AI Article Synopsis

  • - Contact with the Lonomia obliqua caterpillar can lead to a dangerous condition called hemorrhagic syndrome due to its venom activating certain blood factors.
  • - The venom affects prothrombin and factor X and causes the breakdown of fibrinogen, potentially leading to severe bleeding issues.
  • - Despite previous reports not indicating hemolysis in humans, this text presents a confirmed case where Lonomia venom indeed caused hemolysis in a human subject.

Article Abstract

Contact with a caterpillar of the genus Lonomia can result in a hemorrhagic syndrome. Lonomia obliqua venom activates prothrombin and factor X and promotes fibrinogenolytic activity. Although crude L. obliqua bristle extract can induce hemolytic activity in human and rat erythrocytes, there have been no reports of hemolysis in the cases of human contact. We report a confirmed human case of Lonomia venom-induced hemolysis.
