Bacterial strain typing, or identifying bacteria at the strain level, is particularly important for diagnosis, treatment, and epidemiological surveillance of bacterial infections. This is especially the case for bacteria exhibiting high levels of antibiotic resistance or virulence, and those involved in nosocomial or pandemic infections. Strain typing also has applications in studying bacterial population dynamics.

Klebsiella oxytoca is the second most frequently identified species of Klebsiella isolated from hospitalized patients. Klebsiella spp. is difficult to identify using conventional methods and is often misclassified in clinical microbiology laboratories. K. oxytoca is responsible for an increasing number of multi-resistant infections in hospitals because of insufficient detection and identification. In this study, we propose a new...

Bakterie Klebsiella pneumoniae New Delhi, posiadające gen oporności na karbapenemy (blaNDM) zostały po raz pierwszy wyizolowane w 2008 roku w Szwecji od pacjenta wcześniej hospitalizowanego w Indiach. Bakterie te szybko rozprzestrzeniają się po całym świecie, a od 2011 roku występują również w Polsce. Stanowią one wysokie ryzyko epidemiologiczne, ponieważ gen oporności na karbapenemy przekazywany jest pomiędzy bakteriami poprzez...

Drastic changes in the bonding are found in amorphous hydrogenated carbon nitride (a-CNx:H) film as a function of nitrogen concentration (or N/C ratio). The total C-sp3 fraction and hardness shows a sharp decrease (at N/C = 0.40) whereas optical band gap and resistivity shows a gradual increase as nitrogen concentration increases from 0.07 to 0.58. Raman spectrum of a-CNx:H film is fitted with both Gaussian (integrated intensity...
