Yellow Unknown Yeast

Unknown yeast isolated on TSA from a swab taken from the bottom of a shoe incubated at 25 degrees C. Yellow, mucoid, round colonies were seen after 2 weeks. This isolate grew equally well at 37 degree C with a growth time of ~ 1 week. Read More

Malaria's key to the liver uncovered

Scientists uncover a port of liver entry for malaria parasites in a report published in The Journal of Experimental Medicine. If these results hold up in humans, drugs that target this entry protein might help prevent the spread of disease. Read More

HIV cure research: NIH scientists create 2-headed protein to deplete HIV reservoir

Scientists at the National Institutes of Health (NIH) have created a protein that awakens resting immune cells infected with HIV and facilitates their destruction in laboratory studies. The protein potentially could contribute to a cure for HIV infection by helping deplete the reservoir of long-... Read More

Portraits of Microbiologists Using Luminous Bacteria as "Paint."

My wife Jennifer Quinn​ hits it out the park: a portrait of Kenneth Nealson​ and the late Woody Hastings "painted" with luminous bacteria, giving them props for the early days of quorum sensing---where the basic principles were first uncovered in bioluminescent microbes. This principle of "aut... Read More

Echinococcus granulosus

This is a picture of Echinococcus granulosus from an infected liver specimen recently received in our laboratory. It is pictured in a saline wet mount at 40X magnification. The picture shows an evaginated scolex from an immature worm with hooklets.

The adult worm of Echinococcus granulosus l... Read More

Marburg virus virion

This colorized negative stained transmission electron micrograph (TEM), captured by F.A. Murphy in 1968, depicts a Marburg virus virion, which had been grown in an environment of tissue culture cells. Marburg hemorrhagic fever is a rare, severe type of hemorrhagic fever which affects both humans... Read More
