Abstract

Urogenital infections affect millions of people every year worldwide. The treatment of these diseases usually requires the use of antimicrobial agents, and more recently, the use of probiotic lactic acid bacteria (LAB) cultures for the management of vaginal infections has been extensively studied. In this work, 11 vaginal lactobacilli isolates, previously obtained from healthy patients, were studied to screen microorganisms with probiotic properties against Candida spp. The LAB were tested for their ability of auto-aggregation, co-aggregation with C. albicans, C. glabrata, C. krusei, and C. tropicalis, adhesion to Caco-2 epithelial cells and production of lactic acid and hydrogen peroxide (H2O2). All lactobacilli isolates tested were able to auto-aggregate (ranging from 25.3% to 75.4% assessed at 4 hours of incubation) and to co-aggregate with the four Candida species into different degrees; among them L. crispatus showed the highest scores of co-aggregation. The highest amount of lactic acid was produced by L. salivarius (13.9 g/l), followed by L. johnsonii (6.5 g/l), L. acidophilus (5.5 g/l), and L. jensenii (5.4 g/l). All isolates produced H2O2, but the highest levels (3 - 10 mg/l) were observed for L. acidophilus, L. crispatus, L. gasseri, L. johnsonii, and L. vaginalis. Only L. agilis, L. jensenii, L. johnsonii and L. ruminus were able to adhere to epithelial Caco-2 cells. Among the isolates evaluated, L agilis, L. jensenii, L. johnsonii, and L. ruminus exhibited simultaneously several desirable properties as potential probiotic strains justifying future studies to evaluate their technological properties in different pharmaceutical preparations for human use.

  • Autoaggregation is the gathering of the same microorganism strains, which can create a barrier to prevent pathogen adhesion.

    “Autoaggregation is the gathering of the same microorganism strains, which can create a barrier to prevent pathogen adhesion.”

    From Aggregation and adhesion ability of various probiotic strains and Candida species: An in vitro study (2024) · cites this paper as [7]

    The Results and Discussion section reports that lactobacilli auto-aggregate and that auto-aggregation is a first step toward biofilms that help inhibit pathogen overgrowth. It does not say that auto-aggregation itself creates a barrier preventing pathogen adhesion; it links barrier formation to lactobacilli adhering to epithelial tissue, and blocking pathogens from tissue receptors to co-aggregation.

  • Previous studies have reported that the coaggregation ability of probiotic Lactobacillus strains with Candida species varied depending on the strain.

    “Previous studies have reported that the coaggregation ability of probiotic Lactobacillus strains with Candida species varied depending on the strain, however, most studies have only examined intestinal and vaginal probiotic Lactobacillus strains.7, 8, 9”
  • Coaggregation is the gathering of different microorganism strains, which can inhibit the dissemination of the pathogen to adhesion sites on host mucosal tissues.

  • Most studies have only examined intestinal and vaginal probiotic Lactobacillus strains, and there have been very few studies relating to oral probiotic strains.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
