Similarity Analysis of Producing Carbapenemases Isolated from UTI and Other Infections.

is an important opportunistic pathogen responsible for severe infections, mainly urinary tract infections (UTIs) and pneumonia. Hospital epidemic infections caused by multiresistant strains of carbapenemase-producing are the most concerning. NDM-producing strains are resistant to a wide range of antibiotics and have become the most significant threat.

Improved RAPD Method for Fingerprinting.

Recently, methods based on the analysis of arbitrarily amplified target sites of genome microorganisms have been extensively applied in microbiological studies, and especially in epidemiological studies. The range of their application is limited by problems with discrimination and reproducibility resulting from a lack of standardized and reliable methods of optimization. The aim of this study was to obtain optimal parameters of the Random Amplified Polymorphic DNA (RAPD) reaction by using an orthogonal array as per the Taguchi and Wu protocol, modified by Cobb and Clark for isolates.

Epidemiological Analysis of Extended-Spectrum β-Lactamase-Producing Outbreak in a Neonatal Clinic in Poland.

is one of the most common etiological agents isolated from epidemic outbreaks in neonatal wards. We describe how an extended-spectrum β-lactamase-producing (ESBL-KP) outbreak in a neonatal ward was extinguished. During the outbreak, which lasted over two months, 26 neonates were tested for , and 42 environmental swabs were taken.

Evaluation of Chemical Changes in Laboratory-Induced Colistin-Resistant .

This study evaluates the electrical potential and chemical alterations in laboratory-induced colistin-resistant , as compared to the susceptible strain using spectroscopic analyses. The minimal inhibitory concentration (MIC) of colistin, ζ-potential and chemical composition analysis of strains are determined. The results obtained for the with induced high-level colistin resistance (MIC = 16.
