Variations in cervico-vaginal microbiota among HPV-positive and HPV-negative asymptomatic women in Peru

BMC Res Notes. 2021 Jan 6;14(1):4. doi: 10.1186/s13104-020-05422-6.

Abstract

Objective: To characterize the cervicovaginal microbiota of HPV-positive and HPV-negative asymptomatic Peruvian women, by identifying the presence of 13 representative bacteria genus.

Results: A total of 100 HPV-positive and 100 HPV-negative women were matched by age for comparison of microbiota. The following bacteria were more frequently identified in HPV-positive patients compared to HPV-negative: Eubacterium (68 vs 32%), Actinobacteria (46 vs 33%), Fusobacterium (11 vs 6%) and Bacteroides (20 vs 13%). A comparison between high-risk and low-risk genotypes was performed and differences were found in the detection of Actinobacteria (50 vs 33.33%), Bifidobacterium (50 vs 20.83%) and Enterococcus (50 vs 29.17%).

Keywords: Cervical cancer; HPV; Human papillomavirus; Microbiota; PCR; Peru.
