Can Legionella bacteria be measured?

This section describes the measurement of Legionella bacteria. Infection of Legionella bacteria sometimes becomes a problem in bathing facilities. Periodic inspection is required but it takes almost one week.
If it can be inspected quickly on-site, it may help to take countermeasures quickly.
We checked if it can be measured using a mobile PCR device.
