Improvement of purification methods for F(ab')2 fraction of equine hyperimmune plasma against scorpion venom

Reduction of Purification Time of Polyspecific Equine F(ab´)2 Antivenom against Scorpion Envenomation

Background and Aims: In this study we improved the purification of immunoglobulins from equine antiserum raised against the venom of 6 types of scorption species. Caprylic acid (octanoic acid), a fatty acid, was found to have no effect on the activity of the enzymes pepsin, which is used in antivenom purification to digest Fc fragment of immunoglobulins to obtain F(ab´)2. Materials and Methods...

Preparation and biodistribution study of a 99mTc-labeled toxic fraction of Iranian mesobuthus eupeus scorpion venom

  Introduction: Iranian scorpion species are classified in Buthidae and Scorpionidae with 16 genera and 25 species. In Iran, similar to other parts of the world, there are a few known species of scorpions responsible for severe envenoming. Mesobuthus eupeus is the most common species in Iran. Its venom contains several toxin fractions which can affect the ion...

Equine hyperimmune serum protects mice against Clostridium difficile spore challenge

Clostridium (C.) difficile is a common cause of nosocomial diarrhea in horses. Vancomycin and metronidazole have been used as standard treatments but are only moderately effective, which highlights the need for a novel alternative therapy. In the current study, we prepared antiserum of equine origin against both C. difficile toxins A and B as well as whole-cell bacteria. The toxin-neutralizing ...
