RFKG56HW–Mechanism of indirect immunofluorescence test, computer illustration. Immunofluorescence is a cell imaging technique based on the use of antibodies to label a specific target antigen (bacteria, cancer cells, other) with a fluorescent dye (also called fluorophore or fluorochrome). The fluorescent dye allows visualization of the antigen distribution in the sample under a fluorescent microscope. Indirect immunofluorescence uses two antibodies, the primary and the secondary.

RFHN2KJX–Stomach mucosa. Light micrograph (bottom left) and computer illustration (top right) of the lining of the stomach, known as the mucosa. The stomach is a muscular sac involved in storage and digestion of food. The surface of the mucosa consists of simple columnar cells (dark purple in micrograph) that secrete mucus. The mucus protects the stomach lining from digestive acids and enzymes that act on food in the stomach. Beneath the columnar cells are gastric pits, the glands that make the acids and enzymes needed to digest food.

RF2C4G08R–Testicular cancer, a malignant spermatocytic seminoma, computer illustration and light micrograph. A seminoma is a malignant tumour (cancer) of the testis (testicle). Although this is a rare cancer, it is the most common cancer in 15 to 35 year old men. It arises from abnormal germ cells (precursors to sperm cells) in the seminiferous tubules. Surgical removal of the affected testis (orchidectomy) is followed by radiotherapy and chemotherapy if required.

RFM5HWHT–Chlamydia psittaci bacteria. Computer illustration showing two life stages of Chlamydia: elementary bodies (extracellular non-multiplying infectious stage, small orange spheres outside the cell) and an inclusion composed of a group of chlamydia reticulate bodies (intracellular multiplying stage, small orange spheres inside the cel) near the nucleus (violet) of a cell. Chlamydia species are atypical bacteria in that they are obligate intracellular parasites, living and reproducing only inside cells. This species causes abortion in animals and lung disease in humans.
