Abstract: New improved formulations are described, comprising at least one composition, with or without another composition (at least one second composition), in which the at least one composition, a first composition, is an inhibitor of lipid A deacetylase resulting in permeabilization of an outer membrane of a susceptible microorganism to which it is provided to. The at least one second composition may be a streptogramin. The first composition, alone or in combination with another, may be used to improve and/or treat a wide variety of bacterial infections, providing, on its own better efficacy, bioavailability, and/or pharmacokinetics, as compared with at least other or alternative inhibitors of lipid A deacetylase, as well as no expected cardiotoxicity. When provided to a susceptible microorganism as a combination described herein, the combination may be provided independently or may be provided together (co-combined in a same formulation, or in different formulations).

Abstract: Novel antimicrobial compositions comprise at least a form of a fosfomycin (or suitable analogs, or derivatives thereof), and at least one sulfonamide (or suitable analogs, or derivatives thereof), and/or at least one diaminopyridine (or suitable analogs, or derivatives thereof). Said antimicrobial compositions generally include two or more of said components as a novel combination, provided in a single combination or formulation, or provided independently with overlapping exposures of the two or more components. These novel compositions, when provided as the two or more components, are effective against susceptible microorganisms, and are effective against susceptible drug-resistant microorganisms (e.g., bacteria, parasites), including multi-drug resistant bacteria.

Abstract: Co-agent combinations and/or formulations herein unexpectedly display significantly better antimicrobial activity (e.g., more efficacy and/or more potency) against anaerobic pathogens not previously considered targets. With three or more co-agents, selected from a group of a fosfomycin, a diaminopyridine, a sulfonamide, a beta lactam antibacterial, a bacterial beta-lactamase inhibitor, a bacterial fosfomycin-modifying enzyme, and a bacterial peptidoglycan synthesis inhibitor, the therapeutic potential of the three or more co-agents is expanded by targeting a broader spectrum of pathogens. Co-agents, by unexpected synergistic action in an anaerobic environment, are now active and efficacious against difficult to treat pathogenic anaerobes (including anaerobes that cannot utilize oxygen and/or reside in an anaerobic environment, some being inhibited by oxygen), as well as pathogens considered resistant or intolerant to at least one of the co-agents when used singly in an anaerobic environment.

Abstract: The invention relates to the combination of nitrogenated heterocyclic antibacterial compounds of formula (I) with other antibacterial compounds and the use of same as drugs. The nitrogenated heterocyclic compounds are of general formula (I) wherein R1 represents a (CH2)n-NH2 or (CH2)n—NHR radical, where R is a (C1-C6) alkyl and n is equal to 1 or 2; R2 represents a hydrogen atom; R3 and R4 together form an aromatic nitrogenated heterocycle with 5 apexes with 1, 2 or 3 nitrogen atoms optionally substituted by one or several R? groups, R? being selected in the group composed of a hydrogen atom and the alkyl radicals with 1 to 6 carbon atoms, in free form, as zwitterions, and in the form of salts of pharmaceutically acceptable inorganic or organic bases and acids.

Abstract: This invention relates generally to in vitro methods for inducing or enhancing expression of enteric bacterial antigens and/or virulence factors thereby producing antigenically enhanced enteric bacteria, to methods for using antigenically enhanced enteric bacteria and to vaccines comprising antigenically enhanced enteric bacteria. A Shigella bacterium having enhanced antigenic property is disclosed. A culture medium useful for culturing the Shigella comprises 0.05% to 3% bile or 0.025% to 0.6% of one or more bile acids or salts. In addition a divalent cation chelator can also be included in the culture medium. The bacteria culture is in a growth phase at early log phase and between early log phase and stationary phase. The enhanced antigenic property is a higher level of an immunogenic antigen when compared to the antigenic property of the same bacteria grown on brain heart infusion broth. Also, antibodies to Shigella bacteria or Shigella bacteria in samples are detected by immunoassays.
