The number of large Trichuris spp. eggs observed in individ-
ual samples was very low,usually1–3 eggs were found by the
FLOTAC and ether-concentration techniques, whereas consider-
ably higher counts of standard T. trichiura eggs were common
(Steinmann et al.,2008b). Without exception, large Trichuris spp.
eggs were found in individuals also excretings tandard-sized eggs
in their stools (Fig. 1C). The size of the observed Trichuris spp. eggs
was not routinely determined but did not appear to vary consid-
erably; the size of the large Trichuris spp. egg depicted in Fig. 1B is
76×34m.
