BACKGROUND Metallo-beta-lactamase (MBL) producing Pseudomonas aeruginosa has emerged as a threat to hospital infection control, due to its multi-drug resistance, especially in intensive care units (ICUs). AIMS This study was carried out to detect MBL producing P. aeruginosa isolates from medical and surgical ICUs, to compare and evaluate different phenotypic methods currently in use and to de...
The NCCLS (2004) presented a new methodology to detect, by disk-diffusion agar, oxacillin-resistance using a cefoxitin disk. We identified coagulase-negative staphylococci (SCoN) to the species level and compared the use of cefoxitin disks (30 microg) with oxacillin disks (1 microg), agar dilution (minimum inhibitory concentration of oxacillin) and mecA gene detection in isolates of coagulase-n...
Background and Aims: Candidiasis is a fungal infection caused by Candida albicans. Uncontrolled use of antibiotics has resulted in drug resistance. This study has been conducted to find a suitable alternative for these drugs. Materials and Methods: Primarily, standard and clinical isolates of C.albicans were collected. In order to indentify clinical isolates from lambs, the conventional mycolo...
One hundred and eighty-three strains of gram-negative bacteria were isolated from 177 bacteremic patients during a 6-month period in 2004 at a teaching hospital in southern Thailand. Extended-spectrum beta-lactamases (ESBL) production was detected in K. pneumoniae, E. coli, and E. cloacae, at rates of 16/36 (44.4%), 3/59 (5.1%), and 2/13 (15.4%), respectively. All but one of the screened positi...
Interpretive disk diffusion breakpoints for caspofungin are proposed by evaluating 762 isolates of Candida spp., representing 10 different species obtained as part of the caspofungin clinical trials. Standardized broth microdilution reference tests were compared to the zone diameters observed with 5-microg caspofungin disks produced by two different disk manufacturers. Disk diffusion breakpoint...
Background: Ventilator Associated Pneumonia (VAP) is one of the serious complications of ventilator support occurring in ICUs. The aim of this study was to determine the susceptibility pattern of Acinetobacter baumannii (A. baumannii) isolated from patients with VAP by two methods: disk diffusion and E. test. Methods: This descriptive-cross sectional study was conducted in the four ICUs of Ras...
Background: Urinary tract infection (UTI) is one of the most prevalent infectious diseases and Escherichia coli is its common cause. The aim of this study was to assess the resistance patterns of E.coli in urinary tract infections and to determine the susceptibility of E.coli to commonly used antimicrobials and also to evaluate the options for empirical treatment of UTI. Methods: This stud...
