Tuberculosis (TB), due to infection with Mycobacterium bovis was diagnosed in a flock of alpaca in Ireland in 2004. An epidemiological investigation was conducted to identify the risk of TB for farmed alpaca where TB is endemic, the origin of the infection, the potential for alpaca-to-alpaca transmission and appropriate control measures. The investigation focused on the alpaca flock (including ...

This paper studied the wool and alpaca fibre curvature and its variation during the fibre processing. It revealed the effect of wool fibre crimp on the cohesion properties of alpaca and wool blended slivers. Different wool and alpaca tops were blended via a number of gillings, and the role of wool fibre curvature in alpaca/wool blend processing has also been investigated. During the wool fibre ...

The origins of South America's domestic alpaca and llama remain controversial due to hybridization, near extirpation during the Spanish conquest and difficulties in archaeological interpretation. Traditionally, the ancestry of both forms is attributed to the guanaco, while the vicuña is assumed never to have been domesticated. Recent research has, however, linked the alpaca to the vicuña, datin...

This study reports the latest research into alpaca and wool fibres. In particular, those properties that have received little attention in research literature have been examined. They include single fibre abrasion and bending fatigue, single fibre tensile properties, as well as resistance to compression behaviour. These properties are important because they affect the softness and pilling prope...

28 Antigenic group 2 coronavirus was detected in a fecal sample of an adult alpaca by RT-PCR. The 29 presence of alpaca coronavirus (ApCoV) in the small intestine was demonstrated by immune30 histochemistry using an anti-nucleocapsid monoclonal antibody that reacts with group 2 31 coronaviruses. Other common causes of diarrhea in adult camelids were not detected. We conclude 32 that nutritional...

The public profile of the alpaca (Vicugna pacos) increased significantly as it became a more common agricultural species around the world and the focus of more intense modern breeding techniques and of genomic studies. The alpaca is 1 of 7 camelids that together occupy some of the world's most arid ecosystems and which have had large beneficial impacts on the human cultures in these areas. Toda...

The enterotoxins (ETs) of Clostridium perfringens isolated from enterotoxemic or diarrheic alpacas, pigs, calves, dogs, and horses were obtained from sporulated cell extracts. The ETs from alpaca, pig, and calf isolates were chromatographed on Sephadex G-lOO. Monoclonal antibodies (MAbs) against ETs derived from alpaca, pig, and calf C. perfringens isolates were produced. The MAbs were used...

Raising of alpacas as exotic livestock for wool and meat production and as companion animals is growing in importance in the United States, Europe and Australia. Furthermore the alpaca, as well as the rest of the camelids, possesses the peculiarity of producing single-chain antibodies from which nanobodies can be generated. Nanobodies, due to their structural simplicity and reduced size, are ve...

Antigenic group 2 coronavirus was detected in a fecal sample of an adult alpaca by reverse transcription-PCR. The presence of alpaca coronavirus (ApCoV) in the small intestine was demonstrated by immune histochemistry with an antinucleocapsid monoclonal antibody that reacts with group 2 coronaviruses. Other common causes of diarrhea in adult camelids were not detected. We conclude that nutritio...
