Sample submission
- Samples for egg counts
Place samples in a sealed container. Samples can be sent in a container with a screw cap, or plastic bank bags can be used. Samples must be clearly marked, preferably with a ballpoint pen that will not smear when the container gets wet. Send approximately 4g of faeces (one heaped teaspoon) for each test required, i.e. when and egg count and a fluke examination is required, send in 8g of faeces. Faeces must be collected from the rectum and not picked up from the ground. Take separate samples of each animal that must be tested.
Samples should be kept cool until it reaches the laboratory. It can be kept in the refrigerator, but do not freeze the samples. - Samples for larval culture
When a larval culture and larval identification is required, a sample can be taken from the flock as a whole. Take a representative sample, i.e. the same amount of faeces from each animal being sampled. A minimum of 50g of faeces is required for the test, but a larger sample will make the test easier. Keep the sample cool until it reaches the laboratory. - Worms for identification
Worms must be collected either in 10% formalin or in 70% alcohol. If above is not available, worms may be collected in metholated spirits. Place the specimens in a container with a screw cap that seals tight, so that the contents does not leak out. - External parasites for identification
Parasites must preferably be collected in 70% alcohol or 10% formalin, but methylated spirits can also be used. Place parasites in a container with a screw cap that seals tightly.
If live parasites like ticks are sent, ensure that the parasites cannot escape from the container they are sent in.
- Information of the referring veterinarian, or veterinarian that is normally used by the client, must be included.
- In the case of parasites that are sent for identification, state the part of the body from which the parasite was collected.
- History of any previous drenches or anti-parasitic treatment must be included. Date of treatment, as well as remedy used and dose administered, must also be included.
The above information helps with administration and may be of diagnostic value.
