Ratings

Overall Rating:

Content Quality: 5 stars
Effectiveness: 5 stars
Ease of Use: 5 stars
Reviewed: Apr 16, 2001 by Biology Editorial Board
Overview: This virtual textbook provides basic facts regarding the epidemiology, symptoms and treatment of foodborne pathogenic microorganisms and natural toxins. There are 45 links to organisms and toxins and three appendices dealing with concept of infective dose, factors affecting microbial growth in foods, and a summary table of foodborne illnesses. This site brings together in one place information from the Food & Drug Administration, the Centers for Disease Control & Prevention, the USDA Food Safety Inspection Service, and the National Institutes of Health. Links to the National Library of Medicine's Entrez glossary and Morbidity and Mortality Weekly Reports provide information on later outbreaks or incidents of foodborne disease. Links are included to relevant Entrez abstracts and GenBank genetic loci on some pathogenic microorganisms.
Learning Goals: None
Target Student Population: Microbiology students or college students with special assignments related to foodborne diseases
Prerequisite Knowledge or Skills: Basic microbiology
Type of Material: Virtual Textbook
Technical Requirements: HTML

Evaluation and Observation

Content Quality

Rating: 5 stars
Strengths:

Quality of Content: (5.0) (4.0) = (4.5)




  • Site is clearly and concisely laid out and consistent
    presentation for all entries

  • Background material is accurate but last update in March 2000
    and references to outbreaks rarely are post 1997

  • Graphics are limited to a small electron micrograph in the
    heading and an occasional graph of epidemiological data

  • Site does allow for a search through CDC and/or PubMed for
    more recent information

  • Vocabulary is appropriate and linked to a glossary

  • Well designed with complete and accurate material explained
    very concisely.

  • Extremely current and an invaluable reference for information
    on foodborne pathogenic microorganisms and natural toxins.

  • Links to other sites are excellent.
Concerns:

  • May be a bit too much information for some undergraduates.

  • More images and diagrams would be helpful for students.

  • Update some of the direct MMWR links and perhaps include other
    appropriate graphics

Potential Effectiveness as a Teaching Tool

Rating: 5 stars
Strengths:

Potential Effectiveness as a Teaching Tool: (5.00) (4.90) = 5.0




  • Provides basic resource information on diseases.

  • Appendices promote understanding of infective dose and affect
    of temperature, pH, and water activity on microbial growth in
    foods.

  • Search options provide access to current information.

  • Not designed primarily as a comprehensive text, but this is
    clearly stated. A good reference with links to current Morbidity
    and Mortality statistics and genetic information through ENTREZ.

  • Does not necessarily promote conceptual understanding of the
    mechanism of disease action, but rather describes the
    epidemiology, symptoms and treatment of the disease.

  • Well written, but may be a bit technical for many
    undergraduates. More diagrams and images would help.

Ease of Use for Both Students and Faculty

Rating: 5 stars
Strengths:

Usability: (5.0) (5.0) = (5.0)




  • Site is easy to navigate and does not require special
    instructions

  • Each entry is clearly written

  • Limited graphics assures speed in loading

  • All links worked including access to CDC and PubMed

  • Easy to navigate and quick, without any defective links or
    bugs.

  • Contains a searchable index.
Concerns: None
