Recovery of oocysts from adult bovine feces at different initial concentrations when the NaCl flotation method was used

Oocyst concn (oocysts g−1)	% Recovery	No. of oocysts/10 μl	Coefficient of variation (%)	Range (oocysts/ 10 μl)
105	11.1	1,111.6 ± 314.2a	28	649–1,792
104	17.0	169.8 ± 54.1	32	105–298
103	17.7	17.7 ± 6.9	39	9–30
200	12.8	2.5 ± 2.5	100	0–8
50	13.4	0.67 ± 0.84	125	0–2
25	10.8	0.27 ± 0.46	170	0–1

^aMean ± standard deviation (n = 6). The values must be multiplied by 10 to obtain percentages of recovery.
