Lice

The sucking louse Haemodipsus ventricosus can affect domestic rabbits, and it usually found in breeding establishments, especially if husbandry standards are poor. It is a large louse 1.5-2.5 mm in length and can be transmitted by direct contact.

Lice are known to be vectors for tularemia and commonly affects wild rabbits. There is discussion whether or not lice can act as a mechanical vector for myxomatosis.

The entire life cycle of the louse takes 2-3 weeks depending on environment conditions. The organism and eggs can be seen by the naked eye.
