Bacteria from a human beard. Colored scanning electron micrograph (SEM) of bacteria cultured from a human beard. A European study has found that the average man's beard is more replete with human-pathogenic bacteria than the dirtiest part of a dog's fur. There are around 1000 species of bacteria from 19 phyla found on human skin. Skin flora is usually non-pathogenic, and either commensal (not harmful to their host) or mutualistic (offer a benefit).

Stomach lining. Colored scanning electron micrograph (SEM) of the glandular lining (mucosa) of the stomach. The gastric mucosa secretes the digestive enzymes and hydrochloric acid. This surface epithelium of simple columnar cells secretes mucus, while the gastric glands are the pits seen in this epithelium. From these pits digestive enzymes are produced. Thousands of these glands line the stomach wall. On the larger scale, the stomach mechanically churns food around, while on this scale, gastric juices act to chemically break down the food. This thick lining and large amounts of mucus protect the stomach from these digestive processes. Magnification: x800 when printed at 10cm wide.Stomach lining.

Acanthocystis. Colored scanning electron micrograph (SEM) of a centrohelid heliozoan with tangential plate-scales and radial spines. This genus Acanthocystis contains unicellular, free-floating planktonic or benthonic living organisms which are common in freshwater but also found more rarely in marine habitats. The evolutionary position of the centrohelids is not clear. Magnification: x 2500, when printed 10 centimeters wide.Acanthocystis.

Small intestine. Colored scanning electron micrograph (SEM) of a freeze-fractured of the small intestine. The surface consists of deep folds, called villi. The intestinal surface( pink) is exposed to food. The underlying structure of this surface is seen in the sectioned area. Surface (epithelial) cells (blue) are supported by connective tissue (red) that forms the core of each fold (villus). This central core of connective tissue is known as the lamina propria. This contains large blood vessels, capillaries, some smooth muscle cells and a blind- ended lymph vessel known as a lacteal. The folds increase the area for the absorption of nutrients from food. The height of a villus varies in a small intestine from 0.3 to 0.8 millimetres. Magnification: x800 when printed at 10 centimeters wide.Small intestine.

Bacteria from a coin. Colored scanning electron micrograph (SEM) of bacteria cultured from a english one pound coin. A study that tested a random selection of coins and notes of all denominations discovered the presence of 19 kinds of bacteria, including two life threatening bacteria associated with antibiotic resistant superbugs - Staphylococcus aureus (MRSA) and Enterococcus faecium (VRE). Bacteria associated with MRSA was discovered on the 2p, 5p, 10p, �1 and �2 coins, as well as the �10, �20 and �50 notes. MRSA can lead to boils, skin infections, food poisoning and toxic shock syndrome. The bacteria Enterococcus faecium was found on the 2p, 5p and 10p coins as well as the �10 note. This bacteria can cause blood, abdomen, skin and urinary tract infections. Magnification: x2600 when printed at 10cm wide.Bacteria from a coin.

Cannabis plant. Colored scanning electron micrograph (SEM) of the surface of a cannabis (Cannabis sativa) plant. The pointed hairs are called lithocyst cells. They contain cystoliths (calcium carbonate crystals). Glandular cells called trichomes are also present. These are capitate trichomes that have stalks. These trichomes secrete a resin (yellow) containing tetrahydrocannabinol, the active component of cannabis when used as a drug. Magnification: 220X when printed 10 cm wide.Cannabis plant.

Human lip. Colored scanning electron micrograph (SEM) of a human lip, showing sweat gland openings on the drier external lip surface. These openings (pores) release sweat onto the surface of the skin. This has the effect of cooling the body, as the sweat's evaporation carries away heat.

Staphylococcus aureus (MRSA) coccoid bacteria, colored scanning electron micrograph (SEM). Group dividing and stuck together with mucilage. Staphylococcus aureus - Gram-positive, MRSA, coccus prokaryote (dividing); causes food poisoning, toxic shock syndrome and skin and wound infections such as scalded skin syndrome, scarlet fever, erysipelas and impetigo. Methicillin resistant Staphylococcus aureus (MRSA) infections that are acquired by persons who have not been recently hospitalized or had a medical procedure are known as CA-MRSA (Community associated-MRSA) infections. CA-MRSA infections in the community are usually manifested as skin infections, such as pimples and boils, and occur in otherwise healthy people.

Breast cancer cells. Colored scanning electron micrograph (SEM) of breast cancer cells. The cells shows numerous processes and micro plicae (fine surface folds). These features are characteristic of highly mobile cells, and enable cancerous cells to spread (metastasis) rapidly round the body, and invade other organs and tissues. Cancer cells divide rapidly and chaotically, and may clump to form malignant tumors. The tumors often invade and destroy surrounding tissues. Breast cancer is the most common form of cancer in women. Treatment involves surgical removal of the tumor, often combined with radiotherapy and chemotherapy. Magnification: x3500 when printed 10cm wide.Breast cancer cells.
