Reviewed: May 12, 2005 by Biology Editorial Board
Overview: This site contains a collection of short videos of pathogens such as Listeria, Shigella, Yersinia, Salmonella, and Acanthamoeba colonizing or invading and moving within host cells. This website is dedicated to giving the viewer a look into the world of microbial pathogenesis and cell biology through video clips.
Learning Goals: To provide visual display of the interaction between microbial pathogen and
eukaryotic host cell. The movies allow the viewer to visualize complex cellular processes in real time.
Target Student Population: Undergraduate or graduate students in microbiology or cell biology courses.
Prerequisite Knowledge or Skills: Basic knowledge of cellular biology and terminology is needed to fully comprehend the images seen. However, if used in conjunction with teaching a previous understanding of these concepts is not required.
Type of Material: videos
Recommended Uses: These videos are a visual display that will bring the conceptual material relating to actin-based movement to life.
They can be used to challenge student's observation skills by providing little
background on the microbe's role prior to showing the video.
Technical Requirements: browser must be able to read ".mov" files with a quicktime plug-in and use a
java-enabled browser (Netscape or IE 3 or higher)

Evaluation and Observation

Content Quality

Rating: 4.5 stars
Strengths:

  • Well recorded brief views of several pathogens interacting with host cell.
  • Many videos have views with fluorescent tags to enhance images.
  • Brief description of video contents focuses the viewer on the image.
  • Visually the movie clips are quite entertaining and engaging, and will serve to illustrate cellular principles at many educational levels. Should even be of interest to the non-scientist.
Concerns:

  • The events move quickly and in some videos may be difficult to follow.
  • It took quite a long time for my computer to load these movies, even though I do have a high-speed system with all of the required programs.
