Smallpox is a serious, highly contagious, and sometimes fatal infectious viral disease. There is no specific treatment for smallpox disease, and the only prevention is a smallpox vaccination. Read More
Three organisms inoculated in TSB to look at tube morphology. From left to right:
Staphylococcus aureus: flocculent growth/turbid, growth throughout the tube.
Mycobacterium smegmatis: pellicle, growth at the top of the tube. M. smegmatis tends to stick to the tube and grow up the side.
Ba... Read More
A positive D test indicates that the presence of macrolide-inducible resistance to clindamycin produced by an inducible methylase enzyme that alters the common ribosomal binding site for macrolides, clindamycin and the group B streptogrammins (quinupristin). This cross-resistance, called the ML... Read More

MRSA is bad news. If you've never heard of it, here's what you need to know: It's pronounced MER-suh, it's a nasty bacterial infection and it can cause serious disease and death. Read More
Researchers from the University of Zurich and the University Hospital Zurich reveal possible new treatment methods for a rare, usually fatal brain disease. Thanks to their discovery that specific antibodies play a key role in combating the viral infection, a vaccine against the disease "progress... Read More
ANN ARBOR, Mich. -- Like a collection of ragtag villagers fighting off an invading army, the mix of bacteria that live in our guts may band together to keep dangerous infections from taking hold, new research suggests. Read More
New research may revolutionize the slow, cumbersome and expensive process of detecting the antibodies that can help with the diagnosis of infectious and auto-immune diseases such as rheumatoid arthritis and HIV. An international team of researchers have designed and synthetized a nanometer-scale... Read More
Nitrate reduction test for the reduction of nitrate in nitrate media, to determine if the bacteria contains nitrate and/or nitrite reductase. Organism were incubated for 48 hr's at 37 degree's in nitrate media then reagents added.
Nitrate broths after the addition of 10 drops re... Read More

Philadelphia artist Kate Kaman (www.katekaman.com) has designed a dynamic larger-than-life sculptural depiction of the most plentiful and ancient microscopic life forms -- bacteria. Suspended throughout an area measuring approximately 130 feet long, 27 feet wide and 41 feet tall, “The Unseen Wor... Read More
Paenibacillus species have been isolated from a wide variety of sources including soil, water, the plant rhizosphere, plant materials, food, fodder, faeces and diseased insect larvae. They are facultative anaerobes or strict aerobes and mostly motile, endospore forming rods. This is the first ti... 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
The production of Metallo-β-lactamase is one of the resistance mechanisms of Pseudomonas aeruginosa. Metallo-β- lactamases are members of Group B in the molecular classification of Ambler and are Clavulanic acid resistant enzymes which require divalent cations of zinc as co-factors for enzymat...

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
Phytoplankton may be microscopic, but that doesn’t mean we can’t see them. Just look up: These little critters are brightening up cloudy days around the world. Read More
Young sibling polyps of staghorn coral (Acropora millepora) three days after settlement. In a National Science Foundation-supported study, researchers found that the ability to fluoresce may influence whether or not the coral settle on the reef of their origin or disperse, and go elsewhere.
