3.1 PCR detection and prevalence analysis of PiCV infection in
Chinese racing pigeons
In this study, PiCV was detected in samples from both sicked and healthy
racing pigeons. The results indicated that the positive rates of PiCV
were 19.3% (120/622) at the sample level. Among the samples, 14 out of
51 sick pigeons (positive rate, 27.4%) and 106 out of 571 healthy
pigeons (positive rate, 18.6%) were identified to be PiCV positive,
respectively. In this study, 23 out of 39 racing pigeon clubs were
positive for PiCV (positive rate, 59.0%) (Table 1). Detailed
information for 120 PiCV positive samples from racing pigeons in China
is shown in Table 1.
