Abstract
The present study reports the occurrence of rotavirus A (RVA), rotavirus D (RVD), rotavirus F (RVF), rotavirus G (RVG), and picobirnavirus (PBV) in fecal specimens of wild (n = 22), and exotic birds (n = 1) from different cities of Pará state. These animals were hospitalized at Veterinary Hospital of the Federal University of Pará, Brazil, in a period from January 2018 to June 2019. The animals exhibited different clinical signs, such as diarrhea, malnutrition, dehydration, and fractures. The results showed 39.1% (9/23) of positivity for RVA by RT-qPCR. Among these, one sample (1/9) for the NSP3 gene of T2 genotype was characterized. About 88.9% (8/9) for the VP7 gene belonging to G1, G3 equine like and G6 genotypes, and 55.5% (5/9) for the VP4 gene of P[2] genotype were obtained. In the current study, approximately 4.5% of the samples (1/23) revealed coinfection for the RVA, RVD and RVF groups. Furthermore, picobirnavirus (PBV) was detected in one of the 23 samples tested, and was classified in the Genogroup I. The findings represent the first report of RVA, RVD, RVF, RVG, and PBV genotypes in wild birds in Brazil, and due to wide distribution it can implies potential impacts of RVs, and PBVs on avian health, and other animals contributing to construction of new knowledge, and care perspectives. The anthropic action in the Amazon region directly influences the relationship among pathogens, and animal hosts. This kind of action could move different species of animals from their natural habitat to urban or rural areas, which can lead to the dispersion of different etiological agents such rotavirus and picobirnavirus, showing their zoonotic potential, and increasing their genetic diversity. This study detected the circulation of rotavirus in 9/23 samples of wild, and exotic avian, and 1/23 for picobirnavirus from different cities of Pará state, Brazil. We report the first occurrence of rotavirus A, D, F, G, and Genogroup I of picobirnavirus in wild, exotic birds in Brazil, and worldwide. Our data correlated the pathogens with cities, and symptoms. The data emphasize the scarce of epidemiological monitoring of these pathogens, and the importance of epidemiological studies to obtain the ecology, and evolution of rotavirus, and picobirnavirus in animals population as well as the negative impacts in animal health.Keywords
