snails are intermediate hosts for schistosome parasites, which cause morbidity and mortality in humans worldwide. We aimed to determine the mating system of , a hermaphroditic vector of schistosomiasis in the African Great Lakes, with the goal of informing the design of genetic studies such as linkage mapping to improve genome assembly and genetic association studies to identify snail resistance genes. To determine the relative rates of outcrossing selfing, we assayed the progeny of experimental crosses of snails in the laboratory using a PCR and restriction enzyme digest to determine snail genotype and parentage.

Spinal schistosomiasis, a rare manifestation of schistosomal infection, can closely mimic the presentation of spinal cord tumors and pose significant diagnostic challenges. We present the case of a 12-year-old boy from northern Ethiopia who experienced progressive back pain, tingling sensations in his lower extremities, and intermittent fever. Initially referred with a presumptive diagnosis of myxopapillary ependymoma for pediatric hematology-oncology evaluation, his marked eosinophilia and history of swimming in local rivers raised suspicion for spinal schistosomiasis.

Human schistosomiasis is a chronic neglected tropical disease caused by blood flukes of the genus Schistosoma, infecting 250 million people worldwide, mostly in sub-Saharan Africa. Recently, thousands of cases have been reported in immigrants to non-endemic countries, including Italy. Serological screening is recommended but so far, no accurate point-of-care (POC) and lab-free test is available.

Praziquantel is currently the only effective treatment for schistosomiasis, but several limitations underscore the need for new therapeutic agents. Recent promising in vitro results with Artemisia species and the success of A. annua and its active compound artemisinin in treating parasitic infections warrant the need for further studies.

In the present study, the hexane extract from branches of (Winteraceae) displayed potent activity against parasites (100% mortality of the worms at 200 μg/mL). Bioactivity-guided fractionation afforded, in addition to the previously reported bioactive sesquiterpene 3,6-epidioxy-bisabola-1,10-diene, two chemically related drimane sesquiterpenes-polygodial () and 9-deoxymuzigadial (). The anti- effects for compounds and were determined in vitro, with compound demonstrating significant potency (EC value of 10 μM for both male and female worms), while was inactive.
