Helicobacter pylori (yellow), a common bacterium that lives in the stomach lining, increases the risk of stomach cancer (brown cells) and peptic ulcers. But over time H. pylori can reduce stomach acid and acid reflux, which may help fend off esophageal cancer. The microbe also appears to help pr... Read More
The foreground shows the density map (gold) from a cryoelectron micrographic reconstruction of malabaricus grouper nervous necrosis virus, a fish nodavirus. The background shows the fitting of a two-domain model consisting of a protruding domain and a β-sandwich domain into the reconstruction de... Read More

This digitally-colorized scanning electron micrograph (SEM) depicted a small grouping of Gram-negative Sebaldella termitidis bacteria.
Recently, “the genome of ATCC 33386 S. termitidis was recently sequenced as part of the U.S. Department of Energy - Joint Genome Institute’s (DOE-JGI) Genomic E... Read More

Researchers have discovered the largest virus ever, and they've given it a terrifying name: Pandoravirus.
A typical virus is a tiny sack of genetic material that injects itself into a much larger cell and uses it to make more viruses. The Pandoravirus is enormous by comparison—large enough to... Read More
The bug lives harmlessly in the noses of about a third of us. But it can turn rogue, causing skin infections—or worse. Heavy use of antibiotics since the middle of the last century has prompted the evolution of deadly superbug strains. Photograph by Martin Oeggerli, with support from School of L... Read More

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
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
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
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
