MetaPalette: a k-mer Painting Approach for Metagenomic Taxonomic Profiling and Quantification of Novel Strain Variation

Taxonomic profiling is a challenging first step when analyzing a metagenomic sample. This work presents a method that facilitates fine-scale characterization of the presence, abundance, and evolutionary relatedness of organisms present in a given sample but absent from the training database. We ... Read More

Motherboard: Your Showerhead Is Crammed Full of Bacteria That Scientists Want to Study

Scientists know very little about the kinds of bacteria that we interact with on a daily basis in our homes. Researchers from Colorado, and North Carolina are interested in what kinds of microbes are living in your shower head.

They are hoping to find out where Nontuberculous mycobacteria is... Read More

Antibiotic Resistance Appears to Persist in Bacteria, Even Absent Selection Pressure From Antibiotics

Washington, DC – August 1, 2016 – Plasmids are pieces of independent DNA that often carry multiple antibiotic resistance genes. Plasmids can jump from one bacterium to another, spreading that resistance. A team of French investigators now shows that bacteria that acquire plasmids containing res... Read More

Molecular Analysis and Expression of bap Gene in Biofilm-Forming Multi-Drug-Resistant Acinetobacter baumannii. Reports of Biochemistry & Molecular Biology 2016


Background: Acinetobacter baumannii is commonly resistant to nearly all antibiotics due to presence of antibiotic resistance genes and biofilm formation. In this study we determined the presence of certain antibiotic-resistance genes associated with biofilm production and the influen... Read More

BacterioFiles 261 - Pilfered Parasitoid Proteins Protect Prey

This episode: Viruses domesticated by parasitoid wasps have transferred wasp genes to caterpillar victims, allowing them to survive deadly infections from other viruses! This means that Monarch butterflies are effectively naturally Genetically Modified Organisms (GMOs).

The classic and current studies of bacterial endospore morphology

Recently, one of the Journal of Bacteriology Classic Spotlight series highlighted the numerous studies on bacterial spores that have been published in the journal throughout the years. Bacterial endospores, the resilient and relatively quiescent bacterial structures first identified in the 1800s... Read More

Green Monkeys Acquired Staphylococcus aureus From Humans

Washington, DC – July 29, 2016 - Many deadly diseases that afflict humans were originally acquired through contact with animals. New research published in ASM’s Applied and Environmental Microbiology shows that pathogens can also jump the species barrier to move from humans to animals. The study... Read More

WSJ: Microbial Nanowires

Researchers as the University of Massachusetts are working with Geobacter by manipulating their genetic material. This manipulation makes the bacteria produce filaments of tryptophan, increasing the electrical conductivity of the bacteria by 2,000 times.

The uses for these nanowires could be... Read More

Is it safe to go into the ocean? Standardizing molecular methods for water safety surveillance

Have you ever gone to the beach, ready for a day of sun and sand, only to find a warning sign? One of the most common reasons beaches close is due to the presence of coliform bacteria. These indicator bacteria, such as Escherichia coli, are used as markers for fecal waste, since their presence c... Read More

E. coli with pGFP expression

Streak plate of E. Coli transformed with the plasmid Green Fluorescent Protein (pGFP). Under UV light the colonies expressing GPF fluoresce green, colonies with normal light were a light green as well. Culture was grown on LB agar with ampicillin for 48 hrs. Read More

Zika Virus Vaccine

The first experimental Zika virus vaccine has been published, and in this episode of Virus Watch, I explain how it works - it's a DNA vaccine - compared with all the other vaccines out there. Read More

Paging Doctor Copper: Metal Wins Fans in Health Care

Copper is used in everything from automobiles to air conditioners, but it has one property that makes it especially attractive for medical uses: It kills bacteria.

A burgeoning opportunity for copper producers relies on a simple premise: that the base metal is good for your health.

Copper ... Read More

ASMCUE Happenings 2016

Whether lecturing a quorum of undergraduates about bacterial genetics, mentoring a research fellow as they learn the lab protocols, or presenting an invited lec... Read More

Long Read: How Miraculous Microbes Help Us Evolve Better, Faster, Stronger

Smithsonian.com delves into the weeds of horizontal gene transfers (HGT) in bacteria. A feat that is largely unique to bacteria, it allows bacteria to trade DNA with other bacteria.

Bacteria can "exchange DNA as easily as we might exchange phone numbers, money or ideas".

Explore some of ... Read More

Science Magazine: New antibiotic found in human nose

With drug-resistant bacteria on the rise, scientists believe the nose is engaging in "microbial warfare". Scientists in Germany have identified that Staphylococcus lugdunensis, found in the nose, excretes a compound they named lugdunin. This compound prevents S. aureus from growing. S. aureus ca...

Two birds with one stone: E. faecium cotransfers drug resistance determinants by homologous recombination

The Gram-positive bacterium Enterococcus faecium is a member of the ESKAPE pathogens for which drug resistance has been a growing problem. How E. faecium becomes drug resistant has been a long-standing question, and is the focus of a new study now available in Antimicrobial Agents and Chemothera... Read More
