![]() In order to do this, a pure culture (isolate) of the identified bacteria must be available, which may require additional time in the laboratory to separate and identify each bacterial species. With this information and additional biochemical tests, the types of bacteria present can be identified.įor many of the pathogens identified in the wound culture, antimicrobial susceptibility testing is required to guide treatment and to determine whether the strain of bacteria present is likely to respond to specific antibiotics. Under the microscope, the bacteria can be classified into Gram-positive and Gram-negative organisms and by shape into cocci (spheres) or rods. One such test, the Gram stain, involves smearing individual colony types onto glass slides and treating them with a special stain. Identification is a step-by-step process that may involve many tests and evaluations performed on the bacteria found growing in the culture. ![]() The next step in the process is to identify the different types of microorganisms present. Care must be taken when handling the samples so that their growth is encouraged and the probability of their detection and identification are optimized. Some bacteria infecting a wound may require air for growth ( aerobic) while some require a no-oxygen or reduced-oxygen environment ( anaerobic or microaerophilic). ![]() Since wounds may be superficial or involve deep tissue, they may harbour different types of bacteria that have different requirements for growth. In some cases, for instance with a human or animal bite, there may be several pathogens present. Typically if a person has a wound infection, there will either be a pure culture of the microorganism - only one kind will be found, or one type will predominate. The media encourages the growth of bacteria that may be present, allowing for further testing and identification. A culture helps to determine which type or types of bacteria are causing an infection, and which antibiotic would best treat the infection and help heal the wound.Ī culture is performed by collecting a sample of fluid, cells or tissue from the wound and placing it on or in appropriate nutrient media. Any wound may become infected with a variety of bacteria. Wounds may be superficial breaks in the skin such as scrapes, cuts and scratches or may involve deeper tissues such as incisions, bites, punctures or burns. We are not a laboratory and are unable to comment on an individual's health and treatment.Ī bacterial wound culture is a test that is used to detect and identify pathogenic bacteria in a potentially infected wound. Lab Tests Online-UK is an educational website designed to provide patients and carers with information on laboratory tests used in medical care. If you are concerned about your test results, you will need to arrange an appointment with your doctor so that all relevant information including age, ethnicity, health history, signs and symptoms, laboratory and other procedures (radiology, endoscopy, etc.), can be considered. If the doctor wants to see you about the result(s), you will be offered an appointment. Your GP practice will be able to provide specific details. If you are registered to use the online services of your local practice, you may be able to access your results online. The X-ray & scan results may take longer. Some specialist test results may take longer, if samples have to be sent to a reference (specialist) laboratory. On average it takes 7 working days for the blood test results to come back from the hospital, depending on the exact tests requested.
