The TWiPniks docs solve the case of the Female from Peru with Epistaxis, and discuss the effect of community deworming on immunosuppression.
Diphtheria an infection caused by Corynebacterium diphtheriae can be fatal at times, especially if it involves the respiratory tract. They multiply locally on mucous membrane, produce toxin causing necrosis of epithelial cells and ultimately form pseudomembranous coat. These pseudomembrane may ... Read More
Venezuelan equine encephalitis virus (VEEV) is an unforgiving killer of horses, donkeys and zebras, resulting in mortality as high as 80 percent of infected animals. It causes rapid, catastrophic swelling of the brain and spinal cord, leading to severe neurological symptoms and—in many cases—sud... 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
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
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
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
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
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
