Biosecurity measures for visitors should be implemented in all farms without exception, and hand washing with soap and subsequent disinfection should be compulsory in those farms where showering is not.

How can we tell whether a transport vehicle is clean by just taking a glimpse?

The great genetic diversity of East European strains has practical implications, the sensitivity of some of the diagnostic PCR methods can be compromised and the efficacy of the current PRRSV vaccines against the East European genetic variants still needs to be elucidated.

Enric Marco tells us that of late, it is relatively common to see fattening pigs in their final phase exhibiting respiratory symptoms that respond poorly to antibiotic treatments. In these cases, we usually think of PRRS virus; however raising the possibility of a mixed viral infection is less frequent...

A definitive diagnostic evaluation of PRRS with respect to clinical disease requires that serological information be interpreted in combination with results from other virus assays.

PRRSV favours the appearance of secondary infections like the one caused by S. suis  due to the impairment of the alveolar macrophages cleaning functions.

Surrounding holdings with high hedge fences reduces the risk of airborne transmission.

PCR is expensive relative to other diagnostic methods.It should be kept in mind that a positive result on PCR indicates the presence of viral RNA and does not necessarily indicate the presence of infectious PRRSV.

PRRSV does not favour infection by H. parasuis by reducing the population of alveolar macrophages, but by reducing their ability to inactivate the bacteria.
