The stimulating role of syringic acid, a plant secondary metabolite, in the microbial degradation of structurally-related herbicide, MCPA.

PeerJ 2019 10;7:e6745. Epub 2019 Apr 10.

Department of Environmental Toxicology, Faculty of Health Sciences, Medical University of Gdańsk, Gdańsk, Poland.

The ability of microorganisms to degrade xenobiotics can be exploited to develop cost-effective and eco-friendly bioremediation technologies. Microorganisms can degrade almost all organic pollutants, but this process might be very slow in some cases. A promising way to enhance removal of recalcitrant xenobiotics from the environment lies in the interactions between plant exudates such as plant secondary metabolites (PSMs) and microorganisms.

BimC Is Required for Actin-Based Motility, Intracellular Survival, and Virulence.

Front Cell Infect Microbiol 2019 22;9:63. Epub 2019 Mar 22.

The Roslin Institute and Royal (Dick) School of Veterinary Studies, University of Edinburgh, Midlothian, United Kingdom.

The intracellular pathogen , the etiological agent of melioidosis in humans and various animals, is capable of survival and movement within the cytoplasm of host cells by a process known as actin-based motility. The bacterial factor BimA is required for actin-based motility through its direct interaction with actin, and by mediating actin polymerization at a single pole of the bacterium to promote movement both within and between cells. However, little is known about the other bacterial proteins required for this process. Read More

Paediatr Respir Rev 2019 Mar 1. Epub 2019 Mar 1.

Manchester Adult Cystic Fibrosis Centre, Manchester University Hospitals NHS Foundation Trust, Wythenshawe Hospital, Southmoor Road, Manchester M23 9LT, UK. Electronic address:

Aside from the traditional CF pathogens, Haemophilus influenzae, Staphylococcus aureus and Pseudomonas aeruginosa, there are an increasing number of organisms found to have chronic carriage in patients with cystic fibrosis, including gram-negative bacteria, non-tuberculous mycobacteria, anaerobic bacteria and fungal species. Some of these lower prevalence organisms, such as Burkholderia cenocepacia and Mycobacterium abscessus complex, are recognised as true pathogens associated with significant adverse clinical consequences, whilst for others the relative pathogenicity and need for treatment are unclear. This article will highlight some of the challenges in assessing what is a pathogen in CF and the potential implications of infection with different organisms for individual patients. Read More

The structure of lipopolysaccharide transport protein B (LptB) from Burkholderia pseudomallei.

Acta Crystallogr F Struct Biol Commun 2019 Apr 13;75(Pt 4):227-232. Epub 2019 Mar 13.

Division of Biological Chemistry and Drug Discovery, School of Life Sciences, University of Dundee, Dundee DD1 5EH, Scotland.

The thick outer membrane (OM) of Gram-negative bacteria performs an important protective role against hostile environments, supports cell integrity, and contributes to surface adhesion and in some cases also to virulence. A major component of the OM is lipopolysaccharide (LPS), a complex glycolipid attached to a core containing fatty-acyl chains. The assembly and transport of lipid A, the membrane anchor for LPS, to the OM begins when a heteromeric LptBFG protein complex extracts lipid A from the outer leaflet of the inner membrane.

Expanding the Toolbox of Broad Host-Range Transcriptional Terminators for Proteobacteria through Metagenomics.

ACS Synth Biol 2019 Apr 9;8(4):647-654. Epub 2019 Apr 9.

FFCLRP , University of São Paulo , 14049-901 Ribeirão Preto , São Paulo , Brazil.

As the field of synthetic biology moves toward the utilization of novel bacterial chassis, there is a growing need for biological parts with enhanced performance in a wide number of hosts. Is not unusual that biological parts (such as promoters and terminators), initially characterized in the model bacterium Escherichia coli, do not perform well when implemented in alternative hosts, such as Pseudomonas, therefore limiting the construction of synthetic circuits in industrially relevant bacteria, for instance Pseudomonas putida. In order to address this limitation, we present here the mining of transcriptional terminators through functional metagenomics to identify novel parts with broad host-range activity. Read More

Volgograd Anti-Plague Institute, Federal Service for Surveillance of Consumer Rights Protection and Human Welfare, Volgograd, 400131 Russia.

Evolution of microsatellites (or simple sequence repeats, SSRs) is a complex process that converts perfect repeats to novel structural elements with functions poorly understood, such as imperfect and compound microsatellites. An in silico analysis often Burkholderia pseudomallei genomes revealed 215683 micro-satellites, and more than 98% of them proved imperfect. The density of microsatellites in the genome ranged from 2922. Read More

Successful ceftazidime-avibactam treatment of post-surgery Burkholderia multivorans genomovar II bacteremia and brain abscesses in a young lung transplanted woman with cystic fibrosis.

Transpl Infect Dis 2019 Mar 20:e13082. Epub 2019 Mar 20.

Cystic Fibrosis Center, IRCCS Ca' Granda Foundation, Milan, Italy.

Burkholderia cepacia complex (Bcc) includes several phenotypically similar but genotypically distinct gram-negative bacteria (GNB) that can colonize the respiratory tract of Cystic Fibrosis (CF) patients. Pathogens are difficult to treat due to intrinsic resistance to multiple antibiotics and are associated to a more rapid decline in lung function and to increased mortality, particularly after lung transplantation. For all these reasons, chronic infection by Burkholderia (B) cenocepacia is presently considered a relative or absolute contraindication in almost all lung transplant centres. Read More

Potential of the Complex to Produce 4-Hydroxy-3-Methyl-2-Alkyquinolines.

Front Cell Infect Microbiol 2019 28;9:33. Epub 2019 Feb 28.

Institut Armand Frappier, Institut National de la Recherche Scientifique, Laval, QC, Canada.

A few species, especially , and , are known to produce and release various 4-hydroxy-3-methyl-2-alkylquinolines (HMAQs), a family of molecules analogous to the 4-hydroxy-2-alkylquinolines [aka 2-n-alkyl-4(1)-quinolones] of , which include the quinolone signal (PQS). However, while these exoproducts play several roles in virulence and survival, the available literature is very limited on their distribution and function in . In this perspective article, we studied the distribution of the operon, which encodes the enzymes involved in the biosynthesis of HMAQs, in the complex (Bcc) group. Read More
