PRRS Virus Evolution Slows

By Albert Rovira, DVM, University of Minnesota Veterinary Diagnostic Laboratory Porcine reproductive and respiratory syndrome (PRRS) virus remains a very important disease of swine in the United States. At the University of Minnesota Veterinary Diagnostic Laboratory, hundreds of samples are routinely tested for this virus by polymerase chain reaction (PCR) every month. This test can differentiate between the two main types of PRRS virus: the European type and the North American type. Both types have been described in the United States. read more

Get Ready for PRRS Season

2013-08-29 20:57:00| National Hog Farmer

Source: American Association of Swine Veterinarians Data from Steve Tousignant, DVM, at the National PRRS virus Incidence Project at the University of Minnesota, documents that annual epidemics of porcine reproductive and respiratory syndrome are repeatable. This is evidenced by a study that recorded the number of new PRRS virus cases in 370 sow herds across 14 unique production systems. For the past four years, the number of new cases on a weekly basis was expected to dramatically rise in mid-October (see graph). read more
