Abstract

Abstract: To assess the prevalence of adenoviruses in psittacine birds kept in Slovenia, 258 cloacal swabs were collected from different psittacine species and screened by a nested PCR with degenerate, consensus primers targeting the adenoviral DNA polymerase gene. Forty-two samples were found to be positive. By sequencing, 28 samples from 10 different parrot species were identified as the formerly described siadenovirus, psittacine adenovirus 2 (PsAdV-2). A second siadenovirus, a variant of PsAdV-5 (described earlier from Pacific parrotlet, sun parakeet, cockatiel and budgerigar) was found in seven budgerigars, two cockatiels and an amazon parrot species. A variant of Meyer's parrot adenovirus (aviadenovirus, proposed PsAdV-8) was identified in an African grey parrot and a cockatiel. Two novel atadenoviruses were revealed in cockatiel (PsAdV-9) and rose-ringed parakeet (PsAdV-10). These results support the earlier finding that many PsAdVs can cross the species barrier among psittacines, especially effectively in the case of PsAdV-2. Highlights: Two novel atadenoviruses were found in psittacine birds kept in Slovenia. A variant of Meyer's parrot adenovirus (an aviadenovirus) was identified. Two earlier described siadenoviruses were found in 13 psittacine species. Psittacine adenoviruses proved capable of crossing the species barrier.
