Salmonella is a gram-negative, rod-shaped bacilli that can cause diarrheal illness in humans. They are microscopic living creatures that pass from the feces of people or animals to other people or other animals.
The Salmonella family includes over 2,300 serotypes of bacteria which are one-cel... Read More

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
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
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

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

Its simply beautiful, one of the first isolations I made. Read More
Dark-field preparation of Treponema pallidum. (approx X1000). Taken from the Wistreich Collection, appearing exclusively on MicrobeWorld. Read More
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
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
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
Pseudomonas aeruginosa. Imepinem did that wird zone next to ampicilin sulbactam. Wat phenomen are that? Its that synergism? And it wil have activity in vivo? Thnx
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
bc5 - A close-up view of a pour plate using Serratia marcescens as the inoculum. A variety of colonial shapes can be seen. Taken from the Wistreich Collection, appearing exclusively on MicrobeWorld. Read More
To help scientists understand how the Penicillium stoloniferum virus interacts with its hosts, and how it replicates and matures over its lifecycle, the virus structure was solved at the very high-resolution of 7.3 angstroms. Running the automated AUTO3DEM software on a San Diego Supercomputer C... Read More
