Probiotics in food products for children
Vozárová, Petra ; Kvasničková, Eva (referee) ; Španová, Alena (advisor)
Despite of the high level of science and medicine, people are trying to return to the nature and use it for their lives. For example, they are using probiotics, which are live cultures able to reside in the human intestine and there can start their role. The teoretical part of this bachelor thesis deals with probiotic bacteria, their properties and those properties which are important in the food industry and the main part focuses on the probiotics used in baby food. The experimental part of the thesis targets on an analysis of two probiotic supplements for children (BioLac Baby and Probacílium+). There was a DNA isolated from these two products by method of phenol extraction and using magnetic media. The whole DNA isolated from these products was amplificated by genus-specific PCR.

Probiotics and their importance in human nutrition
Formanová, Kristýna ; Vítová, Eva (referee) ; Vránová, Dana (advisor)
A great deal of immune system is located in the colon thanks to a large number of microbs that influence not only digestive tract of a human. The contact of these microbs with the digestive tract of a human is very important for other development of immune defensive mechanisms and the natural immune response, which supports health of a host. That is why in recent years a great deal of attention and efforts have been paid to possibility of human health status improving by a modulation of the intestinal microflora. As probiotics are indicated living microorganisms, that can have positive effects on human health and some species, for example Saccharomyces boulardii, have positive effects in prevention and treatment of many diseases associated with diarrhea. The company Valosun a.s. has provided for testing the probiotic food supplement which is suitable in acute diarrheal disorders. This product has been tried by patients of gastroenterology ambulance. The aim of sociological survey was to map knowledge of respondents in the field of probiotics and probiotic food supplements.

Importance of probiotics in child's nutrition
Augustová, Kamila ; Vítová, Eva (referee) ; Vránová, Dana (advisor)
With great advances in science, medicine and knowledge of a man at the high level of treatment. However, even today the humanity seeking to return to its roots - the nature and use it to maintain its good health. The term probiotics is meant by living organisms that are capable of resettling in the human intestine and have a positive impact on maintaining healthy intestinal microorganisms, which also reflected the positive effects on human health in general.

Special attention is paid to the Fermented Milk Products (further only FMP), their types and processes of manufacture. The practical section surveys the consumption of milk and FMP, paying also attention to the general awareness of FMP among secondary-school students within the Czech Republic. The last section concentrates on the physiology of digestive tract, its structure, and on the benefits that fermented dairy products may have for human health.

The importance of probiotics and prebiotics in diseases of childhood
JERKOVIČOVÁ, Diana
The major goal of this thesis was to explore and summarize the issue of the importance of prebiotics and probiotics in the prevention and treatment of disease in childhood in the form of theoretical work using a variety of literary sources, both Czech and foreign. The most important prerequisite for proper physical growth, health and psychosocial development of the child is good nutrition. The simplest and most natural way of feeding babies is breast-feeding. Breast milk is absolutely perfect composition, optimum temperature and protects infants against various infections and allergies. The colonization of the intestinal microflora, which affects among other things, our immune and digestive system, begins to occur during childbirth (vaginal and fecal microflora from its mother), and from breast milk or the environment. The settlement is delayed if the child was born by Caesarean section. If infants are only breastfed their intestinal microflora is composed of 90% of healthy bifidobacteria and lactobacilli. Probiotics are referred as living organisms (bacteria and yeasts) which have shown positive influence on the health of the host when administered in adequate amounts. Probiotics in pediatric practice has tripled over the last ten years. The most used are bifidobacteria and lactobacilli. Prebiotics are non-digestible food ingredients that beneficially affect the host by selectively stimulating the growth and / or activity of certain strains of intestinal microflora. The first area of concern of the effect of prebiotics and probiotics in the prevention and treatment of various diseases in children were atopic disease whose prevalence in recent decades, greatly affects the whole society. In case of atopic dermatitis and food allergies there are number of optimistic studies that demonstrate the positive effect of combination of probiotics and prebiotics (synbiotics), on the other hand, there are studies on this issue which are rather skeptical and do not confirm this positive effect. Convincing results come from the area of diarrhoea. Regarding acute diarrhoea that are in children caused mainly by rotavirus, was observed clearly positive effects of probiotics, which occur to shorten the duration of rotavirus diarrhea to about 40 hours, or to reduce the number of stools and the duration of diarrhea by approximately one day, and especially where there has been the early administration. Similarly, in a majority of cases the positive impact of the use of probiotics for diarrhoea associated with antibiotic treatment, especially during simultaneous use. Regarding inflammatory bowel diseases, favorable results are achieved in particular in the case of ulcerative colitis, which is the use of a positive effect of probiotics in the treatment of patients with mild to moderate inflammatory activity comparable to drug treatment, but in Crohn's disease, a positive influence is entirely clear. Positive results also come in necrotizing enterocolitis in preterm neonates. However, these results are difficult to interpret because studies. Very similar results in the effects of probiotics and prebiotics are in the prevention of nosocomial sepsis in preterm infants. Although showing some positive effects, particularly in infants with very low birth weight, there was a positive effect of probiotics or prebiotics in different studies fully demonstrated and it would be desirable to assess the safety and effectiveness of future research. It would be necessary to examine which specific types of probiotics should be used and in what dosage. In general, therefore, could be said that despite all the optimistic results of a positive effect of probiotics and prebiotics in the prevention and treatment of various diseases, there is the need for further research, that this positive effect is confirmed or refuted.

Probiotic bacteria and their health importance.
ČAPKOVÁ, Martina
Nowadays probiotics and their positive effect on human health is often discussed topic. Their positive effects on the immune system and intestinal flora are proven scientifically. In recent years, potential effects of probiotics in prevention and treatment of diseases have been the centre of interest. Despite this fact public doesn´t have enough information about effects of probiotic bacteria. The theoretical part deals with a conception of probiotics, prebiotics and synbiotics, their features, effects and applications in food and health benefits. The practical part mentions results of public awareness of probiotics. 240 people, devided into 4 groups, took part in this questionnaire survey.
