Photomicrograph of filamentous blue-green algae, Oscillatoria species. Each band along the stand is one cell. This filament is very short probably having recently parted from a longer one. Filaments are typically many times longer. This algae is mobile, it moves and twists through the water. San Francisco Bay, California, USA. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live specimen, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.
Helicobacter pylori, previously known as Campylobacter pylori, is a gram-negative, flagellated, helical bacterium. Mutants can have a rod or curved rod shape, and these are less effective. Its helical body (from which the genus name, Helicobacter, derives) is thought to have evolved in order to penetrate the mucous lining of the stomach, helped by its flagella, and thereby establish infection.
A ball and stick model of Eicosapentaenoic Acid or EPA. It is an omega-3 polyunsaturated fatty acid. It is introduced into the diet by eating oily fish. When it comes to fat, there’s one type you don’t want to cut back on: omega-3 fatty acids. Two crucial ones - EPA and DHA - are primarily found in certain fish.
The intermembrane transporter of the Gram-negative bacterium Acinetobacter baylyi transports a lipopolysaccharide (orange) through the inner membrane consuming ATP (red)
