Abstract:
... In order to investigate the genetic diversity of porcine circovirus type 2 (PCV2), 284 clinical tissue samples were collected from different pig farms in central China from 2015 to 2017. A total of 162 tissue samples (162/284, 57.04%) were positive for PCV2 by PCR, and subsequently, the complete genome of 36 of these PCV2 samples was cloned and sequenced. The sequencing results showed that 37 comp ...

Abstract:
... Grapevine red blotch virus (GRBV) is an emerging virus of significant viticultural importance throughout North America. Here, we report the development of a simple protocol for point-of-use detection of GRBV. Extraction of nucleic acids is not required; instead, the whole intact plant can simply be pricked with a sterile pipette tip, which is then incubated in sterile distilled water to provide th ...

Bacteriophages offer a safe means for eliminating this pathogen. In the present study, we characterized two closely related Cronobacter-specific bacteriophages of the proposed genus “GAP227virus”. The phages De ...

However, no transcriptional regulator has been identified in any reovirus. Here, a non-structural protein, NS31, encoded by grass carp reovirus genomic segment S7 was characterized. The NS31 protein is predicted to contain a helix-turn-helix (HTH)-like domain an ...
