PRRS Biosecurity
Trailers contaminated with PRRSV can serve as a source of infection for naïve pigs. Therefore, sanitation for livestock trailers and transport vehicles is considered a high priority when it comes to biosecurity practices.

There are consistent strains of Streptococcus suis usually types 1 and 2 across Europe but the other strains vary from country to country.
Production factors associated with coughing and pneumonia in pigs
In the first of this series of articles on respiratory disease in pigs, the causes of coughing were reviewed. This second article reviews the production factors that are associated with respiratory disease.
Etiology: porcine circovirus type 2 (PCV2)... where is "agent X"?
Porcine circovirus type 2 is a viral agent with a relatively simple structural organization of which there are two distinct genotypes (1 and 2), it is not clear if they have similar virulence. Since some years ago there has been a hypothesis developing that there exists an “agent X” that would play a role as a trigger factor of the disease in 100% of cases.
What causes coughing in pigs?
Any factor that irritates or inflames the respiratory system will elicit the physiological response of either sneezing or coughing or both. Although alarming and indicative of disease, coughing is at least a sign that normal physiological responses are taking place and should not in isolation be necessarily seen as a bad thing. We may have sudden or generalized outbreaks of coughing as well as a constant coughing in pig groups. There are infectious pathogenic agents that are normally associated with coughing or laboured breathing in pigs such as Actinobacillus, Bordetella, Haemophilus, Pasteurella Streptococcus, Mycoplasma, SIV, PRRSV or PCV2.
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.
