Abstract: The present invention relates to isolated genetic sequences encoding proteins which direct the biosynthesis of the antibiotic everninomicin in Micromonospora carbonacea. The isolated biosynthetic gene cluster serves as a substrate for bioengineering of antibiotic structures.

Abstract: The present invention relates to an arbitrarily primed PCR-based method to identify genetic marker associated with a pathology, which comprises the steps of: a) collecting heterogeneous nucleic acid samples from diseased and healthy tissues; b) determining quantities of the nucleic acid pools by specific amplification of a fragment of glyceraldehyde-phosphate dehydrogenase (GAPDH) mRNA; c) amplifying nucleic acid pools of step b) using non-specific sense and antisense primers to obtain clear patterns of nucleic acid sequences; and d) subjecting amplified nucleic acid sequences to gel electrophoresis to obtain fingerprints of both diseased and healthy, wherein bands predominantly associated with diseased tissues are markers for the pathology. The present invention also relates to a RNA expression marker for the diagnosis of Crohn's disease, which comprises a 3.1 kb RNA sequence, and uses thereof.

Abstract: The present invention relates to a DNA probe adapted to be used as a PCR target for the detection of the presence of C. stellatoidea and a subgroup of C. albicans strains in a biological sample, which comprises the nucleic acid sequence set forth in SEQ ID NO:1 or any functional analogs thereof wherein the hybridization of the probe and the rRNA of C. albicans is substantially preserved. The present invention also relates to a method for the detection of trace amount of C. stellatoidea or a subgroup of C. albicans in a biological sample, which comprises the steps of: a) isolating DNA from said biological sample; b) amplifying said isolated DNA of step a) with paired oligonucleotides: 5' primer: 5' AAC TTA GAA CTG GTA CGG 3' (SEQ ID NO:2), 3' primer: 5' AGT AGA TAG GGA CAG TGG 3' (SEQ ID No:3); or 5' GAC TCT CAA CCT ATA AGG 3' (SEQ ID NO:4), 3' primer: 5' TTA AGC ATT GCT CCA AGA 3' (SEQ ID NO:5); c) isolating amplified DNA of step b) and determining the presence or absence of C.
