【Abstract】 Porcine reproductive and respiratory syndrome(PRRS) is caused by PRRS virus,which has the ability to infect macrophages and to consist in the tissues of boars for at least several months.As a consequence,PRRS has been especially difficult to control under the usual conditions.Vaccination is only approach of designing a control strategy.In order to effectively control and eradication of PRRS,it is necessary to provide answer to a series of questions related to both persistence and dissemination of the virus within the adult swine population.It is especially important to research on PRRSV of the boar.The objective of this review is to summarize the knowledge available today regarding PRRSV infection in the boar,and to answer the main questions that the infection creates,especially those related to the epidemiological risk posed by the persistence and dissemination of the virus by different routes.更多还原
