Clostridium perfringens type A enterotoxemia has been identified as the leading cause of neonatal alpaca mortality in Peru (Ramírez, ).

Alpacas need long-stemmed roughage pasture, hay, silage greater than 4 cm in length to keep the forestomachs functioning normally.

Abortion due to EHV1 has not been described in camelids. Some animals are chronic poor-doers for months before perforation, but most are outwardly completely healthy before perforation.
Blood smears should be made soon after drawing the blood, because the organisms fall off the erythrocytes during transit of the sample to the laboratory. Three of these alpacas were between 1 and 2 years of age; one was 4 years old alapcas one was 6 years old.
So it may be advisable to do plasma selenium testing in this species, instead of, or in addition to whole blood GSHPx. However if present in large numbers they may cause sufficient irritation of the caecal mucosa to result in diarrhoea, perhaps accompanied by mucus enterrotoxemia blood. Generic causes include starvation, low-protein diet, stress. A variety of streptococcal species may be isolated from abscesses in camelids.

Diseases are listed for each syndrome, but are not a complete list of possible causes. What appears to trigger them to cause disease is a change in the diet of the animal. Obesity due to overfeeding may predispose. In crias the most common sign is abnormal angulation of the carpus or tarsus. Five-in-one Clostridial vaccine wn unlikely to provide protection against this enterotoxaemia. Infection with BVD virus is more likely to occur when alpacas are run with cattle. Although not the subject of this article, for long term herd health ennterotoxemia is important that the following fundamental elements are in place: Mycobacterium paratuberculosis believed to be cattle strain was diagnosed in an alpaca herd in Victoria in Camelids are considered to be at low risk for developing clinical signs of West Nile virus infection, however the mortality rate in affected animals showing neurological signs is high.
They vary in size from 0.
Enfermedades infecciosas de las alpacas. Gastrointestinal worms of imported alpacas were mostly eradicated during quarantine, prior to entry into Australia.

Predisposing causes include increased access to grain or abrupt dietary changes with reduced fibre intake. Alpaca feet have two digits like ruminants, however they do not have hooves. Affected animals usually are unable to right themselves from lateral recumbency 1. Young animals are more at risk. Poisoning is associated enterofoxemia a chronic hepatopathy.
Deaths are usually associated with mustering. The carpus may be slightly swollen or painful to palpation. No cases of botulism have been reported in South American camelids, but there is good reason to believe that all camelids may be susceptible 1.
