It’s hard to turn on the news at the moment and not hear about the latest emerging disease, Zika. The filovirus joins a cadre of infectious diseases spread by arthropod vectors – meaning the disease is passed between infected individuals via insect bites. A long list of microbes are spread this ... Read More
The TWiPyzoites solve the case of the Uncommon Parasite, and discuss the role of eosinophils in promoting the growth of Trichinella in skeletal muscle.

This upcoming Monday, Chipotle restaurants across the country will close as its employees discuss food safety and safe food handling. The restaurant was in the news throughout the last half of 2015, beginning with an outbreak of E. coli in Seattle (which was kept secret!), followed by another E.... Read More
Feeling under the weather? Are you congested, maybe having a hard time breathing, especially at night? Don’t worry – this is your body’s natural response to an infection. Mucus production is generally regarded as antimicrobial – it traps particles like virions before they can infect nearby host ... Read More
Can Zika virus be sexually transmitted? Perhaps in very rare cases, but the main mode of transmission is certainly via mosquitoes. That’s why I’ve shamelessly stolen a quote on this topic from Dr. William Schaffner of Vanderbilt University: Mosquito transmission is the highway, whereas sexual tr... Read More

Exposure to reactive oxygen species, exposure to ionizing radiation, exposure to UV light – all of these are dangerous because of their potential to alter DNA sequences. Changes in DNA can affect a protein coding sequence, potentially influencing its function, but changes in regulatory regions c... Read More
The rapid spread of Zika virus through the Americas, together with the association of infection with microcephaly and Guillain-Barré syndrome, have propelled this previously ignored virus into the limelight. What is this virus and where did it come from?
News headlines highlighting an outbreak of a vaccine-preventable disease often leave readers shaking their heads. These diseases – measles, chickenpox, whooping cough – could have been prevented if only the infected children had been vaccinated. Right? Well, in the case of whooping cough, the si... Read More
In this blog post, I describe how I had students create their own cartoon depicting microbiological ideas and concepts that most tickled their fancy. I did this on their final exam, and the students came up with really interesting and entertaining ideas. IT's always interesting to see what stu... Read More
Near Kisameet Bay on the central coast of British Columbia sits a deposit of clay that covers 5 acres and spans a depth up to 42 feet in places. This vast smear formed 10,000 years ago as glacial melt filled a granite basin and fine minerals silted out.
The ancient clay likely holds secrets t... Read More
Evolutionary theory predicts that pairs of chromosomes within asexual organisms will evolve independently of each other and become increasingly different over time in a phenomenon called the 'Meselson effect.' Researchers from the University of Glasgow have demonstrated the Meselson effect for t... Read More

Nitin Phadnis joins Nels and Vincent to explain how he identified a gene that is responsible for male inviability in hybrids from a cross between two species of fruit flies. Read More
The previous post mentioned the onset of antibiotic resistance as one of the scarier, if less sensationalist, outbreaks of our time. We generally discuss antibiotic resistance in medically relevant microbes (on this blog and in the news), where resistance means the ability of disease-causing mic... Read More
Drug-resistant infections are becoming one of the scariest epidemics since the advent of antibiotic discovery. Although microbes like methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Klebsiella pneumoniae, and multidrug-resistant Pseudomonas aeruginosa are responsible for... Read More
