  Envenomation by a Razi’s Viper, Macrovipera razii (Serpentes: Viperidae) in Iran: A Neglected Public Health Threat, Report of Two Cases, and Clinical Implications Abstract Snakebite envenomation remains a significant global health concern, with viperid snakes responsible for substantial mortality and disability. In Iran, the genus Macrovipera is of considerable medical importance. Macrovipera razii is an endemic Iranian species distributed across central and southern regions of the country; however, detailed clinical reports of envenomation by this species remain scarce. We report two cases of M. razii envenomation from Iran. The first case involved a 36-year-old male who sustained a bite to the middle finger in Nazmabad, Arak, Markazi Province, Iran, in 2017. He was admitted to hospital approximately 15 min after the bite and received six vials of polyvalent antivenom. Progressive local tissue injury developed, followed by severe necrosis of the affected finger, resulting in ...

Proteomic profile of the venom of three dark-colored Tityus (Scorpiones: Buthidae) from the tropical rainforests of Costa Rica: Proteomics of Tityus spp. from Costa Rica

Abstract

We aimed to elucidate the potential differences in the venom peptide sequences of three Tityus species from Costa Rican rainforests: T. jaimei, T. championi and T. dedoslargos, compared to T. cf. asthenes from Colombia, which could explain the low level of scorpionism in Costa Rica, evidenced by the lack of epidemiological data.
