PROBIOTICS
AND
PREBIOTICS –
What are they
all about..?
Background
• Probiotics are dietary supplements
•
•
containing potentially beneficial bacteria
or yeast, with lactic acid bacteria { LAB }
LAB have been used in the food industry
for many years, because they are able to
convert sugars and other carbohydrates
into lactic acid.
This provides characteristic sour taste of
fermented dairy foods such as yogurt, and
acts as a preservative, by lowering the pH.
And…
• Prebiotics are a category of
functional food, defined as : Non
digestable food ingredients that
beneficially affect the host by
selectively stimulating the growth
and / or activity of one or a limited
number of bacteria in the colon, and
thus improve the host health. Eg;
oligosaccharides
The Theory
• The body contains a miniature ecology
of microbes, collectively known as gut
flora.
• The number of bacterial types can be
thrown out of balance by a wide range of
circumstances including the use of
antibiotics or other drugs, excess alcohol,
stress, disease, exposure to toxic
substances , or even the use of
antibacterial soap.
Really…?
• Do they survive in the acidic stomach
environment, the alkaline conditions in the
duodenum, as well as their ability to
adhere to the intestinal mucosa of the
colon and to colonize the colon. Some
probiotics such as Lactobacillus GG and
Lactobacillus plantarum, do. After
passage through the stomach and the
small intestine, they become established
transiently in the colon.
Also…
• Lactobacillus casei has been
demonstrated to increase levels of
circulating Ig A in infants infected with
rota virus.
• Lactobacillus acidophilus and
Bifidobacterium bifidum appear to
enhance the nonspecific immune
phagocytic activity of circulating blood
granulocytes.
So…
• I suggest when giving antibiotics to all
•
•
age groups apart from pregnant and
breast feeding
Anecdotal evidence so far: less D&V
,lower incidence of vaginal thrush,
controlled diverticulosis.
Potential s/e theoretically include
flattulence/ constipation/ Lactobacillus
bacteremia and endocarditis.
And…
….has been found to secrete a protease which
digests two protein exotoxins, toxin A and toxin
B , which appear to mediate diarrhoea and
collitis caused by Clostridium difficle
• Lactobacillus rhamnosus GG and
bacterium
lactis Bb 12 produce significant improvement
of atopic eczema in children: the decrease in
the signs and symptoms occurred in parallel with
a reduction in the concentration of circulating
CD4+ T lymphocytes and an increase in TGF –
beta 1, indicating suppressive effects on T cell
functions in this disorder.
The players
• Bifidobacterium
• Lactobacillus
• Lactococcus
• Saccharomyces
• Streptococcus
• Thermophilus
• Enterococcus
How do they work…?
• Probiotics may have antibacterial,
immunomodulatory,anticarcinogenic,
antidiarrhoeal, antiallergenic and
antioxidant activities.
• The antibacterial activity may partially
be due to the ability to colonise the
colon and reinforce the barrier
function of the intestinal mucosa.
