Clip 4) Cryptomonas cryptomonads. Light microscopy footage of several Cryptomonas cryptomonads in a water sample. Cryptomonads are unicellular microscopic organisms that can have characteristics of both protozoa and algae. Cryptomonas is oval in shape, has two flagella, and obtains energy by photosynthesis. These specimens are in a freshwater sample from South Korea.

Helicobacter pylori... the bacteria is one of the main causes of gastric ulcers.

This bacteria was first detected in the early 1980's by Australian scientists Barry Marshall and Robin Warren as a causative agent of chronic gastritis and gastric ulcers. H. pylori populates the mucosa of the human stomach exclusively. The bacterium drills through the mucus layer and attaches to the stomach epithelial cells. It is diagnosed by a stomach biopsy or a Urea Breath Test. Formerly known as Campylobacter pyloridis, this Gram-negative spiral-shaped bacterium uses flagella (hair-like strands) for locomotion. It may also be a cause or co-factor for gastric cancer as its presence increases the risk of developing stomach tumors

Penicillium Mold

SEM of Penicillium chrysogenum (aka P. notatum), a species of fungus in the genus Penicillium. It is common in temperate and subtropical regions and can be found on salted food products, but it is mostly found in indoor environments, especially in damp or water-damaged buildings. It has rarely been reported as a cause of human disease. It is the source of several β-lactam antibiotics, most significantly penicillin.

Soil Bacteria

Scanning electron micrograph (SEM) of bacteria in the soil. They are directly tied to nutrient recycling especially carbon, nitrogen, phosphorus and sulfur. Bacteria are a major class of microorganisms that keep soils healthy and productive. A teaspoon of productive soil generally contains between one hundred million and one billion bacteria. That is as much mass as two cows per acre. A ton of bacteria may be active in each acre. Bacteria make up both the largest number and biomass (weight) of any soil microorganism.

Lymph Node Blood Vessels

Color enhanced scanning electron micrograph (SEM) of a resin cast of blood vessels in a lymph node. This network of vessels infiltrates the tissue, supplying it with blood. Gases and nutrients are exchanged between the blood and surrounding tissue through the permeable walls of capillaries, the smallest blood vessels. The cast was made by injecting resin into the blood vessels and then chemically digesting the surrounding tissues.

It's that time of year again... Tick Season!

Be careful out there and be sure to check yourself for ticks after hiking or walking in tall grass.

Tick feeding on human blood. Color enhanced scanning electron micrograph (SEM) of a tick (Ixodes sp.) with its mouth parts buried in the skin of its human host while feeding on its blood. The legs are protruding from its body either side of the point at which the tick is embedded in the skin. These types of ticks are characterized by a shield-like plate (brown, left) on the back of the body. Ticks are vectors for a number of diseases caused by bacteria or viruses, including Lyme disease, tick-borne encephalitis (TBE) tick typhus and Colorado tick fever.

Clip 2) Time-lapse light microscopy footage of bacterial phagocytosis by macrophages. Macrophages are cells of the body's immune system. They phagocytose and destroy pathogens, dead cells and cellular debris. Here, the macrophages (larger objects) are engulfing the bacteria (smaller, dark blue rods), a process known as phagocytosis.
