Extra-intestinal pathogenic E. coli (ExPEC), including avian pathogenic E. coli (APEC), pose a considerable threat to both human and animal health, with illness causing substantial economic loss. APEC strain χ7122 (O78∶K80∶H9), containing three large plasmids [pChi7122-1 (IncFIB/FIIA-FIC), pChi7122-2 (IncFII), and pChi7122-3 (IncI(2))]; and a small plasmid pChi7122-4 (ColE2-like), has been used...

Like many confused teenagers, the Asia-Pacifi c Economic Cooperation (APEC) has wrestled with its raison d’etre. Should it continue to set aspirational goals that make it feel good but that have little chance of success? What kind of relationship should it have to older and younger institutions? And can it develop a healthy routine that allows it to succeed, but which isn’t very glamorous? Sett...

The megacity of Beijing has experienced frequent severe fine particle pollution during the last decade. Although the sources and formation mechanisms of aerosol particles have been extensively investigated on the basis of ground measurements, real-time characterization of aerosol particle composition and sources above the urban canopy in Beijing is rare. In this study, we conducted real-time me...

Escherichia coli bacterium is common to many environments and there are over 150 different strains. Avian pathogenic E. coli (APEC) strains cause diseases in birds at various ages. The introduction of such strains to chicken respiratory tract causes invasive infections, collectively known as colibacillosis. It can cause extensive mortality in poultry flocks leading to great economic losses. Rec...

The regional growth of the goods and services trade has placed greater pressure on the ports of the Asia-Pacific Economic Cooperation (APEC) members, especially in the developing countries. The purpose of this study is to apply the generalized metafrontier Malmquist productivity index (gMMPI) to compare the port productivity of developed countries (DCs) and developing countries (LDCs) in APEC. ...
