| [fine structure and development of sarcocystis aucheniae in llamas]. | isolated cysts of sarcocystis aucheniae of the llama (lama glama) were fed to one dog and one cat. only the dog excreted sporocysts, measuring 13.1-15.7 (15.0 +/- 0.54) x 9.0-11.3 (10.4 +/- 0.36) micron after 11 days for 21 days. a second cat, which had ingested meat of a llama containing macrocysts of s. aucheniae as well as sarcosporidial cysts visible only under a microscope also did not excrete sporocysts. the cysts of s. aucheniae are surrounded by a folded primary cyst wall forming caulifl ... | 1984 | 6433590 |
| seroprevalence of neospora caninum, toxoplasma gondii and sarcocystis sp. in llamas (lama glama) from jujuy, argentina. | llamas (lama glama) are south american camelids described as intermediate hosts of neospora caninum, toxoplasma gondii and sarcocystis aucheniae. due to the potential role of these protozoan infections as a cause of economic losses, the aim of this study was to determine the seroprevalence for t. gondii, n. caninum and sarcocystis sp. in llamas from argentina. serum samples from 308 llamas (>2 years old) were collected between 2005 and 2007. a total of 55 farms located in six departments of juju ... | 2008 | 18495344 |
| sarcocystis masoni, n. sp. (apicomplexa: sarcocystidae), and redescription of sarcocystis aucheniae from llama (lama glama), guanaco (lama guanicoe) and alpaca (vicugna pacos). | there is considerable confusion concerning the species of sarcocystis in south american camelids (sac). several species names have been used; however, proper descriptions are lacking. in the present paper, we redescribe the macroscopic sarcocyst forming sarcocystis aucheniae and describe and propose a new name, sarcocystis masoni for the microscopic sarcocyst forming species. muscles samples were obtained from llamas (lama glama) and guanacos (lama guanicoe) from argentina and from alpacas (vicu ... | 2016 | 26932444 |
| molecular detection of sarcocystis aucheniae in the blood of llamas from argentina. | sarcocystis aucheniae are apicomplexan protozoa that infect south american camelids (sacs), giving rise to macroscopic cysts similar to rice grains in skeletal muscles. visual detection of macrocysts in slaughtered animals hampers commercialization of sac meat, a highly relevant economic exploitation for andean rural families. importantly, the consumption of undercooked s. aucheniae-infested meat causes gastroenteritis. a carnivore definitive host, possibly the dog, acquires the parasite when fe ... | 2017 | 27615713 |
| molecular identification of sarcocystis aucheniae as the macrocyst-forming parasite of llamas. | the domestic south american camelids (sacs), llama (lama glama) and alpaca (lama paco), are frequently found to be infected with sarcocystis parasites. infections give rise in skeletal muscle to macroscopic cysts (1-5mm long) that resemble rice seeds, each containing several million living bradyzoites. the finding of cysts prevents commercialization of sac meat, an important source of income for rural families in the andean flatlands. thus, development of diagnostic methods to facilitate the con ... | 2013 | 24129069 |
