    Study Notes

    Ant Surgical Procedures

    • Florida carpenter ants perform life-saving surgeries on injured nestmates, a behavior never before observed in non-human animals.
    • These ants, native to the southern US, live in rotting wood and are vulnerable to injuries while defending territories.
    • Unlike other ant species, Florida carpenter ants lack antimicrobial glands.

    Experimental Procedure

    • Researchers (Dr. Erik Frank and team, University of Würzburg) injured 100 ants, creating wounds on their femurs (upper leg) and tibiae (lower leg).
    • The wounds were exposed to common soil bacteria.
    • Injured ants were divided into two groups:
      • One group left isolated to fend for themselves.
      • The other group was returned to their nests.

    Surgical Treatments

    • Nestmates responded swiftly to the injured ants, cleaning the wounds with their mouths.
    • Treatment differed based on the location of the injury:
      • Femur injuries: Ants carefully amputated the entire leg, a procedure lasting at least 40 minutes involving multiple ants (surgeons). This high-removal rate led to a 90% survival rate of treated ants, compared to only 40% for isolated ants with femur injuries.
      • Tibia injuries: Ants simply licked the wounds to remove bacteria, leading to a 75% survival rate of treated ants, compared to only 10% of isolated ants with tibia injuries.

    Mechanism of Treatment Decision

    • The scientists believe treatment decisions (amputation versus cleaning) relate to the flow of hemolymph (ant blood).
    • Femurs have more muscle tissue slowing hemolymph flow, preventing bacteria spread, allowing ample time for amputation.
    • Tibiae have less muscle, allowing easier, faster bacteria spread, thus necessitating only cleaning.

    Conclusion and Further Research

    • The ants can diagnose an injury's condition (infected or not) and tailor treatment accordingly for extended periods. This advanced medical system is comparable to human medical care.
    • The study was published in Current Biology on July 2, 2024.
    • Researchers aim to explore if other ant species exhibit similar surgical aid.
