Staph infections: Antibiotics as treatment

Staphylococcus aureus infections are typically triggered by common bacteria that are often present in the nose or on the skin. Among healthy individuals, the staph bacteria do not cause infection. It is important to note that the staph bacteria are one of the main causes of skin infections all over the world and antibiotics are not usually required. On the other hand, once the immune system of an individual is weak or there is an open wound, the bacteria are capable of triggering serious infections that can be problematic. The treatment for these cases of staph infections involves the use of antibiotics.


At one point in time, penicillin can be used to manage the usual cases of staph infections. It is sad to note that the abuse of antibiotics (not completing the prescribed therapy period or using them when not needed) resulted to the increased resistance of staph to penicillin, thus making the antibiotic ineffective. Even though it is still effective in some cases of staph infections, only about 10% of cases respond to penicillin.


Staph infection

Once the immune system of an individual is weak or there is an open wound, the bacteria are capable of triggering serious infections that can be problematic.

Methicillin is often the next choice after penicillin. Nevertheless, the staph bacteria are developing immunity to methicillin as well and it is called as methicillin-resistant staphylococcus aureus (MRSA).

This antibiotic is effective in managing less than 50% of staph infections. Always bear in mind that MRSA is considered serious since there are limited treatment options for staph that is resistant to methicillin.


A potent but toxic antibiotic used in managing staph infections that are resistant to other antibiotics is vancomycin. Even though it is still effective in treating most cases, there are some strains of the bacteria that developed resistance to vancomycin as well.

The best way to determine which antibiotic is effective against staph infection is to test the bacteria against various antibiotics available in the laboratory.


Mupirocin is an antibiotic ointment that is given for staph bacteria present within the nasal cavity. In a study conducted, mupirocin can drastically reduce the level of staph bacteria in the nasal cavity.

Tea tree oil

If you have heard about tea tree oil, it is extracted from the leaves of the tea tree that possesses antibiotic properties. Tea tree oil is considered as a natural substance that is effective against MRSA.

In a study conducted, it revealed that all the strains of staph bacteria that were tested were not resistant to tea tree oil. These included strains that were resistant to methicillin and mupirocin. Tea tree oil is available over-the-counter in most health food stores.

Depending on the findings of the doctor, the suitable antibiotic will be given to properly manage the staph infection. It is vital to follow the prescribed treatment period in order to ensure that the infection is under control.
