Abstract
Between 2018 and 2023, a genomic study was conducted in a military camp in Djibouti to investigate the molecular epidemiology of Panton-Valentine Leukocidin-producing Staphylococcus aureus. Among 43 isolates, Sequence Type 152 was predominant (72%), mainly associated with spa types t355 and t4235. Core-genome Multi-Locus Sequence Typing revealed two concurrent transmission dynamics: localized inter-human outbreaks and repeated introductions from external sources. Comparative genomics with other African Sequence Type 152 isolates showed similar levels of diversity, suggesting a widespread continental dissemination. These findings highlight the importance of genomic surveillance to better understand and control the spread of this virulent lineage in Africa.
期刊介绍：
PLOS Neglected Tropical Diseases publishes research devoted to the pathology, epidemiology, prevention, treatment and control of the neglected tropical diseases (NTDs), as well as relevant public policy.
The NTDs are defined as a group of poverty-promoting chronic infectious diseases, which primarily occur in rural areas and poor urban areas of low-income and middle-income countries. Their impact on child health and development, pregnancy, and worker productivity, as well as their stigmatizing features limit economic stability.
All aspects of these diseases are considered, including:
Pathogenesis
Clinical features
Pharmacology and treatment
Diagnosis
Epidemiology
Vector biology
Vaccinology and prevention
Demographic, ecological and social determinants
Public health and policy aspects (including cost-effectiveness analyses).
