Trichosporon asahii (T. asahii) is an opportunistic pathogen that can cause life-threatening infections in immunocompromised patients, with high mortality rates up to 80% despite treated with antifungal drugs. The biofilms-forming ability of T. asahii on indwelling medical devices may account for the resistance to antifungal drugs. Berberine (BBR) has been demonstrated to have antifungal activity and synergistic effects in combination with antifungal drugs against pathogenic fungi. In the present study, the in vitro activities of BBR alone or combined with fluconazole (FLC), itraconazole (ITC), voriconazole (VRC), caspofungin (CAS) and amphotericin B (AMB) against planktonic forms and biofilms of 21 clinical T...

REVIEW
Derek E Moormeier, Kenneth W Bayles
Chronic biofilm-associated infections caused by Staphylococcus aureus often lead to significant increases in morbidity and mortality, particularly when associated with indwelling medical devices. This has triggered a great deal of research attempting to understand the molecular mechanisms that control S. aureus biofilm formation and the basis for the recalcitrance of these multicellular structures to antibiotic therapy. The purpose of this review is to summarize our current understanding of S. aureus biofilm development, focusing on the description of a newly-defined, five-stage model of biofilm development and the mechanisms required for each stage...

REVIEW
Gokhan Kuyumcu, T Gregory Walker
The placement of an inferior vena cava (IVC) filter is a well-established management strategy for patients with venous thromboembolism (VTE) disease in whom anticoagulant therapy is either contraindicated or has failed. IVC filters may also be placed for VTE prophylaxis in certain circumstances. There has been a tremendous growth in placement of retrievable IVC filters in the past decade yet the majority of the devices are not removed. Unretrieved IVC filters have several well-known complications that increase in frequency as the filter dwell time increases...

: Bacterial interference is an alternative strategy to fight against device-associated bacterial infections. Pursuing this strategy, a non-pathogenic bacterial biofilm is used as a live, protective barrier to fence off pathogen colonization. In this work, biofilms formed by probiotic Escherichia coli strain Nissle 1917 (EcN) are investigated for their potential for long-term bacterial interference against infections associated with silicone-based urinary catheters and indwelling catheters used in the digestive system, such as feeding tubes and voice prostheses...

Antimicrobial peptides (AMPs) are an abundant and varied group of molecules recognized as the most ancient components of the innate immune system. They are found in a wide group of organisms including bacteria, plants and animals as a defense mechanism against different kinds of infectious pathogens. Over the past two decades, a fast-growing number of AMPs have been identified/designed and their wide-spectrum antimicrobial activity has been deeply investigated. In recent years, there has been an increasing interest in the use of AMPs as alternative anti-biofilm molecules for the control of biofilm-related infections...

INTRODUCTION: Peripheral venous catheters (PVC) are medical devices most frequently used during hospital care. Although the frequency of specific PVC-related adverse events (PVCAEs) has been reported, the global risk related to the insertion of this device is poorly estimated. The aim of this study is to determine the incidence of PVCAEs during the indwell time, after catheter removal, and to identify practice-mirroring risk factors. METHODS: A prospective observational study was conducted as a part of a research project, called CATHEVAL, in one surgery ward and four medicine wards from three public general tertiary care hospitals in Northern France that were invited to participate between June-2013 and June-2014...

Bacterial biofilms may form on indwelling medical devices such as prosthetic joints, heart valves and catheters, causing challenging-to-treat infections. We have previously described the 'electricidal effect', in which bacterial biofilms are decreased following exposure to direct electrical current. Herein, we sought to determine if the decreased bacterial quantities are due to detachment of biofilms or cell death and to investigate the role that reactive oxygen species (ROS) play in the observed effect. Using confocal and electron microscopy and flow cytometry, we found that direct current (DC) leads to cell death and changes in the architecture of biofilms formed by Gram-positive and Gram-negative bacteria...

Urinary tract infections (UTIs) are clinically important problems that lead to serious morbidity and mortality, and indwelling urinary catheters are a major factor of UTIs. In this study, we applied clustered regularly interspaced short palindromic repeats (CRISPR) genome editing to generate ΔluxS mutant strains from clinical isolates of Escherichiacoli SE15, which is one of major pathogens and can cause colonization and biofilm formation in the catheter. A major regulatory pathway of such biofilm formation on medical devices is the quorum sensing mechanism via small molecule autoinducer-2 synthesized by LuxS enzyme...

Staphylococcal species are a leading cause of community- and nosocomial-acquired infections, where the placement of foreign materials increases infection risk. Indwelling medical devices and prosthetic implants are targets for staphylococcal cell adherence and biofilm formation. Biofilm products actively suppress proinflammatory microbicidal responses, as evident by macrophage polarization toward an anti-inflammatory phenotype and the recruitment of myeloid-derived suppressor cells. With the rise in prosthetic hip and knee arthroplasty procedures, together with the recalcitrance of biofilm infections to antibiotic therapy, it is imperative to better understand the mechanism of crosstalk between biofilm-associated bacteria and host immune cells...

Chryseobacterium species are widely distributed in nature and can rarely cause human infection. Few cases reported in hospitalized patients are in immunocompromised hosts with indwelling devices and associated comorbidities. Chryseobacterium species are usually multidrug resistant. We describe 2 cases of Chryseobacterium indologenes-associated pneumonia in neonates and review the published infant cases.

Fungal biofilms are complex, structured communities that can form on surfaces such as catheters and other indwelling medical devices. Biofilms are of particular concern with Candida albicans, one of the leading opportunistic fungal pathogens of humans. C. albicans biofilms include yeast and filamentous cells that are surrounded by an extracellular matrix, and they are intrinsically resistant to antifungal drugs such that resolving biofilm infections often requires surgery to remove the contaminated device. C...

The upper extremity is an uncommon site for deep vein thrombosis and, although most of these thrombotic events are secondary to catheters or indwelling devices, venous thoracic outlet syndrome is an important cause of primary thrombosis. Young, active, otherwise healthy individuals that engage in repetitive upper extremity exercises, such as those required by a military vocation, may be at an increased risk. We present the case of a Naval Officer diagnosed with venous thoracic outlet syndrome whereby a multimodal approach with early surgical decompression was used...
