Since late 2011, cases of suspected canine pseudorabies have increased in north China with the outbreak of swine pseudorabies in the same area, but the pathogenesis of canine Pseudorabies virus (PRV) infections in China is poorly understood. In this study, we investigated the pathogenesis of canine pseudorabies. The pathological changes in 13 dogs that died(More)
Atmospheric particulate matter (PM) from multinatural and anthropogenic sources poses serious risk to human health and contaminates soil and water resources as it settles back to ground environment and ecosystem. In this study, dust deposition flux (DDF), pollution load index (PLI) of heavy metals, enrichment factor (EF), and settling flux (SF) of eighteen(More)
A transposon mutant library of B. melitensis NI including 32,640 transposon mutants was established. By sequencing the transposon insertion sites, 10,832 mutants were successfully defined for their insertion sites. Analysis of the mutants with defined transposon insertion sites (DTIS) indicated that the insertions were well spread through the two genomes.(More)
This study aimed to investigate concentrations and mobility of selected metals (As, Cd, Cr, Co, Cu, Mn, Ni, Pb and Zn) contained in the bulk atmospheric deposition of Beijing, China, between March 2007 and February 2008, and to evaluate the metal deposition fluxes. Beijing endured heavy atmospheric deposited metal pollution with a deposition flux of 149.28(More)
