We sampled different rodent communities within and around human settlements in Northern Senegal, an area subjected to major environmental transformations associated with global changes. Herein, we conducted an epidemiological study on their bacterial communities. One hundred and seventy-one (171) invasive and native rodents were captured, 50 from outdoor trapping sites and 121 rodents from indoor habitats, consisting of five species. The DNA of thirteen pathogens was successfully screened on the rodents' spleens. We found: 2.3% of spleens positive to Piroplasmida and amplified one which gave a potentially new species Candidatus "Theileria senegalensis"; 9.35% of Bartonella spp. and amplified 10, giving three genotypes; 3.5% of filariasis species; 18.12% of Anaplasmataceae species and amplified only 5, giving a new potential species Candidatus "Ehrlichia senegalensis"; 2.33% of Hepatozoon spp.; 3.5% of Kinetoplastidae spp.; and 15.2% of Borrelia spp. and amplified 8 belonging all to Borrelia crocidurae. Some of the species of pathogens carried by the rodents of our studied area may be unknown because most of those we have identified are new species. In one bacterial taxon, Anaplasma, a positive correlation between host body mass and infection was found. Overall, male and invasive rodents appeared less infected than female and native ones, respectively. specialized pathogens host zoonotic disease rodents Bartonella Borrelia crocidurae Anaplasmataceae Piroplasmida Hepatozoon 052 080 9 3 art. 202 [21 p.] 2020 https://www.documentation.ird.fr/hor/fdi:010078903 10.3390/pathogens9030202 [F B010078903] https://www.documentation.ird.fr/hor/fdi:010078903 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers20-04/010078903.pdf IRD - Base Horizon / Pleins textes 2020-05-19 2025-02-24 fdi:010078903 fre
