Acceptable use information

What's OK:

If you have permission to use this library, you may use the images 

   1) in presentations (computer-generated or slides) or 

   2) on posters (one print only, of any one image).  Please credit the CBE and the source noted.

 

What's not OK:

To submit any of these images for print reproduction (the quality is not adequate anyway!) or to make multiple copies for distribution without express written permission from the source and CBE.

 

How to acquire images

1. Click on the image you want to use – you will be linked to a full-sized (11" x 7.33") version of the image.

 

2. Right-click on the image and select "Copy" from the dialogue box that appears.

 

3. Open a presentation in PowerPoint. Make sure that page set-up is for 35mm slides.  Select page you want the image on.  From the edit menu, select "Paste."  Voila!

 

If you have questions, contact Peg Dirckx.

Description

In addition to oxygen/carbon dioxide exchange, the human lungs are effective “scrubbers”— eliminating inhaled microbes. In the tiny alveoli sacs of the lung, single microbes are quickly ingested by activated neutrophils.

Description

When the immune response is compromised, bacteria are able to colonize the alveoli, and to form biofilms. Biofilms do not trigger the neutrophils to become activated, even in the presence of antibodies (yellow symbols). When biofilm cells are released from the community singly, they are readily “recognized” and ingested by neutrophils.

Description

Studies of neutrophil / biofilm interactions in Pseudomonas aeruginosa biofilms have shown that neutrophils retain their basic un-activated round shape—becoming only minimally active—and settle into the biofilms, releasing a “cloud” of single cells. A well-established biofilm will grow thicker over time, and may calcify (white areas), rendering the alveolus inactive.

Description Hundreds of microbial species colonize the human mouth. Some species are pathogenic, and can cause infection, tooth decay and gum disease.

Description Three examples of the many possible points of entry for bacteria are shown here, along with common areas of secondary infection (highlighted in green). Once bacteria enter the circulatory system, they can reach all parts of the body.
