Abstract: Methods and systems for detecting the presence of a target microorganism in a liquid sample are provided. Methods comprise the steps of passing the liquid sample through a surface filter, placing the surface filter into contact with a culture device, incubating the culture device for a period of time and detecting the presence of a target microorganism. Methods may be used with an automated detection system.
