In this study, the genetic relationship and the population structure of western Mediterranean basin native sheep breeds are investigated, analyzing Maghrebian, Central Italian, and Venetian sheep with a highly informative microsatellite markers panel. The phylogeographical analysis, between breeds' differentiation level (Wright's fixation index), gene flow, ancestral relatedness measured by molecular coancestry, genetic distances, divergence times estimates and structure analyses, were revealed based on the assessment of 975 genotyped animals. The results unveiled the past introduction and migration history of sheep in the occidental Mediterranean basin since the early Neolithic.

This study shows, for the first time, natural infection among spp. in an endemic region of Tataouine, South Tunisia. To better characterize the transmission cycles in this complex focus of mixed transmission, detection and species identification were performed by direct examination, internal transcribed spacer-1 (ITS1)-PCR-restriction fragment length polymorphism (RFLP), and sequencing of (.

Cutaneous leishmaniasis (CL) remains one of the world's most prevalent neglected diseases, particularly in developing countries. Identification of the involved species is an important step in the diagnosis and case management process. In this study, we tested simple, rapid, and highly sensitive loop-mediated isothermal amplification (LAMP) assays for DNA species-specific detection from cutaneous lesions.

Article Synopsis
  • Leishmaniasis, caused by various Leishmania species, is a significant public health issue in Tunisia, manifesting primarily as cutaneous leishmaniasis across different regions.
  • Research identified *Psammomys obesus* as a known reservoir for *L. major*, while the role of *P. vexillaris* as a potential reservoir remains unexplored.
  • Through analysis of rodent samples, the study discovered infections in both *P. obesus* and *P. vexillaris* with multiple Leishmania species, highlighting the possible epidemiological significance of these rodent species in the spread of leishmaniasis.
