Abstract
Streptococcus agalactiae remains a major pathogen in human health, especially in neonatal infection. Detection in pregnant women is essential to initiate intrapartum antibiotic prophylaxis. This study compared the HiberGene loop-mediated isothermal amplification (LAMP) assay to culture, the reference method, for the detection of group B Streptococcus (GBS) in pregnant women. This was a prospective multicenter study conducted in four French hospitals. Three hundred fifty-four non-redundant routine care vaginal swabs were analyzed by both methods, LAMP assay and culture. Clinicians and patients were blinded to the results of the LAMP assay. Three hundred thirty-seven samples presented concordant results, 15 presented discordant results, and 2 were invalid using the LAMP assay (excluded from the study). Compared to culture, the LAMP assay had a sensitivity of 87.7%, a specificity of 98%, a negative predictive value of 97.6%, and a positive predictive value of 89.3%. The HiberGene GBS LAMP assay is an easy test that possesses good performances compared with the reference method, culture. It could be used in case of emergency when a quick result is needed.
