The antibiotic includes a non-systemic gram negative antibiotic (such as, for example, fodaximicin) and formulation is prepared in a dosage form for delivery to the gastrointestinal tract.Also included are methods of treatment of a C. difficile infection in mammal that include administering to the digestive tract of the mammal the above described formulation. Such methods provide that the likelihood that the mammal shall experience a reoccurrence of the C. difficile infection is 70% or less.

Embodiments of the invention include methods and / or compositions for analysis of samples for C. difficile infection to determine whether or not an individual is at risk for having recurrent C. difficile infection or a CDI misdiagnosis. Methods include characterization of microflora composition from the gut, wherein alterations of the microflora gut composition are indicative of recurrence of infection. Methods include analysis of nucleic acids from the gut, such as 16S rRNA as being identifying of a particular bacteria in the analysis of bacterial populations of the gut.

The present invention relates to methods and compositions for reducing the risk and severity of C. difficile infection. It is based, at least in part, on the discovery that a restricted fraction of the gut microbiota, including the bacterium Clostridium scindens, contributes substantially to resistance against C. difficile infection. Without being bound by any particular theory, it is believed that this is achieved through the biosynthesis of secondary bile acids.

The present invention relates to methods and compositions for the treatment and / or prophylaxis of Clostridium difficile associated disease (CD AD). In particular, the invention relates to antibodies that bind to C. difficile antigens and are capable of inhibiting C. difficile infection, at least one symptom of C. difficile associated disease, shedding of C. difficile, and C. difficile associated mortality. The compositions of the present application comprise: mammalian or avian antibodies which bind to a C. difficile Toxin B; and mammalian or avian antibodies that bind to a C. difficile vegetative cell antigen and / or a C. difficile endospore antigen.

The invention discloses new application of thiopeptcin to preparation of medicine for treating diseases caused by clostridium difficile infection and complications of the diseases. The thiopeptcin has evident activity on the clostridium difficile and the drug-resistant strains of the clostridium difficile and has great clinical application significance. In-vivo tests prove that the thiopeptcin does not enter blood circulation when a patient takes the thiopeptcin orally. According to the features of intestinal administration, the invention further provides a thiopeptcin orally-taken preparation containing a safe and effective dose and a preparing method of the thiopeptcin orally-taken preparation.

The present disclosure provides compositions and methods for treating Clostridium difficile infection (CDI) including primary and recurrent CDI. In particular, the compositions and methods described herein are capable of achieving a CDI clearance rate of at least 80% through a single oral dose of a pharmaceutical composition comprising a freeze-dried fecal microbiota preparation.

Provided herein are analog and derivative compounds of inositol hexakisphosphate effective to treat a Clostridium difficile infection and to neutralize the bacterial toxins produced by the same. In addition, methods of treating the C. difficile infection and for neutralizing its toxins with the compounds are provided.

The present invention relates to recombinant Clostridium difficile antigens based on a polypeptide, consisting of or comprising an amino acid sequence having at least 80% sequence identity with an amino acid sequence consisting of residues 1500-700 of a C. difficile Toxin A sequence or a C. difficile Toxin B sequence; though with the proviso that the polypeptide does not include one or more Repeat Unit (RU) located between amino acid residues 1851-2710 of C. difficile Toxin A and / or residues 1853-2366 of a C. difficile Toxin B protein that consists of or comprises a first amino acid sequence and a second amino acid. Also provided is the use of said antigens for the prevention / treatment / suppression of Clostridium difficile infection (CDI), together with methods for generating said antigens, methods for generating antibodies that bind to said antigens, and the use of said antibodies for the prevention / treatment / suppression of CDI.

The present invention relates to methods and compositions for the treatment and / or prophylaxis of Clostridium difficile associated disease (CD AD). In particular, the invention relates to antibodies that bind to C. difficile antigens and are capable of inhibiting C. difficile infection, at least one symptom of C. difficile associated disease, shedding of C. difficile, and C. difficile associated mortality. The compositions of the present application comprise: mammalian or avian antibodies which bind to a C. difficile Toxin B; and mammalian or avian antibodies that bind to a C. difficile vegetative cell antigen and / or a C. difficile endospore antigen.

The invention features probiotic bacteria expressing Clostridium difficile SlpA, or fragment thereof, and its use for the treatment or prevention of Clostridium difficile infection and gut colonization.

The invention provides a protein interacted with clostridium difficile cytotoxin B. The protein is chondroitin sulfate protein polysaccharide CSPG4 or a polypeptide formed by 640 amino acids at the N end of the CSPG4 protein. The invention firstly finds that the CSPG4 has the function of a clostridium difficile cytotoxin B cell receptor, the toxicity of the clostridium difficile cytotoxin B can be obviously reduced by restraining the expression or the function of the CSPG4, and a new thought is provided for treating the clostridium difficile infection.

The present invention is directed to the use of nifuratel, or a physiologically acceptable salt thereof, to treat infections caused by bacteria species of the genus Clostridium. The invention is further directed to the use of nifuratel to treat Clostridium difficile infection (CDI) and in particular Clostridium difficile associated diarrhoea (CDAD).
