'''Eggs'''<br/>

The eggs of '' Trichuris species are yellow/brown in colour and are bioperculated (have a plug in each end). They are hardy eggs and in the correct coonditions can survive on pasture for up to 12 years. The ''Trichuris'' embryo develops inside the egg and is infective as the 1st larval stage living within the egg.<br/>

==Clinical==

==Pathogenesis==

 

Adult worms bury the thin anterior into the intestinal mucosa and feeds on tissue secretions from the damaged cells rather than blood. The invasion of the worm causes [[Eosinophil|eosinophilia]] in the host animal as it mounts an immune response against the worm. The most common clinical signs are:

* Adult buries its thin anterior half into the intestinal mucosa and feeds on tissue secretions (not blood).  

* Diarrhoea

** The caecum and colon are the most commonly infected sites.

* [[:Category:Enteritis, Catarrhal|Catarrhal enteritis]]

** Causes eosinophilia.

* Anemia

*Signs may include:

* Dehydration

** Diarrhoea
