The African Matabele ants are often injured in fights with termites. Their conspecifics recognize when the wounds become infected and initiate antibiotic treatment.
The Matabele ants (Megaponera analis), which are widespread south of the Sahara, have a narrow diet: They only eat termites. Their hunting expeditions are dangerous because termite soldiers defend their conspecifics – and use their powerful mandibles to do so. It is therefore common for ants to be injured while hunting.
If the wounds become infected, there is a significant survival risk. However, Matabele ants have developed a sophisticated healthcare system: they can distinguish between non-infected and infected wounds and treat the latter efficiently with antibiotics they produce themselves. This is reported by a team led by Dr Erik Frank from Julius-Maximilians-Universität (JMU) Würzburg and Professor Laurent Keller from the University of Lausanne in the journal Nature Communications.
