*Penicillins - Amoxicillin, Ampicillin, Flucloxacillin and other drugs
with the ending “-cillin”. Damage Lactobacilli and
Bifidobacteria, while promoting the growth of the Proteus
family, Streptococci and Staphylococci. This group of
Antibiotics allows bacteria normally found in the bowel to move up the intestine,
causing IBS and other digestive disorders

*Tetracyclines - Tetracycline, Doxycycline and other “-cyclines”. Routinely
prescribed for Acne from 3 months to 2 years. This group can alter
protein structure in the mucous membranes
of the intestinal wall. This makes the gut wall
vulnerable to invasion and alerts the immune
system to attack these changed proteins,
starting an auto-immune reaction.
Tetracyclines also stimulate growth of the
Candida fungus, Staphylococci and Clostridia in the digestive tract.

*Aminoglycosides - Gentamycin, Erythromycin, other “-mycins”. These drugs
effect the population of E. Coli and Enterococci.

*Antifungal Antibiotics - Nystatin, Amphotericin. Stimulate the growth of the
Proteus family and lactose-negative E. Coli species.


• A healthy adult has 3 to 5 pounds of bacteria in the gut alone
• Three major groups
• Essential/beneficial
• Bifidobacteria, Proprionobacteria, physiological strains of E. coli,
Peptostreptococcus, and Enterococci
• Opportunistic
• Bacterioids, Peptococci, Staphylococci, Streptococci
• About 500 various species known to science


• People with damaged flora often have an overgrowth of iron loving bacteria
(actinomycetes, mycobacterium, cornybacterium, etc...)

• Bifidobacterium secrete a substance called muramyl
dipeptide, which activates lymphocytes•as a result, a healthy gut wall is packed full of
lymphocytes. lymphocytes produce immunoglobulins IgA
IgA destroys the membranes of bacteria, viruses, fungi and parasites
In the presence of healthy gut flora there is an increased presence of IgA
