Background: Seven scorpion species have been reported as human envenoming in Iran. The accurate identification of scorpion sting agents can best help the treatment. This identification also discloses the pathophysiological basis of symptoms and gives the rational for first aids implementation. The study was performed to identify the agents of scorpion sting in Khuzestan.
Materials and Methods: This descriptive research was conducted on 418 scarified scorpions, preserved Ethyl alcohol (70%). The census sampling was performed and the appropriate species were assigned using all morphological criteria by key identification stereo microscopy . The results of scorpion stungs were recorded on a data sheet, classified and compared based on their species and families.
