Stool Culture + Sentry Air Systems

What is Stool Culture?

Stool culture is the process of testing a sample of stool in order to determine whether you have an infection in your lower digestive tract due to pathogenic germs such as bacteria, fungus, viruses, or protozoa. This test is used to identify the various types of bacteria that can cause disease and differ from the normal bacteria in the digest tract, gut flora.

When is Stool Culture Necessary?

Certain bacteria and germs can cause a severe disruption in one’s normal gut flora resulting in irregularities in their lower digestive tract such as diarrhea, abdominal cramps, nausea, and /or vomiting. When these symptoms last longer than a few days or the frequency occurs more than usual it is best to seek the advice of a doctor or medical professional. In most cases, a sample will be taken to test your bacteria levels in your stool where they are a reflection of the bacteria represented in your digestive system or gastrointestinal tract.

Unfortunately, pathogenic bacteria can be found in the most common of sources, such as food and drinks, if not handled correctly or not cooked thoroughly enough. Examples of common sources that may carry unhealthy bacteria into your digestive tract are:

• Raw/ Undercooked Eggs
• Raw/ Undercooked Poultry
• Raw/ Undercooked Beef
• Raw/ Undercooked Seafood
• Expired Vegetables/ Fruit

• Untreated water
• Overindulgence of citrus
• Artificial sugar
• Overindulgence of fiber
• Dairy Product

Stool Culture and Sensitivity Procedures

Stool Samples (Source)

Sensitivity procedures (sensitivity analysis, susceptibility testing, sensitivity testing) are used by medical professionals to dictate the correct antibiotic treatment for an infection, inflammation, or contamination. Due to certain bacteria being resistant to common antibiotics, meaning the prescription can’t kill the bacteria, sensitivity analysis may be ordered to assist the doctor to see if the bacteria causing the infection is resistant to the treatment.

• Susceptible – Bacteria cannot grow if the antibiotic is present and is effective against the infection

• Intermediate – A higher dose of the antibiotic is needed to prevent the growth of the bacteria

• Resistant – Bacteria can grow if the antibiotic is present and is ineffective against the infection

Safety Protocols for Stool Sample Testing

Lab technicians and medical personnel working with stool specimens often face potential health hazards including, but not limited to, ingestion of bacteria and germs, ingestion of eggs or cyst, infection, penetrated skin by larvae, and various respirable infections and viruses. While these risks carry a wide spectrum of health hazards, they can be minimized by implementing safety precautions and secondary engineering controls; such as:

• Wear PPE – Safety Goggles/ Glasses | Gloves | Laboratory Coat
• *Utilize biological safety cabinets or personalized cleanrooms
• Remove all personal items from the immediate work area
• No eating, drinking, smoking, application of cosmetics, or manipulation of contact lenses or glasses in the work area
• Disinfect and decontaminate work area daily and after any spill or exposure to the surface area or material and tools used
• Before leaving the work area, ensure that all PPE is removed and hands are washed before returning to the regular environment
