Serological Surveillance and Risk Factor Analysis for Parrot Bornavirus in Taiwan

Figure 2

Summary of serum samples used in this study. (a) Clinical serum samples collected from various cities in Taiwan. Data for seropositive, seronegative, and seropositive rates are presented. (b) The frequencies of seropositive (n = 95) and seronegative (n = 275) samples and the identified PaBV genotypes (PaBV-2/4, n = 87, and PaBV-5, n = 8) are shown. (c) The frequency of serum samples (n = 370) from male (n = 187) and female (n = 175) parrots was analyzed to determine the effect of sex. Seven samples without sex information were excluded from Fisher’s exact test. (d) The frequency of serum samples from juvenile (<one year old, n = 101) and adult (>one year old, n = 261) parrots was evaluated using Fisher’s exact test. (e) The frequency of serum samples from multibird and single-bird households was assessed using Fisher’s exact test. The odds ratio (OR) was calculated and statistical significance was determined using a p-value of less than 0.05.
