Brazilian strain of bovine respiratory coronavirus is derived from dual enteric and respiratory tropism
Bovine coronavirus (BCoV) is a pathogen related to enteric and respiratory diseases in cattle worldwide. Enteric (BECoV) strains of BCoV are predominant in South America, and genetic investigations have been conducted to identify its relationship with isolates of respiratory origin (BRCoV). In this study, we used a BRCoV strain (BR-UEL11) derived from an outbreak of.. Read More»

VP6 gene diversity in Brazilian strains of porcine group C rotavirus
Group C rotavirus (RV-C) has been found in Brazilian pig herds; however, wild-type strains have not yet been characterized. We made a molecular analysis of a region of gene 5 in Brazilian RV-C strains. Stool samples from 11 piglets (diarrheic and with normal consistency) positive for the RV-C VP6 gene in an RT-PCR assay were sequenced. A 270-bp amplicon of nine sequ.. Read More»

Phylogenetic analyses of the hemagglutinin gene of wild-type strains of canine distemper virus in southern Brazil
This study examined the phylogenetic relationship of strains of canine distemper virus (CDV) collected from Paraná State, Brazil, based on the hemagglutinin gene. Urine samples were collected from 4 dogs from northern Paraná State that demonstrated clinical manifestations of canine distemper. The participation of CDV was initially confirmed by RT-PCR targeting the nucleocapsid pro.. Read More»

Isolation and molecular characterization of Leptospira borgpetersenii serovar Hardjo strain Hardjobovis in the urine of naturally infected cattle in Brazil
Most epidemiologic studies on bovine leptospirosis are based on serological tests that use antibodies against several serotypes, including the serovar Hardjo, which is widespread and considered to be the most adapted to bovine hosts. However, using only serological studies is not sufficient to identify and distinguish species of leptospires. The aim of this study was report the first isolation .. Read More»
