Resumen
Background: Vaginal infection is the commonest cause of genital symptoms and has obstetric and gynecological implications. Aim: To compare the Nugent and Spiegel methods for the diagnosis of bacterial vaginosis (BV) and to analyze discordant specimens using Ison and Hay (Ison/Hay) criteria. Material and Methods: After discarding cases with Candidiasis, defi cient specimens or those lacking bacteria, a total of 348 Gram-stained smears vaginal specimens received for the diagnosis of BV, were analyzed. Results: Vaginal microbiota was classifi ed as normal in 203 and 237 samples (58 and 68% of samples), according to Nugent and Spiegel criteria, respectively. One hundred and fi ve (30%) and 111 samples (32%), were classifi ed as VB according to Nugent and Spiegel criteria, respectively. Both criteria were concordant in 308 samples (88.5%). The 40 (11.5%) discordant specimens were classifi ed as intermediate microfl ora by the Nugent system and as normal or BV by Spiegel. Among these, the Is
