Última Isolation in HRT-18 cells and molecular analysis of a BCoV strain from diarrheic feces of naturally infected calves BABT Stipp,Danilo Tancler; Barry,Aline Fernandes; Alfieri,Alice Fernandes; Bodnar,Lívia; Alfieri,Amauri Alcindo. Bovine coronavirus (BCoV) may cause acute diarrhea in newborn calves, leading to significant economic losses for cattle farmers. There are several diagnostic techniques used to detect BCoV in calf fecal samples, but virus isolation still has advantages for antigenic and genomic characterization. This study describes the isolation in HRT-18 cells and molecular characterization of Brazilian BCoV wild-type strains. Three fecal samples from diarrheic 30 day-old calves were inoculated in HRT-18 cell monolayers, which were then evaluated for HA titers and tested using semi-nested PCR followed by RFLP and sequencing. Two samples were successfully isolated and presented HA titers of 16 and 32 units per 25 mL. The results were confirmed using semi-nested PCR and...

Neonatal diarrhea is an important cause of economic losses for cattle farmers. The main viral etiologies of enteric diseases are group A rotaviruses (GARV) and the bovine coronavirus (BCoV). Although both viruses infect calves of the same age, the occurrence of mixed infections is still under studied. The present study describes the co-infection of BCoV and GARV in stool samples. Forty-four diarrheic fecal samples from calves up to 60 days old that had previously tested positive for GARV by SS-PAGE were analyzed using semi-nested PCR for BCoV. A product with 251 bp of the BCoV nucleoprotein gene was amplified in 15.9% (7/44) of the samples, demonstrating that co-infection is not an unusual event. These results reinforce the need for testing for both GARV... Tipo: Info:eu-repo/semantics/article Palavras-chave: Calf; Diarrhea; BCoV; Rotavirus; SN-PCR; Co-infection.
