Bovine tuberculosis is a chronic disease of economic importance in livestock, but may also infect wild animals and occasionally humans. Its principal infective agent is Mycobacterium bovis. The present study was Undertaken to examine the possible involvement of wildlife in the M. bovis life cycle in the Pantanal and to assess their potential role as a wild animal reservoir for this disease. DNA samples were obtained from 14 wild animals, namely 4 pampas deer (Ozotoceros bezoarticus), 9 feral pigs (Sus scrofa), and 1 coati (Nasua nasua).Aregion of the hsp65 gene, present in allmycobacteria, was amplified and seven species of Mycobacterium were identified. Mycobacterium avium was present in 50 % of the samples and in all three animal species. Unsurprisingly, several non-tuberculosis mycobacteria species, such as Mycobacterium saskatchewanense, Mycobacterium parafinicum, and Mycobacterium parascrofulaceum were also detected.One sample from a deer exhibited high sequence similarity to M. bovis reference strains, which was confirmed through analysis using a 24-locus MIRU-VNTR genotyping. The results highlight the need for targeted M. bovis surveillance. |

Amazonian Dark Earths (ADEs) are unusually fertile soils characterised by elevated concentrations of microscopic charcoal particles, which confer their distinctive colouration. Frequent occurrences of pre-Columbian artefacts at ADE sites led to their ubiquitous classification as Anthrosols (soils of anthropic origin). However, it remains unclear how indigenous peoples created areas of high fertility in one of the most nutrient-impoverished environments on Earth. Here, we report new data from a well-studied ADE site in the Brazilian Amazon, which compel us to reconsider its anthropic origin. The amounts of phosphorus and calcium - two of the least abundant macronutrients in the region - are orders of magnitude higher in ADE profiles than in the surrounding soil. The elevated levels of phosphorus and calcium, which are often interpreted as evidence of human activity at other sites, correlate spatially with trace elements that indicate exogenous mineral sources rather than in situ deposition. Stable isotope actios of neodymium, strontium, and radiocarbon activity of microcharcoal particles also indicate exogenous inputs from alluvial deposition of carbon and mineral elements to ADE profiles, beginning several thousands of years before the earliest evidence of soil management for plant cultivation in the region. Our data suggest that indigenous peoples harnessed natural processes of landscape formation, which led to the unique properties of ADEs, but were not responsible for their genesis. If corroborated elsewhere, this hypothesis would transform our understanding of human influence in Amazonia, opening new frontiers for the sustainable use of tropical landscapes going forward.
