A high prevalence of Taenia solium infections, including cysticercosis with viable cysts, was identified in twelve remote villages surrounding Ranomafana National Park, Madagascar. The study revealed that nearly 28% of participants tested positive for anti-cysticercal antibodies, with a 12.4% prevalence of circulating cysticercal antigens indicating active infections. Key risk factors included open defecation and living in households with more than four people, while females and those using river water as a source were less likely to have viable cysts. The research employed a community-based cross-sectional survey, combining stool and serum sample analysis with PCR sequencing and ELISA assays to characterize Taenia species and detect cysticercal antibodies or antigens.

Researchers identified a novel species of Eimeria, a coccidian parasite, in wild Yellow-eyed Penguins (Megadyptes antipodes), with significantly higher prevalence and pathogen load than previously reported for this host or other free-living Sphenisciformes. The study compared two populations: one on Enderby Island (sub-Antarctic) with 76.6% prevalence and a mean of 9,723 oocysts per gram of feces, and another on New Zealand's South Island with 58.54% prevalence and 1,050 oocysts per gram. Morphological analysis suggested the presence of a single Eimeria species across both sites, despite measurable differences in oocyst dimensions. The findings highlight a previously understudied host-parasite relationship that may have implications for the endangered penguin's population stability.

A rare and previously unrecognized woodblock print of the Avatamsaka Sutra (Jin edition), Volume 53, has been identified among the collections of Busoam Hermitage in Namhae, South Korea. This discovery provides new evidence that Haeinsa Temple had the resources and expertise to produce Tripitaka Koreana woodblocks as early as 1098, predating the official 1236 national project. The study employed codicological analysis—comparing script styles (書體), sequence (函次), and carver names (刻手名)—to establish that this volume shares identical characteristics with one of Haeinsa's four extant Tripitaka Koreana woodblocks, confirming its authenticity and rarity. This finding underscores the need to re-evaluate Haeinsa's classification system for these texts and highlights the print's potential as a source text for future restoration efforts.
