Prevalence of Eimeria macusaniensis and Eimeria ivitaensis in South American camelids of Northwest Argentina

Effectiveness of coproscopic concentration techniques

“…This is what it was expected, since Trichuris sp. eggs, found in camelids, and E. macusaniensis oocysts are high density structures (Jarvinen, 1999;Cebra & Stang, 2008;Cafrune et al, 2009). Cebra and Stang (2008) suggested that a high specific gravity solution may improve Nematodirus spp.…”

“…Common nematode parasites of domestic ruminants also infect South American camelids (SAC). However, they are frequently parasitized by several specific gastrointestinal parasites, as Lamanema chavezi, Eimeria macusaniensis, Nematodirus lamae and Trichuris tenuis, among others (Leguía 1991(Leguía , 1999Richard & Bishop, 1991;Cafrune et al, 2001Cafrune et al, , 2009Cebra & Stang, 2008). Eggs of L. chavezi and oocysts of E. macusaniensis also exhibit particular features such as their large sizes and high specific gravity (Jarvinen, 1999;Cafrune et al, 2009).…”

“…Additionally important consideration is the selection of those procedures that causes the minimal egg distortion or destruction (O'Grady & Slocomb, 1980;Quinn et al, 1980;Cringoli et al, 2004). Parasitological research on SAC usually utilizes flotation procedures with low specific gravities solutions (δ < 1.3) (Leguía & Casas, 1998;Jarvinen, 1999;Cafrune et al, 2001;Beldoménico et al, 2003;Cebra & Stang, 2008) being probable that some parasites with high density are underscore, as it was suggested for E. macusaniensis or L. chavezi, among others (Jarvinen, 1999;Cafrune et al, 2001Cafrune et al, , 2009Cebra & Stang, 2008). Furthermore, reports evaluating the performance of common fecal diagnostic HELMINTHOLOGIA, 51, 3: 210 -214, 2014 Effectiveness of coproscopic concentration techniques (Jarvinen, 1999;Cebra & Stang, 2008;Cafrune et al, 2009).…”

Llamas and alpacas in Europe: Endoparasites of the digestive tract and their pharmacotherapeutic control

“…Diagnosis of Eimeria spp. infections is usually based on the detection of oocysts in the faeces using flotation techniques (Cafrune et al, 2009). To detect oocysts of E. macusaniensis and E. ivitaensis flotation solutions with a higher specific gravity (1.28-1.30) are required (Jarvinen, 1999;Whitehead and Anderson, 2006;Cafrune et al, 2009).…”

Helmintiasis y Eimeriosis Gastrointestinal en Alpacas Criadas al Pastoreo en Dos Granjas Comunales de la Región Pasco, Perú, y su Relación con el Peso y Condición Corporal

“…E. macusaniensis como agente único o asociado con E. lamae o E. ivitaensis es considerada como altamente patógena (Cafrune et al, 2009). La asociación de estas especies es sinérgica, generando la destrucción del epitelio intestinal luminal, conllevando a una enteritis y diarrea (Cheney y Allen, 1989), mermando la ganancia de peso y, en ocasiones, causando la muerte, estando su severidad asociada al número de ooquistes ingeridos y a la inmunidad de las alpacas (Cebra et al, 2007).…”
