ONLINE ATLAS OF MICROBIOLOGY

Microbiology is a broad term which includes bacteriology, virology, mycology, parasitology and imunology. On this website you will find images of bacteria. Most of them are medically important, cultivable bacterial species. So it would be better to use the term

ATLAS OF BACTERIOLOGY

WHY DID WE CREATE THIS PAGE?

Nearly everybody has had a sore throat and maybe even been to see the doctor. He looked in your mouth told you something about tonsillitis and gave you some antibiotics, maybe even took a throat swab. After a week you were informed that the cause of your troubles was e.g. Streptococcus pyogenes or a beta-hemolytical streptococcus group C, identified in a laboratory of clinical microbiology. And maybe you wanted to know more. What does your "enemy" look like? So you went to the library, went through the web...and you probably found a lot of information on the topic. Perhaps you even found some pictures - mostly from the electron microscope.

But many pathogenic bacteria are able to grow quite well on the surface of solid cultivation media and form colonies consisting of millions of bacterial cells. Bacterial colonies have generally 1 to 10 mm in diameter so you can quite literally touch them. Although the appearance of colonies is strongly influenced by the composition of cultivation medium and cultivation conditions the ability to correctly distinguish between pathogenic bacteria from the rest of bacterial flora often plays a crucial role in the diagnosis process.

In the pictures on this website we'd like to show you some bacteria - those that grow well on cultivation media and can be pathogenic (under certain circumstances) as well as their opposites - bacteria producing antibiotics used in the treatment of the pathogenic ones. The pictures on the main page are each devoted to a bacterium accompanied by an abbreviated text, usually from Wikipedia (http://en.wikipedia.org) and some basic information about the tests that may be used to confirm their identity. We put some general information about possible treatments for each bacterium but as resistance of bacteria is increasing it is necessary to test for antibiotic susceptibility in practically every bacterial strain.

The information you will find here and the pictures of bacteria can not be considered complete. There are hundreds of cultivation media used in clinical laboratories around the world for isolation and identification of various bacteria. This is why we‘ve struggled to use general purpose cultivation media which are used in laboratories all around the world.

In the future we'd like to improve and add links to other external web pages you might be interested in and of course to complete the gallery on this website. We hope this page will be useful for you and you will find here what you have been looking for.....
