3. INTRODUCTION PROBIOTICS are live bacteria and yeast that are good for and have beneficial effects on the host by improving its intestinal Microbial balance. The term Probiotic comes from the Latin or Greek Pro , “before , forward ”, and bios , or “life” _ thus Probiotics are life _ promoting. In this case , we use the term Probiotics to refer to beneficial bacteria.

4. HISTORY Probiotics term coined in 1965 by Lily And Stillwell Probiotics , which means “for life” was meant to contrast “antibiotics”, popularly prescribed and known to also of destroy beneficial organism and impact the immune system.

5. WHAT ARE PROBIOTICS? Probiotics : Probiotics defined as microorganisms that have a beneficial effect on the host Intestinal Microbial balance. Probiotic organisms are live microorganisms thought to be beneficial to the host organism. According to the currently adopted definition by FAO/ WHO, Probiotics are:“live microorganisms which when administered in adequate amount confer a health benefit on the host”.

6. WHY ARE PROBIOTICS IMPORTANT FOR HUMAN HEALTH

7. Who NEEDS PROBIOTICS? People with weak immune systems,frequent respiratory infections and congestion. People with food or respiratory allergies. People suffering from inflammatory bowel disorders, Constipation or Intestinal infections.

8. Mode of action of PROBIOTICS Production of inhibitory compounds Competition for chemicals/available energy Enhancement of the immune response Improvement of the water quality A source of macro and micro _ nutrients Enzymatic contribution to digestion

9. CHARACTERISTICS OF PROBIOTICS Able to survive the passage through the digestive system Able to maintain good viability Able to utilize the nutrients and substrates in a normal diet Non _ pathogenic and non _ toxic Capable of exerting a beneficial effect on the host

10. Identification Of strains Of PROBIOTICS Effects of probiotics are strain specific Strain identify is important to link a strain to a specific health effect as well as to a enable accurate surveillance and epidemiological studies Both phenotypic and genotypic tests should be done using validated standard methodology.

11. PROBIOTICS in foods Some fermented Products containing similar Lactic acid bacteria include: Pickled Vegetables Soy sauce Kefir Fermented bean paste such as tempeh, Miso and doenjang

12. Dairy products Curd Yogurt Cheese Kefir Sour Cream

13. PROBIOTICS are used in several clinical Conditions Probiotics were identified to beneficially affect the host by improving its intestinal Microbial , inhibiting pathogens and toxin producing bacteria. Today specific , health effects are being investigated and documented including alleviation of chronic Intestinal inflammatory diseases , prevention and treatment of pathogen _ induced diarrhoea , urogenital infections , and atopic diseases.

14. Advantages of PROBIOTICS Antibiotic associated diarrhea Probiotics and cancer Hepatic diseases Helicopter pylori infections Treat high cholesterol Use of probiotics beyond GIT (Allergy)

15. DISADVANTAGES of PROBIOTICS Taking them larger amounts might produce digestive issues , such as gas and bloating , but the are usually temporary. Treating lactobacillus septicemia which is a potentially disease caused by the consumption of probiotics. Discomfort in the gastrointestinal tract Allergy

16. Conclusion Due to the many benefits or probiotics in the absence of any risk , they have become a useful tool for the medical community. They not only boost the functioning of the immune system , the naturally aid in fighting bad bacteria by supplying the body with enough good to keep the body in symbiosis.
