    Legionella - pathogenic Gram negative bacterium. Acquired its name after a July, 1976 outbreak of a then-unknown "mystery disease" sickened 221 persons, causing 34 deaths. The outbreak was first noticed among people attending a convention of the American Legion - an association of U.S. military veterans

    Neuron cell body (purple) with numerous synapses (blue). Communication from one neuron flows to another neuron across a synapse, the small gap separating neurons. SEM X80,000.

    Salmonella Bacteria - These guys cause a lot of disease including the most well known typhoid fever...

    Macrophage engulfing bacteria as part of the immune system's response to infection. SEM X9000

    Nerve bundle. Coloured scanning electron micrograph (SEM) of a freeze-fractured section through a bundle of myelinated nerve fibres. Myelin sheaths (yellow) can be seen surrounding the axons (blue). Perineurium (connective tissue, pink) surrounds the nerve bundle while endoneurium divides the individual fibres.

    "The Lone Ranger"- Kupffer cell (specialized macrophage, green) patrolling the tiny vessels in the liver called sinusoids, where they recycle old red blood cells and ingest pathogens. The endothelium (reddish pink) of these vessels has large holes, allowing the Kupffer cells to migrate into the liver tissue at sites of damage and inflammation.

    A wound. Red blood cells, neutrophils, macrophages and mast cells.

    Bone marrow stem cell, SEM

    Lung cancer cell (imaged using a scanning electron microscope [SEM])

    In this electron micrograph, a human white blood cell is trapping bacterial cells. This type of cell defends the body against pathogens and other harmful particles by engulfing foreign objects and destroying them with the help of enzymes from the cell's lysosomes.

    An invading cell (orange) is surrounded by macrophages (blue) whose function is to engulf and digest foreign cells

    Staphylococcus aureus bacteria. Colored SEM of Staph aureus bacteria (yellow) on human nasal epithelial cells.

    Coloured scanning electron micrograph of the spirochaete bacterium Borrelia burgdorferi, the cause of lyme disease in humans. The spiral-shaped bacteria are passed on to humans via tick bites. Magnification: x3650

    Blood clot. Coloured scanning electron micrograph (SEM) of a blood clot from the inner wall of the left ventricle of a human heart.

    Staphylococcus sp. Coloured scanning electron micrograph (SEM) of a colony of Staphylococcus sp. bacteria on the epithelial cells of the trachea. The trachea (windpipe) is lined with cilia (hair- like projections) which help keep it free of dust and other irritants. These Gram-positive bacteria often appear in groups that resemble clusters of grapes (as here)

    Scanning electron micrograph of "Bacillus anthraces," commonly known as anthrax. "These rod-shaped, Gram-positive, spore-forming bacteria can infect the skin (cutaneous anthrax), causing raised itchy lesions, the lungs (pulmonary anthrax), which is fatal unless treated quickly, and the digestive system (gastrointestinal anthrax), causing vomiting of blood and severe diarrhoea. All forms can be fatal if left untreated."

    Hayfever sufferers can now see the face of their invisible enemy - thanks to these amazing microscopic pollen pictures. A Swiss scientists named Martin Oeggerli, who uses the name Micronaut for his art, has captured these Scanning Electron Microscope images of pollen grains.
