Prostate biopsy is typically performed via either the transrectal or transperineal approach. MRI-targeted biopsy, whether using any of the three options of cognitive fusion, MRI-ultrasound fusion software, or in-bore MRI-guided biopsy, can also be performed via either transrectal or transperineal approaches. As an extension of traditional random prostate biopsy, the transrectal approach is far more commonly used for MRI-targeted biopsy due to its convenience. However, in the context of today's increasing multi-drug resistance of rectal flora, the transperineal approach is being used more often due to its lack of septic complications...

Marine microorganisms such as Shewanella spp., Vibrio spp., and Aeromonas spp. can cause sepsis secondary to a wound infection in the context of swimming. These microorganisms are most often susceptible to fluoroquinolones. Here, we report a unique case of Shewanella algae bacteremia associated with meningoencephalitis and disseminated via hematogenous spread secondary to a skin injury. The patient suffered the injury while swimming in saline water during a cruise holiday in Madagascar, and she was initially treated with amoxicillin...

INTRODUCTION: Infection of prostate gland following biopsy is common complication. Most common pathogen is E.coli. Since fluorochinolones are commonly prescribed as prophylaxis, infection caused by E.coli leads to complicated infections, especially due to fluoroquinolone-resistant species. The aim of this study was to evaluate the incidence of fluoroquinolone-resistant E.coli species in rectal swabs of patients undergoing prostate biopsy and to define appropriate antimicrobial agent as prostate biopsy prophylaxis...

Antibiotics in water have recently caused increasing concerns for public health and ecological environments. In this work, we demonstrated polydopamine-coated graphene oxide/Fe3O4 (PDA@GO/Fe3O4) imprinted nanoparticles coupled with magnetic separation for fast and selective removal of fluoroquinolone antibiotics in water. The nanoparticles were prepared by the self-polymerization of dopamine using sarafloxacin as a template. The imprinted PDA film of 10~20 nm uniformly covered the surface of GO/Fe3O4 providing selective binding sites...

OBJECTIVES: Proton pump inhibitor (PPI)-amoxicillin-fluoroquinolone triple therapy is recommended as a second-line treatment of Helicobacter pylori infection in the Maastricht V/Florence Consensus Report. However, the eradication rate of this standard salvage treatment is suboptimal. The objective of this study is to compare the efficacy of esomeprazole-bismuth-tetracycline-levofloxacin therapy (TL quadruple therapy) and esomeprazole-amoxicillin-levofloxacin triple therapy (AL triple therapy) in rescue treatment for H...

OBJECTIVES: Resistance to both macrolides and fluoroquinolones has been reported in Mycoplasma genitalium; however, due to limited diagnostics, studies are often small and confined to specific geographical areas. This study sought to determine the rate of predicted resistance in M. genitalium-positive specimens referred for diagnostic testing. METHODS: Seventy-four M. genitalium-positive specimens, referred to the national reference laboratory (2010-2013) from 19 centres across England, were blinded and anonymised...

INTRODUCTION: Resistance to second line tuberculosis drugs is common, but slow to diagnose with phenotypic drug sensitivity testing. Rapid molecular tests speed up diagnosis, but can only detect limited mutations. Whole genome sequencing (WGS) of culture isolates can generate a complete genetic drug resistance profile, but is delayed by the initial culture step. We previously successfully achieved WGS directly from sputum using targeted enrichment. CASE REPORT: A 29-year-old Nigerian lady was diagnosed with tuberculosis...

Intensive care unit (ICU) admission is a risk for multidrug-resistant (MDR) Pseudomonas aeruginosa, but factors specific to critically ill pneumonia patients are not fully characterized. Objective was to determine risk factors associated with MDR P. aeruginosa pneumonia among ICU patients. This was a retrospective case-control study of P. aeruginosa pneumonia in the ICU; cystic fibrosis and colonizers were excluded. Risk factors included comorbid conditions and prior healthcare exposure (anti-pseudomonal antibiotics, hospitalizations, nursing home, P...

The development of antimicrobial resistance has made it necessary to measure antimicrobial usage in animal production sectors. France is a major European producer of white veal calves, but few data were previously available for that sector, even though these young animals are particularly susceptible to infection and considered as a reservoir of antimicrobial resistance. A cross-sectional study was conducted on 186 batches of French calves to estimate the exposure of white veal calves to antimicrobials and identify the potential risk factors related to antimicrobial usage...

Antibiotics such as fluoroquinolones (FQLs) are commonly used to treat ocular infections but are also known to cause dermal melanocyte toxicity. The release of dispersed pigments from the iris into the aqueous humor has been considered a possible ocular side effect of the systemic administration of FQLs such as Moxifloxacin, and this condition is known as bilateral acute iris transillumination (BAIT). Bilateral acute depigmentation of iris (BADI) is a similar condition, with iris pigment released into the aqueous, but it has not been reported as a side effect of FQL...

The emergence of multidrug resistant microorganisms together with the decline in discovery and development of new antibiotics is of great concern in health-care policy. In this alarming context, an early and well-tailored antibiotic therapy is a relevant strategy not only to improve clinical outcome but also to avoid appearance and spreading of perilous resistant strains. One of the most common antibiotic classes is fluoroquinolones. They trap the DNA girase and/or topoisomerase IV on the DNA, resulting in DNA fragmentation...

In this work, a multi-class analytical method for determination of 22 frequently used pharmaceuticals was developed and validated. Analytes were from different classes for example macrolides, fluoroquinolones, tetracyclines, sulfonamides, anthelmintics, anesthetics, and others. Method was intended for analysis of aqueous samples so the sample preparation was done using solid-phase extraction (SPE). Different sorbents (C8, C18, polymeric, and ion exchange sorbents) combining different eluents (methanol, ethanol, acetonitrile, acetone, ethyl acetate) were investigated during development of sample preparation step...

In this study, membrane filtration tests showed that the membrane rejection degree of difloxacin hydrochloride (DFHC) increased significantly in the presence of Suwannee River DOM or Aldrich humic acid (2-10 mg-C/L). Titration experiments showed that the excitation and emission of Peak R belonging to DFHC exhibited blue shifts by 5 nm and 10 nm, respectively, in the presence of DOM. The presence of DFHC can, in turn, lead to more significant overlapping of the fluorescence peaks of the Suwannee River DOM and Aldrich humic acid...

Wastewater transport along sewers favors the colonization of inner pipe surfaces by wastewater-derived microorganisms that grow forming biofilms. These biofilms are composed of rich and diverse microbial communities that are continuously exposed to antibiotic residues and antibiotic resistant bacteria (ARB) from urban wastewater. Sewer biofilms thus appear as an optimal habitat for the dispersal and accumulation of antibiotic resistance genes (ARGs). In this study, the concentration of antibiotics, integron (intI1) and antibiotic resistance genes (qnrS, sul1, sul2, blaTEM, blaKPC, ermB, tetM and tetW), and potential bacterial pathogens were analyzed in wastewater and biofilm samples collected at the inlet and outlet sections of a pressurized sewer pipe...

Steady growth in the degree of antimicrobial resistance in Neisseria gonorrhoeae calls for the control of the spreading of resistance mutations. Here we present the data describing drug resistance mutations, the results of antimicrobial susceptibility tests, and molecular genotypes of 128 recent N. gonorrhoeae isolates collected across 9 regions of the Russian Federation. The mutations in chromosome genes penA, ponA, rpsJ, gyrA, parC, which determine the susceptibility of N. gonorrhoeae to penicillins, tetracyclines, and fluoroquinolones were detected by multiplex amplification followed by hybridization on a hydrogel microarray...
