| 摘要 |
The invention concerns a portable self-contained biological sensor for detecting the presence of a biological agent such as a bacterium, virus, protozoa or toxins in a sample. Said sensor comprises in one common body (2) means for sampling (8) a sample of the medium, whether solid, liquid or gaseous, means for biological culture or amplification (4) of said sample, detection means (5) inducing a reaction for example on an impregnated reagent strip (12), said reaction being either colorimetric and visible to the naked eye through a transparent eyepiece (9), or detectable by an independent system. The sampling means (8) comprises a plug (3) capable of being screwed or nested on the biological sensor body (2) and a joint (15) providing sealing conditions and the culture medium (11) is comprised in a breakable cartridge (10) so as to enable the sample to be contacted with said culture medium (11). The invention is useful for detecting Bacillus anthracis. |
