First Report of Klebsiella pneumoniae-Carbapenemase-3-Producing Escherichia coli ST479 in Poland.

An increase in the antibiotic resistance among members of the Enterobacteriaceae family has been observed worldwide. Multidrug-resistant Gram-negative rods are increasingly reported. The treatment of infections caused by Escherichia coli and other Enterobacteriaceae has become an important clinical problem associated with reduced therapeutic possibilities.

Occurrence of the aacA4 gene among multidrug resistant strains of Pseudomonas aeruginosa isolated from bronchial secretions obtained from the Intensive Therapy Unit at University Hospital in Bialystok, Poland.

The aim of this study was to investigate the prevalence of the aacA4 gene in a population of multidrug resistant strains of P. aeruginosa isolated from bronchial secretions obtained from the Intensive Therapy Unit (ITU). Twelve MDR isolates were tested for antibiotic susceptibility and the presence of the aacA4 gene.

The KPC type beta-lactamases: new enzymes that confer resistance to carbapenems in Gram-negative bacilli.

Antimicrobial resistance due to the continuous selective pressure from widespread use of antimicrobials in humans, animals and agriculture has been a growing problem for last decades. KPC beta-lactamases hydrolyzed beta-lactams of all classes. Especially, carbapenem antibiotics are hydrolyzed more efficiency than other beta-lactam antibiotics.

The presence of blaIMP genes on plasmids DNA isolated from multidrug-resistant Pseudomonas aeruginosa strains at University Hospital in Bialystok (Poland)--first report.

Resistance to carbapenems is emerging, and it is a great problem to therapeutics. Seven multidrug-resistant (MDR) of Pseudomonas aeruginosa strains were isolated from urine and bronchial specimens. All isolates showed resistance to imipenem and meropenem (MIC; > or =16 mg/L).

[Correlation between peak expiratory flow and selected indices of bronchial potency in children between 4 and 18 years of age].

The study was conducted on 474 children diagnosed at the Lung Function Laboratory of the Children' Hospital in Lublin in the year 1992. 55% of the analyzed children were males. The children's initial diagnosis were: bronchial asthma, allergic rhinitis, chronic respiratory disorders, diabetes mellitus, abnormalities of the thorax.
