| 摘要 |
The invention relates to a method of detecting the presence or absence of a target microbe in a liquid sample, the method comprising: providing a powdered medium having one or more nutrient indicators and ingredients to support the growth of the target microbe, the one or more nutrient indicators being operable to alter a detectable characteristic in a medium/sample mixture when metabolized by the target microbes so as to confirm the presence or absence of target microbes in the sample, wherein the medium lacks a gelling agent and the medium is free of target microbes before mixing with a sample; providing a liquid sample; combining the powdered medium and the liquid sample to form a medium/sample mixture; and observing the mixture for the presence or absence of a detectable characteristic wherein the presence of the detectable characteristic results from a target microbe metabolizing a nutrient-indicator.
