Monitoring of Legionella should be carried out as part of a planned programme of maintenance on water systems or cooling waters.

It is beneficial to be able to demonstrate the presence of Legionella in aerosol droplets associated with suspected reservoirs of the bacterium.

International pbi has developed and produced a specific bioaerosol sampler for Legionella:
The "SAS-Legionella", is a portable, compact and battery operated instrument for use in the field.

The liquid collecting method "recirculating bioaerosol system" is a patented approach. Air and sterile collecting fluid flow together through a nozzle and are poured into a vessel with a coil. The liquid is circulated continuously to prolong the contact time between bioaerosol and collecting liquid.

The liquid is then analysed by traditional microbiology or PCR technique.

The Application Note "Legionella pneumophila quantification in bioaerosol" is available from International pbi and gives more details about Legionella detection.
