Diagnosis of gastrointestinal parasites in reptiles: comparison of two coprological methods

Table 4 Differences between CNF and SAF for individual parasitic stages

Parasite stages	Number of samples				Statistical results
	Negative in both tests	Only positive in CNF	Only positive in SAF	Pos in CNF and SAF	Fisher's exact test	McNemar test for marginal homogeneity	Differences of the probabilities of detection between CNF and SAF (%)
Oocysts	42	10	2	5	0.009	0.04	13,6
Flagellates	44	15	0	0	Ø³	< 0.0001	25,4
Oxyurids	35	12	0	12	< 0.0001	0.0005	20,3
Ascarids	46	5	1	7	< 0.0001	0.22	6,8
Strongylids (eggs + larvae)	41	1	5	12	< 0.0001	0.22	6,8
Nematodes¹	32	9	1	17	< 0.0001	0.02	13,6
Trematodes	50	0	4	5	< 0.0001	0.13	6,8
‘Heavy’ parasitic stages²	24	6	17	12	0.09	0.03	18,6

The association between the number of parasites found in each method was tested using Fisher's exact test and the marginal homogeneity was checked with the McNemar test.
¹Strongylid-, ascarid-, spirurid-, strongyloid- and Capillaria -type eggs.
²Larvae, trematode eggs, amoebae, ciliates.
³Fischer exact test no applicable.
