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

While carbapenems aren’t allowed to be given to feedlot animals, other beta-lactam antibiotics are. This is a large class of drugs that includes extended-spectrum cephalosporin drugs. There is no direct line between the use of these extended-spectrum cephalosporins and selection for carbapenem r... Read More
The TWiPniks docs solve the case of the Female from Peru with Epistaxis, and discuss the effect of community deworming on immunosuppression.
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
This fungi was isolated from a Bonsai tree (Premna sp.) This isolation is part of a undergraduate research project (student: Christopher Sambolin), from the Interamerican University of Puerto Rico, San Germán Campus. Read More
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
A new commentary from Patrick McNamara and Stuart Levy cautions that the Food and Drug Administration’s ban on triclosan and 18 other biocidal chemicals that promote antibiotic resistance is only a starting point. Triclosan’s long-term impact, as well as the risks substitute chemicals may pose, ... 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.

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
Susceptibility break points are a dirty compromise between clinical, pharmacokinetic. and epidemiological break points. Because they are a necessary compromise, there will always be disagreement, and they can never be perfect. Is there a better way? Read More
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
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
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
In this blog post, I share the creative projects that my Biology 350 (Microbiology) micronauts created this semester. They range from video parodies, to prose poems, to short-short stories to sculptures and needlepoint. Enjoy! Read More
