Identification of bovine and porcine rotavirus G types by PCR.
A new seminested PCR typing assay has been extended to identify the important veterinary rotavirus serotypes G5, G6, G10, and G11, as well as the rare human serotype G8. The specificity of the method was evaluated with 30 standard laboratory strains of the G1 to G6 and G8 to G11 types. Rotavirus strain types G6 and G8, not previously recognized in pigs, were identified in field specimens of por...
متن کاملPorcine Rotavirus Closely Related to Novel Group of Human Rotaviruses
We determined nucleotide sequences and inferred amino acid sequences of viral protein (VP) 4, VP6, VP7, and nonstructural protein 4 genes of a porcine rotavirus strain (SKA-1) from Japan. The strain was closely related to a novel group of human rotavirus strains (B219 and J19).
متن کاملMolecular typing of group A bovine rotavirus of calves in the provinces of Tehran, Alborz and Qazvin
BACKGROUND: Group A bovine rotavirus (BRV-A) is one of the most important causes of gastroenteritis and diarrhea in newborn calves. OBJECTIVES: Major types of BRV-A in Tehran, Alborz and Qazvin were detected in this study. METHODS: A total 125 fecal samples of calves showing clinical signs of diarrhea were collected from 26 industrial dairy farms located in the provinces of Tehran, Alborz and Q...
متن کاملDual infection of gnotobiotic calves with bovine strains of group A and porcine-like group C rotaviruses influences pathogenesis of the group C rotavirus.
There is serological evidence that bovine group C rotaviruses exist in the United States, but there are no reports of their isolation. Ninety fecal samples from calves with diarrhea, 81 samples from adult cows with diarrhea (winter dysentery), and 20 fecal samples from healthy adult cows were tested for group C rotaviruses by polyacrylamide gel electrophoresis, immune electron microscopy, and r...
متن کاملMultiplex PCR for detection and typing of porcine circoviruses.
Sets of oligonucleotide primers were designed according to the sequences of the open reading frames (ORFs) ORF1 and ORF2 of the prototype nonpathogenic PK-15 strain of porcine circovirus (PCV) type 1 (PCV-1). By the PCR performed with the various primer sets, genomic DNA or RNA from other bacterial or viral pathogens of the respiratory tracts of pigs could not be amplified. A positive amplifica...
