  • Parasite Paradise: Barber’s Pole Worm in Alpacas

    Humid air, moist grass and mild temperatures are ‘party central’ for the enemies of alpacas – gastrointestinal worms. More alpacas die through parasitic infestation than virtually any other single cause, yet owners often find it difficult to spot the signs of infestation, and improve husbandry to reduce the effects. Many nematode worm species occupy sections in the gastrointestinal tract of your alpacas. From mouth to rectum is a warm, moist, dark space, perfect for feeding, growing and reproducing. Consider it from the worms’ perspective, life could not be better, tucked away with constant warm temperature, food and protection at no cost to them. Of course, as in all ecosystems, and the digestive tract of your alpacas is an ecosystem, there will be competition between worms for the best ‘pitch’. Different species of worm favour different spaces within the tract. The worm must avoid immune responses of the host but in the main the gut is a very hospitable place for worms to survive, hence their success. These insidious parasites share a common objective; to shelter, grow and reproduce within their host, bringing nothing to the party whilst taking all they can. more »
  • Barber’s Pole Worm in Alpacas

    The gastrointestinal parasite Haemonchus spp. is better known as the barber’s pole worm (BPW) because the adult female worm has a white tubular uterus that winds around their blood-filled tubular gut, giving the look of a barber’s pole (Figure 1). This parasite is a blood sucker of domestic livestock, causing anaemia and illthrift and can kill alpacas (and sheep, cattle and goats) quickly and in high numbers. more »
  • Alpaca Parasites

    Alpacas and llamas are susceptible to many of the gastro-intestinal nematodes or “worms” that infect sheep and cattle, including barber’s pole worm (Haemonchus spp) and the scour worms. The behavior of worms in alpacas is not well described and is currently being studied at the University of Melbourne. The project is identifying worm species, worm behaviour, methods of diagnosis/monitoring of worm burdens and worm control in alpacas. In the interim, camelid farmers need to extrapolate from sheep research on how best to control worms. more »
  • 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 »
  • Husbandry: Worms And Alpacas

    Alpacas are susceptible to cattle, goat and sheep worms, however the four most likely to cause problems with alpaca are: Barber’s Pole Worm (Haemonchus contortus) up to 10,000 eggs per day Small Brown Stomach Worm (Ostertagia ostertagi) 100-200 eggs per day Black Scour Worm (Trichostrongylus spp) 100-200 eggs per day Liver Fluke (Fasciola hepatica) 20,000-50,000 eggs per day The eggs are passed out in the faeces and can remain in the paddock for long periods, until warm moist conditions are present and they begin to hatch into infective larvae. Alpacas with a worm burden can be passing eggs in their faeces over winter with the eggs not hatching due to the cold, only to have millions of eggs begin hatching when the warm spring days arrive. This sudden arrival in the paddock of millions of larvae can result in sudden and severe worm infestations with severe consequences. more »
