Pairs of ovaries from five armadillos were collected during a routine epidemiological survey of leprosis (three healthy and two infected females). Ovaries weighed approximately 0.06 kg, representing a gonadosomatic index of 6.9 \u00b1 0.8%. The mean ovarian follicular population was 15,567.2 preantral follicles per ovarian pair. For most females, follicular population was mainly composed of primordial follicles. No major histological ovarian parameter was affected by M. leprae infection. All females presented high rates of follicular degeneration, regardless of M. leprae infection. In conclusion, we present original particularities regarding the qualitative and quantitative characteristics of the ovarian population of juvenile six-banded armadillos.<\/jats:p>","DOI":"10.3390\/vetsci12010037","type":"journal-article","created":{"date-parts":[[2025,1,9]],"date-time":"2025-01-09T07:00:47Z","timestamp":1736406047000},"page":"37","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Characterization of the Population of Ovarian Preantral Follicles in Juvenile Six-Banded Armadillos Infected or Not by Mycobacterium leprae"],"prefix":"10.3390","volume":"12","author":[{"given":"Gabriela L.","family":"Lima","sequence":"first","affiliation":[{"name":"Federal Institute of Education, Science and Technology of the Cear\u00e1 State\u2014IFCE, Crato 63100, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreza V.","family":"Brasil","sequence":"additional","affiliation":[{"name":"Laboratory on Animal Germplasm Conservation, Federal University of Semiarid Region\u2014UFERSA, Mossor\u00f3 59600, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreia M.","family":"Silva","sequence":"additional","affiliation":[{"name":"Laboratory on Animal Germplasm Conservation, Federal University of Semiarid Region\u2014UFERSA, Mossor\u00f3 59600, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3922-1428","authenticated-orcid":false,"given":"Jo\u00e3o Marcelo A. de P.","family":"Antunes","sequence":"additional","affiliation":[{"name":"Veterinary Hospital, Federal University of Semiarid Region\u2014UFERSA, Mossor\u00f3 59600, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pierre","family":"Comizzoli","sequence":"additional","affiliation":[{"name":"Smithsonian\u2019s National Zoo and Conservation Biology Institute, Washington, DC 20008, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6027-1062","authenticated-orcid":false,"given":"Alexandre R.","family":"Silva","sequence":"additional","affiliation":[{"name":"Laboratory on Animal Germplasm Conservation, Federal University of Semiarid Region\u2014UFERSA, Mossor\u00f3 59600, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,9]]},"reference":[{"key":"ref_1","first-page":"61","article-title":"Assisted reproduction in six-banded armadillos (Euphractus sexcinctus): Peculiarities and challenges","volume":"39","author":"Silva","year":"2015","journal-title":"Rev.
