a
Sebums I to IV are supported by in situ samples of sebaceous secretion and fingerprint residue; sebum V was developed by the author, optimized through prior planktonic culture growth assessments, and based on the median values presented within the literature (data not shown). Quant., quantitative; FM, finger-mark.
