Ants live under ideal microclimatic conditions for the development of microorganisms. As mechanisms to ensure the health of the colony and as a defense strategy, these insects developed exocrine glands that work in the production of antibiotics (chemical defense) and in the immune defense of the colony. This study aimed to describe the state-of-the-art on extraction methods, chemical characterization and the antibiotic potential of glandular secretions of ants. This is a review of the scientific literature between 1989 and 2017. A total of 52 articles were selected. These addressed the behavior, chemical characterization, the antimicrobial effect and evaluated methods of extraction. The most investigated genera are Atta, Acromyrmexand Crematogaster. The glands most reported in the articles involving extraction of secretions were Dufour, mandibular and metapleural. The most reported methods of extraction were gland maceration and extraction with (organic) solvents and direct extraction of the gland. Most studies evaluated secretions with respect to ant behavior. There is a paucityin the literature about the chemical characterization of most glandular secretions of ants, as well as for most taxa. The same deficiency is observed with regard to prospecting the antibiotic and antifungal potential of these secretions. for most taxa. The same deficiency is observed with regard to prospecting the antibiotic and antifungal potential of these secretions.

The ant Paraponera clavata (Fabricius, 1775) is the only extant species of Paraponerinae and is widely distributed in Brazilian forests. Aspects of its biology are documented extensively in the literature; however, knowledge of P. clavata internal morphology, specifically of exocrine glands, is restricted to the venom apparatus. The objective of this study was to describe the mandibular gland morphology of P. clavata workers. The mandibular gland is composed of a reservoir connected to a cluster of Type III secretory cells with cytoplasm rich in mitochondria and lipid droplets, similar to that of other ants. Notably, the glandular secretion is rich in protein and has a solid aspect. This is the first morphological description of the mandibular gland of P. clavata. Research Highlights This study presents the morphological description of the mandibular gland of Paraponera clavata (Hymenoptera: Paraponerinae). Singular characteristics of the gland are described: the glandular secretion is rich in protein and has a solid aspect.

Soil actinobacteria inhibit antagonistic fungi of leafcutter ant colonies

et al. 2021

Founder females of the leaf-cutting ant species Atta sexdens experience high mortality during the founding and establishment of their colonies. The foundation site is crucial for the success of a new colony. In this study, we isolated and identified actinobacteria from fungus garden chambers of A. sexdens colony growth in soils from (1) forested areas without leafcutter ant nests and (2) open ground areas close to leafcutter ant nests. The inhibitory effect of these isolates on pathogenic fungi and the mutualistic fungus cultivated by leafcutter ants was evaluated. The 16S rRNA gene sequences were employed to identify nine selected actinobacteria species found in the soil: Streptomyces (6), Nocardia (2), and Kitasatospora (1). One Streptomyces and one Kitasatospora isolate inhibited all the tested fungi. Since there is no evidence of actinobacteria cultivation in the workers' cuticle of the Atta genus, our results corroborate the hypothesis that these workers may establish temporary adaptive symbiosis with soil microorganisms that produce antibiotic substances, living in some parts of their nest, or even inside their bodies.
