Device for rapid detection and identification of single microorganisms without preliminary growth
InactiveUS20050221403A1Rapid and reliable detectionRapid and reliable and identificationBioreactor/fermenter combinationsBiological substance pretreatmentsMicroorganismFiltration
This invention describes a device consisting of a micro channel plate, filter, and porous holder for filter, which is substituted by a pure agar block during method performance, and supportive structural elements. The device is intended for rapid detection and / or identification of microorganisms. Microorganisms are trapped by filtration in long (diameter / length=1 / 10-1 / 100), cylindrical, parallel, micro-channels that are open from both sides and attached to a filter from one side. A micro channel plate houses a multiplicity of micro channels (possible diameter of each channel=1-30 μm, length 100-1000 μm, and number on centimeter2−100,000-1,000,000). The micro channel plate with cells trapped on the surface of the filter is attached to an agar block impregnated by artificial substrate(s) so that the molecules of the artificial substrates will fill all micro channels. Trapped cells produce colored or fluorescent molecules from artificial substrates. These molecules are collected in the very small volume of a micro channel. The extremely small volume of a micro channel (1 / 25 million part of milliliter) allows it to collect a detectable concentration of color or fluorescent substances in a very short time (several minutes). Even one cell from a filtrated sample can be detected by the enzyme—artificial substrate method and / or identified by enzyme immunoassay.

Kit for detecting non-pathogenic or pathogenic influenza a subtype h5 virus
InactiveUS20040142319A1High sensitivityStrong specificitySugar derivativesMicrobiological testing/measurementReverse transcriptaseHaemagglutination inhibition
Current methods for detecting influenza A subtype H5 virus, for example cell culture, haemagglutination-inhibition, fluorescent antibody and enzyme immunoassay, and reverse transcriptase polymerase chain reaction (RT-PCR) may have the disadvantages of low sensitivity and low specificity. Furthermore, such methods are relatively difficult to use, and may not be suitable for routine detection on a daily basis. The kit for detecting H5 virus of this invention may provide a user-friendly alternative that is relatively more sensitive and specific to H5 virus. The detection kit utilizes two specially designed primers A and B for the replication of H5 virus, and a specific capture probe for immobilizing the amplified viral RNA. An additional primer C is also designed for the detection of pathogenic H5 virus. The detection of H5 virus by the detection kit may be accomplished within one day if desired.
