55 results about "Protozoan infection" patented technology

The invention is directed to a treatment of diseases that are accompanied by quantitative and / or qualitative changes of blood extracellular DNA and, more particularly, to a treatment of systemic bacterial, fungal and protozoan infections. The inventive method comprises introducing a treatment agent into a circulating blood system of a patient diagnosed with systemic infection caused by bacteria, fungi or protozoa, wherein said treatment agent destroys extracellular DNA in said blood of said patient and wherein said treatment agent used to destroy said extracellular DNA is a DNase enzyme: said agent being administered in doses and regimens which are sufficient to decrease the average molecular weight of circulating extracellular blood DNA in the blood of said patient; such decrease in the average molecular weight can be measured by gel electrophoresis of extracellular blood DNA fraction from the blood of said patient. A DNase enzyme may be applied in a dose and regimen that provide a DNase DNA hydrolytic activity measured in blood plasma that exceeds 1.5 Kunitz units per 1 ml of blood plasma for more than 12 hours within a period of 24 hours.

Polypeptide and polynucleotide vaccines effective to treat or prevent infection of a mammal, such as a dog, a cat, or a human, by a protozoan. Methods of treatment and prevention are also provided, including therapeutic administration of the vaccine to an infected mammal to prevent progression of infection to a chronic debilitating disease state. Preferred embodiments of the polynucleotide vaccine contain nucleotide coding regions that encode polypeptides that are surface-associated or secreted by T. cruzi. Optionally the efficacy of the polynucleotide vaccine is increased by inclusion of a nucleotide coding region encoding a cytokine. Preferred embodiments of the polypeptide vaccine include immunogenic peptides that contain membrane transducing sequences that allow the polypeptides to translocate across a mammalian cell membrane.

The present invention provides novel compounds (e.g., compounds of Formula (I)), and pharmaceutically acceptable salts, solvates, hydrates, polymorphs, co-crystals, tautomers, stereoisomers, isotopically labeled derivatives, prodrugs, and compositions thereof. Also provided are methods and kits comprising the inventive compounds, or compositions thereof, for treating and / or preventing a fungal or protozoan infection, inhibiting the activity of a fungal or protozoan enzyme, killing a fungus or protozoon, or inhibiting the growth of a fungus or protozoon. The fungus may be a Candida species, Aspergillus species, or other pathogenic fungal species. The compounds of the invention may inhibit the activity of fungal or protozoan cytochrome b and / or fungal or protozoan Hsp90. The present invention also provides synthetic methods of the inventive compounds.
