Abstract
Objective: To understand the prevalence, genetic diversity, and potential pathogenicity of adenoviruses present in pigeon and turtledove populations.
Methods: Nested PCR and Sanger sequencing methods were used to identify the genotype and percentage of various adenoviruses in the feces of pigeon (Columba) and turtledove (Streptopelia) populations. In Beijing, China, a total of 194 fresh feces samples from meat-use pigeons (C livia domestica), homing pigeons (C livia domestica), wild pigeons (C livia domestica), and turtledoves (S decaocto and S chinensis) were collected using noninvasive sampling collection techniques. Their partial DNA-dependent DNA polymerase gene sequences were obtained using nested PCR and double-ended Sanger sequencing, and their genotypes were then ascertained based on sequence alignment.
Results: A total of 6 genotypes of adenovirus were detected in pigeon and turtledove flocks, including pigeon adenovirus (PiAdV)-1, PiAdV-2A, PiAdV-3, PiAdV-4, PiAdV-5, and a novel adenovirus genotype (PiAdV-6). Among them, PiAdV-1 was found widespread in flocks of pigeons exhibiting extensive presentations of hepatic necrosis. Highly conserved PiAdV-4 and PiAdV-5 were found to be nonpathogenic and extensively distributed in all pigeon and turtledove groups.
Conclusions: These findings imply the presence of diverse PiAdVs in pigeon and turtledove flocks, and the wild pigeons and wild turtledove birds are potentially serving as natural sources of these viruses.
Clinical relevance: This study provides supportive evidence of the pathogenicity of different genotypes of adenovirus in pigeon flocks and also implies that stopping the transmission of the virus brought by wild pigeons and turtledoves may be important for the prevention of diseases associated with PiAdVs.
期刊介绍：
The American Journal of Veterinary Research supports the collaborative exchange of information between researchers and clinicians by publishing novel research findings that bridge the gulf between basic research and clinical practice or that help to translate laboratory research and preclinical studies to the development of clinical trials and clinical practice. The journal welcomes submission of high-quality original studies and review articles in a wide range of scientific fields, including anatomy, anesthesiology, animal welfare, behavior, epidemiology, genetics, heredity, infectious disease, molecular biology, oncology, pharmacology, pathogenic mechanisms, physiology, surgery, theriogenology, toxicology, and vaccinology. Species of interest include production animals, companion animals, equids, exotic animals, birds, reptiles, and wild and marine animals. Reports of laboratory animal studies and studies involving the use of animals as experimental models of human diseases are considered only when the study results are of demonstrable benefit to the species used in the research or to another species of veterinary interest. Other fields of interest or animals species are not necessarily excluded from consideration, but such reports must focus on novel research findings. Submitted papers must make an original and substantial contribution to the veterinary medicine knowledge base; preliminary studies are not appropriate.
