This Photo Atlas is intended as an aid to students at the Department of Veterinary Disease Biolology, The Faculty of Health and Medical Sciences, University of Copenhagen, Denmark. The atlas supplements the material used in courses in infection microbiology. It contains photographs of bacteria that are included in the courses run at the department. The photographs are accompanied by short descriptions.

The department has chosen to make this Photo Atlas available on the internet for the following reasons: The students have access to the atlas whenever they need it. The department also hopes that others will make use of the atlas.

Use the scrolling menus at the top of the pages to choose a category. Within each category use the dropdown menu at the top right hand or bottom right hand corner of the page to choose bacterium, medium or fungus.

The Photo Atlas contains the following four categories: Bacterial morphology, fungal morphology, phenotyping tests and plating media.

This category contains photographs of bacterial colonies on Blood Agar plates. The plates have been incubated aerobically at 37°C for 24 hours, unless otherwise stated. Photographs of Gram stain, India ink (nigrosin) and phase contrast preparations are shown. Furthermore, photographs of pathological lesions caused by some of the micro-organisms are shown where appropriate.  

This category contains photographs of fungal colonies on Sabouraud Agar plates. The plates have been incubated aerobically at 25°C for several days, unless otherwise stated. Photomicrographs are also included, as are photographs of pathlogical lesions caused by some of the fungi.  

For most of the media, photographs of the following are included: A sterile medium and examples of a bacteria displaying positive and negative reactions.  

The media have been incubated aerobically at 37°C for 24 hours, unless otherwise stated.

For most of the media, photographs of bacteria displaying positive and negative reactions are shown. In some cases a photograph of a sterile medium may also be included.  

The media have been incubated aerobically at 37°C for 24 hours, unless otherwise stated.

This module demonstrates different typing methods often applied in tracing of bacteria and for studies of relatedness between bacterial strains. The main purpose is to illustrate how the typing result will appear when you apply each of the methods.

The section forms a supporting tool for the teaching in molecular epidemiology of infectious diseases and for teaching in veterinary clinical microbiology.
