Hymenolepiasis is an infection caused by Hymenolepis nana (H. nana) and H. diminuta (H. diminuta). Hymenolepiasis is prevalent throughout the world with human infections with H. nana being frequently reported in the literature as compared to H. diminuta. Hymenolepiasis is more frequent among children, and most human infections remain asymptomatic and selflimited. Symptoms including abdominal pain, diarrhea, and vomiting are frequently noted in the cases of heavy infections. We report a case of hymenolepiasis caused by H. nana in a pregnant woman.

“…Humans become infected by the accidental ingestion of intermediate host such as fleas, flour beetles and other insects commonly found in grain and cereal containing the cysticercoid larvae. Infection resulting from incidental ingestion of the infective stage are often asymptomatic but heavy infection can result in persistent abdominal pain, diarrhea and anorexia (Ahmad et al., 2017; Alvarez-Fernandez et al., 2012).…”

This study identified the endoparasites in Brown rat ( Rattus norvegicus) during May to July 2017 in Grenada, West Indies. A total of 162 rats, 76 females and 86 males were trapped from St. George and St. David parishes in Grenada. The collected fecal samples were examined for parasitic eggs and/or oocysts using simple fecal flotation technique. Adult parasites found in the intestinal tract were examined for identification. The overall prevalence of intestinal parasites among rats was 79 %. Ten helminth species were recovered, several of which were reported for the first time in rodents in Grenada. The internal parasites consist of seven nematodes ( Angiostrongylus spp., Nippostrongylus braziliensis , Heterakis spumosa , Strongyloides ratti , Aspiculuris tetraptera , Syphacia spp. and Protospirura spp.), one cestode ( Hymenolepsis diminuta ), one acanthocephalan ( Moniliformis moniliformis ) and one protozoa species ( Eimeria spp.). The most prevalent zoonotic species were Angiostrongylus spp. (35.2%), Hymenolepsis diminuta (7.4%) and Moniliformis moniliformis (3.1%). Several nonzoonotic endoparasites; which included Nippostrongylus braziliensis (50.6%), Heterakis spumosa (15.4%), Strongyloides ratti (43.2%), Aspiculuris tetraptera (2.5%), Syphacia spp . (1.9%), Protospirura spp. (1.2%) and Eimeria spp. (4.7%) were also identified. The most prevalent parasites were Nippostrongylus brasiliensis (50.6%), Strongyloides ratti (43.2%) and Angiostrongylus spp. (35.2%). Co-infections occurred with up to six species per rat showing different combinations of parasitic infections.

“…Hymenolepis diminuta is a common rat and mice tapeworm with a worldwide distribution throughout the world; however, it is rarely found in man. 1,2 The tapeworm has an indirect life cycle in which it requires the obligatory intermediate host (arthropods as) in addition to the definitive host (rodents). Beetles (Tenebrio and Tribolium), fleas (Ctenocephalides, Xenopsylla, and Pulex), cockroaches, or caterpillars may serve as the intermediate hosts after ingestion of H. diminuta eggs excreted in the rodent's feces.…”

He was initially diagnosed with food allergy before receiving the correct diagnosis for his illness.…”

“…The common detection method for H. diminuta infection is by examination of concentrated stool samples for the presence of eggs or proglottids. 2,15 However, since many infected persons were mostly asymptomatic and some were detected during field surveys, it was not able to give prompt treatment to them. 8 In addition, there has been a report of an untreated H. diminuta case due to incorrect diagnosis by laboratory personnel.…”
