The purpose of this research was to assess the antimicrobial activity of rosemary essential oil (Rosmarinus officinalis) against the growth of Streptococcus mutans ATCC 25175 "in vitro". For the microbiological analysis, 100% rosemary essential oil was used and the agar well diffusion method was applied. Thirty Petri dishes with Muller Hinton agar were prepared, each containing a 6 mm diameter well saturated with rosemary essential oil and 0.12% chlorhexidine (DENTODEX®). The samples were incubated at 37°C and were only removed to measure and record the bacterial inhibition halos after 72 and 168 hours. The essential oil was compared with 0.12% chlorhexidine gluconate as a positive control for Streptococcus mutans ATCC 25175, and sterile distilled water was used as the negative control. The data were processed using SPSS, and the T-test was applied. The study concluded that Rosmarinus officinalis (rosemary) essential oil exhibited "in vitro" antibacterial activity against Streptococcus mutans ATCC 25175 at 72 hours, and 0.12% chlorhexidine showed greater antibacterial activity than the essential oil against this bacterial strain at 168 hours.

The objective of this research was to assess the antibacterial activity of the essential oil of Cinnamomum zeylanicum (cinnamon) compared to 0.12% chlorhexidine against Streptococcus mutans ATCC 25175 "in vitro". The study was experimental, prospective, and longitudinal. The essential oil was obtained using the steam distillation method from the bark of Cinnamomum zeylanicum (cinnamon). For microbiological analysis, the essential oil was used at 100%, and the well-agar diffusion method was applied. Thirty Petri dishes with Muller Hinton agar were prepared, each with a 6 mm diameter well saturated with cinnamon essential oil and 0.12% chlorhexidine (DENTODEX®). The samples were incubated at 37°C, and inhibition zones were measured and recorded at 72 and 120 hours. The essential oil was compared to 0.12% chlorhexidine as a positive control for Streptococcus mutans ATCC 25175, with sterile distilled water as the negative control. The data were processed using SPSS, and the T-Student statistical test was applied. The study concluded that the essential oil of Cinnamomum zeylanicum (cinnamon) showed stability and antibacterial activity "in vitro" against Streptococcus mutans ATCC 25175 at 72 and 120 hours. Chlorhexidine 0.12% showed greater antibacterial activity than the essential oil at 120 hours.

Objective: To determine the prevalence of bacterial vaginosis in sex workers attending the Maternal and Child Health Center of Tahuantinsuyo Bajo, District of Independencia, from November 2014 to March 2015. Methods: The research was observational, descriptive, and cross-sectional. The population consisted of 250 sex workers, who gave informed consent and completed an epidemiological form (sociodemographic and sexual history). A vaginal discharge sample was taken, and characteristics of the secretion, amine test, and Gram staining were evaluated for the presence of clue cells. The Amsel criteria were used for diagnosis. Results: Of the sex workers, 52% presented bacterial vaginosis (all with vaginal discharge, positive amine test, and clue cells). The age group with the highest prevalence was 18 to 30 years, accounting for 26.8%. 34.8% of the sex workers with bacterial vaginosis had initiated sexual activity before 20 years old. 26.4% of those with bacterial vaginosis had 6–8 sexual partners per day. Conclusion: 52% of the sex workers presented bacterial vaginosis; the most common age group was 18 to 30 years, the age of sexual debut was younger than 20 years, and the number of sexual partners per day was 6 to 8.
