Streptomyces spp. on various cultivation media. Production of different pigments and formation of aerial mycelia. Colonies after approximately 15 days of cultivation in aerobic atmosphere, 28°C. Environmental isolates.

Streptomyces is the largest genus of Actinobacteria and the type genus of ... Read More

Virus causes animal die-off along the coast of Peru

A dying pelican crawls away from the surf to die on the beach of Paita, Peru on May 2, 2012. According to Peruvian vice minister of Environment, Gabriel Quijandria, the cause of death of thousands of fish, sea birds and diverse animal wildlife that has been washing ashore in the northern coasts ...

Mycoplasma - adhesion of symbiont infection structure to host

This scanning electron micrograph shows mycoplasma (colorized pink), a genus of bacteria that lack a cell wall. Without a cell wall they are unaffected by many common antibiotics, such as penicillin, or other beta-lactam antibiotics that work by targeting cell wall synthesis. These mycoplasma ar... Read More

Examining Virus Bacterium Associations




Virus-bacterium associations were examined in the natural environment of a termite's hindgut. Three general scenarios were seen. In the first (1) there was a one-to-one association: one type of virus matched one type of bacterium host. In the second (2) the host bacterium was associated wi... Read More

Caulobacter crescentus

The tiny water bacterium Caulobacter crescentus secretes a sugary substance so sticky that just a tiny bit could hold several cars together. First, it attaches to a surface at the end of its cell body, which has a propeller-like flagellum. On contact, the flagellum stops moving with help from ne... Read More

Slime mold Arcyria denudata

Arcyria called Cotton Candy Slime. A Myxomycetes 1 mm tall. Read More

Neisseria gonorrhoeae

This photomicrograph is showing Neisseria gonorrhoeae in a cervical smear using the Gram-stain technique. Thanks to the CDC's PHIL for the image. Read More

Micrasterias denticulata

Micrasterias is a Desmid - a group of green algae mostly found in neutral to acidic fresh waters and sphagnum bogs. Most are unicellular, though a few form chain-like colonies. Each cell is constructed of 2 semicells which are mirror images of each other. In Micrasterias the cells are flattened ... Read More

Predictably beautiful

As the bacteria grow within a biofilm, they organize themselves into reproducible patterns and shapes that can be predicted with mathematical models.
Image: Confocal microscopy of a bacterial biofilm composed of Escherichia coli expressing the fluorescent proteins mCherry and sfGFP. The image w... Read More

Yersinia pestis

As a closer view of PHIL 12265, this photograph depicts the colonial morphology displayed by Gram-negative Yersinia pestis bacteria, which was grown on a medium of sheep's blood agar (SBA), for a 72 hour time period, at room temperature. Y. pestis is the bacterium responsible for causing the inf... Read More

Mucor sp. fungal organism

Under a magnification of 200x, and using a lactophenol cotton blue mount fixation technique, this photomicrograph reveals some of the ultrastructural morphology exhibited by a Mucor sp. fungal organism. This image depicts two sporangia, a mature structure, which had ruptured, releasing its conte... Read More

Burkholderia cepacia

Scanning Electron Micrograph of Burkholderia cepacia.

Burkholderia cepacia is the name for a group or “complex” of bacteria that can be found in soil and water. B. cepacia bacteria are often resistant to common antibiotics.

B. cepacia poses little medical risk to healthy people. However,... Read More

Oral bacterial colonies, including Capnocytophaga and Aggregatibacter

This color-enhanced photomicrograph shows different species of bacteria that cause dental plaque - a colorless film that forms on teeth caused by the growth of bacterial colonies. Plaque develops naturally, and in most cases can be easily removed with regular brushing. However, if left it can ha... Read More

Enterococcus faecalis

The bacterium, Enterococcus faecalis, which lives in the human gut, is just one type of microbe that will be studied as part of NIH's Human Microbiome Project. Read More

Wheat infected with ergot fungus

Confocal micrograph of wheat stigma hairs (blue) infected with ergot fungus (light pink). The stigma is the female part of the plant. The plant is fertilised by the (male) pollen grain, which sticks to a stigma hair causing growth of a pollen tube into the plant's ovary, causing an embryonic whe... Read More
