Lactobacillus crispatus M247: Characteristics of a Precision Probiotic Instrument for Gynecological and Urinary Well-Being

Abstract

The altered patterns of a microbial population colonizing an organ are increasingly recognized as a relevant item in human disease pathogenesis. The female urogenital tract is no exception, as some vaginal microbiota patterns, named community state types (CSTs), and urinary tract microbiota patterns, named urotypes (UTs), have been linked to viral, inflammatory, and gestational diseases. Treating these conditions is an issue, as antibiotic therapies alone are not always effective. Lactobacillus crispatus M247 is a strain with good intestinal and vaginal adhesion capability, combined with local antibacterial and anti-inflammatory properties; this strain also has proven nontransferable resistance to antibiotics commonly used in female genital tract infections, such as metronidazole. Lactobacillus crispatus M247 could, therefore, be considered as a potential add-on therapy to antibiotics in vaginal tract infections, with the aim to restore a favorable microbiota pattern.
