Sa. Gilbert et al., TYPING OF PORCINE REPRODUCTIVE AND RESPIRATORY SYNDROME VIRUSES BY A MULTIPLEX PCR ASSAY, Journal of clinical microbiology, 35(1), 1997, pp. 264-267
A rapid multiplex PCR assay was developed to distinguish between North
American and European genotypes of porcine reproductive and respirato
ry syndrome (PRRS) virus after a portion of the polymerase gene (open
reading frame 1b) was sequenced for two North American PRRS virus stra
ins. DNA products with unique sizes characteristic of each genotype we
re obtained.
