Updated project metadata. Micronutrient deficiency (MND i.e., lack of vitamins and minerals) during pregnancy is a major public health concern. Historically, studies have considered micronutrients in isolation; however, MNDs rarely occur alone. Furthermore, the impact of co-occurring MNDs on public health, mainly in shaping mucosal colonization by pathobionts from Enterobacteriaceae family, remain undetermined due to lack of relevant animal models.
