The Diagnosis process
In order to establish if a patient is infected culture of the bacteria from an infected area must be taken and analyzed. An infected area represents any skin area with blisters, pus or abscesses. The patients with more serious conditions like sepsis or pneumonia should have drawn blood cultures.
The problem is that at the first sight, MRSA infections looks like almost any staph infection so in order to properly identification of MRSA this has to be taken into consideration from the beginning. Otherwise, a common infection becomes suspicious as being MRSA infection is when seems unresponsive to antibiotic treatment.
The definitive and most straightforward diagnosis is given by coagulase laboratories test. If S. Aureus grows in the presence of methicillin, the test is positive for MRSA.
Symptoms of Mercer Infection
Symptoms for MRSA infection are variable. The symptoms will depend very much on the part of the body that is infected. Many people can carry the MRSA infection inside the nose but never experiencing any symptoms.
However seems that pus is commonly found in the areas that are infected. Some examples of areas containing pus are boils, abscesses or sty which is pus in an eyelid gland. The infection found under the skin or in fatty tissue, named Cellulitis, usually begins with small and red bumps and does not have pus; also sometimes are itching.
An MRSA skin infection usually develops as a painful mark in the skin and is looking like an insect bite. The bacteria might enter the skin through a cut or a hair follicle and develops into a painful swelling.
Some people will experience some additional symptoms which can be:
- high temperature
- general feeling of being unwell.
- dizziness and confusion
- muscular pains
- tenderness in the affected body part
If the bacterium penetrate deep inside the patient’s body he will develop signs of an invasive infection which can be:
- blood poisoning
- urinary tract infection
- septic bursitis and septic arthritis
Either children or adults have often the same symptoms. In groups of children they develop the symptoms in a very quick time frame. Groups can be family members or close friends, persons that are around each other all day long. The mentioned symptoms are found in both CA-MRSA and HA-MRSA. When antibiotic therapy is failing, this is a clear sign that we are dealing with a MRSA infection and should be considered as a most probably cause.
HA-MRSA infections are suspected when patients in the hospital that are treated with an antibiotic is developing high fever and chills, low blood pressure which are all signs of sepsis.
CA-MRSA patients who develop signs of pneumonia or sepsis have to be hospitalized immediately. Anyway, patients do not need to have a primary MRSA site infection but only sites that MRSA can invade. As a consequence, symptoms that the pus is produced or even signs of sepsis in those patients that are immune compromise like HIV or cancer patients could be manifesting due to presence of MRSA infection.
