PLASMID-MEDIATED QUINOLONE RESISTANCE – PMQR

Fluoroquinolones (FQ) are broad-spectrum antimicrobial agents widely used to treat a range of infections in clinical medicine. However, the surveillance studies demonstrate that fluoroquinolone resistance rates increased in Enterobacteriaceae in the past years. FQ inhibit bacterial DNA synthesis by interfering with the action of two bacterial enzymes – DNA gyrase and topoisomerase IV. There are two categories of quinolone resistance mechanisms: chromosomally encoded and acquired

INVESTIGATIONS INTO THE RESISTANCE OF SIN GIRDERS REINFORCED WITH TENSIONED DIAGONAL BRACES

The study presents the means of increasing resistance of girders with corrugated web by enhancing their shear resistance due to the application of diagonal braces subjected to advantageous tension. Diagonal braces were used in the near-support zones, which increased the shear resistance of the girder. Then, the web carries a greater shear load associated with bending. Experimental investigations on increased shear resistance of girder webs were performed using girders with webs having a height

Currently, SIN girders available on the market have three basic web thicknesses of 2.0, 2.5 and 3.0 mm and heights ranging from 333 to 1500 mm. Guaranteed by the manufacturer, yield resistance of the corrugated web steel is fy = 215 MPa. Due to the web thickness, SIN girders are more stressed in shear compared with flat webs. The buckling

The drug resistance of these bacteria has been on the increase since the 1980s, leeding to their multi-drug resistance. Selective pressure, present mainly in the hospital environment, contributed to this phenomenon. However, also outside the hospital environment selective pressure comes into play, namely the use of antibiotics as promoters of growth in

As a result of these limitations, plant resistance has become the most widely used and effective management approach to control RKN in tomato (Fuller et al., 2008). In tomato, resistance to RKN is mediated by a single dominant R gene called Mi-1 that was introduced to cultivated tomato from a single cross with its wild relative Solanum peruvianum (formerly Lycopersicon peruvianum) (Kaloshian et al., 1998). However, the durability of Mi resistance is reduced

The accurate identification of species within the genus Staphylococcus is important because, according to the EUCAST and CLSI recommendations, the interpretation of the results of susceptibility testing for S. aureus and coagulase-negative staphylococci is different. Furthermore, the resistance to methicillin in S. aureus strains is detected using a cefoxitin disk, whereas in S. pseudintermedius – using

Gas Gangrene of Different Origin Associated with Clostridium perfringens Type A in Three Patients Simultaneously Hospitalized in a Single Department of Orthopedics and Traumatology in Poland

The objective of the study was to perform a comparative analysis of phenotypic and genetic similarity, determination of resistance profiles, detection of toxin-encoding genes and molecular typing of Clostridium perfringens isolates originating from patients with gas gangrene. The study encompassed three patients with a clinical and microbiological diagnosis of gas gangrene who were hospitalized in one of the hospitals of the Kujawsko-Pomorskie province in the same period of time between 8th

GUT MICROBIOTA IN CHRONIC KIDNEY DISEASE

metabolism are p-cresol sulphate (PCS) and nitric oxide synthetase inhibitor (ADMA) [15]. In vitro studies have shown the association of high PCS concentrations, both with aberrant osteoblast differentiation and proliferation, decrease in their survival rate, a PTH-dependent cAMP mediated transmission disorder and a reduction in PTH receptor expression. ADMA inhibits the differentiation of osteoblasts [15]. 4.4. Insulin resistance in CKD In 1980, in the work of DeFronzo et al., insulin resistance (IR

A Current Microbiological Picture of Mycobacterium Isolates from Istanbul, Turkey

-tuberculosis drug resistance remains a significant problem. Of the primary anti-tuberculosis drugs, isolates showing at least isoniazid (INH) and rifampin (RIF) resistance are defined as Multiple Drug-Resistant Tuberculosis (MDR-TB) (WHO 2019). In this study, we aimed to document Mycobacterium species isolated in a large metropolitan tertiary care hospital in Turkey. The laboratory procedures used to isolate the organisms were also compared. Similarly, the resistance rates to the 1st-line anti-tuberculosis

IMPROVEMENT OF WORKING CONDITIONS OF THE FREIGHT LOCOMOTIVE RUNNING GEAR

Summary. To improve the working conditions of the electric locomotive running part, it is necessary to decrease unsprung masses, lateral loads and the angle of attack and provide the third body with proper tribotechnical properties. A new scheme of the freight electric locomotive running gear is elaborated in the work, which ensures a decrease of unsprung masses, relative sliding of a wheel on the rail and an angle of attack that provides resistance to the destruction of the third body in the

THE STRINGENT RESPONSE AND ITS INVOLVEMENT IN THE REACTIONS OF BACTERIAL CELLS TO STRESS

Bacterial cell resistance to stress and the stringent response The stringent response is not only a form of response to a deficiency in nutritional substances, but it is probably induced by many stress factors that influence bacteria, both on the surface and inside of plants

Only for novobiocin and bacitracin, the differences between bacilli and coccobacilli were observed, while all bacilli were resistant to bacitracin and susceptible to novobiocin, the opposite was observed in coccobacilli.

KPC-2-producing Klebsiella pneumoniae ST11 in a Children’s Hospital in Poland

Four Klebsiella pneumoniae isolates from children hospitalized over 10 months in an intensive care unit in a children’s teaching hospital in Poland were analyzed. All of the isolates belonged to a single pulsotype and sequence type (ST) 11, and produced the KPC-2 carbapenemase and extended-spectrum β-lactamase (ESBL) CTX-M-15. They were resistant to a variety of antimicrobials, and their β-lactam resistance patterns were typical for KPC producers. This is one of few cases of

Fluctuation enhanced gas sensing using UV irradiated Au-nanoparticle-decorated WO3-nanowire films

WO3 nanowires (WO3-NWs) decorated with gold nanoparticles (AuNPs) were utilized in resistive gas sensor devices to detect ethanol by use of fluctuation enhanced sensing (FES).  The experimental system records both DC resistance and fluctuations of the sensing film. Our data verify that the sensitivity and selectivity of the gas sensor are improved by applying FES when the sensor is stimulated with a combination of UV light and heating. We conclude that UV light can produce improved gas

Evaluation of The Pathogenic Potential of Insecticidal Serratia marcescens Strains to Humans

Introduction Due to the growing resistance of insects to synthetic pesticides, there is an urgent need for new biopreparations. Serratia marcescens is a species of Gram-negative rods (Hejazi and Falkiner 1997) that produces substances useful in different branches of industry and medicine (Siva et al. 2012). Some S. marcescens strains have been recognized as opportunistic or facultative pathogens of insects. They cause lethal septicemia after penetration into the hemocoel. The first step of

Wireless sensing of open loop micro inductors using Helmholtz coil

This paper reports wireless sensing of open loop micro inductors parameters i.e. distributed capacitance, inductance, resistance and Q factor in presence uniform magnetic fields generated by Helmholtz coils pair. A frequency dependent analytical model is developed which models the inductively coupled system including the effects generated by the presence of test micro coil in uniform magnetic field. Micro inductor parameters are extracted from the remotely measured impedance signal and compared
