Seed inoculation with plant growth promoting rhizobacteria (PGPR) is an ideal tool to supply the soil a high density of beneficial microorganisms. However, maintaining viable microorganisms major problem during seed treatment and storage. In this work, evaluation was made effect bacterial immobilization in nanofibers on stability (viability maintenance properties) two potential PGPR, Pantoea agglomerans ISIB55 Burkholderia caribensis ISIB40. Moreover, impact soybean coating...
Abstract Background Lactobacillus spp. dominating the vaginal microbiota of healthy women contribute to prevention urogenital and sexually transmitted infections. Their protective role in vagina can be mediated by cells themselves, metabolites or bacterial components, able interfere with pathogen adhesion infectivity. Vulvovaginal candidiasis (VVC) is a common genital infection, caused overgrowth opportunistic Candida including C. albicans, glabrata, krusei tropicalis . Azole antifungal...
Lactobacilli are the dominant members of healthy human vaginal microbiota and represent first defense line from pathogen infection, including vulvovaginal candidiasis. Biofilm is predominant microbial growth form in nature, formation biofilms inside body has important implications health disease. In particular, biofilm by resident desirable, as it can improve persistence influence functionality. present study, we investigated capability 16 Lactobacillus strains (belonging to crispatus,...
Abstract Citrus canker is a worldwide‐distributed disease caused by Xanthomonas citri subsp. . One of the most used strategies to control centred on copper‐based compounds that cause environmental problems. Therefore, it interest develop new manage disease. Previously, we reported ability siderophore pyochelin, produced opportunistic human pathogen Pseudomonas aeruginosa , inhibit in vitro several bacterial species, including X. The action mechanism, addressed with model bacterium...
The aim of this work was to evaluate the effects beneficial human vaginal lactobacilli (Lb) on urogenital pathogens through in vitro and vivo experiments. Co-aggregative antimicrobial properties between five Lb strains or potential (Streptococcus agalactiae, Staphylococcus aureus Candida albicans strains) were assayed. Also, associative cultures S. agalactiae performed bacterial growth, pH, lactic acid hydrogen peroxide (H2O2) determined at different times. Based results obtained, studies...
To assess the preventive effect of different intravaginal (i.va.) doses Lactobacillus reuteri CRL1324 against vaginal colonization by Group B Streptococcus (GBS) in a murine experimental model.The major virulence factors four GBS clinical isolates were determined to select most virulent strain and set up model streptococcal colonization. Later, seven 10(8) viable cells Lact. i.va. administered, prior challenge was studied. Seven lactobacilli able significantly reduce number cells, while...
The emergence of resistance to antifungal drugs has made the treatment vulvovaginal candidiasis (VVC) very challenging. Among natural substances, biosurfactants (BS) produced by Lactobacillus have gained increasing interest in counteracting Candida infections for their proven anti-adhesive properties and safety profile. In present study, liposomes (LP-BS) or coated with hyaluronic acid (HY-LP-BS) were prepared presence BS isolated from vaginal strain crispatus BC1 characterized terms size, ζ...
Vulvovaginal candidiasis (VVC) is one of the most frequent infections affecting women worldwide. Healthy vaginal microbiota dominated by lactobacilli, which form a strong defense line against pathogens. In this work, in vitro antimicrobial properties thirty Lactobacillus strains were evaluated eleven Candida clinical isolates, employing three different methods. Also, effect intravaginal (i.va.) administrations (preventive, therapeutic and preventive-therapeutic) L. reuteri CRL1324 or...
Problem Maternal Group B Streptococcus ( GBS ) colonization is a risk factor for infectious disease in newborns. One promising strategy the modulation of vaginal defense to increase host's ability combat infection. Method Study The effect intravaginal (i.va.) Lactobacillus reuteri CRL 1324 inoculation on different immune cell populations, cytokines, and immunoglobulin isotypes murine model was evaluated. Results Seven i.va. inoculations L. previous challenge showed an immunomodulatory cells...
Vaginal lactobacilli (LAB) in probiotic formulas constitute a promising alternative for microbiome reconstitution and the prevention treatment of urogenital infections. A double-blind, randomised clinical trial was conducted to assess safety LAB-gelatine capsules vaginally administered healthy sexually active women. Participants were into three groups: intervention A: Lactobacillus reuteri CRL1324, gasseri CRL1263 CRL1307; B: rhamnosus CRL1332, L. CRL1256 CRL1320; C: placebo. In survey...
The design of probiotic hygiene products for daily use is considered an adequate alternative the restoration vaginal microbiome, maintaining health, and/or preventing infections female urogenital tract. Most these are available on world market, but their efficacy and safety not sufficiently documented. One requirements to transfer novel formulas/products productive sector demonstrate innocuity absence adverse or collateral effects host, mainly assayed in experimental models. inclusion...
