Local Interest ↔ Global Impact
Premise: Involve teachers in development of inquiry-based exercises in science education that bring contemporary biomolecular techniques into their classrooms and
allow participation in actual science research

Muse of Fire: Team approach to develop 5 unique, inquiry-
based biotechnology training high school activities focused on the RIFA
Team 1 – Microecology of RIFA: Effects on local environment?
Team 2 – Toxicology: Insecticidal effects?
Team 3 – Human Health Impact: Human danger?
Team 4 – Gene Microarray: Molecular effects?

S. invicta Venom – Clinical Toxicity?
• Vast majority of stings cause:• Minor, transient pain• Local redness and
swelling with sterile pustule formation
• Small numbers have larger areas of swelling
• Very few have life-threatening allergic reactions
• Reports of massive fire ant attacks on infants and elderly in nursing homes

S. invicta Venom
•Unique among stinging insects– ~95% alkaloids and ~5% proteins
•Proteins recognized by immune system and cause allergic reactions •Potential for alkaloid toxicity unknown despite amount in venom Venom contains mixture of
several alkaloid forms – isosolenopsins – solenopsins– dehydrosolenopsins

Massive Fire Ant Stings
• Most of these cases had severe symptoms, but only one had anaphylactic symptoms.
• Adverse responses to the massive stings included:
– cardiopulmonary failure or arrest in 6 of 10 cases in the medical literature.
– death in 6 of 10 cases in the medical literature.• deShazo RD, et al. Ann Intern Med 1999; 131: 424-429.
– death in 8 of 20 total cases reported (1 of 4 infants).•Rupp MR, et al. Am J Med Sci 2006; 331: 134-138.
