Microbiology

Identify a taxon based on its phenotypic characteristics. View a list of the typical positive and negative reactions for a specified organism and compare the reactions of two or more species.

General

Background information regarding GIDEON and some features that work across all modules.

  • Resources and References +

    Access references in GIDEON to the resources used to keep information up to date.

  • Personal Notes Only available for individual subscribers +

    Personal Notes are available in each of the modules:

    • Infectious Diseases: contains two personal note options
      • In the first option (in the main window), you can add information regarding a specific patient whose signs and symptoms you have already entered.
      • In the second option (in the Diagnosis information window), you can include information on a disease, local or hospital experience with a specific disease, incidence, important telephone numbers, and details regarding prior cases of the disease.
    • Microbiology: contains two personal note options:
      • The first (in the main window) allows for recording of additional information regarding an isolate that you wish to save in the module.
      • The second (in the Microbiology information window) is for insertion of additional information, for example a specific taxon (Bacteria, Yeast, Mycobacteria), local experience, details regarding submission of specimens, and important contact personnel.

    Notes

    • Save notes using the button next to the Notes box.
    • In the Institutional version, this option is editable only by the administrator.
  • Cases Only available for individual subscribers. +

    Save and Open cases

    A case study is a file that the user creates in the Infectious Diseases or Microbiology modules to store only the data the user has entered. These data take the form of:

    • Selected signs and symptoms (Infectious Diseases)
    • Selected tests (Microbiology)
    • Personal Notes (Infectious Diseases and Microbiology)

    The case file does not store any diagnostic results or microbiological identification or characterization results.

  • Bayesian Analysis +

    Thomas Bayes, an English Clergyman (1702-1761) authored a method of predicting events based on known probability of occurrence. The method, Essay Toward Solving a Problem in the Doctrine of Chance (PDF), was published posthumously in 1763, and may be illustrated as follows.

    Suppose that, on a certain island,

    • Q fever (Q), and
    • ornithosis (O)

    are the only diseases known to cause

    • cough (C)
    • hepatomegaly (H), and
    • rash (R)

    Let us define:

    PCQ, PHQ and PRQ The respective incidences of these symptoms in Q fever.

    PCO, PHO and PRO The corresponding figures for ornithosis.

    The respective annual incidences of the two diseases are IQ and IO.

    Bayesian analysis tells us that the probability of a patient having Q fever – given cough, fever, and hepatomegaly is:

    PCQ * PHQ * PRQ * IQ

    (PCQ * PHQ * PRQ * IQ) + (PCO * PHO * PRO * IO) + etc

    The “etc” in our denominator indicates that data for each additional endemic disease (d) having these symptoms would be added on to this string [e.g., (PCd * PHd * PRd * Id)].

    The above example consists of two diseases and three symptoms. GIDEON can access disease rates for over 200 countries, and compute the individual likelihood of over 300 diseases given hundreds of clinical findings !

    In addition to statistical data for disease and symptom occurrence, GIDEON incorporates the absence of symptoms into its formulae. Thus, if a rash is expected in 95% of patients with measles, and the user indicates that rash is not present, the resulting Bayesian formulae will incorporate “1 – .95” or 5% for the percentage of measles patients presenting with “non-rash.” Since this feature virtually doubles the discriminative capacity of the program, the user is encouraged to indicate all firm negative findings when entering symptoms and signs. Similar analysis is applied to the identification of bacteria in the Microbiology module.
