Good Bacteria for the Human body (lab)

Cards (21)

  • Good” bacteria, also known as beneficial bacteria to the body and enhance health. ◼ 85% good bacteria and 15% bad bacteria. ◼ Scientists estimate that only 1-10% of total bacteria have even been discovered. ◼ Around 100 trillion good bacteria live in and on our bodies- these bacteria reside in our gut
  • Friendly Intestinal Bacteria are called Probiotics ◼ They help break down toxins and help build immunity ◼ Mutualism
  • Probiotic ◼ Probiotic was coined by Lily And Stillwell in 1965 ◼ According to WHO, “probiotics are live microorganisms when administered adequate amounts confer a benefit on a host
  • Probiotics Treatment : ◼ Diarrhea ◼ Irritable bowel syndrome ◼ Ulcerative colitis and Crohn’s disease ◼ Tooth decay, gingivitis and periodontitis ◼ Eczema Prevention: Probiotics can help with diarrhea by restoring the balance of bacteria in your gut
  • Elie Metchnikoff - who has worked at the famous Pasteur Institute in Paris during 28 years, was the first to suggest that Lactic Acid Bacteria were beneficial to the intestinal
  • Lactobacillus(Lactic acid bacteria) ◼ This species of bacteria produces lactase, the enzyme that breaks down lactose, or milk sugar. These bacteria also produce lactic acid. Lactic acid helps control the population of bad bacteria. ◼ Lactobacillus bacteria are found naturally in the: ◼ mouth ◼ small intestine ◼ vagina 
  • Japanese microbiologist,
    Minoru Shirota - who developed a new strain of bacteria called Lactobacillus casei Shirota. 
  • Lactobacillus (group) ◼ Breaks down food, absorbs nutrients, make vitamins, helps prevents bad bacteria
    Lactobacillus can inhibit the growth of cancer cells in the colon and mammary glands by preventing the body from being contaminated with pathogenic flora.
  • Bifidobacteria ◼ Another Probiotic – same benefits as Lactobacillus ◼ Bifidobacteria are a group of bacteria that normally live in the intestines. ◼ Bifidobacteria were first isolated from the feces of breast-fed infants in 1899, by Henri Tissier, and were designated Bacillus bifidus
  • Probiotics are live microorganisms that provide a specific health benefit when consumed. Uses of Bifidobacteria: ◼ digest dietary fiber, support the immune system,help prevent infection, for preventing the common cold or flu, and produce vitamins and other important chemicals, including B vitamins and healthy fatty acids 
  • Side effects ◼ When taken by mouth: Bifidobacteria are LIKELY SAFE for healthy adults when taken by mouth appropriately. In some people, treatment with bifidobacteria might upset the stomach and intestine, causing diarrhea, bloating and gas
  • Staphlococcus hominis ◼ Just 1 of the 180 species of friendly skin bacteria ◼ It helps prevent bad Staph from attaching to your skin cells ◼ It occurs very commonly as a harmless commensal on human and animal skin and is known for producing thioalcohol compounds that contribute to body odor.
  • Thiols used as odorants to assist in the detection of natural gas (which in pure form is odorless), and the "smell of natural gas" is due to the smell of the thiol used as the odorant. ◼ Thiols are sometimes referred to as mercaptans 
  • Staphlococous hominis may occasionally cause infection in patients whose immune systems are compromised, for example by chemotherapy or predisposing illness. 
  • Streptococcus thermophilus benefits: ◼ Improves digestion ◼ Reduces diarrhea after consumption of the antibiotics ◼ Decreases the symptoms of ulcerative colitis ◼ Reduces leaking bowel symptoms ◼ Breaks down lactose
  • Streptococcus thermophilus ◼ Streptococcus thermophilus-bacteria produce the enzyme lactase ◼ This probiotic strain is located mainly in the colon and has a strong effect on the gastrointestinal tract, immune system and many other health-improving factors. 
  • Streptococcus thermophilus benefits:
    Reduces the symptoms of IBS ◼ Reduces acute diarrheaBoosts immunity ◼ Prevents and fights upper respiratory tract infections (eg pneumonia) ◼ Prevents ulcers caused by Helicobacter pylori ◼ Reduces the symptoms of AIDS
    Some people, such as those with compromised immune systems, short bowel syndrome, central venous catheters, heart valve disease and premature infants, may be at higher risk for adverse events.
  • Saccharomyces boulardii ◼ Saccharomyces boulardii is a type of yeast, but it acts as a probiotic, commonly known as brewer's yeast and baker's yeast ◼ helpful for preventing and treating traveler’s diarrhea, including infectious types such as rotaviral diarrhea in children diarrhea caused by gastrointestinal (GI) take-over (overgrowth) by “bad” bacteria in adults and diarrhea associated with tube feedings ◼ useful for treating acne, and reducing the side effects of antibiotic treatment for H. pylori bacteria.
  • In Nature:
    Cyanobacteria or ‘blue-green algae’ produce oxygen and nutrients other organisms need to live. ◼ Cyanobacteria get their name from the bluish pigment phycocyanin, which they use to capture light for photosynthesis.  
  • Rhizobia Bacteria ◼ Converts Nitrogen into forms that Plants can use to make Proteins which is required for many crops to grow
  • Rhizobia bacteria are found in the soil, where they survive until legume plant roots are available to infect. ◼ The first known species of rhizobia, Rhizobium leguminosarum, was identified in 1889, and all further species were in it
