Table 2 Comparison of the number of canine and feline fecal samples with at least one of the seven evaluated parasite species/genus detected and those with co-infection(s) for zinc sulfate centrifugal flotation (ZCF) and the qPCR panel
|  | ZCF | qPCR | Pearson’s chi-square | Degrees of freedom | P-value |
|---|---|---|---|---|---|
Samples with at least 1 parasite species/genus detected | 354 | 457 | 528.52 | 1 |  < 0.0001 |
Co-infection, samples with 2 or more detected | 66 | 172 | 279.49 | 1 |  < 0.0001 |
Co-infection, 2 parasites | 51 | 131 | 152.60 | 1 |  < 0.0001 |
Co-infection, 3 parasites | 13 | 33 | 207.63 | 1 |  < 0.0001 |
Co-infection, 4 parasites | 2 | 7 | 264.57 | 1 |  < 0.0001 |
