Photomicrograph of Chlamydia grown in culture. The sample was taken from rhesus monkey kidney cells and stained with giemsa. The cell nuclei appear red and the infective 'elementary bodies' of the Chlamydia, which develop in 'blisters' in the cells, fluoresce green. Chlamydia is a very common se... Read More
Under a magnification of 2500X, this colorized scanning electron micrograph (SEM) revealed the presence of a large number of Gram-negative Salmonella typhimurium bacteria that had been isolated from a pure culture. See PHIL 10984 for a black and white version of this image. Read More

An electron photomicrograph of two spiral-shaped Treponema pallidum bacteria.
Here we see two Treponema pallidum bacteria scanned by an electron microscope, magnified 36,000X. T. pallidum is the causative agent of syphilis. It contains one of the smallest prokaryotic genomes consisting of abo... Read More
Cultures of a destructive mold called Phomopsis strains that infect both crop and noncrop plants. One of the species of this genus, Phomopsis viticola, cause a plant disease called phomopsis or dead-arm. Usually, infections begin during early growth stages in spring. This affects leaves, fruit, ... Read More
