Body Fluid Culture aerobic test, also known as wound culture. It is done to detect the aerobic bacteria in normally sterile body fluids. This is useful for the isolation and identification of the pathogenic micro-organisms present in your body fluids. The pattern of color and growth at the growing area will represent the type of bacteria growing inside your body fluids. May assist in differentiating gout from septic arthritis.
Laboratory reports for cultures test typically name the bacteria being identified during the test. A negative culture is usually reported as "no growth seen in 5 days" or note the presence of normal skin flora only.
If pathogenic bacteria are identified in the culture test, it predicts the source of the infection. An infection is usually caused by a single type of bacteria while wounds might have two or more pathogens causing the infection.
If more than three organisms are found present in the test, it may not be identified as individual bacterial species. In the report, it will mention as "mixed bacterial flora."
This indicates the fact that a mixture of normal flora found on the skin and potential pathogens cultured from a wounded area was not cleansed properly before the specimen was taken.
These type of cases are found in a motorcycle accident where a "dirty wound" is found because of the material from the road has contaminated the wound.
when there is a presence of normal flora, the infection is caused due to the bacteria normally found on the skin.
In an area of the body such as the eye is considered to be essentially sterile, when the wound infection has little growth near the eyes area.
When no bacteria are recovered in the wound specimen, then the pathogen was not successfully recovered with the sample and test.
You are advise to minimize the risk of headache by avoiding any strenuous activities during the day of the procedure. Also try to keep yourself well hydrated. A n over the counter medication, such as acetaminophen (Tylenol), can help you to reduce back pain or headache if there is any.
If the patient is suffering from chronic infection, or in case the wound was exposed to dirty surroundings, treatment with antimicrobial drugs are given for consumption.
In a case when an infection is spread into the blood from the wound, the same microorganisms will be detected in the urine or blood cultures.
