Lactobacillus rhamnosus intake can prevent the development of Candidiasis.

Objective: This study aimed to investigate the influence of Lactobacillus rhamnosus intake on the development of candidiasis and cytokines release.

Material And Methods: Candida suspensions were inoculated into the oral cavity of experimentally immunosuppressed mice for candidiasis induction. The animals were divided into experimental groups: candidiasis with no probiotic intake (F), candidiasis with probiotic intake during Candida inoculation (FP), and candidiasis with probiotic intake 14 days before inoculation with Candida (FPP); and control groups: (C), (CP), and (CPP) without inducing candidiasis with probiotic intake in the same manner as groups F, FP, and FPP, respectively.

Prevalence and Sensitivity of Bacilli and Pseudomonas in the Newborn's Oral Cavity.

The aim of this study was to isolate Enterobacteria and Pseudomonas from the oral cavity of hospitalized newborns (NB) and determine their prevalence and the sensitivity profile to most commonly used antibiotics for this age group. Samples from the oral cavity of NB from 24 to 48 h age were collected using swabs. The samples were inoculated on MacConkey agar, incubated and the colonies counted and identified.

[Lactobacillus rhamnosus may change the virulence of Candida albicans].

Purpose: To investigate the influence of Lactobacillus rhamnosus in the expression of virulence factors of Candida albicans in vitro.

Methods: A suspension of L. rhamnosus was initially grown in MRS agar.

Stability of antimicrobial activity of peracetic acid solutions used in the final disinfection process.

The instruments and materials used in health establishments are frequently exposed to microorganism contamination, and chemical products are used before sterilization to reduce occupational infection. We evaluated the antimicrobial effectiveness, physical stability, and corrosiveness of two commercial formulations of peracetic acid on experimentally contaminated specimens. Stainless steel specimens were contaminated with Staphylococcus aureus, Escherichia coli, Candida albicans, blood, and saliva and then immersed in a ready peracetic acid solution: 2% Sekusept Aktiv (SA) or 0.

[Sensitivity profile of Staphylococcus spp. and Streptococcus spp. isolated from toys used in a teaching hospital playroom].

Objective:: To evaluate the presence of microorganisms of the genus and on toys in the playroom of a teaching hospital, as well to as analyze the antimicrobial resistance from isolated strains.

Methods:: Samples were collected from 60 toys, using wet swabs, soon after being used by the children. The samples were inoculated in enriched and selective agar for isolation and later identification of the microorganisms.

Candida spp. adherence to oral epithelial cells and levels of IgA in children with orthodontic appliances.

Adhesion and colonization of the oral cavity by Candida albicans is an initial step in candidosis. Orthodontic and other oral appliances seem to favor candidal presence. The aim of this work was to compare the presence of Candida species in saliva, their adherence to oral epithelial cells, and the levels of anti–C.

Effects of probiotic bacteria on Candida presence and IgA anti-Candida in the oral cavity of elderly.

Imbalance in the resident microbiota may promote the growth of opportunistic microorganisms, such as yeasts of Candida genus and the development of diseases, especially in aged people. This study evaluated whether the consumption of the probiotic Yakult LBz(®) (Lactobacillus casei and Bifidobacterium breve) was able to influence on the specific immunological response against Candida and on the presence of these yeasts in the oral cavity of 42 healthy aged individuals. Saliva samples were collected before and after the probiotic use for 30 days, 3 times a week.

Influence of consumption of probiotics on presence of enterobacteria in the oral cavity.

Clinical benefits of probiotics have been clearly reported in different gastrointestinal disorders, many of them caused by enterobacteria. The oral cavity is a port of entry and can be an important reservoir of these microorganisms. This work evaluated whether consumption of probiotics was able to influence the presence of enterobacteria in the oral cavity and the specific secretory response against these microorganisms.

Influence of probiotics on Candida presence and IgA anti-Candida in the oral cavity.

Probiotics are defined as microorganisms that promote benefits to host health, mainly by regulating resident microbiota. Disequilibrium in microbiota can favor the growth of opportunist microorganisms and the development of pathologies, like candidosis caused by yeasts of the Candida genus. This work evaluated whether probiotics consumption was able to influence a specific immunological response to Candida and the presence of these yeasts in the oral cavity.

[Relationship between Candida in vaginal and oral mucosae and salivary IgA].

Purpose: to correlate the presence of yeast from the Candida genus in the oral and vaginal cavity of women with and without vulvovaginal candidiasis (VVC), with secretor IgA levels (IgAs) present in the saliva.

Methods: among the 51 women included, 13 presented VVC and 38 were the Control Group. An amount of 2.

[Evaluation of surface disinfectants utilized in dentistry].

Surface disinfection is a procedure carried out on the external parts of the dental equipment as well as on other items of the dental office. The aim of this study was to analyze the efficacy of 4 surface disinfectants utilized in dentistry: 77 degrees GL alcohol, phenolic compound (Duplofen), iodophor (PVP-I) and 77 degrees GL alcohol with 5% of chlorhexidine. Four surfaces of the equipment were analyzed in the study (the carter, the washbasin for hand-washing, the headrest of the chair and the external surface of the reflector), and the spray-wipe-spray procedure was carried out.
