Abstract
The scorpions, characterized by venomous stingers, possess a diverse array of chemicals in their venom, with medically significant species belonging to families like Buthidae. In Mexico, Centruroides suffusus and Centruroides vittatus coexist, with C. suffusus considered medically important due to its highly toxic venom. This study compares their physiology, focusing on microbiome and metabolome analysis. The metabolomic profiling (12 amino acids and 28 acylcarnitines) reveals significant differences between the two species, hinting at metabolic and ecological variations. Ornithine (ORN) and arginine (ARG) were the most abundant in C. vittatus, while tyrosine (TYR) was the most abundant amino acid molecule in C. suffusus. The microbiome analysis (by Next-Generation Sequencing of the 16S ribosomal gene) indicates similarities in gut bacteria composition between the two species (Phyla: Actinobacteria, Bacteroidetes, Cyanobacteria, Firmicutes, Proteobacteria and Tenericutes).
