Isolation and characterization of a secreted metalloprotease of Aspergillus fumigatus.
A metalloprotease (MEP) secreted by Aspergillus fumigatus was isolated from an alkaline protease-deficient mutant after the fungus was cultivated in the presence of collagen as the sole nitrogen andExpand
Nucleotide sequence of a genomic and a cDNA clone encoding an extracellular alkaline protease of Aspergillus fumigatus.
An Aspergillus fumigatus extracellular alkaline protease (ALP) which is an enzyme of the subtilisin family is a potential virulent factor of the fungus. The gene encoding ALP was isolated from aExpand
Characterization by DNA restriction endonuclease analysis of Listeria monocytogenes strains related to the Swiss epidemic of listeriosis.
Listeria monocytogenes strains responsible for outbreaks of listeriosis were studied by using serotyping and phage typing. An additional approach based on restriction endonuclease analysis (REA) ofExpand
Nucleotide sequence of a genomic and a cDNA clone encoding an extracellular alkaline protease of Aspergillus fumigatus.
An Aspergillus fumigatus extracellular alkaline protease (ALP) which is an enzyme of the subtilisin family is a potential virulent factor of the fungus. The gene encoding ALP was isolated from aExpand
Histoplasma capsulatum var. duboisii infection in a patient with AIDS: rapid diagnosis using polymerase chain reaction-sequencing.
We describe an original case of disseminated infection with Histoplasma capsulatum (Hc) var. duboisii in an African patient with AIDS who migrated to Switzerland. The diagnosis of histoplasmosis wasExpand
Cloning and disruption of the gene encoding an extracellular metalloprotease of Aspergillus fumigatus
Aspergillus fumigatus secretes a serine alkaline protease (ALP) and a metalloprotease (MEP) when the fungus is cultivated in the presence of collagen as sole nitrogen and carbon source. The geneExpand
Virulence of alkaline protease-deficient mutants of Aspergillus fumigatus.
The gene encoding the secreted alkaline protease, a suspected virulence factor of Aspergillus fumigatus, was inactivated by gene disruption. The disruption was performed by transformation of aExpand
Parachlamydia and Rhabdochlamydia in Premature Neonates
To the Editor: New members have recently been recognized in the order Chlamydiales (1). The family Rhabdochlamydiaceae includes R. porcellionis (a parasite of Porcellio scaber) and R. crassificans (aExpand
High prevalence of anorectal chlamydial infection in HIV-infected men who have sex with men in Switzerland.
Human immunodeficiency virus (HIV)-infected men who have sex with men (MSM) were enrolled in an anorectal Chlamydia trachomatis screening study. Anorectal Chlamydia DNA was detected in 16 (10.9%) ofExpand
Microbiological diagnosis of community-acquired respiratory tract infections by nucleic acid detection.
BACKGROUND Microbiological diagnostic procedures have changed significantly over the last decade. Initially the implementation of the polymerase chain reaction (PCR) resulted in improved detectionExpand
