Özet

Introduction and Aim: Chicken anemia virus (CIAV) causes aplastic anemia, lymphoid tissue atrophy, and immunosuppression, particularly in young chickens, resulting in economic losses in poultry production. Although extensively studied in commercial poultry, its presence and epidemiological significance in wild birds remain poorly understood. This study aimed to detect CIAV DNA in wild birds and phylogenetically compare the detected sequences with reference CIAV sequences from domestic and wild birds.

Materials and Methods: Oral and cloacal swabs from 100 wild birds representing 18 species admitted to the Wildlife Rehabilitation Center in Erzurum were examined. Following nucleic acid extraction, conventional PCR targeting a 298-bp region of the CIAV VP2 gene was performed. Positive products were sequenced, compared with GenBank reference sequences, and phylogenetically analyzed.

Results: CIAV DNA was detected in 10/100 birds (10%): four white storks (Ciconia ciconia) and one each of rock pigeon (Columba livia), western jackdaw (Corvus monedula), common buzzard (Buteo buteo), common kestrel (Falco tinnunculus), long-legged buzzard (Buteo rufinus), and European nightjar (Caprimulgus europaeus). Sequencing confirmed CIAV detection. Study sequences clustered with reference CIAV strains, and some were closely related to strains from domestic poultry in Türkiye (Figure 1).

Conclusion: This study reports the first detection of CIAV DNA in different wild bird species in Türkiye. Molecular and phylogenetic findings suggest that wild birds may contribute to CIAV ecology and circulation among poultry populations. Further epidemiological studies are needed to clarify their roles in virus persistence and transmission to domestic poultry.
