Stool Culture

The majority of cases of paediatric gastroenteritis are viral, and even cases of bacterial or protozoal infection, are generally self-limiting.

Stool cultures should not be sent routinely.

Consider sending a stool sample for microscopy, culture and sensitivity (MC&S) if [1, 2]:

  • The child has recently been abroad to an at-risk area
  • The diarrhoea has not improved by day 7
  • There is uncertainty regarding the diagnosis

A sample should be sent if:

  • Septicaemia is suspected
  • There is blood and/or mucus in the stool
  • The child is immunocompromised

In the case of an outbreak, notify and act on the advice of the public health authorities as to what samples should be sent.
