Determination is done using intelligent rules and the complete taxonomic kingdoms Bacteria, Chromista, Protozoa, Archaea and most microbial species from the kingdom Fungi (see Source). The input can be almost anything: a full name (like &quot;Staphylococcus aureus&quot;), an abbreviated name (like &quot;S. aureus&quot;), an abbreviation known in the field (like &quot;MRSA&quot;), or just a genus.

<p>Group 2 consists of all microorganisms where the taxonomic phylum is Proteobacteria, Firmicutes, Actinobacteria or Sarcomastigophora, or where the taxonomic genus is <em>Aspergillus</em>, <em>Bacteroides</em>, <em>Candida</em>, <em>Capnocytophaga</em>, <em>Chryseobacterium</em>, <em>Cryptococcus</em>, <em>Elisabethkingia</em>, <em>Flavobacterium</em>, <em>Fusobacterium</em>, <em>Giardia</em>, <em>Leptotrichia</em>, <em>Mycoplasma</em>, <em>Prevotella</em>, <em>Rhodotorula</em>, <em>Treponema</em>, <em>Trichophyton</em> or <em>Ureaplasma</em>. This group consequently contains all less common and rare human pathogens.</p>
<p>Group 3 (least prevalent microorganisms) consists of all other microorganisms. This group contains microorganisms most probably not found in humans.</p>
<h3>Background on matching scores</h3>
<p>With ambiguous user input, the returned results are chosen based on their matching score using <code><a href='mo_matching_score.html'>mo_matching_score()</a></code>. This matching score is based on four parameters:</p><ol>
<li><p>The prevalence \(P\) is categorised into group 1, 2 and 3 as stated above;</p></li>
<li><p>A kingdom index \(K\) is set as follows: Bacteria = 1, Fungi = 2, Protozoa = 3, Archaea = 4, and all others = 5;</p></li>
<li><p>The level of uncertainty \(U\) needed to get to the result, as stated above (1 to 3);</p></li>
<li><p>The <a href='https://en.wikipedia.org/wiki/Levenshtein_distance'>Levenshtein distance</a> \(L\) is the distance between the user input and all taxonomic full names, with the text length of the user input being the maximum distance. A modified version of the Levenshtein distance \(L'\) based on the text length of the full name \(F\) is calculated as:</p></li>
</ol>
<p>$$L' = F - \frac{0.5 \times L}{F}$$</p>
<p>The final matching score \(M\) is calculated as:
$$M = L' \times \frac{1}{P \times K} * \frac{1}{U}$$</p>
<p>All matches are sorted descending on their matching score and for all user input values, the top match will be returned.</p>
