  • Eimeria macusaniensis Infection in 15 Llamas and 34 Alpacas

    Case Description—15 llamas and 34 alpacas between 3 weeks and 18 years old with fecal oocysts or intestinal coccidial stages morphologically consistent with Eimeria macusaniensis were examined. Nineteen of the camelids were admitted dead, and 30 were admitted alive. Camelids admitted alive accounted for 5.5% of all camelid admissions during this period. Clinical Findings—Many severely affected camelids had signs of lethargy, weight loss, decreased appetite, and diarrhea. Camelids with clinical infection also commonly had evidence of circulatory shock, fat mobilization, and protein loss. Nonsurviving camelids also had evidence of shock, edema, bile stasis, renal insufficiency, hepatic lipidosis, muscle damage, relative hemoconcentration, and sepsis. Postmortem examination frequently re-vealed complete, segmental replacement of the mucosa of the distal portion of the jejunum with coccidial meronts and gamonts. For 17 of 42 camelids, results of initial fecal examinations for E macusaniensis were negative. Treatment and Outcome—Most camelids admitted alive were treated with amprolium hydrochloride, plasma, and various supportive treatments. Fifteen of the 30 treated camelids died or were euthanized. Clinical Relevance—Findings suggest that E macusaniensis may be an important gastrointestinal tract pathogen in camelids of all ages. Clinical signs were frequently nonspecific and were often evident before results of fecal examinations for the parasite were positive. As with other coccidia, severity of disease was probably related to ingested dose, host immunity, and other factors. The clinical and herd relevance of positive fecal examination results must be determined. more »
  • Alpaca Emac - A Lethal Parasite

    Eimeria macusaniensis ( commonly called Emac ) is a type of coccidium seen only in alpacas. There are four types of coccidia seen in alpacas. Emac is rarely seen or identified and even in research very few cases are ever identified. Coccidia as a whole is a necessary part of life in any species, and exposure helps build tolerance and potential immunity. Without this the animal will not survive, as coccidia is everywhere and so if an animal is never exposed to coccidia, they will have no immunity to fight it, because it is impossible that any animal will not be exposed to coccidia at any stage of life. For treatment, if there are less than 100 eggs on a slide, it does not need to be treated with Panacure (SafeGuard). However, Emac, which is type of coccidian, can be lethal and must be treated if you see just one egg. more »
