New infectious diseases emerge with worrisome frequency. Some accompany natural events such as changes in climate, while others surface with human help. Of great importance among the latter are the infections caused by Clostridium difficile (casually called C. diff). The prevalence of these infe... Read More
Analysis of all complete genome sequences of the pandemic influenza A(H1N1)v virus available as of 10 September 2009 revealed that two closely related but distinct clusters were circulating in most of the affected countries at the same time. The characteristic differences are located in genes en... Read More

Archaeans are single-celled creatures that join bacteria to make up a category of life called the Prokaryotes (pro-carry-oats). Prokaryotes' genetic material, or DNA, is not enclosed in a central cellular compartment called the nucleus. Bacteria and archaea are the only prokaryotes. ... Read More
Greetings Vincent and Dick,
Hooray for finally mentioning G. pulchrum in episode 62, my most favorite parasite and one worthy of further discussion. As a diagnostic veterinary pathologist, I encounter this spirurid in approximately... Read More

Fun science activity for kids!
Have you ever wondered how scientists extract DNA from an organism? All living organisms have DNA, which is short for deoxyribonucleic acid; it is basically the blueprint for everything that happens inside an organism’s cells. Overall, DNA tells an organism how ... Read More
Howard Goldfine, Professor of Microbiology at the University of Pennsylvania School of Medicine, has authored a new post on Small Things Considered that looks at the interesting evolution of plasmalogens from anaerobes to plant and animal cells.
"Plasmalogens appeared early, but did not survi... Read More
This is the third annual Week of the Fungi on Small Things Considered, a sporadic undertaking (please excuse the pun).
"Sooner or later, but usually sooner, anyone dealing with fungi will have to deal with the issue of spore dispersal. Many fungi, mushrooms included, are a spore’s way of spre... Read More
