DYNAMICS OF PORCINE CIRCOVIRUS TYPE 2 INFECTION AND EXCRETION IN PIGS FROM POSTWEANING MULTISYSTEMIC WASTING SYNDROME AFFECTED FARMS FROM SPAIN AND DENMARK

摘要

Serological and non-quantitative DNA detection techniques (PCR) have been widely used to monitor porcine circovirus type 2 (PCV2) infection dynamics (1,2). In spite of available epidemiological information, very few data on PCV2 load dynamics of Postweaning multisystemic wasting syndrome (PMWS) affected and non-affected pigs in PMWS affected farms are available. The present longitudinal study describes the evolution of PCV2 infection and excretion in pathologically characterized pigs from PMWS affected farms from two different countries, namely Denmark and Spain.
