Probiotics in Cosmetic and Personal Care Products: Trends and Challenges.

Probiotics, defined as "live microorganisms that, when administered in adequate amounts, confer a health benefit on the host," are becoming increasingly popular and marketable. However, too many of the products currently labelled as probiotics fail to comply with the defining characteristics. In recent years, the cosmetic industry has increased the number of products classified as probiotics. While there are several potential applications for probiotics in personal care products, specifically for oral, skin, and intimate care, proper regulation of the labelling and marketing standards is still required to guarantee that consumers are indeed purchasing a probiotic product. This review explores the current market, regulatory aspects, and potential applications of probiotics in the personal care industry.

The Development of High-Quality Multispecies Probiotic Formulations: From Bench to Market.

Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. To date, there is an increasing number of commercially available products containing probiotics on the market. Probiotics have been recommended by health care professionals for reasons ranging from their long-term immunomodulatory effects to proven benefits in the management of different health conditions. For probiotic products, there are several important aspects that determine the success rate of the development from bench to market. The aim of this review is to explore how the current knowledge on microbe-microbe and host-microbe interactions can be used to develop high-quality, evidence-based probiotic formulations, specifically probiotic dietary supplements, with a focus on the selection of safe strains with relevant functional properties. In addition, we will highlight aspects of the probiotic manufacturing process that need to be considered during the product development and the subsequent manufacturing process to guarantee consistent efficacy of a probiotic product. For each high-quality probiotic formulation, it is important to screen multiple strains, and select only those strains that show relevant functional properties and that can be considered safe for human consumption. In addition, it is imperative that attention is paid to the product development and manufacturing process, and that safety and quality properties are monitored. Importantly, the beneficial effects of probiotics should be evaluated in product efficacy studies and post-marketing surveys in order to demonstrate their clinical efficacy. All these aspects need to be evaluated and validated during the development of a successful high-quality and ready-to-market probiotic.

Cost-effectiveness analysis of using probiotics, prebiotics, or synbiotics to control Campylobacter in broilers.

Campylobacter is a food safety hazard, which causes a substantial human disease burden. Infected broiler meat is a common source of campylobacteriosis. The use of probiotics, prebiotics, or synbiotics has been associated with controlling Campylobacter infections in broilers, although efficacy remains a contentiously debated issue. On-farm use of probiotics, prebiotics, or synbiotics is gaining momentum. Therefore, it is interesting to analyze the economic viability of this potential intervention to reduce Campylobacter prevalence in broilers. A normative cost-effectiveness analysis was conducted to estimate the cost-effectiveness ratio of using probiotics, prebiotics, or synbiotics in broiler production in Denmark, the Netherlands, Poland, and Spain. The cost-effectiveness ratio was defined as the estimated costs of probiotics, prebiotics, or synbiotics use divided by the estimated public health benefits expressed in euro (€) per avoided disability-adjusted life year (DALY). The model considered differences between the countries in zootechnical and economic farm performance, in import, export, and transit of live broilers, broiler meat and meat products, and in disease burden of Campylobacter-related human illness. Simulation results revealed that the costs per avoided DALY were lowest in Poland and Spain (€4,000-€30,000 per avoided DALY) and highest in the Netherlands and Denmark (€70,000-€340,000 per avoided DALY) at an efficacy ranging from 10 to 20%. In Poland and Spain, using probiotics can be classified as a moderately expensive intervention if efficacy is more than 10%, otherwise it is relatively expensive. In the Netherlands and Denmark, using probiotics is a relatively expensive intervention irrespective of efficacy. However, if probiotics, prebiotics, or synbiotics were assumed to enhance broiler performance, it would become a relatively cost-effective intervention for Campylobacter even at low efficacy levels of 1 to 10%.

Economic evaluation alongside the Probiotics to Prevent Severe Pneumonia and Endotracheal Colonization Trial (E-PROSPECT): study protocol.

INTRODUCTION: Ventilator-associated pneumonia (VAP) is a common healthcare-associated infection in the intensive care unit (ICU). Probiotics are defined as live microorganisms that may confer health benefits when ingested. Prior randomised trials suggest that probiotics may prevent infections such as VAP and Clostridioides difficile-associated diarrhoea (CDAD). PROSPECT (Probiotics to Prevent Severe Pneumonia and Endotracheal Colonization Trial) is a multicentre, double-blinded, randomised controlled trial comparing the efficacy of the probiotic Lactobacillus rhamnosus GG with usual care versus usual care without probiotics in preventing VAP and other clinically important outcomes in critically ill patients admitted to the ICU. METHODS AND ANALYSIS: The objective of E-PROSPECT is to determine the incremental cost-effectiveness of L. rhamnosus GG plus usual care versus usual care without probiotics in critically ill patients. E-PROSPECT will be performed from the public healthcare payer's perspective over a time horizon from ICU admission to hospital discharge.We will determine probabilities of in-ICU and in-hospital events from all patients alongside PROSPECT. We will retrieve unit costs for each resource use item using jurisdiction-specific public databases, supplemented by individual site unit costs if such databases are unavailable. Direct costs will include medications, personnel costs, radiology/laboratory testing, operative/non-operative procedures and per-day hospital 'hoteling' costs not otherwise encompassed. The primary outcome is the incremental cost per VAP prevented between the two treatment groups. Other clinical events such as CDAD, antibiotic-associated diarrhoea and in-hospital mortality will be included as secondary outcomes. We will perform pre-specified subgroup analyses (medical/surgical/trauma; age; frailty status; antibiotic use; prevalent vs no prevalent pneumonia) and probabilistic sensitivity analyses for VAP, then generate confidence intervals using the non-parametric bootstrapping approach. ETHICS AND DISSEMINATION: Study approval for E-PROSPECT was granted by the Hamilton Integrated Research Ethics Board of McMaster University on 29 July 2019. Informed consent was obtained from the patient or substitute decision-maker in PROSPECT. The findings of this study will be published in peer-reviewed journals.

Navigating changes in Clostridioides difficile prevention and treatment.

Clostridioides difficile (C. difficile, previously known as Clostridium difficile) infections are a major health care concern. The Centers for Disease Control and Prevention (CDC) estimates that C. difficile causes almost half a million illnesses in the United States yearly, and approximately 1 in 5 patients with a C. difficile infection (CDI) will experience 1 or more recurrent infections. The incidence of infection has risen dramatically in recent years, and infection severity has increased due to the emergence of hypervirulent strains. There have been noteworthy advances in the development of CDI prevention and treatment, including a growth in the understanding of the role a patient's gut microbiome plays. The 2017 Infectious Diseases Society of America (IDSA) guidelines made a significant change in treatment recommendations for first time CDI episodes by recommending the use of oral vancomycin or fidaxomicin in place of metronidazole as a first-line treatment. The guidelines also included detailed recommendations on the use of fecal microbiota transplant (FMT) in those patients who experience 3 or more recurrent CDI episodes. A number of novel therapies for the treatment of CDI are in various stages of development. Treatments currently in phase 3 trials include the antibiotic ridinilazole, the microbiome products SER-109 and RBX2660, and a vaccine. All of these agents have shown promise in phase 1 and 2 trials. Additionally, several other antibiotic and microbiome candidates are currently in phase 1 or phase 2 trials. A qualitative review and evaluation of the literature on the cost-effectiveness of treatments for CDI in the U.S. setting was conducted, and the summary provided herein. Due to the higher cost of newer agents, cost-effectiveness evaluations will continue to be critical in clinical decision making for CDI. This paper reviews the updated CDI guidelines for prevention and treatment, the role of the microbiome in new and recurrent infections, pipeline medications, and comparative effectiveness research (CER) data on these treatments.

Beneficial microbiota. Probiotics and pharmaceutical products in functional nutrition and medicine.

The article is mainly devoted to such representatives of gut microbiota as lactic acid bacteria and bifidobacteria, with minor accent on less frequently used or new probiotic microorganisms. Positive effects in treatment and prevention of diseases by different microbial groups, their metabolites and mechanisms of action, management and market of probiotic products are considered.

Development of low-cost plant probiotic formulations of functional endophytes for sustainable cultivation of Coleus forskohlii.

Deployment of plant endophytes at field level is reported to make an impact on agricultural crop productivity; development and deployment of suitable crop specific plant probiotics in a suitable delivery matrix is a value-added task. In our study, we attempted to develop bioformulations of native, fungal endophytes of Coleus forskohlii to improve plant yield using two different carrier-based materials (talc and wheat bran). Initially, fungal endophytes (RF1, SF1, and SF2) were grown on sterilized wheat bran under solid state condition and their growth kinetics and pattern were analyzed by ergosterol content and scanning electron microscope, respectively. 10-day-grown fungal endophytic cultures were used for the development of two types of formulations (wheat bran and talc-based formulations) and tested for their efficacy on host plant, C. forskohlii under field conditions. Interestingly, application of wheat bran-based endophytic formulations significantly (p < 0.01) enhanced plant height (12-29%), number of branches (51-63%), root biomass (26-33%), photosynthetic pigments (32-101%), and forskolin content (35-56%) compared to talc-based formulations under field conditions. Shelf life of endophytes (RF1, SF1, and SF2) in both formulations revealed spore viability in wheat bran-based formulations for 6 months storage period as compared to talc-based formulations. Overall, the present investigation envisages developing plant probiotic bioformulations of functional endophytes of C. forskohlii to enhance root biomass and in planta forskolin content.

Saccharomyces cerevisiae and Hanseniaspora osmophila strains as yeast active cultures for potential probiotic applications.

This work allowed the evaluation of the gastrointestinal resistance of five yeasts (Saccharomyces and non-Saccharomyces) in order to assess some biotechnological characteristics linked to the potential probiotics, using a dynamic gastrointestinal simulator (simgi®). The best results obtained were for strains Saccharomyces cerevisiae 3 and Hanseniaspora osmophila 1056. Having optimised the method, the yeasts were subsequently lyophilised, and the one that showed the least loss of viability, S. cerevisiae 3, was used in a freeze-dried form to obtain a new functional food. On the other hand, some characteristics of the product were compared with those of probiotic supplements and other commercial probiotic foods. The obtained functional product showed better parameters than the rest of the samples containing yeasts which, together with the great acceptance shown after the consumer tests, means that it can be presented as a possible commercial functional product.

Food 4 Health - He Oranga Kai: Assessing the efficacy, acceptability and economic implications of Lactobacillus rhamnosus HN001 and ß-glucan to improve glycated haemoglobin, metabolic health, and general well-being in adults with pre-diabetes: study protocol for a 2 × 2 factorial design, parallel group, placebo-controlled randomized controlled trial, with embedded qualitative study and economic analysis.

BACKGROUND: The rates of pre-diabetes and type 2 diabetes mellitus are increasing worldwide, producing significant burdens for individuals, families, and healthcare systems. In New Zealand, type 2 diabetes mellitus and pre-diabetes disproportionally affect Maori, Pacific, and South Asian peoples. This research evaluates the efficacy, acceptability, and economic impact of a probiotic capsule and a prebiotic cereal intervention in adults with pre-diabetes on metabolic and mental health and well-being outcomes. METHODS: Eligible adults (n = 152) aged 18-80 years with pre-diabetes (glycated haemoglobin 41-49 mmol/mol) will be enrolled in a 2 × 2 factorial design, randomised, parallel-group, placebo-controlled trial. Computer-generated block randomization will be performed independently. Interventions are capsulated Lactobacillus rhamnosus HN001 (6 × 109 colony-forming units/day) (A) and cereal containing 4 g ß-glucan (B), placebo capsules (O1), and calorie-matched control cereal (O2). Eligible participants will receive 6 months intervention in the following groups: AB, AO1, BO2, and O1O2. The primary outcome is glycated haemoglobin after 6 months. Follow-up at 9 months will assess the durability of response. Secondary outcomes are glycated haemoglobin after 3 and 9 months, fasting glucose, insulin resistance, blood pressure, body weight, body mass index, and blood lipid levels. General well-being and quality of life will be measured by the Short-Form Health Survey 36 and Depression Anxiety Stress Scale 21 at 6 and 9 months. Outcome assessors will be blind to capsule allocation. An accompanying qualitative study will include 24 face-to-face semistructured interviews with an ethnically balanced sample from the ß-glucan arms at 2 months, participant focus groups at 6 months, and three health professional focus groups. These will explore how interventions are adopted, their acceptability, and elicit factors that may support the uptake of interventions. A simulation model of the pre-diabetic New Zealand population will be used to estimate the likely impact in quality-adjusted life years and health system costs of the interventions if rolled out in New Zealand. DISCUSSION: This study will examine the efficacy of interventions in a population with pre-diabetes. Qualitative components provide rich description of views on the interventions. When combined with the economic analysis, the study will provide insights into how to translate the interventions into practice.

Industry funding effect on positive results of probiotic use in the management of acute diarrhea: a systematized review.

Several investigations have found that industry-funded studies tend to inform results favoring the sponsored products. The pressure to demonstrate that a drug or a product causes a favorable outcome may result in investigation biases from industry-funded research. One example of this could be found in the probiotic research funded by the industry. The aim of this study was to assess the effect of industry funding on positive outcomes of the use of probiotics in the management of acute diarrhea. A systematized review of clinical trials on the use of probiotics in the management of acute diarrhea was performed. The associations between the source of funding, clinical outcomes, probiotic genus, and quality of the study were assessed using the χ-test and Fisher's exact test. Sixty-six clinical trials were included; 27 were industry funded, 18 were nonindustry funded, and 21 did not disclose their funding source. There were 48 positive and 30 negative clinical outcomes. There was no significant association between the source of funding and clinical outcomes (P=0.491). No association between the rest of the studied variables and outcomes was observed either (P>0.05). In clinical trials on the use of probiotics in the management of acute diarrhea, the source of funding has no influence on positive clinical outcomes.

Benefits of probiotics and/or prebiotics for antibiotic-reduced poultry.

Antibiotics have been used for many years as growth promoters. They contribute to build the immunocompetence (i.e. ability of the body to produce a normal immune response following exposure to an antigen) of birds against infectious diseases and as growth promoters. Antibiotics have been widely used as growth promoters in the field of animal production since 1940s. There is a hypothesis that is effect is brought about by dynamic biological interaction with the micro-flora in the intestine. In 1951, the United States Food and Drug Administration approved the use of antibiotics as animal additives to prevent disease in general and, in some cases, to improve efficiency without veterinary prescription. In the 1950s and 1960s, each European state approved its own national regulations about the use of antibiotics in animal feeds. However, using antibiotics may develop bacteria resistant to these drugs. Accordingly, the use of antibiotics has been minimized and replaced by effective dietary supplements such as probiotics and/or prebiotics that are claimed to enhance growth and positively modulate the immune response. The current review paper sheds light on the benefits of using probiotics and/or prebiotics in poultry feed versus the risk of using antibiotics and the mechanisms by which they exert their effects, as well as the economic analysis of using these beneficial additives in poultry feed.

Economic evaluation of S. boulardii CNCM I-745 for prevention of antibioticassociated diarrhoea in hospitalized patients.

Interest in administration of probiotics to prevent antibiotic-associated diarrhoea (AAD) in hospitalized patients is increasing. We determined the cost of antibiotic-associated diarrhoea in hospital settings for non-complicated and Clostridium difficile (C.diff) complicated AAD, and performed a health-economic analysis of AAD prevention with S. boulardii CNCM I-745 (S. boulardii) from data collected in 1 university and 3 regional hospitals in Flanders. Using a decision tree analytic model, costs and effects of S. boulardii for AAD prevention are calculated. Incremental costs due to AAD, including increased length of hospitalization, were calculated using bottom-up and top-down costing approaches from a hospital, healthcare payer (HCP) and societal perspective. Model robustness was tested using sensitivity analyses. Additional costs per hospitalized patient range from € 277.4 (hospital) to € 2,150.3 (societal) for non-complicated and from € 588.8 (hospital) to € 2,239.1 (societal) for C. diff. complicated AAD. Using S. boulardii as AAD prevention results in cost savings between € 50.3 (bottom-up) and € 28.1 (topdown) per patient treated with antibiotics from the HCP perspective; and € 95.2 and € 14.7 per patient from the societal and hospital perspectives. Our analysis shows the potential for using S. boulardii as AAD prophylactic treatment in hospitalized patients. Based on 831,655 hospitalizations with antibiotic administration in 2014 and € 50.3 cost saving per patient on antibiotics, generalized use of S. boulardii could result in total annual savings up to € 41.8 million for the Belgian HCP.

Expanding the reach of probiotics through social enterprises.

The rapid rise in microbiome and probiotic science has led to estimates of product creation and sales exceeding $50 billion within five years. However, many people do not have access to affordable products, and regulatory agencies have stifled progress. The objective of a discussion group at the 2017 meeting of the International Scientific Association for Probiotics and Prebiotics was to identify mechanisms to confer the benefits of probiotics to a larger portion of the world's population. Three initiatives, built around fermented food, were discussed with different methods of targeting populations that face enormous challenges of malnutrition, infectious disease, poverty and violent conflict. As new candidate probiotic strains emerge, and the market diversifies towards more personalised interventions, manufacturing processes will need to evolve. Information dissemination through scientific channels and social media is projected to provide consumers and healthcare providers with rapid access to clinical results, and to identify the nearest location of sites making new and affordable probiotic food and supplements. This rapid translation of science to individual well-being will not only expand the beneficiaries of probiotics, but also fuel new social enterprises and economic business models.

Cost-effectiveness analysis of oral probiotics for the prevention of Clostridium difficile-associated diarrhoea in children and adolescents.

BACKGROUND: The incidence of Clostridium difficile-associated diarrhoea (CDAD) in hospitalized children and adolescents has been increasing year-on-year. Paediatric CDAD places a significant economic burden on healthcare systems. Probiotics are live organisms thought to improve the microbial balance of the host, counteract disturbances in intestinal flora, and reduce the risk of colonization by pathogenic bacteria. AIM: A cost-effectiveness analysis was conducted to assess the economy of probiotics for the prevention of CDAD in children and adolescents receiving antibiotics. METHODS: A decision tree model combining clinical effectiveness, utility and cost data was used. Sensitivity analyses were conducted to determine the robustness of the model outcomes. FINDING: The 'oral probiotics' strategy and 'no probiotics' strategy offered patients 0.05876 and 0.056 quality-adjusted life years (QALYs) at a cost of $16,668.70 and $20,355.28, respectively. The oral probiotics strategy exhibited higher QALY and lower cost, and represents the cost-saving strategy. The results were robust for sensitivity analyses. CONCLUSION: From the perspective of the medical system, oral probiotics as a preventive strategy for CDAD in hospitalized children and adolescents receiving a therapeutic course of antibiotics reduced the risk of CDAD and represents a cost-saving strategy.

Effects of perioperative supplementation with pro-/synbiotics on clinical outcomes in surgical patients: A meta-analysis with trial sequential analysis of randomized controlled trials.

BACKGROUND & AIMS: The Potential benefits and possible risks of perioperative supplementation with probiotics/synbiotics in surgical patients are not fully understood. Recent evidence has rapidly evolved and conveys conflicting results. Thus, we undertook a meta-analysis of randomized controlled trials (RCTs) to valuate the effectiveness, safety, cost-effectiveness and quality of life of perioperative supplementation with pro-/synbiotics. METHODS: We systematically searched PubMed, Embase and the Cochrane Library through October 2015 to identify RCTs that assessed the effects of perioperative supplementation with pro-/synbiotics in surgical patients. The predefined primary efficacy outcome was surgical site infection (SSI). Random-effects model was applied to pool outcome data accounting for clinical heterogeneity. RESULTS: Our meta-analysis included data from 34 trials comprising 2634 participants, of whom 1300 received perioperative pro-/synbiotics intervention and 1334 received valid control treatment. Compared with the control group, patients in the pro-/synbiotics group had a lower risk of SSI (relative risk: 0.65; 95% confidence interval: 0.51, 0.84; P = 0.0007). Trial sequential analysis confirmed the evidence was sufficient and conclusive. Subgroup analyses indicated the findings were consistent in all subgroup analyses except for the probiotics, enteral feeding, pre-/postoperative and live transplantation subgroups. Pro-/synbiotics also reduced the incidence of other infectious complications (including any infection, pneumonia, urinary tract infection, wound infection and sepsis); shortened antibiotic therapy, intensive care unit stay and hospital stay; and promoted earlier first defecation and first bowel movement. Pro-/synbiotics further reduced the incidence of abdominal side effects, lowered hospital costs and improved the Gastro-Intestinal Quality of Life. CONCLUSIONS: For surgical patients, perioperative supplementation with pro-/synbiotics is effective in preventing or controlling SSI and other infectious complications. Perioperative pro-/synbiotics might also be associated with fewer side effects, lower hospital cost and better quality of life. Current evidence indicated that perioperative synbiotics supplementation is preferred and recommended as an adjunct in surgical patients.

Probiotic Supplementation in Preterm: Feeding Intolerance and Hospital Cost.

We hypothesized that giving the probiotic strain Lactobacillus reuteri (L. reuteri) DSM 17938 to preterm, formula-fed infants would prevent an early traumatic intestinal inflammatory insult modulating intestinal cytokine profile and reducing the onset of feeding intolerance. Newborn were randomly allocated during the first 48 h of life to receive either daily probiotic (108 colony forming units (CFUs) of L. reuteri DSM 17938) or placebo for one month. All the newborns underwent to gastric ultrasound for the measurement of gastric emptying time. Fecal samples were collected for the evaluation of fecal cytokines. Clinical data on feeding intolerance and weight gain were collected. The costs of hospital stays were calculated. The results showed that the newborns receiving L. reuteri DSM 17938 had a significant decrease in the number of days needed to reach full enteral feeding (p < 0.01), days of hospital stay (p < 0.01), and days of antibiotic treatment (p < 0.01). Statistically significant differences were observed in pattern of fecal cytokine profiles. The anti-inflammatory cytokine interleukin (IL)-10, was increased in newborns receiving L. reuteri DSM 17938. Pro-inflammatory cytokines: IL-17, IL-8, and tumor necrosis factor (TNF)-alpha levels were increased in newborns given placebo. Differences in the gastric emptying and fasting antral area (FAA) were also observed. Our study demonstrates an effective role for L. reuteri DSM 17938 supplementation in preventing feeding intolerance and improving gut motor and immune function development in bottle-fed stable preterm newborns. Another benefit from the use of probiotics is the reducing cost for the Health Care service.

A Novel Millet-Based Probiotic Fermented Food for the Developing World.

Probiotic yogurt, comprised of a Fiti sachet containing Lactobacillus rhamnosus GR-1 and Streptococcus thermophilus C106, has been used in the developing world, notably Africa, to alleviate malnutrition and disease. In sub-Saharan African countries, fermentation of cereals such as millet, is culturally significant. The aim of this study was to investigate the fermentation capability of millet when one gram of the Fiti sachet consortium was added. An increase of 1.8 and 1.4 log CFU/mL was observed for S. thermophilus C106 and L. rhamnosus GR-1 when grown in 8% millet in water. Single cultures of L. rhamnosus GR-1 showed the highest µmax when grown in the presence of dextrose, galactose and fructose. Single cultures of S. thermophilus C106 showed the highest µmax when grown in the presence of sucrose and lactose. All tested recipes reached viable counts of the probiotic bacteria, with counts greater than 106 colony-forming units (CFU)/mL. Notably, a number of organic acids were quantified, in particular phytic acid, which was shown to decrease when fermentation time increased, thereby improving the bioavailability of specific micronutrients. Millet fermented in milk proved to be the most favorable, according to a sensory evaluation. In conclusion, this study has shown that sachets being provided to African communities to produce fermented milk, can also be used to produce fermented millet. This provides an option for when milk supplies are short, or if communities wish to utilize the nutrient-rich qualities of locally-grown millet.

Probiotics for vaginal health in South Africa: what is on retailers' shelves?

BACKGROUND: Probiotics are widely used to improve gastrointestinal (GI) health, but they may also be useful to prevent or treat gynaecological disorders, including bacterial vaginosis (BV) and candidiasis. BV prevalence is high in South Africa and is associated with increased HIV risk and pregnancy complications. We aimed to assess the availability of probiotics for vaginal health in retail stores (pharmacies, supermarkets and health stores) in two major cities in South Africa. METHODS: A two-stage cluster sampling strategy was used in the Durban and Cape Town metropoles. Instructions for use, microbial composition, dose, storage and manufacturers' details were recorded. RESULTS: A total of 104 unique probiotics were identified in Cape Town and Durban (66.4% manufactured locally). Cape Town had more products than Durban (94 versus 59 probiotics), although 47% were common between cities (49/104). Only four products were explicitly for vaginal health. The remainder were for GI health in adults (51.0%) or infants (17.3%). The predominant species seen overall included Lactobacillus acidophilus (53.5%), L. rhamnosus (37.6%), Bifidobacterium longum ssp. longum (35.6%) and B. animalis ssp. lactis (33.7%). Products for vaginal health contained only common GI probiotic species, with a combination of L. acidophilus/B. longum ssp. longum/B. bifidum, L. rhamnosus/L. reuteri or L. rhamnosus alone, despite L. crispatus, L. gasseri, and L. jensenii being the most common commensals found in the lower female reproductive tract. CONCLUSION: This survey highlights the paucity of vaginal probiotics available in South Africa, where vaginal dysbiosis is common. Most vaginal products contained organisms other than female genital tract commensals.
