摘要:
The present invention comprises methods of inhibiting the interaction between group A streptococci or M protein and mucin or mucin producing cells by interfering with binding of M protein to sialic acid moieties of mucin, as well as methods of identifying modulators (e.g., inhibitors) of the interaction and novel M-protein binding receptors and mucin binding receptors. Also provided are methods of treating a group A streptococcal infection by inhibiting the interaction as well as pharmaceutical compositions which may be useful for this purpose.
摘要:
The full-length nucleic acid sequence of the C1 bacteriophage is disclosed in the present application. The specific regions of the C1 genome encoding the PlyC lysin have also been identified and sequenced. The invention relates to the pharmaceutical and diagnostic utility of these sequences and provides for development of pharmaceutical compositions for treating or preventing streptococcal infections in mammals, for compositions for decontamination of inanimate surfaces and for diagnosis of streptococcal infections.
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:
Novel bacteriophages of Bacillus anthracis, the nucleic acids of its genome, nucleic acids comprising nucleotide sequences of open reading frames (ORFs) of its genome, and polypeptides encoded by the nucleic acids, are described. Therapeutic and diagnostic compositions, methods and kits related thereto are also provided.
摘要:
The present invention discloses a composition for dermatological infections by the use of a lytic enzyme in a carrier suitable for topical application to dermal tissues. The method for the treatment of dermatological infections comprises administering a composition comprising effective amount of a therapeutic agent, with the therapeutic agent comprising a lytic enzyme produced by infecting a bacteria with phage specific for that bacteria.
摘要:
A composition and method for treating bacterial infections by the use of an effective amount of at least one lytic specific for the bacteria causing specific. The lytic enzyme is genetically coded for by a bacteriophage which may be specific for said bacteria. The enzyme may be at least one lytic protein or peptides in a natural or modified form.
摘要:
A nasal spray for treating a streptococcal infection is disclosed. 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.
