Lack of effect of immunity to crab chitin on tick infestations of rats and rabbits
1981 - Volume: 22 Issue: 2 pages: 127-131
The effects of administering crab chitin suspensions to rat or rabbit hosts either prior to or concurrently with experimental infestations of Dermacentor variabilis were examined. No significant differences were observed between controls and experimentals for tick attachment, engorgement, detachment or egg production. Direct injections of extracts of chitin or of host antiserum to chitin into female ticks did not affect viability.
