Cylindrospermopsis (sill-in-dro-sperm-op-sis) raciborskii, a blue green alga (cyanobacterium) in which the terminal cell of the trichome (filament) appears a bit like a candle flame.

Several filaments of a blue green alga that does not form heterocysts. This image taken after most of the water had dried out and illustrates how microbes may survive in very very thin films of water (in this case only a few microns thick). Differential intereference contrast optics.

Anabaena, one of the filamentous blue green alga which can form heterocysts. Single filaments are attached to the substrate and occur within an irregular mucus sheath which acquires metal salts to become brown in colour. Heterocysts are spherical, more hyaline, slightly larger than other cells and are a site for enhanced nitrogen fixation. Differential interference contrast.

Venenivibrio stagnispumantis strain CP.B2 is the first microorganism isolated from the terrestrial hot spring Champagne Pool (75 °C, pH 5.5) in Waiotapu, New Zealand. The cells are motile, slightly curved rods measuring 1.04 to 1.56 μm in length and 0.33 to 0.41 μm in width.

Chroococcus minutus Scale bar indicates 10 µm. Collected from a pond near Lemkendorf, isle of Fehmarn (Baltic Sea). The image was built up using several photomicrographic frames with manual stacking technique. The images were taken using Zeiss Axioplan with Canon EOS 70D.

This highly magnified electron micrograph depicted numbers of Staphylococcus aureus bacteria, which were fond on the luminal surface of an indwelling catheter. Of importance is the sticky-looking substance woven between the round cocci bacteria, which was composed of polysaccharides, and is known as biofilm. This biofilm has been found to protect the bacteria that secrete the substance from attacks by antimicrobial agents such as antibiotics; Magnified 2363x.
S. aureus, often referred to simply as "staph," are bacteria commonly carried on the skin, or in the nose of healthy people. Approximately 25% to 30% of the population is colonized, i.e., when bacteria are present, but not causing an infection, in the nose with staph bacteria.

This photomicrograph reveals McCoy cell monolayers with Chlamydia trachomatis inclusion bodies; Magnified 200X. Chlamydia, caused by Chlamydia trachomatis, is the most common bacterial sexually transmitted infection. Using cell cultures from the McCoy cell line is one methods implemented in diagnosing Chlamydial infections. Date: 1975.
