We report retrospective analysis of the clinical and antimicrobial susceptibility data of 140 Streptococcus pseudopneumoniae isolates. Strains were isolated mostly from respiratory tract samples from patients with underlying diseases. In the case of infection, pneumonia, mainly aspiration pneumonia, was the most frequent (27.1% of the patients). We(More)
BACKGROUND Because clinical symptoms and biological markers are neither sensitive nor specific, newborns are frequently suspected of having an infection. In France, 30-50% of newborns are suspected of having early-onset sepsis (EOS) and many of them undergo laboratory tests and empirical antibiotic treatments while awaiting results. The aim of this study(More)
STUDY OBJECTIVE To estimate the prevalence of Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Mycoplasma genitalium (MG) in patients under 31 years of age admitted to the emergency department of the University Hospital of Montpellier, for which a urinalysis was performed. PATIENTS AND METHODS CT, NG and MG specific real-time PCRs were performed(More)
Acquired carbapenemases currently pose one of the most worrying public health threats related to antimicrobial resistance. A NDM-1-producing Salmonella Corvallis was reported in 2013 in a wild raptor. Further research was needed to understand the role of wild birds in the transmission of bacteria resistant to carbapenems. Our aim was to investigate the(More)
The genetic structures involved in the dissemination of blaCMY-2 carried by Proteus mirabilis isolates recovered from different gull species in the South of France were characterized and compared to clinical isolates. blaCMY-2 was identified in P. mirabilis isolates from 27/93 yellow-legged gulls and from 37/65 slender-billed gulls. It was carried by a(More)
BACKGROUND The objective of this study was to compare automated immunoenzymatic assay (IEA) with an isotopic reference method for determination of plasma folate, erythrocyte folate, and plasma vitamin B12 levels. METHODS Analytical performance including within-run and between-run imprecision was assessed on the automated IEA on the Access2 (Beckman(More)
We describe a case of sacroiliitis secondary to catheter-related bacteremia due to Mycobacterium abscessus (sensu stricto). This case confirms that MultiLocus sequence typing and variable-number tandem-repeat methods are very robust techniques to identify the pathogen species and to validate molecular epidemiological links among complex M. abscessus(More)
Candida glabrata has emerged as a major pathogen in invasive candidiasis in recent years. Currently, guidelines for invasive candidiasis treatment recommend fluconazole or an echinocandin as the first-line therapy. Nevertheless, the resistance of Candida glabrata to echinocandin is an emerging problem and has been partly associated with mutations in the(More)
