Epidemiology and genotypic diversity of canine circovirus identified in pet dogs in Harbin, China.

Canine circovirus (CanineCV) is a single-stranded DNA virus that circulates in dogs and wild carnivores around the world. It has been suggested to be associated with diseases of respiratory and gastrointestinal systems, though its pathogenic potential remains unclear. Currently, CanineCV is divided into six genotypes (genotype 1-6), and genotypes 2, 3, and 4 have been described in China.

[Cloning and Expression of Tibetan Sheep-origin Echinococcus granulosus Antigen B Gene and Protein Identification Using Immunological Method].

Objective: To clone and express the Tibetan Sheep-origin Echinococcus granulosus Antigen B8/2 Gene, and immunologically identify the encoded protein.

Methods: The cDNA of EgAgB8/2 gene was amplified by RT-PCR. The prokaryotic expression vector pET-EgAgB8/2 was constructed and transformed into E.
