Popis: Abstract Background Ticks are arthropods that can host and transmit pathogens to wild animals, domestic animals, and even humans. The microbiome in ticks is an endosymbiotic, pathogenic and is yet to be fully understood. Results Adult male Amblyomma scalpturatum (A. scalpturatum) and Amblyomma ovale (A. ovale) ticks were collected from Tapirus terrestris (T. terrestris) captured in the rural area of San Lorenzo Village, and males Amblyomma sabanerae were collected from Chelonoidis denticulate (C. denticulate) of the Gamita Farm in the Amazon region of Madre de Dios, Peru. The Chao1 and Shannon–Weaver analyses indicated a greater bacterial richness and diversity in male A. sabanerae (Amblyomma sabanerae; 613.65–2.03) compared to male A. scalpturatum and A. ovale (A. scalpturatum and A. ovale; 102.17–0.40). Taxonomic analyses identified 478 operational taxonomic units representing 220 bacterial genera in A. sabanerae and 86 operational taxonomic units representing 28 bacterial genera in A. scalpturatum and A. ovale. Of the most prevalent genera was Francisella (73.2%) in A. sabanerae, and Acinetobacter (96.8%) in A. scalpturatum and A. ovale to be considered as the core microbiome of A. sabanerae and A. scalpturatum/A. ovale respectively. Conclusions We found a high bacterial diversity in male of A. sabanerae collected from C. denticulata showed prevalence of Francisella and prevalence of Acinetobacter in male A. scalpturatum and A. ovale collected from T. terrestris. The greatest bacterial diversity and richness was found in males A. sabanerae. This is the first bacterial metagenomic study performed in A. scalpturatum/A. ovale and A. sabanerae collected from T. terrestris and C. denticulata in the Peruvian jungle.
