Abstract

Objective: To analyze the presence and persistence of E6/E7 HPV58 variations in women with prevalent HPV58 infection, with normal cytology, who belong to the Bogotá, Colombia cohort.
Methods: Cervical cytobrush was used on 34 HPV58 women, with normal cytology, who are part of the cohort base line; respective follow was performed. The HPV58 E67/E7 region was broadened by using E6F1-E7R1 and E7P1-E7P2 indicators. Variation analysis was carried out with automatic direct sequencing. HPV58 sequence reference was used to compare the sequences that had been obtained.
Results: In 27/34 samples, E6/E7 variations of HPV58 were successfully detected. A total of five different variations were detected, two of which had never been reported before (A169/T307/A694/G744/A761 and T307/ A694/G744/A761/G763). Elimination analysis revealed that 75% of variations had been eliminated with in two years of follow up, and that all variation had been eliminated at the end of six years of followup.
Conclusions: Two new variations of universal phylogenetic and epidemiologic noteworthiness were reported
