To obtain a rapid genotyping method of Candida albicans, three polymorphic microsatellite markers were investigated by multiplex PCR. The three loci, called CDC3, EF3, and HIS3, were chosen because they are on different chromosomes so as to improve the chances of finding polymorphisms. One set of primers was designed for each locus, and one primer of each(More)
To improve the diagnosis of invasive aspergillosis (IA), we developed a LightCycler PCR assay targeted to Aspergillus fumigatus and A. flavus mitochondrial DNA. To avoid contamination, fully automated nucleic acid extraction with the MagNA Pure LC apparatus was used. The linearity of the results was achieved over a 6-log range of input A. fumigatus DNA,(More)
BACKGROUND Immune restoration following combination antiretroviral therapy (cART) questions the maintenance of prophylaxis among HIV-infected patients with cryptococcosis. OBJECTIVE To describe the long-term outcome after the diagnosis of cryptococcosis at the cART era. DESIGN Multicentre cohort of patients with a diagnosis of cryptococcosis between(More)
A cytochrome b (cytb) gene quantitative PCR (qPCR) assay was developed to diagnose malaria in travelers. First, manual and automated DNA extractions were compared and automated DNA extraction of 400 μl of blood was found to be more efficient. Sensitivity was estimated using the WHO international standard for Plasmodium falciparum DNA and compared to that of(More)
Scabies is an ectoparasitic infestation caused by the mite Sarcoptes scabiei. Currently, S. scabiei is taxonomically divided into different varieties on the basis of host origin. Genetics-based research on scabies has been conducted, but the data on genetic diversity of populations of this mite in humans in Europe are lacking. We evaluated the genetic(More)
Human and animal fungal pathogens are a growing threat worldwide leading to emerging infections and creating new risks for established ones. There is a growing need for a rapid and accurate identification of pathogens to enable early diagnosis and targeted antifungal therapy. Morphological and biochemical identification methods are time-consuming and(More)
We report the first human case of dermatophytosis caused by Trichophyton bullosum in a 21-year-old male who had a skin lesion located on his forearm. The dermatophyte was isolated in culture and further identified by sequence analysis of internal transcripted spacer regions. The species T. bullosum is a zoophilic dermatophyte rarely isolated from the coat(More)
Candida glabrata is one of the most important causes of nosocomial fungal infection. We investigated, using a multiplex PCR, three polymorphic microsatellite markers, RPM2, MTI, and ERG3, in order to obtain a rapid genotyping method for C. glabrata. One set of primers was designed for each locus, and one primer of each set was dye labeled to read PCR(More)
Invasive aspergillosis, which is mainly caused by the fungus Aspergillus fumigatus, is an increasing problem in immunocompromised patients. Infection occurs by inhalation of airborne conidia, which are first encountered by airway epithelial cells. Internalization of these conidia into the epithelial cells could serve as a portal of entry for this pathogenic(More)
OBJECTIVES An increase in invasive aspergillosis (IA) due to azole-resistant Aspergillus fumigatus isolates has been reported for 10 years. Our study aimed to estimate the prevalence of azole resistance in isolates prospectively collected in patients with haematological diseases. METHODS One hundred and eighteen isolates were collected from 89 consecutive(More)
