Entomophthora coronata in tissue. Splendore-Hoeppli effect. H & E stain (450X) Read More
Saints preserve us from this one. A highly contagious hemorrhagic fever, Marburg is less well known that it's cousin Ebola, (they're both members of the deeply troublesome Filovirus family) but no less deadly.
Under a magnification of 200x, and using a lactophenol cotton blue mount fixation technique, this photomicrograph reveals some of the ultrastructural morphology exhibited by a Mucor sp. fungal organism. This image depicts two sporangia, a mature structure, which had ruptured, releasing its conte... Read More
Scanning Electron Micrograph of Burkholderia cepacia.
Burkholderia cepacia is the name for a group or “complex” of bacteria that can be found in soil and water. B. cepacia bacteria are often resistant to common antibiotics.
B. cepacia poses little medical risk to healthy people. However,... Read More

Simple crystal violet stained preparation mainly consisting of B. subtilis spores with a few scattered rods. Taken from the Wistreich Collection, appearing exclusively on MicrobeWorld. Read More
Magnified 1125X, this photomicrograph revealed some of the ultrastructural morphology displayed by the dematiaceous (pigmented) filamentous fungus, Phialophora richardsiae.
Note the septate hyphae from which sprout the short conidiophores, and still further distally one can see the flask-shap... Read More
This color-enhanced photomicrograph shows different species of bacteria that cause dental plaque - a colorless film that forms on teeth caused by the growth of bacterial colonies. Plaque develops naturally, and in most cases can be easily removed with regular brushing. However, if left it can ha... Read More
Marburg hemorrhagic fever (Marburg HF) is a rare, severe type of hemorrhagic fever which affects both humans and non-human primates. Caused by a genetically unique zoonotic (that is, animal-borne) RNA virus of the filovirus family, its recognition led to the creation of this virus family. The fi... Read More

The bacterium, Enterococcus faecalis, which lives in the human gut, is just one type of microbe that will be studied as part of NIH's Human Microbiome Project. Read More
throat culture on blood agar and tellurite medium. black colonies on tellurite medium are Corynebacterium diphtheriae Read More
Subglacial outflow from the Taylor Glacier in the McMurdo Dry Valleys, Antarctica. Iron and salt precipitates form where subglacial brine flows from the Taylor Glacier, lending a bright red color to the glacier snout, which is commonly referred to as Blood Falls. The episodic release of subglaci... Read More

Paracoccidioides brasiliensis. Tissue form grown in vitro at 37C Read More
This is an interesting image I found on Flickr. The shiny yellowish/green stuff is e.coli. It is growing on media and from a urine culture. 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
H and E Stained lung sections of patient from whom the Legionella pneumophilia was isolated, showing inter-alveolar exudation of macrophages and poly-morphic leukocytes. Legionella pneumophilia is not stained Read More
