Does detecting PPV2 in lungs mean it causes respiratory or reproductive disease?
PPV2 was common in lungs from Colombian pigs, but coinfections predominated and direct localization in lesions was uncommon, so detection did not establish causation.

In this experimental model, DNA from inactivated M. hyopneumoniae did not persist at detectable levels, unlike viable organisms.
In mixtures containing modified-live vaccine and wild-type PRRSV, ORF5 Sanger sequencing primarily represented the dominant viral population and could mask a minority strain.
Exhaust-air sampling detected the onset of PRRSV circulation at the same sampling event as oral fluids in three barns, but it was less sensitive for later monitoring.
Experimentally infected pigs moved less, suggesting that automated movement monitoring may complement conventional measures of M. hyopneumoniae infection.
An mRNA-targeting PCR may better reflect M. hyopneumoniae viability than conventional DNA PCR, particularly near the end of elimination programs.
