A. Clavel et al., COMPARISON OF 2 CENTRIFUGATION PROCEDURES IN THE FORMALIN-ETHYL ACETATE STOOL CONCENTRATION TECHNIQUE FOR THE DETECTION OF CRYPTOSPORIDIUM OOCYSTS, International journal for parasitology, 26(6), 1996, pp. 671-672
A comparison between the standard formalin-ethyl acetate (FEA) stool c
oncentration procedure (centrifugation at 400 g for 2 min) and a modif
ication proposed to increase the recovery of Cryptosporidium oocysts (
500 g for 10 min) was performed on 73 formalin-preserved stool specime
ns known to be positive for Cryptosporidium. False-negative results we
re obtained with both methods, but the increase in centrifugation time
and force resulted in the detection of a higher number of oocysts and
positive samples. The modified procedure had a sensitivity significan
tly higher than the standard method (99% compared to 86%, P = 0.0045).
