“…Fecal samples included in this study were from a collection housed at the Laboratory of Respiratory, Enteric and Ocular Viruses (LAVIREO) at the Federal University of Rio de Janeiro. Samples in this collection were obtained from asymptomatic chickens in the southeastern Brazilian cities of São José do Vale do Rio Preto (May 2013), and Bom Jardim (October 2018), in the state of Rio de Janeiro, and Marechal Floriano (October 2018), in the state of Espírito Santo ( Figure 1 ), and were analyzed previously for RVF and RVG by RT-PCR [ 43 ].…”

Avian rotaviruses (RVs) are important etiologic agents of gastroenteritis in birds. In general, avian RVs are understudied; consequently, there is a paucity of information regarding these viruses. Therefore, the characterization of these viral species is highly relevant because more robust information on genetic, epidemiologic, and evolutionary characteristics can clarify the importance of these infections, and inform efficient prevention and control measures. In this study, we describe partial genome characterizations of two avian RV species, RVF and RVG, detected in asymptomatic poultry flocks in Brazil. Complete or partial sequences of at least one of the genomic segments encoding VP1, VP2, VP4, VP6, VP7, NSP1, NSP4, NSP4, or NSP5 of 23 RVF and 3 RVG strains were obtained, and demonstrated that multiple variants of both RVF and RVG circulate among Brazilian poultry. In this study, new and important information regarding the genomic characteristics of RVF and RVG is described. In addition, the circulation of these viruses in the study region and the genetic variability of the strains detected are demonstrated. Thus, the data generated in this work should help in understanding the genetics and ecology of these viruses. Nonetheless, the availability of a greater number of sequences is necessary to advance the understanding of the evolution and zoonotic potential of these viruses.
