How
is it diagnosed
Stool samples are to be collected in C.B. Media & examined
under microscope.
By culture on TCBS (Thiosulfate -Citrate- Bile salts -Sucrose) media for bacterial growth.
Collection and Transport of Stool Samples
| - |
Collect the stool sample before the patient receives
antibiotics. |
| - |
Use a clean cotton tipped swab and introduce well
into the rectum. The swab will become moist and may be faecally
stained. |
| - |
Alternatively, collect freshly passed liquid stool
in a bottle or a cotton tipped swab. |
| - |
Send the sample to the laboratory in a tightly
sealed screw capped sterile bottle if the sample can reach the
laboratory within two hours. |
| - |
Send the sample to the laboratory in a tightly
sealed screw capped sterile bottle with Cary-Blair transport
medium(or VR medium or Alkaline Peptone Water) if it will take
more than two hours to reach the laboratory. |
| - |
If transport medium is not available , soak strips
of blotting paper with liquid stool. Send these to the laboratory
in carefully sealed plastic bag to prevent drying. |
| - |
Send the samples using a cold chain. |
| - |
Bottles or plastic bags should be placed in separate
plastic bags each to prevent leakage of the potentially contaminated
material. |
| - |
Each sample should be labelled. Detailed information should
be sent for each sample.
