One of the most famous pictures of the Vaadhoo Island comes from a night where dots of light seemed to float to the shore. They made the cost look like it was covered in stars.
At night, it is not uncommon for Bio-luminescent microbes called Phytoplankton to be seen along the coast, though even... Read More

Streptomycetes are a member actinomycete family. Streptomycetes are usually found in soil and are important decomposers. They are aerobic, gram-positive, filamentous rods that create branching hyphae. They also produce more than half of the world's antibiotics, and are therefore very valuable in... Read More
B. anthracis Colony Characteristics: A. Consistency sticky (tenacious). When teased with loop, colony will stand up like beaten egg white.
Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections are caused primarily by a single strain—USA300—of an evolving bacterium that has spread with “extraordinary transmissibility” throughout the United States during the past five years, according to a new study le...

This illustration depicts an Anopheles sp. mosquito transmitting sporozoites while obtaining a blood meal.
During a blood meal, a malaria-infected female Anopheles sp. mosquito inoculates its human host with sporozoites, which then infect human liver cells, where they mature into schizonts, w... Read More
Serratia marcescens can form brilliant red colonies on LB agar due to the synthesis of the secondary metabolite prodigiosin. In the Microbiology teaching lab, we had students create pigment mutants of S. marcescens and these lovely shades of pink and white were collected for analysis. Read More

This image depicts a number of what were “suspected” smallpox scab fragments, from the archives of the Virginia Historical Society (VHS).
These fragments came to light when the Museum was in the process of putting together an exhibit entitled, “Bizarre Bits”, chronicling its collection dating... Read More
This electron micrograph depicts an amoeba, Hartmannella vermiformis (orange) as it entraps a Legionella pneumophila bacterium (green) with an extended pseudopod.
After it is ingested, the Legionella pneumophila bacterium can survive as a symbiont within what then becomes its protozoan host. ... Read More

When I first saw this photomicrograph of Haemophilus influenzae via immunofluorescence, I thought of the opening days of the first Gulf War, when CNN showed wall to wall images of the bombing of Baghdad. The crude nightvision technologies available at the time rendered everything in that green/... 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
This baby seal was found on the sea ice near McMurdo Station during one of many excursions to collect soil samples for microbiological analysis. During November and December, there are many baby seals in the area. Photo taken by Hubert Staudigel from the Scripps Institution of Oceanography and... Read More
