Freqüência do parvovírus suíno em fetos mumificados, abortados e natimortos detectado através da reação em cadeia pela polimerase (PCR)

Porcine parvovirus (PPV) is associated with reproductive failure and it has been found worldwide, including Brazil. Many diagnostic procedures are used for its detection, for example, immunofluorescence, HA, HI and PCR and this is an important technique because it is very specific and sensitive. In this work, the presence of PPV in fetuses from swine farms with reproductive problems was detected by PCR. All of 170 samples from aborted fetuses, mummies or stillborns were sampled by PCR with primers designed to VP2 region of PPV and c-myc (endogenous control). Only 142 samples (83,53%) were positive for c-myc and among them six samples (4,22%) were positive for PPV which were tested in HA. In this test, erythrocytes suspension 1% was used and three samples (50%) agglutinated but they presented low titer (4). For this work, porcine parvovirus was detected in the samples analyzed by PCR and HA. It is important to emphasize the use of endogenous control when material with elevated degree of autolysis is examined
