摘要:
The present invention relates to methods for universal bacterial detection, for specific detection of the common bacterial pathogens, and for specific detection of commonly encountered and clinically relevant bacterial antibiotic resistance genes directly from clinical specimens or, alternatively, from a bacterial colony. The core of this invention consists primarily of the DNA sequences from all species-specific genomic DNA fragments selected by hybridization from genomic libraries or, alternatively, selected from data banks as well as any oligonucleotide sequences derived from these sequences which can be used as probes or amplification primers for PCR or any other nucleic acid amplification methods. This invention also includes DNA sequences from the selected clinically relevant antibiotic resistance genes. Diagnostic kits comprising such primers and probes are also provided.
摘要:
The present invention relates to DNA-based methods for universal bacterial detection, for specific detection of the common bacterial pathogens Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Proteus mirabilis, Streptococcus pneumoniae, Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecalis, Staphylococcus saprophyticus, Streptococcus pyogenes, Haemophilus influenzae and Moraxella catarrhalis as well as for specific detection of commonly encountered and clinically relevant bacterial antibiotic resistance genes directly from clinical specimens or, alternatively, from a bacterial colony. The above bacterial species can account for as much as 80% of bacterial pathogens isolated in routine microbiology laboratories. The core of this invention consists primarily of the DNA sequences from all species-specific genomic DNA fragments selected by hybridization from genomic libraries or, alternatively, selected from data banks as well as any oligonucleotide sequences derived from these sequences which can be used as probes or amplification primers for PCR or any other nucleic acid amplification methods. This invention also includes DNA sequences from the selected clinically relevant antibiotic resistance genes. With these methods, bacteria can be detected (universal primers and/or probes) and identified (species-specific primers and/or probes) directly from the clinical specimens or from an isolated bacterial colony. Bacteria are further evaluated for their putative susceptibility to antibiotics by resistance gene detection (antibiotic resistance gene specific primers and/or probes). Diagnostic kits for the detection of the presence, for the bacterial identification of the above-mentioned bacterial species and for the detection of antibiotic resistance genes are also claimed. These kits for the rapid (one hour or less) and accurate diagnosis of bacterial infections and antibiotic resistance will gradually replace conventional methods currently used in clinical microbiology laboratories for routine diagnosis. They should provide tools to clinicians to help prescribe promptly optimal treatments when necessary. Consequently, these tests should contribute to saving human lives, rationalizing treatment, reducing the development of antibiotic resistance and avoid unnecessary hospitalizations.

This invention relates to formulations for the prevention of infection and/or abnormal conditions of mucosae and/or skin caused by any pathogen and/or any disease, and more particularly for the prevention of sexually transmitted infections specially HIV and HSV. This invention also relates to formulations for the treatment of infection and/or abnormal conditions of skin and/or mucosac and more particularly for the treatment of herpetic lesions. The formulations could be used as a prophylactic agent to prevent accidental infection of health care workers. The formulations could be used for the healing and/or treatment of bum wounds and prevention of further infection. This invention also relates to the development of a unique vaginal/ano-rectal applicator for the uniform delivery of any topical formulations to treat and/or prevent any infection and/or abnormal conditions of mucosa cavity caused by any pathogen and/or disease.
摘要:
Four highly conserved genes, encoding translation elongation factor Tu, translation elongation factor G, the catalytic subunit of proton-translocating ATPase and the RecA recombinase, are used to generate species-specific, genus-specific, family-specific, group-specific and universal nucleic acid probes and amplification primers to rapidly detect and identify algal, archaeal, bacterial, fungal and parasitical pathogens from clinical specimens for diagnosis. The detection of associated antimicrobial agents resistance and toxin genes are also under the scope of the present invention.

Embodiments disclosed herein relate to methods and compositions for species-specific detection of bacterial and fungal nucleic acids and nucleic acids of antibiotic resistance genes.
摘要:
A formulation is disclosed for the treatment of diseases caused by an infectious agent which acquires host membranes protein during its life cycle. The formulation is a targeting pharmaceutical composition. It comprises a ligand capable of binding the host membrane proteins coupled to a lipid-comprising vesicle, which may comprise or not a drug effective in the treatment of the disease. Specific liposomes bearing anti-HLA-DR or anti-CD4 antibodies comprising or not antiviral drugs, namely anti-HIV drugs, are disclosed and claimed. A method of formulation as well as a method of using the formulation in the treatment of a disease are also disclosed.
摘要:
The present invention relates to a method for universal detection of bacteria in biological samples and for specific detection of Escherichia coli, Klebsiella pneumoniae, Enterococcus faecalis, Pseudomonas aeruginosa, Proteus mirabilis, Staphylococcus saprophyticus, Streptococcus pneumoniae, Moraxella catarrhalis and Haemophilus influenzae in urine or any other biological samples, said method comprising denaturation of bacterial DNA to single stranded form and either fixing it on a support or leaving it in solution, contacting said single stranded genetic material with a labeled probe selected from the group consisting of i) fragments of chromosomal DNA of the above-mentioned bacteria and ii) synthetic oligonucleotides whose sequences are derived either from the said fragments of chromosomal DNAs or from sequences available in data banks, all (i and ii) probes being capable to hybridize specifically to their chromosomal DNA or, in case of universal probes, to any bacterial chromosomal DNA.
