摘要:
A method and device for determining the presence and concentration of total microbial contamination or the presence and concentration of a specific microbial species on a surface is described. The method consists of a means of a collection device and fluid for removing the microbes from the surface and suspending them in a fluid phase. An aliquot of the fluid phase is introduced into a disposable test ticket which allows filtration of the sample to remove extraneous substances including somatic cells, and concentration of the microbes. The total concentration of microbes is determined by adding a somatic and bacterial releasing reagent to a disposable test device which comprises a membrane containing the luminescent reagents luciferin and luciferase, and introducing the disposable test device into a luminometer that can read the luminescence from the underside.

A method for determining the presence and concentration of total microbial contamination or the presence and concentration of a specific microbial species on a surface is described. The method consists of a means of a collection device and fluid for removing the microbes from the surface and suspending them in a fluid phase. An aliquot of the fluid phase is introduced into a disposable test device which allows filtration of the sample to remove extraneous substances including somatic cells, and concentration of the microbes. The total concentration of microbes is determined by adding a bacterial releasing reagent and a luminescent reagent to the disposable test device and introducing the disposable test device into a luminometer that can read the luminescence from the side wall. The presence and concentration of specific microbial species is determined by adding an aliquot of the fluid phase described above to the dispoable test device, washing the sample, then adding a specific labeled antibody directed against the microbes to be detected to the test device, washing then adding a luminescent reagent to the disposable test device. The test device is then introduced into the luminometer. The relative light units determine the presence and quanity of microbes present. In both cases, the microbe is identified and/or the concentration is determined in less than 1 hour and generally in less than 5 minutes.
摘要:
A method for treating a streptococcal infection is disclosed using a nasal spray. The spray comprises an effective amount of a lysin enzyme genetically coded for by a C1 bacteriophage capable of infecting a group C Streptococcal bacteria, and a nasal spray carrier for delivering said lysin enzyme to a mouth, throat, or nasal passage.
摘要:
A method for the prophylactic and therapeutic treatment of bacterial infections is disclosed which comprises the treatment of an individual with an effective amount of a native or modified version of a lytic enzyme produced by a bacteria infected with a bacteriophage specific for said bacteria. The lytic enzyme is selected from a group consisting of shuffled lytic enzymes, chimericlytic enzymes, wherein the lytic enzyme is in an environment having a pH which allows for activity of said lytic enzyme; and a carrier for delivering said lytic enzyme. Additionally, a holin enzyme for puncturing the membrane may be included in the composition. This method, and composition can be used for the treatment of upper respiratory infections, skin infections, wounds, and burns, vaginal infections, eye infections, intestinal disorders and dental problems.
摘要:
The present invention discloses a method for treating Streptococcal infections of the upper respiratory tract, comprising administering an effective amount of a lysin enzyme produced by group C Streptococcal bacteria infected with a C1 bacteriophage specific for the bacteria to a mouth, throat, or nasal passage of a mammal, the method providing a concentration of from about 100 to 500,000 active enzyme units per milliliter of fluid in the environment of said nasal or oral passages.
摘要:
The present invention relates to an oral delivery system containing a group c streptococcal phage associated lysin enzyme for the prophylactic and therapeutic treatment of Streptococcal A throat infections, commonly known as strep throat.
摘要:
A rapid analyte collection and testing device, said device comprising a) a casing, said casing having) a first casing section, said first casing section containing an encapsulated buffer section containing a buffer, and asecond casing section, said second casing section comprising a window on a side of said second section, a complementary mechanism for attachment to said first casing section, an opening at a proximal end of said second casing section; and a non permeable platform strip positioned lengthwise within and extending beyond the second casing section. The non-permeable platform further contains a swab, said swab positioned at the distal end of said non-permeable platform strip, a lateral flow assay positioned downstream from said swab, and a tag, positioned upstream from the capture reagent site.
摘要:
The present invention relates to an oral delivery system containing a bacteriophage associated lysin enzyme for the treatment of [Streptococcus pneumoniae and] Hemophilus influenzae sinus/nasal infections.
摘要:
A composition and method for treating bacterial infections is disclosed which comprises the treatment of an individual with an effective amount of at least one lytic enzyme produced by a bacteria infected with a bacteriophage specific for said bacteria wherein at least one lytic enzyme is selected from the group consisting of shuffled lytic enzymes, chimeric lytic enzymes, holin enzymes, and combinations thereof. A carrier may be used for delivering the lytic enzyme. This method, and composition can be used for the treatment of upper respiratory infections, skin infections, wounds, and burns, vaginal infections, eye infections, intestinal disorders and dental problems.
