Proposal of a new cutoff for Nugent criteria in the diagnosis of bacterial vaginosis.

Objectives: Treatment for lower genital tract infections is the major demand for gynecological services in public and private health centers in Brazil. The aims of this study were to evaluate the diagnostic resources proposed by Amsel, comparing them with the microflora evaluation by the Nugent score and thus propose a new cutoff point in this rating score, showing the complementarity of both diagnostic criteria.

Methods: A total of 136 female patients aged between 18 and 69years were evaluated and had their vaginal discharge samples collected.
