Patologia cardiaca e agenti patogenici in feti suini abortiti [Heart disease and pathogens in aborted pig fetuses].
Società Italiana di Patologia ed Allevamento dei Suini - Proceedings, 2006, 161-168
A total of 609 aborted, stillborn and weak piglets originating from 132 Italian herds which had experienced reproduction outbreaks in 2003, 2004 and 2005, were subjected to bacteriological, virological and serological investigations. In addition, heart samples were examined for histological lesions. The main pathogens involved in such reproductive failures were Porcine circovirus type 2 (PCV2), Porcine Reproductive and Respiratory Syndrome Virus (PPRSV), Streptococcus spp and Escherichia coli. The presence of pathogenic agents was found correlated to that of heart microscopic lesions of myocarditis, endocarditis and epicarditis. However, several fetuses with cardiac lesions resulted negative to all investigated pathogens and conversely, some fetuses found positive for at least one pathogen resulted without any cardiac lesions. PCV2 was detected by PCR in 30% of the fetuses with or without cardiac lesions.
