Capsular polysaccharide in Mycoplasma mycoides is a virulence factor.

J Infect Dis 2018 Dec 12. Epub 2018 Dec 12.

J. Craig Venter Institute, Rockville, MD USA.

Capsular polysaccharides have been confirmed to be an important virulence trait in many different Gram-positive and Gram-negative bacteria. Similarly, they are proposed to be virulence traits in minimal Mycoplasma that cause disease in humans and animals. In this study, goats were infected with the caprine pathogen Mycoplasma mycoides subsp. Read More

Snow angels - the microbiology of freshly fallen snow: implications for immunocompromised patients.

J Water Health 2018 Dec;16(6):1029-1032

Northern Ireland Public Health Laboratory, Department of Bacteriology, Belfast City Hospital, Lisburn Road, Belfast, Northern Ireland, BT9 7AD, UK E-mail: School of Biomedical Sciences, Ulster University, Cromore Road, Coleraine, BT52 1SA, Northern Ireland, UK and Centre for Experimental Medicine, Queen's University, 97 Lisburn Road, Belfast BT9 7BL, Northern Ireland, UK.

The frequency of seasonal snowfall results in the transient covering of gardens/amenity sites/open public spaces, which encourages recreational interaction mainly with children. No data is available demonstrating the microbiological composition of such fallen snow and therefore a study was undertaken to examine the microbiology of snow from 37 sites, estimating (i) total viable count (TVC), (ii) identification of bacteria, and (iii) the presence of Pseudomonas aeruginosa. Mean TVC count of 8. Read More

Quorum quenching: role of nanoparticles as signal jammers in Gram-negative bacteria.

Future Microbiol 2018 Dec 12. Epub 2018 Dec 12.

Department of Microbiology, Government College University, Faisalabad, Pakistan.

Quorum sensing (QS) is a cell density dependent regulatory process that uses signaling molecules to manage the expression of virulence genes and biofilm formation. The study of QS inhibitors has emerged as one of the most fascinating areas of research to discover novel antimicrobial agents. Compounds that block QS have become candidates as unusual antimicrobial agents, as they are leading players in the regulation of virulence of drug-resistant pathogens. Read More

Acetylation of HMGB1 by JNK1 Signaling Promotes LPS-Induced Peritoneal Mesothelial Cells Apoptosis.

Biomed Res Int 2018 12;2018:2649585. Epub 2018 Nov 12.

Department of Nephrology, The First Affiliated Hospital, Sun Yat-Sen University, China.

Increased high mobility group box 1 (HMGB1) in dialysis effluence is associated with the presence of peritoneal dialysis-related peritonitis in patients and peritoneal dysfunction in acute peritonitis mice model, but it remains unclear whether HMGB1 is involved in peritoneal mesothelial cell injury and functions via molecular posttranslational modifications by acetylation in this process. Here we first showed correlation between HMGB1 acetylation level in dialysis effluence of patients and occurrence of Gram-negative peritonitis. The increased level of acetylated HMGB1 was similarly observed under the lipopolysaccharides (LPS) treatment in both human peritoneal mesothelial cell line (HMrSV5) and mice visceral peritoneum tissue.

The large-scale production and isolation of recombinant protein is a central element of the biotechnology industry and many of the products have proved extremely beneficial for therapeutic medicine. Escherichia coli is the microorganism of choice for the expression of heterologous proteins for therapeutic application, and a range of high-value proteins have been targeted to the periplasm using the well characterised Sec protein export pathway.

Characterization of the Citrobacter rodentium Cpx regulon and its role in host infection.

Mol Microbiol 2018 Dec 9. Epub 2018 Dec 9.

Michael Smith Laboratories, University of British Columbia, Vancouver, BC, Canada.

Envelope-localized proteins, such as adhesins and secretion systems, play critical roles in host infection by Gram-negative pathogens. As such, their folding is monitored by envelope stress response systems. Previous studies demonstrated that the Cpx envelope stress response is required for virulence of Citrobacter rodentium, a murine pathogen used to model infections by the human pathogens enteropathogenic and enterohemorrhagic Escherichia coli; however, the mechanisms by which the Cpx response promotes host infection were previously unknown.

In recent years, the decreased efficacy of existing antibiotics toward management of emergent drug-resistant strains has necessitated the search for novel antibiotics from natural products. In this regard, sp is well known for producing variety of secondary metabolites of potential use. Therefore, we performed an investigation to isolate and identify sp from oral cavity for production of novel antimicrobial compounds. Read More

A multicenter epidemiology study on the risk factors and clinical outcomes of nosocomial intra-abdominal infections in China: results from the Chinese Antimicrobial Resistance Surveillance of Nosocomial Infections (CARES) 2007-2016.

Infect Drug Resist 2018 15;11:2311-2319. Epub 2018 Nov 15.

Department of Clinical Laboratory, Peking University People's Hospital, Beijing, China,

Objective: This study aimed to determine the risk factors for intra-abdominal infections (IAIs), assess the clinical outcomes of IAIs, and investigate the spectrum and antimicrobial resistance of major pathogens causing IAIs.

Patients And Methods: This prospective observational study enrolled patients from the Chinese Antimicrobial Resistance Surveillance of Nosocomial Infections (CARES) program between 2007 and 2016. Data on the clinicopathological factors and causative pathogens were collected. Read More

Reverse micelle-lipid nanocapsules: a novel strategy for drug delivery of the plectasin derivate AP138 antimicrobial peptide.

Introduction: Resistance to traditional antibiotics is an increasingly serious problem. Antimicrobial peptides (AMPs) have emerged as a new therapeutic class with great potential against infectious diseases, as they are less prone to induce resistance. Nanotechnology-based delivery strategies can improve the efficiency and stability of AMPs, particularly against proteolytic degradation. Read More

Macromolecular-clustered facial amphiphilic antimicrobials.

Nat Commun 2018 12 7;9(1):5231. Epub 2018 Dec 7.

Department of Chemistry and Biochemistry, Columbia, SC, 29208, United States.

Bacterial infections and antibiotic resistance, particularly by Gram-negative pathogens, have become a global healthcare crisis. We report the design of a class of cationic antimicrobial polymers that cluster local facial amphiphilicity from repeating units to enhance interactions with bacterial membranes without requiring a globally conformational arrangement associated with highly unfavorable entropic loss. This concept of macromolecular architectures is demonstrated with a series of multicyclic natural product-based cationic polymers. Read More
