Simultaneous detection of porcine circovirus type 2, classical swine fever virus, porcine parvovirus and porcine reproductive and respiratory syndrome virus in pigs by multiplex polymerase chain reaction

[swine abstracts]

A multiplex polymerase chain reaction (PCR) was designed for the simultaneous detection of four viruses involved in reproductive and respiratory failure in pigs: porcine circovirus type 2 (PCV-2), porcine parvovirus (PPV), classical swine fever virus (CSFV) and porcine reproductive and respiratory syndrome virus (PRRSV).

Haptoglobin and C-reactive protein as biomarkers in the serum, saliva and meat juice of pigs experimentally infected with porcine reproductive and respiratory syndrome virus

[swine abstracts]

The correlations found suggest that the measurement of Hp and CRP in saliva and meat juice could serve as complementary, or possibly alternative, biomarkers of pig herd-health.

Assessment of vitamin E levels, selenium levels and presence of viral pathogens as the etiology of mulberry heart disease

[swine abstracts]

The objective of this study was to determine a possible relationship between Mulberry Heart Disease (MHD) and the levels of vitamin E, selenium, and 13 other minerals, in heart and liver tissues, as well as to carry out PCR tests on heart tissues in order to determine the existence of a possible relationship between viral pathogens and MHD.

Inflammation-associated responses in piglets induced with post-weaning colibacillosis are influenced by dietary protein level

[swine abstracts]

Forty piglets (average body weight = 5.32 kg) were used to investigate the effect of dietary crude protein (CP) content on immunological responses following a challenge with enterotoxigenic Escherichia coli (ETEC) K88.
