Comprehensive Genomic Characterization of Antibiotic Resistance, Virulence, and Clonality in Salmonella Isolates from Wild Animals in Algeria.
This study investigated Salmonella spp. in wild animals in Algeria, focusing on their prevalence, serotypes, antibiotic resistance, and virulence profiles. From fecal samples collected between May 2021 and June 2022, 1.9% showed Salmonella shedding. The identified serotypes included S. Bredeney, S. Enteritidis, S. Altona, and S. Virchow. Except for S. Altona, all isolates were resistant to quinolones, with S. Bredeney strains, exhibiting multidrug resistance. Whole-genome sequencing revealed various resistance genes and mutations in gyrA or parC genes. Additionally, plasmids IncX1 and ColpVC were detected in several isolates. A comprehensive analysis identified 201 virulence genes. These findings contribute to understanding Salmonella in wild animal populations and their potential impact on public health.
期刊介绍：
EcoHealth aims to advance research, practice, and knowledge integration at the interface of ecology and health by publishing high quality research and review articles that address and profile new ideas, developments, and programs. The journal’s scope encompasses research that integrates concepts and theory from many fields of scholarship (including ecological, social and health sciences, and the humanities) and draws upon multiple types of knowledge, including those of relevance to practice and policy. Papers address integrated ecology and health challenges arising in public health, human and veterinary medicine, conservation and ecosystem management, rural and urban development and planning, and other fields that address the social-ecological context of health. The journal is a central platform for fulfilling the mission of the EcoHealth Alliance to strive for sustainable health of people, domestic animals, wildlife, and ecosystems by promoting discovery, understanding, and transdisciplinarity.
The journal invites substantial contributions in the following areas:
One Health and Conservation Medicine
o Integrated research on health of humans, wildlife, livestock and ecosystems
o Research and policy in ecology, public health, and agricultural sustainability
o Emerging infectious diseases affecting people, wildlife, domestic animals, and plants
o Research and practice linking human and animal health and/or social-ecological systems
o Anthropogenic environmental change and drivers of disease emergence in humans, wildlife, livestock and ecosystems
o Health of humans and animals in relation to terrestrial, freshwater, and marine ecosystems
Ecosystem Approaches to Health
o Systems thinking and social-ecological systems in relation to health
o Transdiiplinary approaches to health, ecosystems and society.
