DIFFERENTIAL DIAGNOSIS OF DIARRHEA IN CAMELID CRIAS

摘要

Diarrhea in camelid crias can be a very frustrating situation for both owners and veterinarians. Crias can lose significant body weight (10 - 14%) in 24 hours and be in critical condition prior to owner recognition. Many causes of diarrhea in crias have been reported including Cryptosporidium spp, Giardia spp, Coronavirus/Rotavirus, bacterial, and Eimeria spp. Cryptosporidium parvum occurs in calves greater than 7 days of age but in crias it can be as early as 5 days of age. Giardia spp can occur incrias as early as 14 days of age and is correlated most often with periods of high rainfall or problems with run-off water. Eimeria spp can be seen as early as 21 days of age with Eimeria macusaniensis occurring as early as 36 to 40 days of age. Diarrheain crias less than 5 days of age is most likely to be nutritional (especially if bottle fed) or Gram negative infections.
