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.

Received September 6, 2005. Accepted for publication December 15, 2005.

Acknowledgments: We thank the intensive care staff at Emílio Ribas Institute of Infectology for excellent assistance and patient care. We also thank Jefferson Davis Boyles for correcting the English and style of the manuscript.
