the objective of this study was to determine the phenotypic characteristics of kpc-producing pseudomonas aeruginosa and acinetobacter baumannii isolates. a case report study was performed at a tertiary burn care centre in tehran,  iran.  nine  isolates  of pseudomonas  aeruginosa  and  acinetobacter baumannii from a hospitalized case were isolated. the identity of isolates was confirmed and the...

Carbapenem resistance due to KPC has rarely been observed outside the United States. We noticed a sharp increase in carbapenem-resistant Klebsiella pneumoniae strains possessing KPC in Tel Aviv Medical Center from 2004 to 2006. Sixty percent of the isolates belonged to a single clone susceptible only to gentamicin and colistin and carried the bla(KPC-3) gene, while almost all other clones carri...

An understanding of the impact of antibiotics on the intestinal reservoir of KPC carbapenemase-producing Klebsiella pneumoniae (KPC-Kp) is important to prevent its emergence. We used a mouse model to examine the effect of antibiotic treatment on the establishment and elimination of intestinal colonization with KPC-Kp. Mice (10 per group) received subcutaneous antibiotics daily for 8 days. On da...

conclusions the incidence of mbls producing p. aeruginosa in patients with cf was not low. the findings indicate that the identification of drug-resistance patterns in p. aeruginosa and the detection of mbl-producing isolates are important in the prevention and control of infections. background respiratory infections caused by pseudomonas aeruginosa play an important role in the pathogenesis of...

introduction klebsiella pneumoniae is one of the most important gram-negative bacteria causing hospital-acquired infections. case presentation in this report is presented a patient with an abdominal infection caused by carbapenemase producing-klebsiella pneumonia (k. pneumonia). in spite of administrating the combination therapy, successive resistance to last-resort antimicrobial agents (colist...

background and objectives: klebsiella pneumoniae is an opportunistic pathogen responsible for up to 10% of nosocomial infections. the emergence and spread of multidrug resistant k. pneumoniae , mostly due to the production of extended-spec- trum β-lactamases (esbl) and carbapenemases, is often responsible for antibiotic treatment failure of these infections. we compared the antibiotic resistanc...

The molecular epidemiology of carbapenemase-producing Klebsiella pneumoniae (KPC) has been largely investigated, but limited clinical information is available. A case-control study was performed to evaluate the risk factors for KPC bacteremia in hospitalized patients. Cases were patients with KPC bacteremia and controls were patients with non-KPC bacteremia. A total of 85 patients were included...

During an island-wide PCR-based surveillance study of beta-lactam resistance in multidrug-resistant (MDR) Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Acinetobacter calcoaceticus-baumannii complex isolates obtained from 17 different hospitals, 10 KPC-positive Acinetobacter isolates were identified. DNA sequencing of the bla(KPC) gene identified KPC-2, -3, and -4 and a no...
