• First Report of Anthelmintic Resistance in Haemonchus contortus in Alpacas in Australia

    Parasitic nematodes can cause substantial clinical and subclinical problems in alpacas and anthelmintics are regularly used to control parasitic nematodes in alpacas. Although anthelmintic resistance has been reported in ruminants worldwide, very little is known about anthelmintic resistance in alpacas. The present study was carried out to confirm a suspected case of anthelmintic resistance in Haemonchus contortus in alpacas in Australia. more »
  • Alpaca Worms - An Overview

    Alpacas, which are South American camelids, are susceptible to both cattle and sheep internal parasites including liver fluke (Fasciola hepatica). Worms specific to South American camelids, such as Lamanema chavezi, are not known to occur in Australia. Alpacas use dunging ‘latrines’ which can help to control roundworm parasites. As a result, worm burdens are often not high. However heavy barber’s pole worm (Haemonchus contortus) burdens can occur, especially in high rainfall coastal areas in NSW and Queensland. Alpacas are also quite susceptible to liver fluke, possibly due to their relatively small livers. more »
