Table 2.
Vertebrate (species) | No. detected (% of total with detectable vertebrate DNA) |
---|---|
Human (Homo sapiens) | 70* (47%) |
Goat (Capra hircus) | 63 (43%) |
Chicken (Gallus gallus) | 9 (6%) |
Sheep (Ovis aries) | 4 (3%) |
Guinea Pig (Cavia porcellus) | 1 (< 1%) |
Pig (Sus scrofa) | 1 (< 1%) |
Our assay has a 6% false positive rate for human DNA.39 Using Equation 4 and the values listed in Table 3, we estimated that ∼35 of the samples with detectable human DNA represent human blood-fed fleas.
