Overview study on Mycobacterium lepromatosis--the "new" species of leprosy-- by @marialopopolo.bsky.social Charlotte Avanzi, & @nrascovan.bsky.social: onlinelibrary.wiley.com/doi/10.1002/.... Important observations on the clinical implications of these historical findings. #OneHealth #histmed #aDNA
Lopopolo et al. 2026, statement on clinical significance of establishing M. lepromatosis' historical depth and geographic distribution:
"From a biomedical standpoint, the most immediate implication of these findings is that M. lepromatosis is not a recent or geographically marginal agent, but a deeply diversified pathogen whose lineages reflect long-term persistence and dispersal across the Americas. This matters because deep genomic divergence, within M. lepromatosis and between M. lepromatosis and M. leprae, can plausibly translate into phenotypic differences relevant to clinical care, including variation in virulence, immune recognition, host range, and possibly response to treatment."

🧬 Two pathogens, one disease. Leprosy cannot be understood as a single-pathogen disease. Understanding this duality is critical for modern case detection, surveillance, and long-term control strategies. A commentary with @nrascovan.bsky.social and @avanzich.bsky.social #Leprosy #OneHealth #aDNA
