School of Applied Biosciences, Kyungpook National University, Daegu, Republic of Korea.

Variable region analysis of 16S rRNA gene sequences is the most common tool in bacterial taxonomic studies. Although used for distinguishing bacterial species, its use remains limited due to the presence of variable copy numbers with sequence variation in the genomes. In this study, 16S rRNA gene sequences, obtained from completely assembled whole genome and Sanger electrophoresis sequencing of cloned PCR products from Serratia fonticola GS2, were compared.

A dynamic preferred direction model for the self-organization dynamics of bacterial microfluidic pumping.

Soft Matter 2019 Feb 6. Epub 2019 Feb 6.

Theoretische Physik III, Universität Bayreuth, 95440 Bayreuth, Germany.

It is known that some flagellated bacteria like Serratia marcescens, when deposited and affixed onto a surface to form a "bacterial carpet", self-organize in a collective motion of the flagella that is capable of pumping fluid through microfluidic channels. We set up a continuum model comprising two macroscopic variables that is capable of describing this self-organization mechanism as well as quantifying it to the extent that an agreement with the experimentally observed channel width dependence of the pumping is reached. The activity is introduced through a collective angular velocity of the helical flagella rotation, which is an example of a dynamic macroscopic preferred direction. Read More

Pangenome of Serratia marcescens strains from nosocomial and environmental origins reveals different populations and the links between them.

Sci Rep 2019 Jan 10;9(1):46. Epub 2019 Jan 10.

Laboratorio de Bioproducción, Plataforma de Bioinsumos, INIA Uruguay, Ruta 48 Km 10, Canelones, Uruguay.

Serratia marcescens is a Gram-negative bacterial species that can be found in a wide range of environments like soil, water and plant surfaces, while it is also known as an opportunistic human pathogen in hospitals and as a plant growth promoting bacteria (PGPR) in crops. We have used a pangenome-based approach, based on publicly available genomes, to apply whole genome multilocus sequence type schemes to assess whether there is an association between source and genotype, aiming at differentiating between isolates from nosocomial sources and the environment, and between strains reported as PGPR from other environmental strains. Most genomes from a nosocomial setting and environmental origin could be assigned to the proposed nosocomial or environmental MLSTs, which is indicative of an association between source and genotype.

In vitro activity of apramycin against multidrug-, carbapenem- and aminoglycoside-resistant Enterobacteriaceae and Acinetobacter baumannii.

J Antimicrob Chemother 2019 Jan 9. Epub 2019 Jan 9.

Institute of Medical Microbiology, University of Zürich, Gloriastrasse 30, CH-8006 Zürich, Switzerland.

Objectives: Widespread antimicrobial resistance often limits the availability of therapeutic options to only a few last-resort drugs that are themselves challenged by emerging resistance and adverse side effects. Apramycin, an aminoglycoside antibiotic, has a unique chemical structure that evades almost all resistance mechanisms including the RNA methyltransferases frequently encountered in carbapenemase-producing clinical isolates. This study evaluates the in vitro activity of apramycin against multidrug-, carbapenem- and aminoglycoside-resistant Enterobacteriaceae and Acinetobacter baumannii, and provides a rationale for its superior antibacterial activity in the presence of aminoglycoside resistance determinants.

Case Rep Infect Dis 2018 19;2018:5903589. Epub 2018 Nov 19.

Department of Medicine, Lewis Katz School of Medicine at Temple University, Philadelphia, USA.

While bacteremia due to is not uncommon, it rarely causes infective endocarditis. We report an isolated case of a 53-year-old male with history of intravenous drug abuse who presented with multiple acute pain symptoms and was found to have bacteremia with septic emboli in his spleen, brain, and testes, secondary to a large aortic vegetation, as well as aortic infective endocarditis with severe aortic regurgitation requiring aortic valve replacement. His course of disease was further complicated by epidural and psoas abscesses and a necrotic testicle requiring orchiectomy due to his ongoing intravenous drug abuse. Read More

The propagation of active-passive interfaces in bacterial swarms.

Nat Commun 2018 12 18;9(1):5373. Epub 2018 Dec 18.

Department of Mechanical Engineering & Applied Mechanics, University of Pennsylvania, Philadelphia, PA, 19104, USA.

Propagating interfaces are ubiquitous in nature, underlying instabilities and pattern formation in biology and material science. Physical principles governing interface growth are well understood in passive settings; however, our understanding of interfaces in active systems is still in its infancy. Here, we study the evolution of an active-passive interface using a model active matter system, bacterial swarms. Read More

Protealysin Is Not Secreted Constitutively.

Protein Pept Lett 2018 Dec 11. Epub 2018 Dec 11.

Institute of Molecular Genetics, Russian Academy of Science, Moscow. Russian Federation.

Protealysin, a zinc metalloprotease of Serratia proteamaculans, is the prototype of a new group within the peptidase family M4. Protealysin-like proteases (PLPs) are widely spread in bacteria but are also found in fungi and archaea. The biological functions of PLPs have not been well studied, but published data showed the involvement of enzymes of this group in the interaction of bacteria with higher organisms, and most likely in the pathogenesis.

[Surveillance of resistance in the intensive care units using a cumulative antibiogram].

Mikrobiyol Bul 2018 Oct;52(4):329-339

Haydarpaşa Numune Training and Research Hospital, Department of Medical Microbiology, Istanbul, Turkey.

Empiric treatment with broad-spectrum antibiotics exerts condensed pressure in intensive care units (ICUs) for the selection of multidrug-resistant bacteria. Multidrug-resistant gram-negative bacteria became the focus of interest owing to limited treatment options and negative effects on patient survival. Cumulative antibiograms can guide selection of correct empiric treatment, de-escalation treatment according to antibiogram results and development of policies in fight against antibiotic resistance.

High-Temperature Short-Time Treatment of Human Milk for Bacterial Count Reduction.

Front Pediatr 2018 27;6:359. Epub 2018 Nov 27.

Center for Pediatrics, Department of Neonatology, Faculty of Medicine, Medical Center - University of Freiburg, Freiburg, Germany.

Human milk (HM) for preterm infants will often be pasteurized for cytomegalovirus (CMV) inactivation and reduction of its bacterial count. High-temperature short-time (HTST) treatment compared to standard Holder pasteurization (HoP) reduces the impact of heat treatment on bioactive HM proteins while effectively inactivating CMV. No data are available for the efficacy of bacterial count reduction using HTST treatments that are available for clinical use. Read More

Comparative Analysis of Anuran Amphibian Skin Microbiomes Across Inland and Coastal Wetlands.

Microb Ecol 2018 Dec 8. Epub 2018 Dec 8.

Department of Biology, East Carolina University, Greenville, NC, USA.

Amphibians host a community of microbes on their skin that helps resist infectious disease via the dual influence of anti-pathogenic microbial species and emergent community dynamics. Many frogs rely on freshwater habitats, but salinization is rapidly increasing saltwater concentrations in wetlands around the globe, increasing the likelihood that frogs will come into contact with salt-contaminated habitats. Currently, we know little about how increased salt exposure will affect the symbiotic relationship between the skin microbes and frog hosts. Read More
