Trichuris trichiura, Whipworm

Trichuris trichiura is a whipworm that can be detected in stool. It is an intestinal worm and is not considered a normal part of the dog’s gut microbiome. Trichuris trichiura is mainly known as a human whipworm, while dogs are more typically associated with other Trichuris species. A finding in a dog sample should therefore be interpreted carefully. Exposure may reflect contact with whipworm eggs from faecally contaminated soil, grass, dog areas, kennels, or other environments where infected faeces may have been present. Whipworm eggs can persist in the environment for a long time. Whipworms mainly affect the large intestine and caecum, where they can attach to the intestinal lining and may irritate it. Relevant findings may be associated with diarrhoea, mucus or blood in stool, straining, altered stool quality, weight loss, reduced appetite, or poor general condition. A positive finding may be useful to review with a veterinarian, especially if large bowel signs, possible exposure to contaminated ground, or repeated digestive issues are present.
