Methicillin-resistant
Staphylococcus Aureus
by Torie Stratton, Jordan Scott, and Megan Pazzelli
Type of Disease
Methicillin-resistant Staphylococcus Aureus is
a bacterial infection caused by staph bacteria
that has become resistant to most antibiotics
normally used to treat ordinary
staph infections. Another name
for this disease is MRSA.
Where MRSA Originated
MRSA originated from the Staph bacteria, and
came about due to the overuse of medicines.
The Staph
bacteria
became
resistant to
penicillin
and other
treatments,
resulting in
MRSA.
History of MRSA
The Staph bacterium was discovered
in the 1880s. In the 1940s, treatments
for Staph, such as penicillin, were
discovered. From that point on, the use
of those treatments (and overuse)
caused the bacterium’s resistance,
resulting in MRSA. The first human
cases of MRSA were in 1968.
Symptoms of MRSA
•
Cellulitis- infection of the skin and tissues immediately beneath the skin,
usually starting as small red bumps in the skin with some areas
resembling a bruise
•
Boils- pus-filled infections of hair follicles
•
Abscesses- collections of pus in or under the skin
•
Sty- an infection of an oil gland in the eyelid
Transmission of MRSA
MRSA, like all staph bacteria, can be spread through contaminated
objects or casual contact. It is normally passed from the hands of
someone who has MRSA. It is not
usually spread through the air. In
healthcare-associated MRSA, it is
normally passed to a person who is
already sick or has a weakened
immune system.
Cures or Treatments for MRSA
MRSA is considered to be treatable even though it is
resistant to a lot of antibiotics. Bactrim and vancomycin
are the drugs normally used to fight MRSA. But due to
MRSA’s resistant nature, there is emerging antibiotic
resistance being noticed. But antibiotics
are not always necessary. If
the only symptom is a skin
boil, doctors can normally
just make an incision and
drain it.
