The article focuses on the discovery by a group of scientists in the U.S. as of April 2012, of a genetic marker called a quantitative trait locus in pigs, that identifies whether or not a pig has reduced susceptibility to porcine reproductive and respiratory syndrome (PRRS). The scientists found the marker on swine chromosome four that is associated with resistance to PRRS virus infection. Research methodology is also examined.

    Between January 2012 and March 2012, the infection rates of porcine epidemic diarrhea virus (PEDV) increased substantially in vaccinated swine herds in many porcine farms in Gansu Province, China. The spike (S) glycoprotein is an important determinant for PEDV biological properties. To determine...
