Concurrent circulation of PRRSV-US within swine herd in Poland.
Proceedings of the 4th International Symposium on Emerging and Re-emerging Pig Diseases, 2003, 67-68
Primarily, the genotypes of PRRSV (American or European), were linked to the initial geographic distribution from which they had taken their name. However, such perfect match is not valid anymore since both types have been detected where they were originally not present. In this report of PRRSV-US infection in a Polish swine herd, Ingelvac? PRRS modified live vaccine (Boehringer Ingelheim) is recognized as the source of the circulating virus.
