  First record of Megaselia abdita (Schmitz, 1959) (Diptera: Phoridae) infestation in captive tarantulas (Araneae: Theraphosidae Abstract Flies of the genus Megaselia Rondani, 1856 exhibit exceptional ecological flexibility, with certain species acting as facultative parasites. This study presents the first documented cases of Megaselia abdita (Schmitz, 1959) infesting captive tarantulas (Araneae: Theraphosidae, Ceratogyrus darlingi Pocock, 1897 and Psalmopoeus irminia Saager, 1994) in terrarium settings. Our observations demonstrate that M . abdita colonise artificial habitats and exploit spider hosts similarly to Megaselia scalaris . Citation: Szymański, D.M., Szymański, D., Kłonowski, P. (2026).

Large animal models for the assessment of snakebite envenoming therapies


Abstract

Snakebite envenoming causes over 100,000 deaths annually, creating a need for more effective therapies. Traditionally, most preclinical testing relies on murine models with limited translational value. This review highlights the value of large animal models, particularly sheep and pigs, for studying venom toxicokinetics and antibody and small-molecule pharmacokinetics. Implementing clear guidelines and standardized endpoints in large-animal studies could help advance the clinical translation of new snakebite treatments.
