Encephalomyocarditis virus (EMCV) infections can cause losses in pig farms all over the world. Rapid, sensitive and unequivocal detection of this virus is therefore essential for the diagnosis and control of the disease. An RT-PCR assay was developed, optimized and evaluated for encephalomyocarditis virus detection in organ based on a pair of primers that amplifies a 165 bp DNA fragment from a highly conserved nucleotide region of the viral 3D glycoprotein. PCR products of the expected size were obtained from Cuban EMCV 744/03 strain. Non-specific reactions were not observed when other porcine RNA genome viruses and uninfected cells were used. The analytical sensitivity of the test was estimated to be 2 TCID50/50 mL. The analysis of tissue homogenate... |

Aujeszky's disease, also known as pseudorabies causes severe economic losses in swine industry and affects the pig husbandry all over the world. The conventional diagnostic procedure is time-consuming and false-negative results may occur in submissions from latently infected animals. The development, optimization and evaluation of a polymerase chain reaction (PCR) assay are presented for the diagnosis of pseudorabies infection. This assay was based on the amplification of a highly conserved viral gD gene fragment. PCR products of the expected size were obtained from PRV strains. Non-specific reactions were not observed when a related herpesvirus, other porcine DNA genome viruses and uninfected cells were used to assess PCR. The analytical sensitivity of... |
