PRRS control
The presence of subpopulations of exposed and non-exposed sows in chronically PRRSV-infected breeding herds assists in the maintenance of virus circulation in the breeding herd over time.
PRRS: Diagnostic testing methods
This article will focus on selected antigen and antibody detection methods based on their application by practicing veterinarians to field cases in the US.
PRRS: Transmission via indirect routes (2/2)
Migratory waterfowl have been proposed as vectors of PRRSV spread between farms, due to their migratory nature and their tendency to nest on or near to swine farm lagoons
Current sanitary problems in the United States
The focus of swine production in the USA has changed over the last five years. Many businesses in the sector have made radical changes in management both from the reproductive and the sanitary point of view.

Diseases in Europe (1 of 2)
Overall, the disease situation in Europe is very similar although there are some countries that have a problem with certain diseases that others do not have
PRRS: Transmission via direct and indirect routes (1/2)
In this second part the direct routes (infected pigs and contaminated semen) and indirect routes (fomites and transportation vehicles) of PRRSV are tackled, as is the persistence of the virus because the persistence of the infection is a characteristic of PRRSV infections in pigs and plays a major role in the control and eradication of the disease.
PRRS: Etiology and clinical manifestation
Scott Dee, the prestigious American veterinarian who is known worldwide for his research on the PRRS virus, will be in charge of this section which is dedicated exclusively to the PRRS disease. Every month a new article will be published related to subjects such as etiology and clinical signs, transmission routes, diagnostic testing methods, biosecurity or control and eradication.
