ABSTRACT=<p><bold>Objectives:</bold> We aim to assess the correlation of multidrug-resistant <italic>Staphylococcus aureus</italic> (MDR <italic>S. aureus</italic>) carriage between mothers and their newborn infants.</p><p><bold>Materials and Methods:</bold> We conducted a prospective cohort study of mothers and their newborn infants in two hospitals in Shenzhen, China, from August to November 2015. We collected demographic and clinical information from mothers and newborn infants by face-to-face questionnaires and medical datasets. Serial swabs were collected from mothers and their newborn infants for further experiments. Maternal-infant correlation was assessed using the Poisson regression model.</p><p><bold>Results:</bold> The prevalence of MDR <italic>S. aureus</italic> vaginal carriage in mothers was 4.7% (86/1834). The incidence of MDR <italic>S. aureus</italic> carriage in newborn infants was 1.3% (23/1834). The adjusted relative risk and 95% confidence interval of maternal-infant MDR <italic>S. aureus</italic> carriage was 7.63 (2.99–19.49). Six MDR <italic>S. aureus</italic> maternal-infant pairs were concordant. The phenotypic and molecular characteristics of MDR <italic>S. aureus</italic> isolates were similar between mothers and their newborn infants.</p><p><bold>Conclusion:</bold> MDR <italic>S. aureus</italic> vaginal carriage in mothers was associated with an increased risk for MDR <italic>S. aureus</italic> carriage in their newborn infants.</p>
