Clinical and pathological responses of pigs from two genetically diverse commercial lines to porcine reproductive and respiratory syndrome virus infection.
The response to infection from porcine reproductive and respiratory syndrome virus (PRRSV) for 2 genetically diverse commercial pig lines was investigated. Seventy-two pigs from each line, aged 6 wk, were challenged with PRRSV VR-2385, and 66 litter-mates served as control. The clinical response to infection was monitored throughout the study and pigs were necropsied at 10 or 21 d postinfection...
متن کاملEvaluation of airborne shedding of modified-live porcine reproductive and respiratory syndrome virus from growing pigs
Introduction Porcine reproductive and respiratory syndrome (PRRS) costs the US pork industry $1.8 million per day.1 Swine practitioners have been successful eliminating PRRS virus (PRRSv) from breeding herds by implementing herd closure-homogenization protocols.2 Implementation of these protocols has resulted in a source of PRRSv PCR-negative weaned pigs to be placed in growing facilities. A la...
متن کاملAn investigation of susceptibility to porcine reproductive and respiratory syndrome virus between two genetically diverse commercial lines of pigs.
The objective of this study was to determine whether host genetics play a role in susceptibility to the respiratory disease in growing pigs caused by the porcine reproductive and respiratory syndrome virus (PRRSV). Based on a previous study, 2 genetically diverse commercial lines of pigs that also were divergent in the susceptibility of monocyte-derived macrophages to PRRSV infection in vitro w...
متن کاملBiological responses to porcine respiratory and reproductive syndrome virus in pigs of two genetic populations.
One hundred pigs from the NE Index Line (NEI) and 100 Hampshire-Duroc cross pigs (HD) were inoculated intranasally with porcine respiratory and reproductive syndrome virus (PRRSV 97-7895 strain) at 26 d of age to determine whether genetic variation in response to PRRSV exists. An uninfected littermate to each infected pig served as a control. Pigs were from 163 dams and 83 sires. Body weight an...
متن کاملPorcine 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...
