  • Objective—To develop a PCR assay for Candidatus Mycoplasma haemolamae (CMhl) infection in alpacas and use it to study the efficacy of oxytetracycline treatment and development of a subclinical carrier state. Animals—8 healthy adult alpacas. Procedures—Alpacas initially had negative results for CMhl in blood samples via PCR assay and were experimentally infected with CMhl; 4 were treated with oxytetracycline, and 4 were not treated. All were monitored regularly via PCR assay, blood smear examination, PCV, rectal temperature, and physical examination. At 6 months after treatment, all alpacas were immunosuppressed by administration of dexamethasone and tested for CMhl. Results—7 of 8 alpacas had positive PCR assay results 4 to 6 days after experimental infection. When organisms were detectable on a blood smear, they were seen 2 to 6 days after positive results of PCR assay. Infection was often associated with mild anemia that was usually transient. No alpacas became hypoglycemic. Oxytetracycline treatment was not associated with faster clearance of organisms or resolution of anemia, and 4 of 4 treated alpacas still had positive results of PCR assay when immunosuppressed 6 months later; 0 of 3 nontreated alpacas had positive results of PCR assay following immunosuppression. Transient fever was detected in 3 alpacas during immunosuppression. Conclusions and Clinical Relevance—The PCR assay was more sensitive than blood smear examination for detection of infection. Clinical signs, anemia, and fever were not necessarily associated with infection. Oxytetracyline administration did not consistently clear CMhl infection. Although treated with oxytetracycline, infected alpacas remained chronic carriers. more »
  • Coccidiosis is a parasitic infection of alpacas that can also be found in a wide variety of other animals such as cows, poultry, and dogs. The cause of the disease is the infestation of the intestines of the alpaca by a parasitic protozoan. Symptoms of coccidiosis in alpaca include dehydration and loss appetite. There can also be diarrhoea, possibly with blood in it. Medication is available for treatment of coccidiosis in alpaca. But good management techniques should also be introduced to prevent outbreaks. more »
  • It is important to note that currently available ivermectin injectables and topicals do not work well in these species as the physiological makeup of their skin is different than other ruminant/semiruminant species. Chorioptes bovis can be found on several species and all potential sources of infestation must be considered (cattle, horses, etc.). more »

  • There are solutions to the spread of BVDV and other infectious diseases. We can extrapolate from other livestock species’ proven methods to protect and treat alpacas. Finally, we can develop alpaca-specific, protective protocols and treatments. more »
