Feeling Blue, Trypanosoma brucei

Trypanosoma brucei, a protozoan parasite, is the causative agent of African sleeping sickness in humans (T. b. gambiense and T. b. rhodesiense) and nagana in cattle (T. b. brucei). These diseases result in much economic hardship and morbidity in Sub-Saharan Africa. The life cycle of these organi... Read More

possible strongyloides

Taking pics of my dog. Recently diagnosed with Strongyloides but no better after treatment.any suggestions? Read More

Scary Movie?

Genus Serratia presents special problems of identification because of biochemical and morphological similarity to other genera of the Enterobacteriaceae, notably Klebsiella and Enterobacter. Serratia liquefaciens is an opportunistic pathogen which is capable of colonizing a wide variety of surfa... Read More

Antagonistic effect of Imipenem towards Piperacillin/tazobactam disc in Pseudomonas aeruginosa lawn on Mueller-Hinton agar

This images was taken during the lab work of my Master thesis on Metallo beta lactamase on Pseudomonas aeruginosa and Acinetobacter spps at Shree Birendra Hospital ( Army Hospital) in Kathmandu Nepal . It clearly shows the antagonism between two discs. Read More

Worm sperm motility

Two worm sperm shimmy across a microscope slide. Unlike most cells that rely on motor proteins to propel themselves forward, worm sperm use tiny fibers at their front ends. Putting the fibers together and taking them apart sets the cells in motion. In a new advance, researchers disassembled the ... Read More

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.

Presen... 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

MaConkey Agar (Mac)

Organisms grown on MacConkey Agar at 37 degrees for 24 hours.
-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

Swarm of paramecia

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
