Oil of oregano helps inhibit (and sometimes kill) ninety (90) different types of detrimental bacteria, fungi, parasites, protozoa, yeasts, and molds, such as:
- Aspergillus (flavus and parasiticus)
- Bacillus cereus
- Blastocystis hominis
- Candida albicans
- Cryptococcus neoformans (an opportunistic fungus affecting the AIDS patients)
- Endolimax nana
- E. Coli (Escherichia coli)
- Entamoeba hartmanni
- Giardia lamblia (the cause of Giardiasis)
- Klebsiella pneumoniae
- Listeria monocytogenes (commonly called Listeria)
- Mycobacterium paratuberculosis
- Proteus (mirabilis, vulgaris)
- Pseudomonas aeruginosa*
- Salmonella enterica (Gram-negative bacterium)
- Staphylococcus aureus (responsible for "Golden Staph")
- Streptococcus pneumoniae ("Strep").
* PLEASE NOTE: Pseudomonas aeruginosa is a common bacterium found in soil, water, skin flora and most man-made environments. An opportunistic pathogen of immunocompromised individuals vulnerable to infections, it typically infects the pulmonary tract, urinary tract, burns, wounds, and also causes other blood infections.
P. aeruginosa is the third leading cause of hospital-acquired urinary tract infections, accounting for approximately 12 percent of all infections of this type. They are usually related to urinary tract catheterization, instrumentation or surgery.
It is a common cause of post-operative infection in radial keratotomy (RK) eye surgery patients and of "hot-tub rash" (dermatitis), caused by lack of proper periodic attention to water quality.
P. aeruginosa appears to be among the most adherent of common urinary pathogens to the bladder uroepithelium. An infection can occur via an ascending or descending route.
P. aeruginosa can also invade the bloodstream from the urinary tract. This route is the source of approximately 40 percent of P. aeruginosa infections.
P. aeruginosa can cause chronic opportunistic infections. These kinds of infections are a serious problem for medical care. Many patients, immunocompromised and the elderly in particular, often cannot be treated effectively with traditional antibiotic therapy.
As a highly relevant opportunistic pathogen, P. aeruginosa has low antibiotic susceptibility. It is naturally resistant to a large range of antibiotics and may demonstrate additional resistance after unsuccessful treatment.
