  • Patent number: 5739160
    Abstract: New Cyclopentane- or cyclopentene-beta-aminoacid derivatives and their isomers, acid additional salts and metal salt complexes have strong antimicrobial and broad-spectrum antimycotic acitivity. As antimycotics they are especially active against dermatophyte, and biphasic fungi. The new compounds are also low toxicity antibacterial agents, effective against Gram positive bacteria, including antibiotic-resistant strains. The new Cyclopentane- or cyclopentene-beta-aminoacid derivatives are useful in human or veterinary medicine for combating dermatomycosis or systemic mycosis or local or systemic bacterial infections. In addition, the new compounds can also be used as preservatives, especially for water, foods, or organic materials such as polymers, lubricants, paints, fibers, leather, paper or wood.

  • Patent number: 5489513
    Abstract: Polynucleotide and oligonucleotide probes are described for the diagnostic investigation of mycoses which are caused by Candida albicans. These gene probes are complementary to parts of the genome of C. albicans and are suitable for identifying C. albicans nucleic acids in any sample material, even that which has been amplified. They do not hybridise with nucleic acids from other fungi, bacteria, animals or plants. Processes are described for the diagnosis of C. albicans in clinical samples as well.
