Colonisation in adult patients with nosocomial candidemia.

The aim of this prospective study was to investigate the association between Candida spp. isolated from blood culture and the colonisation of different anatomical sites of patients with candidemia, and to evaluate the colonisation dynamics and Pittet's index. Cultures were collected from the different anatomical sites of all the patients within 24 h of diagnosis of candidemia.

[Evaluation of the fully automated BACTEC MGIT 960 system for testing susceptibility of Mycobacterium tuberculosis to front line antituberculosis drugs and comparison with the radiometric BACTEC 460 TB method].

The performance of the fully automated BACTEC MGIT 960 (Becton Dickinson, Cockeysville, Md.) system for susceptibility testing of Mycobacterium tuberculosis to critical concentrations of 4 major antituberculosis drugs [streptomycin (STR), isoniazid (INH), rifampin (RIF) and ethambutol (EMB)] was evaluated with 100 clinical isolates and compared to that of the radiometric BACTEC 460 TB (Becton Dickinson, Sparks, Md.) system.

Antimicrobial resistance in gram-negative hospital isolates: results of the Turkish HITIT-2 Surveillance Study of 2007.

Resistance rates to amikacin, ciprofloxacin, ceftazidime, cefepime, imipenem, cefoperazone/sulbactam and piperacillin/tazobactam in Escherichia coli (n= 438), Klebsiella pneumoniae (n= 444), Pseudomonas aeruginosa (n= 210) and Acinetobacter baumanni (n=200) were determined with e-test in a multicenter surveillance study (Hitit-2) in 2007. ESBL production in Escherichia coli and K. pneumoniae was investigated following the CLSI guidelines.

Investigation of colistin sensitivity via three different methods in Acinetobacter baumannii isolates with multiple antibiotic resistance.

Background: In recent years there has been an increase in life-threatening infections caused by Acinetobacter baumannii with multiple antibiotic resistance, which has lead to the use of polymyxins, especially colistin, being reconsidered. The aim of this study was to investigate the colistin sensitivity of A. baumannii isolates with multiple antibiotic resistance via different methods, and to evaluate the disk diffusion method for colistin against multi-resistant Acinetobacter isolates, in comparison to the E-test and Phoenix system.
