Bacteriuria and asymptomatic infection in chronic patients with indwelling urinary catheter: The incidence of ESBL bacteria.

Urinary tract infections due to the presence of a urinary catheter represent a real problem for patients who have to carry such an invasive device for a long time.Our aim was to identify the susceptibility of extended spectrum beta lactamases (ESBL) versus non-ESBL bacteria to antibiotics in urinary tract infections in patients who are chronic carriers of urinary catheters.The retrospective study included a period of 5 years, a total of 405 patients who are chronic carriers of urinary catheters, admitted to rehabilitation and palliative care units.

Analysis of Romanian Bacteroides isolates for antibiotic resistance levels and the corresponding antibiotic resistance genes.

As part of an ESCMID Study Group on Anaerobic Infections (ESGAI) project, a study was conducted to measure the antibiotic susceptibilities and corresponding gene contents of 53 Bacteroides fragilis group strains isolated in Romania. The antibiotic resistance data was comparable with the data found for other East-European countries. Here, no resistant isolate was found for imipenem, metronidazole and tigecycline.

[Antimicrobial use and its correlations with the frequency of carbapenem-resistant Pseudomonas aeruginosa strains in a hospital setting].

One of the major causes leading to increased antibiotic resistance is excess antimicrobial consumption. We have analysed the correlation between antibiotic use and frequency of carbapenem-resistant Pseudomonas aeruginosa (CRPA) strains in the general intensive care unit of a university hospital Antibiotic use was expressed as number DDD (daily defined doses)/100 occupied hospital bed-days (BD). CRPA incidence rates were determined by number of unique isolates reported to 100,000 BD.

[Cumulative antibiogram--means of following local resistance phenomena based on material gathered in the laboratory of microbiology].

The cumulative antibiogram (CA) represents a report which summarizes the susceptibility of commonly isolated microorganisms to usual antibiotics in a defined period of time. We have evaluated the local resistance data during the year 2007 by generating CA from the bacteriology laboratory's database in Mures County Emergency Clinical Hospital for 3 categories of microorganisms: Gram-positive cocci, Gram-negative enteric rods and non-fermenters. A total of 1382 individual antibiotic susceptibility reports were analysed.

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.

[Emphasizing of Blastocystis hominis on culture media].

The aim of our study was to determine the frequency of Blastocystis hominis in the stool specimens sent to the Parasitological Laboratory of the Mureş County Hospital between October 2003 and May 2004. The 124 inoculated specimens showed positive values in 41.93%.
