| STOMACH DISEASES | | The Acute Abdomen in South American Camelids | | South American Camelids (llamas, alpacas) may represent a significant financial investment for the owner, but they are viewed most commonly as pets, companions, or valued friends. Veterinarians should be aware of potential life-threatening lesions associated with the acute abdomen (colic). Camelids demonstrate clinical signs of abdominal pain similar to those seen in true-ruminants (depression, recumbency, abnormal posture) and horses (kicking at the abdomen, rolling). Clinicians working with camelids must become familiar with the normal activity, anatomy, physiology, and diseases common to these interesting patients.

Do not change social structure of groups. Leave animals that have established a social order together. Stop all new activity on farm (e.g. show fitting and testing, re-grouping for sale, introduction of new animals, removal of animals).
Evaluate all feed and water sources. Remove any suspect hay or grain sources (e.g. molded, spoiled, etc). Clean and sterilize any water containers that appear to contain algae or are not clean. Inspect all water sources for evidence of dead animals, run off, etc.
David E Anderson, D.V.M., MS, Diplomate ACVS, College of Veterinary Medicine, The Ohio State University | | | DISEASES: AN OVERVIEW | | Parelaphostrongylus Tenuis (Meningeal Worm) Infection in Llamas and Alpacas | | The meningeal worm (Parelaphostrongylus tenuis), also known as the deer worm or meningeal deer worm, frequently infects llamas and alpacas. Aberrant migration of the meningeal worm in susceptible hosts such as llamas and alpacas causes damage to the central nervous system and may result in death.
David E Anderson, DVM, MS, Associate Professor, Department of Veterinary Clinical Sciences, College of Veterinary Medicine, The Ohio State University | | | LIVER DISEASES | | LIVER DISEASE, METABOLISM, AND DIGESTION IN LLAMAS AND ALPACAS | | The incidence of liver disease in llamas and alpacas is unknown, but this disease appears to be common in North America. In a survey of llamas and alpacas admitted to the Veterinary Teaching Hospital at Ohio State University between January 1, 1993 and December 31, 1995, 19 cases of liver disease were found (Table 1).

What do we do? | | Facial swellings increasingly are recognized in Alpacas across North America. There are several possibilities for facial swellings that you should be aware of. First, animals that are disturbed while eating may retain their cud, or food bolus, in the side of their cheek for some time. This swelling is soft and indentable and will disappear soon after the animal returns to normal activities.

Although fatty liver disease is often discussed or observed during necropsy examination, primary liver diseases have been infrequently diagnosed. Recent clinical data suggest that the cause of fatty liver disease may have been overlooked in many camelids. David E Anderson, D.V.M., MS, Diplomate ACVS, College of Veterinary Medicine, The Ohio State University, Columbus, Ohio | | | DISEASES: AN OVERVIEW | | Biosecurity for Camelid Owners | | In response to a request in 2006 from the chair of the U.S. Animal Health Association’s Committee on Infectious Diseases of Cattle, Bison and Camelids, Karen Conyngham (ILR representative to USAHA) compiled a short overview of biosecurity practices that should be followed by all camelid owners. The PowerPoint presentation draws heavily on the excellent articles written by Dr. Kristy Brown of Wisconsin on this topic, and also incorporates some points from articles in the peer-reviewed literature plus several suggestions by veterinarian members of the USAHA Committee.
