Giardia protozoan

This digitally-colorized scanning electron micrograph (SEM) depicted the dorsal (upper) surface of a Giardia protozoan that had been isolated from a rat’s intestine. Some of the identifying morphologic characteristics include pairs of thread-like flagella that facilitate motility, and a ventolat... Read More

Dangerous Rendezvous

A macrophage (pale brown) interacts with Borrelia cells (blue), the spirochete bacteria that cause Lyme disease. Although the outer membrane of Borrelia contains a strong antigen, the OspC protein, the bacterium successfully evades the human immune system by hiding out in places less accessible ... Read More

C. elegans sex-cell division

This montage of tiny, transparent C. elegans—or roundworms—may offer insight into understanding human infertility. Researchers used fluorescent dyes to label the worm cells and watch the process of sex-cell division, called meiosis, unfold as nuclei (blue) move through the tube-like gonads. Such... Read More

Marine bioluminescent Photobacterium kishitanii

Marine bioluminescent Photobacterium kishitanii
The genus Photobacterium was first coined by Martin Beijerinck, in 1889, and originally referred to all bacteria capable of light production. Species belonging to Photobacterium are gram negative, rod shaped, chemoorganotrophic, facultative aerob... Read More

Photos from the ASMBiodefense 2012 H5N1 Research Discussion

Moderated by the Chair of the National Science Advisory Board for Biosecurity (NSABB), Paul Keim, Ph.D., this session at the ASM Biodefense and Emerging Diseases Research Meeting included discussions of the NSABB’s recommendations for the publication of the controversial H5N1 research.

-Important Ingredients: crystal violet, bile salts, neutral red (color indicator), lactose
-Differential: used to identify and isolate lactose fermenting G- enteric bacteria mainly Enterobacteriaceae. Strong lactose fermentation pr... Read More

H1N1

This highly-magnified, digitally-colorized transmission electron micrograph (TEM) depicted numbers of virions from a Novel Flu H1N1 isolate. Thanks to the CDC's PHIL for this image. 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

Behind the scenes: TWiV 200 at the NEIDL

We celebrated the 200th episode of TWiV by visiting the National Emerging Infectious Diseases Laboratories at Boston University Medical Center, where we met with Elke, Paul, and Ron to talk about building and working in a BSL4 facility. It was an amazing visit that will be fully documented in an... Read More

Confocal micrograph showing Shigella bacteria invading the intestinal lining.

Confocal micrograph showing Shigella bacteria (pink) invading the intestinal lining. The bacteria infects the cells by high-jacking the cell's internal actin skeleton (green) to facilitate its entry into the cell and spread into adjoining cells, using polymerizing actin comet tails as several ca...

Bacteria biofilm

This confocal micrograph, taken as part of a synthetic biology project, shows Bacillus subtilis, a Gram-positive, rod-shaped bacterium that is commonly found in soil. Distinct lineages of bacteria expressing different fluorescent proteins were initially mixed randomly on a petri dish. As the bac... Read More

Introducing the Thanatomicrobiome

In a healthy adult human body, most internal organs such as the brain, spleen, liver, and heart are devoid of microorganisms because the immune system keeps them in check. After human host death, however, the immune system falters and microorganisms proliferate throughout the body beginning in ... Read More
