BACKGROUND Pseudomonas aeruginosa is a leading cause of nosocomial infections worldwide. Resistance of P. aeruginosa strains to the broad-spectrum cephalosporins may be caused by extended-spectrum β-lactamases (ESBLs). OBJECTIVES The aim of this study was to determine the antimicrobial resistance patterns and prevalence of PER-1 and VEB-1 type genes among ESBL producing strains of P. aerugino...

Among 730 Escherichia coli, 438 Klebsiella pneumoniae, and 141 Proteus mirabilis isolates obtained between September 2000 and September 2001 in seven hospitals in Ho Chi Minh City, Vietnam, 26.6% were resistant to ceftazidime, 30% were resistant to cefotaxime, 31.5% were resistant to ceftriaxone, 15.9% were resistant to cefoperazone, and 6% were resistant to cefepime. Resistance to imipenem was...

Due to annually recurring mass gatherings in Makkah, Saudi Arabia could be a hot spot for the collection of multidrug-resistant strains such as Pseudomonas aeruginosa (P. aeruginosa). The various genotypes of extended spectrum beta-lactamases (ESBLs) are SHV, TEM, CTX-M types VEB, PER, BEL-1, BES-1, ESBL enzymes in P. aeruginosa. The present study aimed to identify the prevalence these genes in...

Background and Objectives. The aim of this study was to determine the frequency of bla NDM, bla PER, bla VEB, bla IMP, and bla VIM type genes among A. baumannii isolates from hospitalized patients in two hospitals in Tehran, Iran. Patients and Methods. Antibiotic susceptibility tests were performed by Kirby-Bauer disc diffusion and Broth microdilution methods. The frequency of MBL (metallo-beta...

Tema ovog rada jeste ispitivanje utica­ja boje na poverenje korisnika kada su u pitanju veb saj­tovi oblasti elektronskog bankarstva. Literatura koja se bavi upotrebom dizajnu pokazuje da boja ima značajan uticaj interakciju kupaca sa sajtovima. S obzirom je najvažnija karakteristika sajtova, cilj ove studije bio utvrdi odnos između njih ob­lasti Metoda korišćena za istra­živanje ovih odnosa bi...

A (formerly Alcaligenes) xylosoxidans is a newly emerging microorganism isolated with increased frequency from the lungs of patients with cystic fibrosis (CF), but information about its clinical relevance is limited (1). A. xylosoxidans is innately resistant to many antimicrobial drugs (2), except piperacillin, piperacillintazobactam, and imipenem, and moderately susceptible to ceftazidime (45%...
