The labelled DNA was used as a probe for detecting viral DNA in faecal samples of experimentally infected birds. Proteinase K treated, phenol extracted, alkali denatured samples exhibited strong signals as compared to proteinase K digested samples alone. The probe could detect up to 1.25 pg of viral DNA. However, it did not show any positive signal with another adenovirus, i.e., hydropericardium syndrome viral DNA indicating its specificity for egg drop syndrome virus (EDSV). </smarttagtype></smarttagtype></smarttagtype>
