Camelids (llama, alpaca, vicunãs, guanacos) are important for the economy of South America and Eimeria infections are an important cause of mortality in camelids. Of the six species of Eimeria in camelids, Eimeria macusaniensis, considered the most pathogenic, is distinctive; its oocysts are the largest among all Eimeria species in animals, its prepatent period is more than 1 month, and its oocysts have been found in mummies from prehistoric times. Although, E.

Histopathologically, enteritis of varying intensity was diagnosed in 64 of the pigs. Of these 64 animals, 34 (18%) were infected with both PCV2 and L.

Grewia tenax roots, leaves, juice and fruit decoctions have been used in Africa and Southeast Asiatic countries for a variety of medical purposes. In this investigation, we report the effect of aqueous extract of Grewia tenax fruit (AEGTF) on the variation in vitro of iron absorption. The incubation of freshly prepared rat everted gut sac (EGS) in Ringer medium containing FeSO(4) in the absence of AEGTF showed that in stomach there is iron absorption only at 15 min of incubation time, whereas, at duodenum and jejunum, iron uptake occurs just after 1 min of incubation time and the maximum of iron absorption is registered at 15 min of incubation time.
