Bloodstream co-infection with and in a patient with a flare of ulcerative colitis - A case report and review of the literature.

was isolated in 2002 from the blood of a patient with appendicitis. We report a bacteremia with and in a patient with ulcerative colitis. grew in thioglycolate media and identification was confirmed with 16S rRNA sequencing.

Myoelectric interface for neurorehabilitation conditioning to reduce abnormal leg co-activation after stroke: a pilot study.

Background: The ability to walk is an important factor in quality of life after stroke. Co-activation of hip adductors and knee extensors has been shown to correlate with gait impairment. We have shown previously that training with a myoelectric interface for neurorehabilitation (MINT) can reduce abnormal muscle co-activation in the arms of stroke survivors.

A rare anaerobic cause of vertebral osteomyelitis and psoas abscess: A case study.

is an obligate anaerobe that forms part of the normal gastrointestinal flora. The advent of matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF) and 16s ribosomal RNA gene sequencing has led to increased detection of many rare anaerobic isolates, including Typical risk factors for bacteremia include dental procedures or spinal instrumentation. Here, we report a case of spondylodiscitis and psoas abscess in a patient with no obvious antecedent risk factors and explore the challenges in isolation of the organism from tissue samples.

Serum potassium changes during hypothermia and rewarming: a case series and hypothesis on the mechanism.

Introduction: Hypokalemia is known to occur in association with therapeutically induced hypothermia and is usually managed by the administration of potassium (K).

Methods: We reviewed data from 74 patients who underwent a therapeutic hypothermia protocol at our medical institution.

Results: In four patients in whom data on serum K and temperature were available, a strong positive correlation between serum K and body temperature was found.

inPhocus: Current State and Challenges of Phage Research in Singapore.

Bacteriophages and phage-derived proteins are a promising class of antibacterial agents that experience a growing worldwide interest. To map ongoing phage research in Singapore and neighboring countries, Lee Kong Chian School of Medicine, Nanyang Technological University Singapore (NTU) and Yong Loo Lin School of Medicine, National University of Singapore (NUS) recently co-organized a virtual symposium on Bacteriophage and Bacteriophage-Derived Technologies, which was attended by more than 80 participants. Topics were discussed relating to phage life cycles, diversity, the roles of phages in biofilms and the human gut microbiome, engineered phage lysins to combat polymicrobial infections in wounds, and the challenges and prospects of clinical phage therapy.

Wearable myoelectric interface enables high-dose, home-based training in severely impaired chronic stroke survivors.

Background: High-intensity occupational therapy can improve arm function after stroke, but many people lack access to such therapy. Home-based therapies could address this need, but they don't typically address abnormal muscle co-activation, an important aspect of arm impairment. An earlier study using lab-based, myoelectric computer interface game training enabled chronic stroke survivors to reduce abnormal co-activation and improve arm function.

Properties and mutation studies of a bacteriophage-derived chimeric recombinant staphylolytic protein P128: Comparison to recombinant lysostaphin.

P128 is a chimeric anti-staphylococcal protein having a catalytic domain from a bacteriophage K tail associated structural protein and a cell wall targeting domain from the bacteriocin-lysostaphin. In this study, we disclose additional properties of P128 and compared the same with lysostaphin. While lysostaphin was found to get inactivated by heat and was inactive on its parent strain biovar , P128 was thermostable and was lytic towards biovar demonstrating a difference in their mechanism of action.

Structural and functional studies of gpX of Escherichia coli phage P2 reveal a widespread role for LysM domains in the baseplates of contractile-tailed phages.

A variety of bacterial pathogenicity determinants, including the type VI secretion system and the virulence cassettes from Photorhabdus and Serratia, share an evolutionary origin with contractile-tailed myophages. The well-characterized Escherichia coli phage P2 provides an excellent system for studies related to these systems, as its protein composition appears to represent the "minimal" myophage tail. In this study, we used nuclear magnetic resonance (NMR) spectroscopy to determine the solution structure of gpX, a 68-residue tail baseplate protein.

Use of prophage free host for achieving homogenous population of bacteriophages: new findings.

We demonstrate that the prophage status of bacteria plays a critical role in achieving homogenous population of a phage preparation. When a lytic Staphylococcus bacteriophage 44AHJD was propagated in a Staphylococcus clinical isolate, the enriched phage showed 44AHJD phage virions along with the released prophages from the baiting host. The released prophage was identified as a siphophage by transmission electron microscopy.

Antistaphylococcal activity of bacteriophage derived chimeric protein P128.

Background: Bacterial drug resistance is one of the most significant challenges to human health today. In particular, effective antibacterial agents against methicillin-resistant Staphylococcus aureus (MRSA) are urgently needed. A causal relationship between nasal commensal S.

A novel bacteriophage Tail-Associated Muralytic Enzyme (TAME) from Phage K and its development into a potent antistaphylococcal protein.

Background: Staphylococcus aureus is a major cause of nosocomial and community-acquired infections. However, the rapid emergence of antibiotic resistance limits the choice of therapeutic options for treating infections caused by this organism. Muralytic enzymes from bacteriophages have recently gained attention for their potential as antibacterial agents against antibiotic-resistant gram-positive organisms.

Lysis-deficient phages as novel therapeutic agents for controlling bacterial infection.

Background: Interest in phage therapy has grown over the past decade due to the rapid emergence of antibiotic resistance in bacterial pathogens. However, the use of bacteriophages for therapeutic purposes has raised concerns over the potential for immune response, rapid toxin release by the lytic action of phages, and difficulty in dose determination in clinical situations. A phage that kills the target cell but is incapable of host cell lysis would alleviate these concerns without compromising efficacy.
