The number and variety of microorganisms inhabited in the intestines of normal people constitute an in vivo micro-ecological environment that is extremely important for human health - micro-ecological membrane barriers, participating in nutrition, digestion, absorption and cleaning of the intestines, and maintaining health. When pathogens and viruses multiply in the intestines, they can cause abdominal pain and diarrhea. Bacterial culture of feces can isolate pathogenic bacteria causing abdominal pain and diarrhea from a large number of intestinal bacteria for timely treatment.

Basic Information

Specialist classification: Infectious disease inspection and classification: feces / parasitic examination

Applicable gender: whether men and women apply fasting: not fasting

Analysis results:

Below normal:

Normal value:
no

Above normal:

negative:
There are no pathogens in normal feces.

Positive:
Pathogenic bacteria such as Staphylococcus aureus, anaerobic streptococci, typhoid and other Salmonella can be seen in the feces, and the disease and treatment plan can be determined according to the pathogenic bacteria.

Reminder: Fecal specimens should be collected in the early stages of the disease and before the antibiotics start treatment. At this time, the pathogens are abundantly present in the feces. Normal value

There is no pathogenic bacteria growth in normal human feces.

Clinical significance

Abnormal results:

Common intestinal pathogens in feces.

Gram-positive bacteria include Staphylococcus aureus, anaerobic streptococci, Mycobacterium tuberculosis, Candida albicans, Clostridium perfringens, Clostridium difficile, and the like.

Gram-negative bacteria include typhoid and other Salmonella, Shigella dysenteriae, pathogenic Escherichia coli, Vibrio, Aeromonas, Alternaria, Yersinia enterocolitica, Campylobacter.

These bacteria can cause intestinal diseases, such as typhoid typhoid fever; various Salmonella causes enteritis; Shigella causes dysentery; pathogenic Escherichia coli and Campylobacter cause diarrhea. If the fecal culture is found to be a strong infectious disease, such as cholera and paracholera, the local epidemic prevention department should be promptly reported and the patient should be immediately isolated.

Need to check the crowd:

Diarrhea, abdominal pain, suspected bacterial infection, especially with symptoms such as fever.

Positive results may be diseases: bacterial dysentery, toxic bacterial dysentery, gastroenteritis caused by rotavirus, gonococcal anorectitis, rotavirus enteritis, adenoviral enteritis, pediatric E. coli enteritis, pediatric bacterial dysentery , other children with Salmonella infection, astrovirus gastroenteritis precautions

Requirements for inspection:

1. The stool specimen should be collected in the early stage of the disease, and the antibiotics are collected before the treatment begins. At this time, the pathogen is abundantly present in the feces.

2. Bacterial culture, isolation and susceptibility testing were performed together.

Preparation before inspection:

1. It should be checked immediately after defecation. From the pus and soft parts, the cold season specimens need to be kept warm during transmission and inspection.

2. Inform the doctor if they have been to the epidemic area and have been exposed to the infected water.

Not suitable for people:

There is no inappropriate crowd.

Inspection process

The diagnostically significant part of the feces was selected and cultured in the medium, cultured at a suitable temperature for 7 days, the population was observed, and the population type was examined by microscopy. A counting plate was used to record the approximate number of bacteria in the bacterial population.

Not suitable for the crowd

No taboos.

Adverse reactions and risks

Generally no complications and harm.
