| Fresh faeces offer the best results and are essential for
protozoal examination. Aged faeces, i.e. those from litter trays or lawns
should be avoided as they are unlikely to yield worthwhile results. Fresh
faeces should be placed in a clean container that can be sealed. |

If protozoa are suspected and the sample is not being examined
immediately, keep humidity high by placing a small piece of moistened cotton
wool in the container. For bacterial culture it is better to take a separate
transport swab, especially if Campylobacter or Clostridia spp. are suspected. |

Viruses are usually detected by antigen demonstration i.e.
ELISA or IFA techniques and fresh faecal samples are required. Viral culture
and electron microscopy are not routinely recommended. |

Dry swabs should be avoided as anaerobes and microaerophilic
bacteria cannot be recovered from these. Charcoal media is recommended for
routine work. |
