Eimeriosis en Crías De Alpacas: Estudio Anátomo Histopatológico en Una Golden Retriever

Abstract

The death associated with diarrhea of 7 newborn alpacas from the Maranganí-Cuzco community was studied. The animals showed signs of reddish watery diarrhea, dehydration, anorexia, and weakness. The gross lesions in the small intestine mucosa were reddish, augmented and necrotic, with severe hiperemia and gas. They showed small white foci of 0.2 cm diameter located at the final part of yeyuno and ileon. Two types of oocysts were detected. The first was piriform-shape of 90 microns (Eimeria macusaniensis) and the second, elipsoidal-shape of 30 microns (Emeria lamae). Microscopic lesions presented an acute, diffuse, and severe catarrhal necrotic enteritis with hiperplasia of Lieberkun cripts, and thickness or shortness of the villi, with moderate to severe corionic infiltration of eosinophils, linfocites and plasmacites, along with numerous endogenous forms: schizonts, microgamonts, macrogamonts, and nonsporulated oocysts at level of the crypts and villi.

Probiotic administration modifies the milk fatty acid profile, intestinal morphology, and intestinal fatty acid profile of goats

“…2 EPA = eicosapentaenoic acid; DHA = docosahexaenoic acid. one of the main parasites found in goats (Palacios et al, 2004) that cause coccidiosis. These results are in agreement with previous studies that indicate a decrease in parasitic infection after probiotic supplementation in animals (Draksler et al, 2004;Ross et al, 2010).…”

Disorders of the Digestive System

“…Hence, adults must be considered a possible, if minor, source of infection. 109,115 Histologically, lesions are most pronounced in the villi. In smaller herds with sporadic cases, other infected species may by introducing the parasite.…”

Prevalencia de Eimeria spp en Alpacas de Dos Comunidades del Distrito de Macusani, Puno, Perú

“…Las mayores predominancias de E. lamae (5.1%) y E. macusaniensis (29.0%) en alpacas menores de 1 año son un claro indicativo que muchos animales podrían estar infectados con estas dos eimerias, cuya asociación es altamente patógena (Palacios et al, 2004). E. lamae destruye el epitelio intestinal y E. macusaniensis causa atrofia y necrosis de las glándulas crípticas, ocasionando una diarrea hemorrágica que conduce a deshidratación, anemia, cólico, inapetencia y, por último, la muerte del animal (Leguía y Casas, 1999  Las especies de eimeria encontradas fueron E. punoensis, E. alpacae, E. lamae, E. macusaniensis y E. ivitaensis.…”

“…La asociación de especies más patógena es E. macusaniensis con E. lamae (Palacios et al, 2004), la que ocasiona inflamación de la mucosa intestinal, abundante mucosidad y epitelio descamado con presencia de sangre, afectando la absorción de nutrientes y, por tanto, el rendimiento productivo de las alpacas (Ramírez et al, 1998). La presentación subclínica es la más común en adultos, en tanto que en crías se presenta mayormente en forma clínica (Fowler, 1998) Rosadio et al, 2012).…”
