A new report from Fujian Medical University in China presents data on the clinical characteristics and current treatment modality of preterm infants with Ureaplasma spp. infection. The study found that the prevalence of respiratory tract Ureaplasma spp. colonization in infants born at a gestational age of less than 32 weeks was 25.8%.
