This 10-year study from Serbia examined vaginal yeast infections in nearly 2,200 pregnant women. Researchers found that yeast infections occurred in about 48% of symptomatic pregnant women, with Candida albicans being the most common cause. Importantly, the study discovered that other yeast species are increasingly important in these infections, and new identification methods (MALDI-TOF MS) revealed these species are often misidentified by traditional laboratory methods. The findings suggest that accurate yeast identification is essential for choosing the right treatment during pregnancy.
