The Oxoid combination disk method for detecting extended-spectrum beta-lactamases (ESBLs) depends on comparing the inhibition zones of cefpodoxime (10-microg) and cefpodoxime-plus-clavulanate (10- plus 1-microg) disks. The presence of clavulanate enlarged the zones for all of 180 ESBL-producing klebsiellae by >/=5 mm, whereas zones for cefpodoxime-susceptible isolates and cefpodoxime-resistant ...

Combinations of voriconazole, fluconazole, and itraconazole with caspofungin were evaluated against 50 Candida glabrata isolates by the time-kill, disk diffusion, and Etest methods. The majority of antifungal combinations were indifferent. By the time-kill method, synergistic activity was detected with eight (16%) of the caspofungin-voriconazole and seven (14%) of the caspofungin-fluconazole co...

ba ckground: legionella pneumophila is  a  dangerous pathogenic bacterium can cause serious infectious diseases especially in hospitalized immuno-compromised patients. this bacterium is shown to be resistant against different antibiotics. resistance against a wide range of antibiotics is usually mediated by efflux pump in bacteria. efflux pumps are proteinaceous transporters localized in the cy...

BACKGROUND & OBJECTIVES The resistance of enteropathogenic bacteria to commonly prescribed antibiotics is increasing both in developing as well as in developed countries. Resistance has emerged even to newer, more potent antimicrobial agents. The present study was therefore undertaken to report the current antibiotic resistance in common bacterial enteropathogens isolated in a tertiary care hos...

We propose a method of distance determination based on the internal structure and dynamics of disk galaxies. The method relies on the universal luminosity pro le of a stellar disk represented by an exponential law. Calibrating nearby galaxies with known distances, it is found that the scale length of the disk is tightly correlated with the speci c combination of central surface brightness and r...

The response of a mesoscopic superconducting disk to perpendicular magnetic fields is studied by using the multiple-small-tunnel-junction method, in which transport properties of several small tunnel junctions attached to the disk are measured simultaneously. This allows us to make the first experimental distinction between the giant vortex states and multivortex states. Moreover, we experiment...

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...
