Description
Tuangrat Tunvongvinis is first author on a 2026 study of a germ-killing compound from bacteria living on an ant. Social insects such as ants are useful sources of actinomycetes. These bacteria are famous for making antibiotics. A Streptomyces strain isolated earlier from the ant Polyrhachis laevissima showed potent activity, but its active compound was unknown.
The strain was identified as Streptomyces parvulus. Guided by activity tests, the team purified its compound. Lab tests identified it as actinomycin D. It acted broadly against gram-positive and gram-negative bacteria, including drug-resistant staph, and against Candida yeasts. Best growing conditions gave the highest yield after fourteen days. The work supports ant microbes as drug sources.
