- aGiardia duodenalis detection rates were based on PCR analysis of the triosephosphate isomerase (tpi), glutamate dehydrogenase (gdh) and β-giardin (bg) genes
- bDetection rates of G. duodenalis (χ2 = 17.25, P < 0.0001) and E. bieneusi (χ2 = 20.83, P < 0.0001) are significantly higher in animals with loose stools than in those with normal stools
- cThe detection rate of E. bieneusi is significant higher in males than in females (χ2 = 14.391, P = 0.0001)
- dThe detection rate of G. duodenalis is significantly higher in 1–3 year-old animals than in older animals (χ2 = 38.11, P < 0.0001). In contrast, the detection rate of E. bieneusi is significantly lower in 1–3 year-old animals than > 3 years (χ2 = 9.90, P = 0.0016)
