A new study at The University of Texas Medical Branch in Galveston sheds light on how Ebola so effectively disables the human immune system.
Virologist Alex Bukreyev, UTMB professor and senior author of the study, said the research team engineered versions of the Ebola virus in order to study... Read More
Every 18 seconds someone dies from tuberculosis - it is the world’s most deadly infectious disease.
Mycobacterium tuberculosis, the causative agent of tuberculosis (TB), has infected more than one-third of the human population with an annual death toll of approximately 1.5 million people.

Actinobacteria are the bacterial phylum responsible for production of many clinically-relevant antibacterial compounds. Streptomyces is a soil-dwelling genus of actinobacteria that produces drugs like neomycin and chloramphenicol. Despite deriving many antibiotics already from Streptomyces, coul... Read More
Contaminant (yeast?) found on TSA after several months in the refrigerator. The larger colony was circular, mat with concentric rings with a smaller more mucoid yellow growth just off center. Read More
Today was the last day of my microbiology course at the University of Puget Sound. So I thought it appropriate for students to tell me the single "coolest" thing they learned in my course. Read More
The TWiPniks docs solve the case of the Female from Peru with Epistaxis, and discuss the effect of community deworming on immunosuppression.
I am talking here specifically about automation of the bacterial culture process, using Kiestra TLA (installed in my own lab early 2016), Copan WASP, etc. A useful bullet point summary for those who are considering a business case for their own laboratory. Read More
Close up of a single colony or an unknown contaminant (yeast?) on BEA agar after 1 month in the refrigerator. Looks like there was moisture on the plate as the colonies grew in a drip like pattern. Colonies were mucoid salmon red in color with yellow pin point circular growths growing in through... Read More
Unknown contaminant (yeast?) on BEA agar after 1 month in the refrigerator. Looks like there was moisture on the plate as the colonies grew in a drip like pattern. Colonies were mucoid salmon red in color with yellow pin point circular growths growing in through out. The edges of the colonies... Read More
Colonies of a green fungal contaminant, presumable airborne, on BEA agar after 1 month in the refrigerator. Green spore formation can be seen throughout the circular colonies. Read More
Fungal like contaminant, presumably air borne, on BEA media after 1 month in the refrigerator. Mucoid mounding beige center with a hairlike circular border. Read More
Over the last few decades, an age-old infectious disease has been re-emerging globally: Syphilis. Using techniques to analyze low levels of DNA, an international research team headed by the University of Zurich has now shown that all syphilis strains from modern patient samples share a common an...

A California state senator introduced a bill on Monday that would mandate reporting of antibiotic-resistant infections and deaths and require doctors to record the infections on death certificates when they are a cause of death.
The legislation also aims to establish the nation’s most compreh... Read More
Researchers from Massachusetts General Hospital (MGH) and the University of California, Riverside, have shown for the first time that RNA interference (RNAi) – an antiviral mechanism known to be used by plants and lower organisms – is active in the response of human cells to some important virus...

An analysis of 2,000-year-old human remains from several regions across the Italian peninsula has confirmed the presence of malaria during the Roman Empire, addressing a longstanding debate about its pervasiveness in this ancient civilization.
The answer is in mitochondrial genomic evidence o... Read More
A team of researchers led by Yoshihiro Kawaoka, professor of pathobiological sciences at the University of Wisconsin–Madison School of Veterinary Medicine, has developed technology that could improve the production of vaccines that protect people from influenza B.
That technology is an influe... Read More
Are we, as microbiologists, getting too clever? Is our increasing theoretical knowledge actually hindering us in our goal of effective and realistic antimicrobial stewardship? Read this article to find out more! Read More
If you are currently a microbiologist, chances are your introductory microbiology lab course syllabus hadn’t changed for decades. The course likely culminated in each student receiving an unknown bacterial sample, the identity of which was uncovered by applying techniques learned during the seme... Read More
Washington, DC – December 5, 2016 – Carbapenems are one of the most important classes of antibiotics used in humans, and are an important agent against multi-drug resistant bacteria. Now, for the first time, bacteria that carry a transmissible carbapenem resistance gene have been found in agricu... Read More
