Figure 4. Detection of avian bornavirus (ABV) RNA in different tissues from cockatiels that had been intracerebrally or intravenously inoculated with ABV and from a noninoculated sentinel bird. The geometric mean cycle thresholds (Ct) are shown with their respective standard deviations. Ct >36.0 is considered negative. Low Ct, implying high amounts of ABV RNA, was detected in neuronal and gastrointestinal tissue.
