Neospora caninum has been detected in several wild mammalian species, i.e., deer, coyotes, dingoes, and foxes. Farm-bred foxes were rarely reported to be affected by the parasite. In this study, we detected for the first time the infection of N.caninum in farm-bred young blue foxes (Alopex lagopus) in China. Neospora-like tissue cysts were observed in(More)
Porcine circovirus type 2 (PCV2) is continuously evolving through point mutation and genome recombination. In the present study, genetic affiliations of 40 PCV2 strains were determined by amplification, sequencing and phylogenetic analyses during the nationwide molecular epidemiology investigation from 2009 to 2010 in mainland China. The results revealed(More)
Here, we report a novel porcine circovirus type 2a (PCV2a) strain with 11 nucleotides (nt) inserted in the origin of genome replication (Ori). This is the first report of a PCV2a strain with nucleotide insertion in Ori. Our study will help further epidemiological studies and extend our knowledge of evolutionary characteristics of PCV2.
Porcine reproductive and respiratory syndrome virus (PRRSV) non-structural protein 7 (Nsp7) plays an important role in the induction of host humoral immune response and could serve as an ideal antigen for serological genotyping assay for PRRSV based on the significant difference in immunoreactivities of North American (NA) and European (EU) PRRSV Nsp7.
