Five groups of eight fattening pigs were vaccinated and then infected with Aujeszky's disease virus. Viral excretion was evaluated by two means: deep nasal swabbing and air sampling. It appeared that infectious airborne virus could be recovered from day 1 to day 6 after infection in the isolated units where control animals were raised. In vaccinated animals, airborne particles were also detected but the amount and duration varied in relation to their immune status at the day of virulent challenge: viral excretion was significantly lower in pigs presenting a high antibody level (1/16 to 1/64) just before infection. Results obtained with nasal swabs and with air samples were closely related. Despite its low sensitivity, the air sampling procedure could be considered as an efficient tool for reflecting infectious viral pressure in a confined atmosphere.

D004197 Disease Reservoirs Animate or inanimate sources which normally harbor disease-causing organisms and thus serve as potential sources of disease outbreaks. Reservoirs are distinguished from vectors (DISEASE VECTORS) and carriers, which are agents of disease transmission rather than continuing sources of potential disease outbreaks. Humans may serve both as disease reservoirs and carriers.
