TABLE 5.

Percentages of recovery of purified oocysts from sandy loam soil as a function of the dispersing solution

Dispersing solution	% Recoverya	No. of oocysts/10 ml	Coefficient of variation (%)
Distilled H2O	0.06	2.5 ± 2.6b	104
PBS	0.02	0.7 ± 0.3b	43
Tween 80	3.2	172 ± 12.3c	7.2
Triton X-100	5.9	236 ± 52.9d	22
Tris-Tween 80	14.7	588 ± 121c	21

^aThe initial concentration was 4 × 10⁴ oocysts per 25 g of soil. The least significant difference (P < 0.05) was 2.2%. 

^bMean ± standard deviation (n = 4). The value must be multiplied by 10 to obtain the percentage of recovery. 

^cMean ± standard deviation (n = 6). The value must be multiplied by 10 to obtain the percentage of recovery. 

^dMean ± standard deviation (n = 12). The value must be multiplied by 10 to obtain the percentage of recovery.
