Tissue sections from 237 nine-banded armadillos (Dasypus novemcinctus) from 51 central Texas counties were examined microscopically for acid-fast bacilli and/or lesions of leprosy. Neither were found. A review of the literature relative to the incidence of leprosy from armadillos in Texas indicates that residents of counties along the Texas Gulf Coast may be at risk of contracting leprosy by handling infected armadillos or their tissues.

We found Mycobacterium leprae, the most common etiologic agent of Hansen disease or leprosy, in tissues from 9 (18.75%) of 48 nine-banded armadillos (Dasypus novemcinctus) collected across continental Ecuador. Finding evidence of a wildlife reservoir is the first step to recognizing leprosy zoonotic transmission pathway in Ecuador or elsewhere.

Article Synopsis
- * Used DNA extraction and SYBR green real-time PCR to detect pathogens, finding M. leprae DNA in 32 of the armadillos, predominantly in the species D. novemcinctus.
- * M. lepromatosis was not found in any samples, highlighting the need to study environmental factors and animal contact contributing to leprosy transmission in endemic regions.

Article Synopsis
- * It highlights evidence of possums, cattle, and armadillos as key reservoirs for Buruli ulcer, tuberculosis, and leprosy respectively, with implications for zoonotic transmission to humans.
- * The study emphasizes the need for further research and public health measures to address the complex transmission routes and control efforts for these diseases.
Seroprevalence of Leprosy in Nine-Banded Armadillos (Dasypus novemcinctus) from Tennessee, USA, 2021-22.

The nine-banded armadillo (Dasypus novemcinctus) is currently considered an invasive species in parts of its range in the USA, and this range continues to expand to the north and east. Nine-banded armadillos are one of a handful of mammals known to contract leprosy (also known as Hansen's disease); range expansion thus leads to public health concerns about whether this might increase human exposure to infected animals. We collected blood samples from 61 road-killed armadillos over two summers (2021 and 2022) in Tennessee, a US state near the northern extreme of the species' current range, and screened them for exposure to Mycobacterium leprae, the causative agent of leprosy.
