gene to obtain rflp patterns that correlate with serotype. using that test at the poultry diagnostic and research center (pdrc, university of georgia, athens, ga), we have identified a total of 1523 ibv isolates in the past 11 yr. the data were obtained from ... | 2005 | 16405010 |
