Vaccination of dams increases antibody titer and improves growth parameters in finisher pigs subclinically infected with porcine circovirus type 2.

Porcine circovirus type 2 (PCV2) is the obligate infectious agent in postweaning multisystemic wasting syndrome (PMWS) of pigs. To control PMWS, we vaccinated dams at 4 and 2 weeks before pregnancy and again in the 12th week of gestation with an inactivated PCV2 vaccine (Circovac). Two producer farms run under the control of Swiss Swine Health Organization were selected for the experiment.

A new emerging genotype subgroup within PCV-2b dominates the PMWS epizooty in Switzerland.

Postweaning multisystemic wasting syndrome (PMWS) is among the most important emerging pig diseases worldwide. Initially, the insidious nature of the disease made it difficult to pinpoint the pathogen. The presence of porcine circovirus type 2 (PCV2) in all PMWS diseased animals led to its acceptance, possibly together with an unknown factor, as the causative agent for PMWS.

Glucocorticosteroid-induced spinal osteoporosis: scientific update on pathophysiology and treatment.

Glucocorticosteroid-induced spinal osteoporosis (GIOP) is the most frequent of all secondary types of osteoporosis. The understanding of the pathophysiology of glucocorticoid (GC) induced bone loss is of crucial importance for appropriate treatment and prevention of debilitating fractures that occur predominantly in the spine. GIOP results from depressed bone formation due to lower activity and higher death rate of osteoblasts on the one hand, and from increase bone resorption due to prolonged lifespan of osteoclasts on the other.

PMWS: an emerging disease identified in archived porcine tissues.

Postweaning multisystemic wasting syndrome (PMWS) is a disease caused by porcine circovirus type 2 (PCV-2). The disease was present as early as 1986 in Spain, 1989 in Japan and 1993 in Thailand. In view of this, we considered it possible that the disease may also have been present in Switzerland prior to its first description in 2001.

Porcine circovirus as a possible cause of postweaning wasting in pigs in Switzerland.

Postweaning wasting is a major worldwide problem in pig production, particularly with respect to the disease termed postweaning multisystemic wasting syndrome (PMWS). In addition to wasting, PMWS symptoms include respiratory distress, diarrhoea, pallor and occasional cases of jaundice. The causative agent is porcine circovirus type 2 (PCV-2).
