&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;== Principles ==&lt;br /&gt;
&lt;br /&gt;
* Analyze and present data at least annually&lt;br /&gt;
* Include only species with at least 30 isolates tested&lt;br /&gt;
* Include diagnostic, not surveillance, isolates&lt;br /&gt;
* Include results only for drugs that are routinely tested&lt;br /&gt;
* Include the first isolate per patient in the period analyzed, irrespective of the body site from which the specimen was obtained or the antimicrobial susceptibility pattern&lt;br /&gt;
* Calculate the percentage susceptible; do not include the percentage of isolates with intermediate susceptibility&lt;br /&gt;
* For [[Streptococcus pneumoniae]]:&lt;br /&gt;
** Calculate and list both the percentage susceptible and the percentage of isolates with intermediate susceptibility for [[penicillin]]&lt;br /&gt;
** Calculate and list the percentage susceptible for [[cefotaxime]] or [[ceftriaxone]] using both the meningitis and nonmeningitis breakpoints&lt;br /&gt;
* For [[viridans group streptococci]], calculate and list both the percentage susceptible and the percentage of isolates with intermediate susceptibility for [[penicillin]]&lt;br /&gt;
* For [[Staphylococcus aureus]], calculate and list the percentage susceptible for all isolates, as well as for the subset of methicillin-resistance [[Staphylococcus aureus]]&lt;br /&gt;
