Proteus mirabilis is a specific opportunistic pathogen of many infections including urinary tract (UTIs). Risk factors are linked with the acquisition multidrug-resistant (MDR) to 3 or more classes antimicrobials) strains. The resistance in extended-spectrum alpha-lactamase rare, but rising beta-lactamase (ESBL) producing strains matter concern. ?-lactamases and antibiotic modifying enzymes mai...
The aim of this study was to compare the prevalence of different virulence factor (VF) genes in extended-spectrum beta-lactamase (ESBL) producing Escherichia coli strains isolated from the Baltic Sea region. A total of 432 strains of phenotypically ESBL positive E. coli were collected from 20 institutions located in Estonia, Latvia, Lithuania, and the region of St. Petersburg in Russia from Jan...
BACKGROUND This study was carried out in Microbiology department of Army Medical College, Rawalpindi to find out the frequency of extended spectrum beta lactamase producing gram negative bacilli among clinical isolates recovered from clinical specimens received from Military Hospital, Rawalpindi. METHODS This study was carried out from 1st Jan 2002 to 30th Dec 2002. A total of 812 consecutive...
conclusions more than behalf of the wound isolates were esbl positive, and the presence of blaveb-1 was determined in less than half of these isolates. fortunately, resistance to imipenem and meropenem was low. results the majority of the wound isolates were resistant to augmentin (90%, n = 80) and cefpodoxime (87.6%, n = 78). however, the majority was susceptible to imipenem and meropenem. fif...
BACKGROUND AND PURPOSE Data on the epidemiology of OXA-type extended-spectrum beta (beta)-lactamases (ESBLs) are limited due to difficulty of identification by routine microbiology laboratories. We determined the prevalence rate of OXA-type beta-lactamases among extended-spectrum cephalosporin (ESC)-non-susceptible Pseudomonas aeruginosa isolates at a university hospital in southern Taiwan. M...
The prevalence of extended-spectrum beta-lactamase-producing strains was demonstrated in 5 of 44 (11.4%) Escherichia coli, 17 of 43 (39.5%) Klebsiella pneumoniae, 3 of 50 (6.0%) Enterobacter cloacae, and 2 of 25 (8.0%) Citrobacter freundii strains at a teaching hospital in China. Nineteen of these 27 strains expressed CTX-M-3 beta-lactamase (pI 8.6). A subset of the clinical isolates expressing...
background: and objectives: salmonella infections are endemic in many developing countries with poor sanitary conditions, but emerge sporadically as a serious public health threat in developed countries. infections with multidrug resistant (mdr) strains of salmonella have been associated with treatment failures. salmonella spp. resistant to extended spectrum cephalosporins are increasing in pre...
We investigated in vitro activities of piperacillin or cefoperazone alone and in combination with beta-lactamase inhibitors against Gram-negative bacilli. Piperacillin/tazobactam 8:1 lowered resistance for Escherichia coli, Serratia marcescens, Enterobactaer cloacae, Klebsiella pneumoniae and imipenem-susceptible Acinetobacter baumannii. When piperacillin was combined with sulbactam 2:1 or 4:1,...
