Abstract: The present invention relates to a method for genotyping a diploid organism by cleaving segments of two alleles such that 7-20 nucleotide fragments that contain a suspected polymorphic locus are produced and comparing the masses of those fragments.

Abstract: This invention relates to a method for the rapidly determining the susceptibility of bacteria to antibiotics using histochemical detection of enzyme inhibition by the antibiotic.

Abstract: This invention relates to compounds that are efflux pump inhibitors and therefore are useful as potentiators of anti-fungal agents for the treatment of infections caused by fungi that employ an efflux pump resistance mechanism.

Abstract: The present invention relates to chemical compounds having the formula: or a pharmaceutically acceptable salt thereof. R1 is selected from the group consisting of: R2 is selected from the group consisting of hydrogen, CH3—, FCH2—, F2CH— R3 is selected from the group consisting of: X is selected from the group consisting of hydrogen, halogen, cyano, —NH2, —N(CH3)2, —HSO2NH2, —SO2NH2 and —SCH3. The subscript n is 0 or 1.

Abstract: This invention relates to compounds that are efflux pump inhibitors and therefore are useful as potentiators of anti-fungal agents for the treatment of infections caused by fungi that employ an efflux pump resistance mechanism.

Abstract: The present invention relates to methods for the analysis of polynucleotides including detection of variance in nucleotide sequence without the need for full sequence determination, full sequence determination of a polynucleotide, genotyping of DNA and labeling a polynucleotide fragment during the process of cleaving it into fragments.

Abstract: The present invention provides a novel strain of Microbispora corallina, means for identifying it, methods for culturing it at several different levels, two new antibiotics derived from the cultures and the physico-chemical characteristics of those compounds and their biological activity against a variety of microorganisms.

Abstract: This disclosure describes isolated or purified deoxyribonucleotide (DNA) sequences, useful for the development of antibacterial agents, which contain the coding sequences of bacterial genes which encode the components of a two-component regulatory pair. It further describes isolated or purified DNA sequences which are portions of such bacterial genes, which are useful as probes to identify the presence of the corresponding gene or the presence of a bacteria containing that gene. Also described are hypersensitive mutant cells containing a mutant gene corresponding to any of the identified sequences and methods of screening for antibacterial agents using such hypersensitive cells. In addition it describes methods of treating bacterial infections by administering an antibacterial agent active against one of the identified targets, as well as pharmaceutical compositions effective in such treatments.

Abstract: The use of compounds of the milbemycin class as inhibitors of efflux pumps in microbes or other cells is described, along with pharmaceutical compositions incorporating a milbemycin. Also described is a method of screening for compounds which inhibit a CDR1, CDR2, BEN, or FLU1 efflux pump or a pump with components having a high level of protein level sequence similarity with the components of those efflux pumps.

Abstract: The present invention relates to dihydro derivatives of the uridyl peptide antibiotics mureidomycin, pacidimycin and napsamycin which have antibiotic activity against a number of bacterial strains including strains resistant to current therapeutic antibiotics.
