“…Until recently, various names, including S. aucheniae , S. lamacanis and S. lamacenis had been used in different studies [ 15 , 23 , 24 ]. However, recently Dubey et al [ 1 ] proposed that S. aucheniae was the only valid name (as per standard nomenclature) for the Sarcocystis species that forms macroscopic sarcocysts in llamas and alpacas.…”

“…The infected alpacas showed decreased body weight gain and hematocrit levels compared to control groups. A high mortality (92%) was observed in alpacas infected with a high dose of sporocysts [ 23 ]. Histological examination of cardiac muscle revealed that microscopic sarcocysts were located only in myocytes and not in Purkinje cells and they did not cause any interruption in the conduction of electrical impulses through the myocardium [ 24 ].…”

Members of the genus Sarcocystis (Apicomplexa: Sarcocystidae) are intracellular protozoan parasites that infect a wide range of domestic and wild animals, resulting in economic losses in production animals worldwide. Sarcocystis spp. have indirect life-cycles where canids and felids serve as main definitive hosts while a range of domestic and wild animals serve as intermediate hosts, including South American camelids (SACs) such as alpacas, llamas and guanacos. These animals primarily occur in South American countries on Andean, elevated plains but in recent years, alpacas and llamas have become emerging animal industries in other parts of the world such as Australia, Europe and the USA due to their high-quality fiber, meat and hides. For instance, alpaca meat is becoming popular in many parts of the world due to its lower cholesterol content than other red meat, thereby it has the potential of a valuable product for both local and international markets. However, SAC meat can be degraded and/or even condemned due to the presence of macroscopic sarcocysts in skeletal muscles, leading to significant economic losses to farmers. The infection is generally asymptomatic, though highly pathogenic or even fatal Sarcocystis infections have also been reported in alpacas and llamas. Despite the economic importance of sarcocystosis in SACs, little is known about the life-cycle of parasites involved, disease transmission, epidemiology, pathogenesis, diagnosis, control and public health significance. This review article provides an in-depth analysis of the existing knowledge on the taxonomy, epidemiology, clinicopathology and diagnosis of Sarcocystis in SACs, highlights knowledge gaps and proposes future areas of research that could contribute to our better understanding of sarcocystosis in these animals.

“…La sarcocystiosis tiene un impacto negativo en la economía de los productores de alpacas, debido a que la presencia masiva de macroquistes en la musculatura conducen al decomiso de canales, limita la comercialización de la carne y sus proyecciones futuras como fuente de proteínas y mayores ingresos para el productor (Leguía et al, 1990;Leguía, 1991;Carletti et al, 2013;Céspedes et al, 2013.;Chávez et al, 2008;Lucas, 2012). Se ha estimado una pérdida anual de $ 300.000 dólares americanos, sólo por el decomiso de canales infectados (MINAG, 1973).…”

Se realizó un estudio longitudinal prospectivo a fin de determinar la infectividad de los quistes de Sarcocystis sp. en alpacas en una ganadería de la sierra central del Perú. Mediante un diseño randomizado se seleccionaron 50 crías machos de alpacas, un mes después de la parición, los cuáles fueron sacrificados a razón de 3, en forma mensual, desde el nacimiento hasta el año de edad con la finalidad de detectar la presencia de micro o macroquistes en la musculatura esquelética y/o cardiaca. Grupos de perros, libres de parásitos, fueron infectados, mensualmente, con músculo cardiaco y esquelético de alpacas a fin de detectar la presencia de quistes o esporoquistes de Sarcocystis sp. en las heces. Los resultados obtenidos evidenciaron que las crías de alpacas presentaron quistes microscópicos, tanto en la musculatura cardiaca como esquelética a partir de los 4 meses de edad. No se detectó quistes macroscópicos visibles en la musculatura esquelética y/o cardiaca en dichas crías hasta los 12 meses de edad. Los grupos de perros alimentados con músculo cardiaco y/ o esquelético infectados con microquistes de Sarcocystis sp. de alpacas, desde el nacimiento hasta el año de edad no lograron eliminar ooquistes o esporoquistes.

Sarcocystis is a threat to food security in the Peruvian Andes. The Sarcocystis species that forms microcysts in the myocardium of alpacas is S. masoni n. sp. (known as "S. lamacanis"). There is a lack of current studies estimating the prevalence of this parasite in alpacas, although this information is crucial for the control and prevention of sarcocystosis. The aim of this study was to determine the frequency and cyst density of Sarcocystis masoni n. sp. in the myocardium of alpacas in Huancavelica, a province of the Andean region of Peru. Myocardial samples for histological analysis were taken from 104 alpacas slaughtered in an official abattoir in the area. All alpacas (100%) presented this parasite. About 44% (95% CI: 34.5-53.5%), presented from 31 to 45 microcysts per mm2 of myocardial histological slide (cyst density). Cyst density was significantly higher (p<0.05) as the age of the animals increased. In addition, cyst density was significantly higher (p<0.05) in 4- and 5-years-old males compared to females of the same age. These results confirm that myocardial sarcocystosis is highly endemic in alpacas in Peru.
