A clone containing the complete genome of chicken anaemia virus (CAV) was used in hybridizations with DNA from various field isolates of CAV. CAV DNA from all field isolates was detected in a polymerase chain reaction with oligonucleotides derived from the sequence of the cloned CAV DNA as primers. By way of Southern blot analysis with 32P-labelled DNA probes derived from cloned CAV DNA, all field isolates were shown to contain DNA molecules of about 2.3 kb, i.e. the size of cloned CAV DNA. In a dot-blot assay it was demonstrated that non-radioactively-labelled cloned CAV DNA hybridized specifically to DNA from field isolates. The cloned CAV DNA is highly similar to the DNA of field isolates, as borne out by restriction-enzyme mapping. We conclude that our cloned CAV genome is representative for CAV in the field. The described PCR and hybridization techniques, may, therefore, be used for research and diagnosis of CAV infections. |
