CROSS NEUTRALIZATION OF SOME KINDS OF SCORPION VENOMS FROM AFRICA AND SOUTH EAST USING VACSERA POLYVALENT SCORPION ANTISERA

Abstract

Preparation of scorpion antivenin includes administration of the venom to a suitable animal - mostly horses- and after an appropriate period collecting the specific antibodies from the se- rum of the inoculated animal. During such procedure the recipient animal may suffer different types of ill-health signs including, generalized asthenia, pallor, skin rashes, muscular pain, hemorrhages, cardiovascular, respiratory problems, nervous signs as paresis and paralysis, break down of tissues, and finally collapse and death, The severity and duration of the ob- served clinical signs depend on the nature, amount and site of the injected venoms Genus scorpion is widespread throughout Western and Central Asia. It is a genus in constant revision and recognizes a number of subspecies. An extensive study was conducted of neutralization of lethality of four species of scorpions from Egypt including Leurus quinquestriatus, An- droctonus crassicauda, Androctonus amorexi, and Androctonus australis and three species of scorpions from Yemen including Leurus quinquestriatus, Bothus spp. and Androctonus aus- tralis by VACSERA equine scorpion antisera.
