Implication

Experimental trial shows PRV1 induces chronic tracheitis and is a primary respiratory pathogen in pigs, highlighting its impact on health and transmission.

Key Points

PRV1 is implicated as a primary respiratory pathogen in pigs, demonstrating significant pathogenicity in upper respiratory tract.
Nasal swabbing indicated PRV1 shedding peaked between DPI 4 and 7, confirming horizontal transmission among pigs.
Inoculated pigs demonstrated chronic, erosive tracheitis and some developed bronchointerstitial pneumonia by DPI 14.
The results underscore the health implications of PRV1 for porcine welfare, while SOV did not successfully infect the subjects.
