<p>Two categories were used for cross-validation of the model, either type 1 or type 2. Clinical isolates were treated as an unknown class and cross-validated sensitivity, specificity, and class error were based on their classification prediction score with their respective reference strain control class.

NA-SERS specificity spectra

Wavenumber and intensity values for 521 spectra of Mycoplasma pneumoniae, other mycoplasmas, and background controls

Comparison of averaged, baseline-corrected, and normalized SERS spectra for type 1, type 2, and type 2V genotypes.

<p>Raw spectra of all type 1 (n = 155), type 2 (n = 135), and type 2V (n = 60) clinical isolates and controls were averaged, baseline-corrected, and normalized using GRAMS32/A1 spectral software package (Galactic Industries, Nashua, NH). Red, average spectrum of all type 1 <i>M</i>. <i>pneumoniae</i> strains; green, average spectrum of all type 2 <i>M</i>. <i>pneumoniae</i> strains; blue, average spectrum of all type 2V <i>M</i>. <i>pneumoniae</i> strains. Peaks unique to a specific genotype of <i>M</i>. <i>pneumoniae</i> are indicated by arrows and identified above the spectral fingerprint. Type 1 peaks, red arrows; type 2 peaks, green arrows; and type 2V peaks, blue arrows. Inset at top right of image depicts zoomed-in view of the type 2 doublet at 767 and 778 cm^-1.</p

Cross-validated PLS-DA modeling statistics for the prediction performance for species discrimination between <i>M</i>. <i>pneumoniae</i> and nine other human commensal and pathogenic mycoplasma species individually.

<p>For species discrimination, three categories were incorporated to cross-validate the model: either category 1: growth medium control (GMC); category 2: <i>M</i>. <i>pneumoniae</i> (M129); or category 3: other mycoplasma species in question. Eight spectra from each category were of known class and two spectra from each category were treated as unknowns to generate a cross-validated prediction model. Cross-validated sensitivity, specificity, and class error were based on the classification prediction score for each category.</p><p>Cross-validated PLS-DA modeling statistics for the prediction performance for species discrimination between <i>M</i>. <i>pneumoniae</i> and nine other human commensal and pathogenic mycoplasma species individually.</p
