which would fit with a picture of a virus much like that of the novel coronavirus that emerged in the middle East last year Â that can cause severe disease.

Deadly pig virus slips through US bordersthe pathogen, a type of coronavirus called porcine epidemic diarrhoea virus (PEDV),

Coronavirus clues Scientists have an early lead in the search for animal sources of the Middle east respiratory syndrome coronavirus (MERS-Cov),

and has many similarities with transmissible gastroenteritis virus of swine said Meng who is a faculty member in the Department of Biomedical sciences and Pathobiology.

which belongs to the coronavirus family has caused economic and public health concerns in the United states. The ongoing outbreaks of Middle east respiratory syndrome coronavirus in humans from countries in

or near the Arabian peninsula and the historical deadly nature of the 2002 outbreaks of severe acute respiratory syndrome coronavirus create further anxiety about the emergency of PEDV in the United states due to the lack of scientific information about the origin

and evolution of this emerging coronavirus wrote Dr. Yao-Wei Huang the first author of the paper

and a former research assistant professor at the veterinary college who is now a professor at Zhejiang University

They did however come across additional evidence that the U s. strains share several genetic features with a bat coronavirus--findings which point to an evolutionary origin from bats and the potential for cross-species transmission.

#How deadly MERS virus enters human cellscornell University researchers have uncovered details of how the deadly Middle east respiratory syndrome coronavirus (MERS-Cov) enters host cells and offer possible new avenues

Coronaviruses have a spike protein that is activated by a protease and mediates membrane fusion and entry into a host cell.

This is the first characterization of a natural coronavirus with a spike protein containing two furin cleavage sites said Millet the paper's first author.

This study shows how flexible coronaviruses are in terms of cleavage activation strategies said Millet. They are extremely adaptable.

of which have entered the United states for the first time--porcine epidemic diarrhea virus and delta coronavirus. Swine specialists and molecular diagnosticians at the Kansas State Veterinary Diagnostic Laboratory have developed tests to detect which virus is infecting the pigs.
