Probiotics are live microorganisms, which when ingested in sufficient amounts, confer health benefits to the host by improving the gut microflora balance. The purpose of this research was to determine whether commercial probiotic products containing multitude of commensal bacteria would reduce the growth rate of pathogenic bacteria, specifically Escherichia coli and Salmonella typhimurium. Growth curves were established, and the growth rates were compared for samples of E. coli, S. typhimurium, Nature’s Bounty Controlled Delivery probiotic, Sundown Naturals Probiotic Balance probiotic, and cocultures of the pathogenic bacteria mixed with the probiotics. The findings of this research were that the commercial probiotics significantly reduced the growth rate of E. coli and S. typhimurium when combined in cocultures. Probiotics containing multiple strains may be taken prophylactically to reduce the risk of bacterial infections caused by E. coli and S. typhimurium. Probiotics could be used to reduce the high global morbidity and mortality rates of diarrheal disease.

Nosema ceranae is a microsporidian fungus that parasitizes the midgut epithelial cells of honey bees, Apis mellifera. Due to the role that midgut microorganisms play in bee health and immunity, food supplementation with prebiotics and probiotics may assist in the control of N. ceranae. The dietary fiber prebiotics acacia gum, inulin, and fructooligosaccharides, as well as the commercial probiotics Vetafarm Probotic, Protexin Concentrate single-strain (Enterococcus faecium), and Protexin Concentrate multi-strain (Lactobacillus acidophilus, L. plantarum, L. rhamnosus, L. delbrueckii, Bifidobacterium bifidum, Streptococcus salivarius, and E. faecium) were tested for their effect on N. ceranae spore loads and honey bee survivorship. Bees kept in cages were inoculated with N. ceranae spores and single-dose treatments were administered in sugar syrup. Acacia gum caused the greatest reduction in N. ceranae spore numbers (67%) but also significantly increased bee mortality (62.2%). However, Protexin Concentrate single-strain gave similarly reduced spore numbers (59%) without affecting the mortality. In a second experiment, multiple doses of the probiotics revealed significantly reduced spore numbers with 2.50 mg/mL Vetafarm Probotic, and 0.25, 1.25, and 2.50 mg/mL Protexin Concentrate single-strain. Mortality was also significantly reduced with 1.25 mg/mL Protexin Concentrate single-strain. N. ceranae-inoculated bees fed 3.75 mg/mL Vetafarm Probotic had higher survival than N. ceranae-inoculated bees, which was similar to that of non-inoculated bees, while N. ceranae-inoculated bees fed 2.50 mg/mL Protexin Concentrate single-strain, had significantly higher survival than both N. ceranae-inoculated and non-inoculated bees. Protexin Concentrate single-strain is promising as it can reduce N. ceranae proliferation and increase bee survivorship of infected bees, even compared to healthy, non-infected bees.

Modulation of the gut microbiota through the use of probiotics has been widely used to treat or prevent several intestinal diseases. However, inconsistent results have compromised the efficacy of this approach, especially in severe conditions such as inflammatory bowel disease (IBD). The purpose of our study was to develop a personalized probiotic strategy and assess its efficacy in a murine model of intestinal inflammation. Commensal bacterial strains were isolated from the feces of healthy mice and then administered back to the host as a personalized treatment in dextran sodium sulfate (DSS)-induced colitis. Colonic tissues were collected for histological analysis and to investigate inflammatory markers such as Il-1β, Il-6, TGF-β, and Il-10, and the enzyme myeloperoxidase as a neutrophil marker. The group that received the personalized probiotic showed reduced susceptibility to DSS-colitis as compared to a commercial probiotic. This protection was characterized by a lower disease activity index and reduced histopathological damage in the colon. Moreover, the personalized probiotic was more effective in modulating the host immune response, leading to decreased Il-1β and Il-6 and increased TGF-β and Il-10 expression. In conclusion, our study suggests that personalized probiotics may possess an advantage over commercial probiotics in treating dysbiotic-related conditions, possibly because they are derived directly from the host’s own microbiota.

Global warming affected increasing the risk of ducks to be more succeptable to heat stress which leads to decrease welfare and production. This research aimed to study duck welfare and productivity under probiotic and antioxidants administration at commercial farms. The method used was experiment with Completely Randomized Designed (CRD) based on factorial pattern. The treatment was dose of natural/homemade and commercial probiotics combined with vitamin C at 400 mg kg–1 and 600 mg kg–1 feed. Thus there were four treatment combinations. Each treatment was replicated five times, totally were 20 flocks of duck. Each flock had 50 laying females so there were 1 000 ducks. The treatment was conduced for 2 mo. The parameters observed included, i) duck welfare based on Heterophyl/Lymphocyte (H/L) ratio; ii) egg production consisted of (a) duck day production, and (b) egg weight. This study concluded that administration of combination between homemade probiotic and vitamin C at 600 mg kg–1 feed significantly (p < 0.05) increased duck welfare and egg production but did not affect egg weight.

The aim of our study was to evaluate the contents and labelling of five commercial probiotics marketed for veterinary administration. The information on the product was obtained from the inserted leaflet or the data on the package. Quantitative bacteriological culture was performed in all products, and isolates were identified via biochemical characteristics. Comparison of actual contents versus label claims was performed. Four products correctly provided information on expiry dates, species and quantity of bacteria per gram or kilogram of product. In one product, there was no probiotic species mentioned in the Czech text on the package. Culture examinations of all the three products containing Enterococcus faecium resulted in finding the declared quantity of bacteria. They also contained Lactobacillus sp. not mentioned in the leaflet. Culturing the mixture of Bacillus subtilis and Lactobacillus paracasei, we found only Bacillus subtilis in a quantity by one order lower than declared. In an incorrectly labelled product, Lactobacillus sp. was found instead of yeast species. Most commercial veterinary probiotic preparations are not accurately represented by label claims.

The Impact

The study was carried out to explore the impact of probiotics on shrimp (Penaeus monodon) in the Shrimp Research Station ponds during the culture period of 90 days. The experiment was set in 9 on-station ponds having an area of 0.052?0.064 ha. Three treatments of the experiment were: super Ps probiotics broadcast all over the ponds mixed with clay (T1), probiotics broadca Zymetin st over the pond mixed with feed (T2) and control (without probiotics) the ponds (T3) and each treatments having 3 replicates. All Juvenile of shrimp were stocked at a density of 6.0 juv/m2 and was fed with quality feed (gold plus-grower) twice daily at the rate of 10.3% of shrimp biomass. Water quality parameters namely temperature, water depth, dissolved oxygen, pH, salinity, ammonia, nitrate, total alkalinity and transparency were within suitable range for shrimp growth without finding any stress. Growth of shrimp was measured and feed was adjusted after every fortnight. The average weight of shrimp in T1, T2 and T3 was 22.065 ±5.52, 19.87 ±4.98 and 11.01 ±0.86g, respectively. Higher growth was obtained from T1 followed by T2 and T3. Day after 90 of husbandry, all shrimp were harvested. The survivality rate of shrimp production was reckoned 80%. The production of shrimp was found 760 kg/ha in T1, 665 kg/ha in T2 and 205.19 kg/ha. in T3. So the highest production was found using super PS (T1). Food conversion ratio (FCR) of prawn was found higher (2.48) in T3 compared to T1 (1.83) and T2 (2.01). The result of the study is therefore revealed that probiotics paly a most important role in growth, survival and production of shrimp by maintaining good water quality environment throughout the culture period. It may be therefore concluded that probiotics can be utilized well the shrimp ponds to get higher growth and production keeping the congenial environment.Asian J. Med. Biol. Res.

Recent evidence suggests that probiotics, prebiotics and synbiotics may serve as important dietary components in the prevention (especially) and treatment of cardiovascular diseases (CVD), but the recommendations for their use are often based on brief reports and small clinical studies. This review evaluates the current literature on the correlation between CVD and probiotics, prebiotics and synbiotics. Although research on probiotics, prebiotics and synbiotics has grown exponentially in recent years, particularly regarding the effect of probiotics on CVD, their mechanisms have not been clearly defined. It has been proposed that probiotics lower cholesterol levels, and may protect against CVD, by increasing bile salt synthesis and bile acid deconjugation. Similar effects have also been observed for prebiotics and synbiotics; however, probiotics also appear to have anti-oxidative, anti-platelet and anti-inflammatory properties. Importantly, probiotics not only have demonstrated effects in vitro and in animal models, but also in humans, where supplementation with probiotics decreases the risk factors of CVD. In addition, the properties of commercial probiotics, prebiotics and synbiotics remain undetermined, and further experimental research is needed before these substances can be used in the prevention and treatment of CVD. In particular, well-designed clinical trials are required to determine the influence of probiotics on trimethylamine-N-oxide (TMAO), which is believed to be a marker of CVDs, and to clarify the long-term effects, and action, of probiotic, prebiotic and synbiotic supplementation in combination with drug therapy (for example, aspirin). However, while it cannot be unequivocally stated whether such supplementation yields benefits in the prevention and treatment of CVDs, it is important to note that clinical studies performed to date have not identified any side-effects to use.

ABSTRACT The aim of the study was to assess the safety of three newly developed synbiotic preparations in feeding chickens. The study was carried out on 84 Specific Pathogen Free chickens, between 1st and 21st day of their life. Animals were divided into four groups fed ad libitum: three with an addition of synbiotics A, B or C and a control group (feed with no additives). Synbiotics contained Lactobacillus, Saccharomyces cerevisiae and inulin (prebiotic). Rearing parameters were determined taking into account undesirable clinical and sectional symptoms, daily mortality and body weight of birds. In addition, chicken blood parameters were determined based on haematological, biochemical and serological tests. Samples of the intestinal content and of the excreta constituted a material for research aimed at determination of the dominant chicken gut microbiota. On the basis of the conducted investigation, it was found that synbiotics met the basic requirements for this type of formulas regarding the safety of use and had a positive effect on the health of chickens. Therefore, further research is being carried out on the application of these formulas in large-scale production. The next step of the research will be the comparison of effects of synbiotics with commercial probiotics.
