Figure 1. PCR based screen for presence of Demodex 16S rDNA in samples with no visually identifiable mites.

Figure 1

Lanes labeled 1–29 represent samples from single individual participants. Lanes labeled M represent 100 bp molecular weight size markers. (a) PCR products indicate the presence of Demodex DNA in 100% of the screened samples from individuals over the age of 18. (b) PCR products indicate the presence of Demodex DNA in 70% of the screened samples from individuals 18 years of age.
