    • The presence or absence of a predetermined target microbe in a sample is determined by adding a testing medium to the sample, or vice versa. The testing medium provides a selective growth medium for the target microbe and includes a specific nutrient which only the target microbe can meta­bolize. This specific nutrient is modified by attaching a sample-altering moiety thereto, thereby converting the nutrient to a nutrient-indicator. The sample-altering moiety is activated to alter the sample only if the specific nutrient is metabolized by the target microbe. The sample-altering moiety can be a material which changes the color of the sample (visible or non-visible) or changes an electrical characteristic of the sample, or alters some other detectable characteristic of the sample. The testing media does not have to be kept sterile, and the testing procedure does not have to be performed in a sterile environment.
    • 通过向样品中加入测试培养基来确定样品中预定目标微生物的存在或不存在,反之亦然。 测试培养基为目标微生物提供选择性生长培养基,并且包括只有目标微生物可代谢的特定营养物质。 通过将样品改变部分附接到其上来改变该特定营养物,从而将营养物转化为营养指示剂。 只有当特定营养物质被目标微生物代谢时,样品改变部分被激活才能改变样品。 样品改变部分可以是改变样品的颜色(可见或不可见)或改变样品的电特性或改变样品的一些其它可检测特征的材料。 测试介质不必保持无菌状态,测试程序不必在无菌环境中进行。

    • The presence or absence of a predetermined target first generation environmental sourced microbe in an environmentally derived sample is determined by adding a testing medium to the sample, or vice versa. The testing medium provides a selective growth medium for the target microbe and includes a specific nutrient which only the target microbe can significantly metabolize and use for growth This specific nutrient is modified by attaching a sample-altering moiety thereto, thereby converting the nutrient to a nutrient-indicator. The sample-altering moiety is activated to alter the sample only if the specific nutrient is metabolized by the target microbe. The sample-altering moiety can be a material which changes the color of the sample (visable or non-visable) or changes an electrical characteristic of the sample, or alters some other detectable characteristic of the sample. The testing media does not have to be kept sterile, (but, obviously must be free of viable target microbes) and the test ire procedure does not have to be performed in a sterile environment. The medium also includes an accelerant which hastens the advancement of the target microbes to the log phase of growth during the testing procedure.
    • 在环境衍生的样品中存在或不存在预定的目标第一代环境来源的微生物通过向样品中加入测试培养基来确定,反之亦然。 测试培养基为目标微生物提供选择性生长培养基,并且包括只有目标微生物可以显着代谢并用于生长的特定营养物。通过将样品改变部分附加到其上来修饰该特定营养物,从而将营养物转化为营养物 -指示符。 只有当特定营养物质被目标微生物代谢时,样品更换部分被激活才能改变样品。 样品改变部分可以是改变样品的颜色(可见或不可见)或改变样品的电特性或改变样品的一些其它可检测特征的材料。 测试介质不必保持无菌(但显然必须没有可行的目标微生物),并且测试过程不必在无菌环境中进行。 该培养基还包括促进剂,其加速了目标微生物在测试过程中生长的对数阶段。

    • The invention relates to a target microbe-specific medium for detecting the presence or absence of a target microbe in an environmental or biological sample, the medium including: a) an effective amount of vitamin, amino acid, element and salt ingredients operable to allow viability and log phase reproduction of the target microbe in the presence of a nutrient-indicator and to aid the target microbe through lag phase and into log phase of growth in the sample; and b) an effective amount of a nutrient-indicator which is provided in an amount sufficient to support log phase growth of the target microbe of a sample until a detectable characteristic signal is produced in the medium/sample mixture during the log phase growth; the nutrient-indicator being incapable of supporting continued logarithmic growth of any viable non-target microbes in the medium/sample mixture to produce a detectable characteristic signal; and the nutrient-indicator being operable to alter a detectable characteristic of the medium/sample mixture if metabolized by the target microbe so as to confirm the presence or absence of the target microbe in the sample; wherein the medium lacks a gelling agent so that when the medium is mixed with a liquefied sample a liquid is formed, and wherein the ingredients in (a), and the nutrient-indicator are chosen such that growth of non-target microbes do not interfere with growth of the target microbe. The invention also relates to methods of detecting the presence or absence of a target microbe in which an environmental or liquid sample is mixed with the medium, and the mixture is then evaluated for the alteration of a detectable characteristic.
