Article Abstract

Two commercial MALDI-TOF MS systems were used to identify 18 isolates, belonging to the Peptoniphilus genus; also the 16S rRNA sequencing identity was compared against the MALDI-TOF MS system results. Bruker Biotyper system provided higher accuracy than Vitek MS system, however, adding spectra could allow a more reliable species level identification.

Background And Objectives: Enhanced environmental disinfection is linked to reduced hospital-acquired infection rates. In this study, we aimed to evaluate the efficacy of an emerging disinfection technology, a filtered far-UV-C handheld (FFUHH) device, for reducing bacterial loads on high-touch surfaces in shared clinical workrooms, and to isolate, identify and characterize clinically significant environmental pathogens.

Methods: We compared samples from high-touch items (dictation device, mouse, armchair, desk, and keyboard) before and after FFUHH treatment.

The formation of Tc-(VII)-Zr-(IV) species in nitric acid and their extraction in kerosene/tributyl phosphate (TBP) phases was studied. The technetium distribution coefficient ( ) was evaluated as a function of nitric acid concentration (1-7 M) and is in the range of 25-37, which is significantly higher compared to solutions that do not contain zirconium and confirms the synergism of their coextraction. Emphasis was placed on 1 M HNO solution, which is the initial concentration used in uranium extraction during spent nuclear fuel reprocessing.

Extended-spectrum beta-lactamases (ESBLs) producing Gram-negative bacteria are public health threats. This study aims to characterize ESBL-producing Gram-negative bacteria (GNB) isolated from surgical site infection patients. A multicenter cross-sectional study was conducted at four hospitals located in central (Addis Ababa), southern (Hawassa), northern (Debre Tabor), and Southwestern (Jimma) parts of Ethiopia.
