Comparative study of vulva and abdominal skin microbiota of healthy females with high and average BMI.

BMC Microbiol 2019 Jan 17;19(1):16. Epub 2019 Jan 17.

Kimberly Clark Corporation, 2100 County Rd II, Neenah, WI, 54956, USA.

Background: Obesity is known to modulate human health in a number of ways including altering the microbiome of the gut. Very few studies have examined the how obesity may affect the microbiomes of sites distant to the gut. We hypothesized that vulva and abdominal skin may be especially susceptible to body mass index (BMI)-induced alterations in biophysical properties and the microbiome due increased maceration and skin folds at those sites.

Vaginal pH measured in vivo: lactobacilli determine pH and lactic acid concentration.

BMC Microbiol 2019 Jan 14;19(1):13. Epub 2019 Jan 14.

ReProtect Inc., Baltimore, Maryland, USA.

Background: Lactic acid (protonated lactate) has broad antimicrobial activity. Vaginal lactobacilli produce lactic acid, and are known to confer protection against reproductive tract infections when they are predominant in the vaginal microbiota. Using novel ex vivo methods, we showed that cervicovaginal fluid (CVF) from women with a predominantly lactobacilli-morphotype microbiota contains significantly more lactic acid than previously thought, sufficient to inactivate reproductive tract pathogens.
