Sputum is the substance that comes up from the respiratory tract during coughing. A sputum culture analyzes the sputum for the presence of bacteria, cell fragments, blood , or pus. People who can cough can usually provide a sputum sample easily.
Those who are unable to cough or who are on ventilators may need to undergo a respiratory lavage or bronchoscopy to obtain a sputum sample. Respiratory lavage and bronchoscopy involve the use of a bronchoscope, which is a thin tube with a camera attached.
Under controlled conditions, the doctor inserts the bronchoscope through the mouth and into your lungs. The bronchoscope allows the doctor to see the lungs clearly and to collect a sputum sample for testing.
To do this, urine is collected in a sterile cup during urination. The cup is then given to the doctor, who sends it to a lab for analysis. Sometimes, urine must be collected directly from the bladder. To do this, the healthcare provider inserts a sterile tube called a catheter into the bladder. Urine then drains from the bladder into a sterile container. A blood culture requires taking a blood draw and placing the blood on a dish in a laboratory. If bacteria grow on the dish, doctors can more easily identify what bacteria type is causing infection.
Results from blood cultures typically take about 48 hours. A positive test result can indicate the blood infection sepsis. Bacteria can enter the blood from infections located in other parts of your body, such as the lungs , bones , and urinary tract. These infections usually require antibiotics through an IV , sometimes for long periods of time depending on the severity of your infection.
If you have a large enough skin infection, your doctor may decide to perform an incision and drainage. Incision and drainage are typically performed in an office setting under local anesthesia. Your doctor will use a scalpel to cut open the area of infection and drain it completely. Athletes, daycare and school students, military personnel in barracks, and those who receive inpatient medical care or have surgery or medical devices inserted in their body are at higher risk of MRSA infection.
Vital Signs: Staph infections can kill [ Mins] external icon. MRSA is usually spread in the community by contact with infected people or things that are carrying the bacteria. This includes through contact with a contaminated wound or by sharing personal items, such as towels or razors, that have touched infected skin. The opioid epidemic may also be connected to the rise of staph infections in communities. People who inject drugs are 16 times more likely to develop a serious staph infection.
More about injection drug use and risk of infection on this factsheet pdf icon [PDF — 2 pages]. The symptoms of a MRSA infection depend on the part of the body that is infected. For example, people with MRSA skin infections often can get swelling, warmth, redness, and pain in infected skin.
In most cases it is hard to tell if an infection is due to MRSA or another type of bacteria without laboratory tests that your doctor can order. Some MRSA skin infections can have a fairly typical appearance and can be confused with a spider bite. However, unless you actually see the spider, the irritation is likely not a spider bite.
Most S. Horizontal prevention aims to reduce the burden of all microorganisms. This includes techniques such as hand hygiene, antimicrobial stewardship, CHG bathing, and environmental cleaning methods to decrease colonization of all MDROs in hospital rooms.
Compared with vertical prevention strategies that use active surveillance testing for colonization and CP, horizontal interventions are the most effective means to reduce transmission of MDROs. CHG bathing has also been studied across multiple patient settings for reducing MRSA and VRE acquisition, catheter-associated urinary tract infections, and central line-associated bacterial infections.
SHEA recently released recommendations for timing of discontinuation of CP for patients with MDROs and emphasized that hospital systems must take an individual approach to discontinuing CP that takes into account local prevalence, risk, and resources.
The other side is knowing when it is appropriate to discontinue CP. In addition, CP are expensive and associated with increased rates of patient adverse events. Hospitalists can lead the effort to ensure optimal hand hygiene and work with local infection control teams to reevaluate the utility of CP for patients with MRSA and VRE. This can allow the infections to spread and sometimes become life-threatening.
MRSA infections may affect your:. Visitors and health care workers caring for people in isolation may need to wear protective garments. They also must follow strict hand hygiene procedures. For example, health care workers can help prevent HA-MRSA by washing their hands with soap and water or using hand sanitizer before and after each clinical appointment.
Hospital rooms, surfaces and equipment, as well as laundry items, need to be properly disinfected and cleaned regularly. Mayo Clinic does not endorse companies or products.

Overview Methicillin-resistant Staphylococcus aureus MRSA infection is caused by a type of staph bacteria that's become resistant to many of the antibiotics used to treat ordinary staph infections.
