Evaluation of fungaemia infections in a Hungarian university hospital between 1996 and 2009.

The incidence of Candida species causing bloodstream infections in the University Hospital of Szeged, Hungary, between 1996 and 2009, and the susceptibilities of these isolates to antifungal agents were evaluated.Automated blood culture systems (Vital, bioMérieux, Marcy-l'Etoile, France; and BACTEC 9120, Becton-Dickinson Diagnostic Systems, Sparks, USA) were used. The in vitro susceptibilities of the yeast isolates to antifungal agents were determined by the Etest method (AB Biodisk, Solna, Sweden).

Successful application of the DiversiLab repetitive-sequence-based PCR typing system for confirmation of the circulation of a multiresistant Pseudomonas aeruginosa clone in different hospital wards.

The applicability of the repetitive-sequence-based PCR (rep-PCR)-based DiversiLab system was tested compared with the pulsed field gel electrophoresis (PFGE) to type a phenotypically similar subset of a large collection of multiresistant Pseudomonas aeruginosa strains isolated during a 17-month period from patients treated in different wards including 4 intensive care units (ICUs). Five environmental P. aeruginosa isolates obtained from one of the ICUs were also included.

Incidence, antibiotic resistance and clonal relations of MRSA strains isolated from a Romanian university hospital.

Our aim was to estimate the frequency and characteristics ofmethicillin-resistant Staphylococcus aureus (MRSA) strains occurring in a Romanian teaching hospital. We retrospectively studied isolates from infected or colonized patients treated at the intensive care and surgical units during January 2004-December 2005. The antibiotic susceptibility of MRSA strains and the presence of mecA gene were determined.

Screening of isolates from faeces for carbapenem-resistant Bacteroides strains; existence of strains with novel types of resistance mechanisms.

Isolates from faecal samples (n = 224) from the UK and Hungary were screened for carbapenem-resistant Bacteroides strains and were consecutively investigated for the resistance mechanisms through detection of cfiA genes, the presence or lack of insertion sequence insertions in their upstream regions and the production of carbapenemase activities. In this way, a significant number of strains (n = 7, 3.1%) were recovered.

Molecular characterization of imipenem-resistant, cfiA-positive Bacteroides fragilis isolates from the USA, Hungary and Kuwait.

Fifteen Bacteroides fragilis isolates from the USA, Hungary and Kuwait were examined for carbapenem resistance, for carbapenemase activity and, with the use of various PCR-based methods and nucleotide sequencing, for cfiA genes and activating insertion sequence (IS) elements. All the B. fragilis isolates were cfiA-positive, 10 of the cfiA genes being upregulated by IS elements that are already known.

Karyotyping of Candida albicans and Candida glabrata isolates from recurrent vaginal infections by pulsed-field gel electrophoresis.

In the present study, 16 women with recurrent vulvovaginal candidiasis (RVVC) due to Candida albicans and Candida (Torulopsis) glabrata were followed for a period of 4 to 12 months, and 36 vaginal isolates were evaluated by pulsed-field gel electrophoresis (PFGE). Eleven women were infected by C. albicans and 5 by C.
