Not all types of bacteria are bad. In fact, certain bacteria actually posses many health benefits and are referred to as “good bacteria”. They are responsible for a number of functions including maintaining a healthy gut, absorb nutrients, digest food, and preventing the spread of diseases, so the importance of good bacteria cannot be overstated. Good bacteria living inside the body are known as ‘probiotics’.
Probiotics reside in different parts of our body including the Mouth, Vagina, Urinary tract, Skin, and Lungs. These good bacteria help function as defense against unhealthy or bad bacteria.

  5. Blocking the entry of bad bacteria in the blood stream by supporting the cells that line our gut
  6. Breaking down and absorbing medications
  7. Treating various different skin conditions including eczema, acne, rashes, rosacea, and psoriasis
  8. Treating Ulcerative Colitis and Crohn’s disease
  9. Treating Irritable Bowel Syndrome

Common types of Probiotic Bacteria:

Lactobacillus:

Lactobacillus is one of the good bacteria found in our body. These bacteria reside in our digestive, urinary, and genital systems. Lactobacillus is found in some fermented foods like yogurt. They are also are found in certain dietary supplements. Lactobacillus contains many different species.
Lactobacillus acidophilus: This is one of the most commonly used probiotics and is found in fermented soy products such as miso and tempeh as well as yogurt. The probiotic is used to treat bacterial infections of the vagina, as well as to prevent and treat diarrhea.
Lactobacillus rhamnosus GG: This can help in treating traveler’s diarrhea, diarrhea caused by Clostridium difficile (C. difficile) bacteria, or the one that may be caused by antibiotics in children. Lactobacillus rhamnousus GG is also used to help prevent eczema in infants.
Lactobacillus salivarius: This one helps block the growth of the bacteria that cause peptic ulcers known as Helicobacter pylori (H. pylori).
Lactobacillus plantarum: This type of bacteria improves the immune system and hence prevents the invasion of disease-causing bacteria in the body.

In addition, lactobacillus has many other uses. Some of these include the prevention of colic in babies, lung infections in young children, diarrhea caused by antibiotics and infection, diarrhea in adults admitted in the hospital or receiving chemotherapy treatment for cancer. Moreover, it is also used to treat bowel conditions like ulcerative colitis and Irritable Bowel Syndrome (IBS). Further illustrating the importance of good bacteria

Bifidobacteria

Bifidobacteria are also good bacteria with many health benefits to human beings. They live in the gastrointestinal tract, vagina and mouth of humans.
Bifidobacteria consists of about 30 different variants including the following:
Bifidobacteria bifidum: This branch of probiotics can help protect against bad bacteria and relieve IBS symptoms.
Bifidobacteria infantis: Are believed to help ease the symptoms of IBS, such as abdominal pain, gas, as well as bloating
Bifidobacteria lactis: Improve cholesterol levels in women and in people with type 2 diabetes
Moreover, bifidobacteria is believed to help treat constipation as well as prevent airway infections.

Streptococcus thermophilus

These bacteria help in the production of the enzyme ‘lactase’. Lactase is required by the body in order to digest the sugar in milk as well as other dairy products. Researchers also believed that Streptococcus thermophilus can help in the prevention of lactose intolerance.
