Porcine reproductive and respiratory syndrome virus.
Porcine reproductive and respiratory disease (PRRS) is an economically important disease around the globe; it has been estimated to cost the swine industry in USA approximately 560 million US dollars annually. It is well established that PRRS is caused by an enveloped, single-stranded positive-sense RNA virus known as porcine reproductive and respiratory syndrome virus (PRRSV). The inability to...
متن کاملThe effect of porcine parvovirus and porcine reproductive and respiratory syndrome virus on porcine reproductive performance.
From a worldwide perspective, porcine parvovirus (PPV) and porcine reproductive and respiratory syndrome virus (PRRSV) are the most common viral causes of porcine reproductive failure. A typical epidemic of PPV-induced reproductive failure is presented as an increased number of mummified fetuses and sometimes, entire litters are mummified. If infection with PPV is very early in gestation, the n...
متن کاملCell-Mediated Immunity in Porcine Reproductive and Respiratory Syndrome Virus
Porcine reproductive and respiratory syndrome virus (PRRSV) is a significant swine pathogen which exhibits considerable sequence diversity. In an attempt to identify highly conserved T-cell epitopes contained in proteins of this virus, we examined heptadecamer peptides spanning the sequence of the PRRSV nonstructural proteins 9, 10 and 11, all of them are highly conserved, for their ability to ...
متن کاملControl and elimination of porcine reproductive and respiratory syndrome virus.
Porcine reproductive and respiratory syndrome virus (PRRSv) can have a significant economic impact on swine herds due to reproductive failure, preweaning mortality and reduced performance in growing pigs. Control at the farm level is pursued through different management procedures (e.g. pig flow, gilt acclimation, vaccination). PRRSv is commonly eliminated from sow herds by a procedure called h...
متن کاملAnti-apoptosis in porcine respiratory and reproductive syndrome virus
Apoptosis and autophagy do not merely mediate cell death, but have the additional function of fighting against microbial invaders. If initiated at the proper time, apoptosis can limit viral infection by killing virus-infected cells. Autophagy (the “recycling factory” of the cell) can dismantle the pathogen. In response to these pressures, many viruses have co-evolved to hijack or manipulate the...
