Eimeriid Oocysts From Archaeological Samples in Patagonia, Argentina

A review of coccidiosis in South American camelids

“…Temperature of incubation can also affect sporulation; E. macusaniensis oocysts sporulated in 9 days at 30°C, in 21 days at 18-25°C but oocysts did not sporulate at 6-7°C (Rohbeck 2006). 2015); shape and sizes of these oocysts were remarkably preserved (Fugassa et al 2008). Similar findings are reported for coprolites from Chile dating to Pre-Inca Hispanic Contact Period (de Souza et al 2018).…”

Ampliación de los estudios parasitológicos en camélidos del sitio arqueológico Cerro Casa de Piedra 7, Santa Cruz, Argentina

“…Eimeria macusaniensis es un coccidio eimeriido específico de camélidos sudamericanos. Su presencia desde la Transición Pleistocénica en Patagonia (Fugassa et al 2008) demuestra una asociación antigua con los camélidos. En guanacos, E. macusaniensis fue hallada en pocos estudios (Beldomenico et al 2003;Cafrune et al 2009;Castillo et al 2008;Correa et al 2012;Jarvinen, 2008;Moreno et al 2015) y en Patagonia, solo fue reportado en Chubut (Beldomenico et al 2003) y Chile (Ruiz Aravena & Correa, 2010).…”

Disorders of the Digestive System

“…As such, they resemble E. leuckarti of horses, E. camelli of camels, and other large Eimeria. 119 than it is wide without a clearly visible polar cap (by standard light microscopy), whereas E. lamae is about 60% longer than it is wide and has an obvious cap (Figure 40-35). Both have an obvious polar cap.…”
