“…Diagnosis of H. nana and H. diminuta relies on the microscopic detection of eggs in fecal samples [19]. Ethyl acetate or ether-based concentration techniques [8] are recommended to increase sensitivity, as egg numbers can be very low.…”

Introduction: Parasites are a major public health problem in developing countries. A coproparasitological and immunoparasitological study was conducted in Burkina Faso, in the rural village of Touguri, in November and December 2011. The coproparasitologic analysis was conducted in the pediatric population and seroprevalence surveys were conducted in the adult population to research intestinal, blood, and helminth parasites. Methodology: The coproparasitologic study was performed on stool samples using two diagnostic methods -standard microscopy and the FLOTAC technique. The total of 49 stool samples analyzed were obtained from children between two months and eleven years of age. The serology study was carried out to evaluate the prevalence of P. falciparum, Echinococcus spp., Tenia solium, and A. lumbricoides using different immunological techniques such as ELISA and Western Blot techniques. The study population included 85 adult patients between 15 and 70 years of age. Results: Results of coproparasitological analyses showed Hymenolepis nana as the only helminth found, in 28.6% of the total number of patients. Results of serological evaluation revealed a practically null prevalence of Echinococcus, Taenia solium, and Ascaris lumbricoides, and a 77.64% prevalence of Plasmodium falciparum. Conclusions: Despite the small number (especially in terms of coprological samples) of individuals examined, this study showed that the parasite prevalence in a rural area of Burkina Faso has a significant impact in the general population, particularly in children. Another finding was that FLOTAC had a higher sensitivity than the widely used ethyl ether-based concentration technique for coprological sample analysis.

“…The red flour beetle, Tribolium castaneum Herbst (Coleoptera: Tenebrionidae), is an important stored-grain pest worldwide (Granousky, 1997;Sinha and Watters, 1985;Small, 2007), and is also an intermediate host to Hymenolepis diminuta (Cestoda: Cyclophyllidea) known as rat tapeworm, commonly found in rat feces. Eggs of H. diminuta are passed in the feces of the infected definitive hosts, and the mature eggs can be ingested by Tribolium beetles; when oncospheres are released from the eggs, they penetrate the intestinal wall of the host and subsequently develop into cysticercoid larvae (Schantz, 1996).…”

“…Alternatively, the embryonated H. nana eggs shed in feces can directly infect humans upon ingestion. Auto-infection with eggs remaining in the intestine and hatching in situ is also possible, allowing infections to become perpetuated despite the short life span of the adult worm of 4-6 weeks (Schantz 1996). Adults of the related species Hymenolepis diminuta, the rat tapeworm, are much longer (20-60 cm), and their eggs have a round shape of approximately 60-80×70-85 μm.…”

FLOTAC for the diagnosis of Hymenolepis spp. infection: proof-of-concept and comparing diagnostic accuracy with other methods

Hymenolepis nana is the most common cestode parasitizing humans, yet it is under-diagnosed. We determined the optimal flotation solution (FS) for the diagnosis of this intestinal parasite with the FLOTAC method, and compared its diagnostic accuracy with an ether-concentration technique and the Kato-Katz method. Zinc sulphate (specific gravity 1.20) proved to be the best-performing FS. Using this FS, we detected 65 H. nana infections among 234 fixed fecal samples from Tajik and Sahrawi children (prevalence 27.8 %). The ether-concentration technique detected 40 infections (prevalence 17.1 %) in the same samples. Considering the combined results as a reference, the sensitivities of FLOTAC and ether-concentration were 95.6 % and 58.8 %, respectively. The Kato-Katz method resulted in a prevalence of only 8.7 %. In terms of eggs per gram of stool, a significantly (P <0.05) higher value was obtained with the FLOTAC and Kato-Katz techniques compared to ether-concentration. In another study carried out in China, the FLOTAC method detected six Hymenolepis diminuta infections in 302 fecal samples, whereas five samples were found positive with the Kato-Katz technique. We conclude that FLOTAC is an accurate coprodiagnostic technique for H. nana and H. diminuta, two species which join a growing list of intestinal parasites that can be reliably diagnosed by this technique.
