Coccidiosis and gizzard erosion are rare conditions in cage bird. A male zebra finch was presented with a history of watery diarrhea, anorexia, ruffled feathers, weight loss, and lethargy and died finally. Gross necropsy revealed small areas of erosions and hemorrhages on the gizzard wall. The intestine was oedematous. The spleen appeared pale and small. The testes were asymmetric.Histologicall...

In order to determine the involvement of nitric oxide in the pathogenesis of coccidiosis induced by Eimeria, 30 chickens were challenged with mixed sporulated oocysts of four species of Eimeria (E. acervulina, E. maxima, E. necatrix, and E. tenella) at 26 days of age. There was an increasing of oocyst shedding in the infected birds at 6, 10 and 14 days post-infection. Histopathological examinat...

This study was conducted to compare the gene expression profiles, after Eimeria maxima infection, between 2 B-complex congenic lines of Fayoumi chickens that display differences in disease resistance and innate immunity against avian coccidiosis using cDNA microarray. When compared with uninfected controls using a cutoff of >2.0-fold alteration (P < 0.05), M5.1 demonstrated altered expression o...

Day-old turkeys poults were given a live coccidiosis vaccine via the eye at the hatchery, and all poults produced oocysts in their droppings 7 d later. No oocytes were present in droppings of unvaccinated controls. The weight gain of vaccinated poults challenged at 3 wk of age with a mixture of three species of Eimeria was lower than that of unchallenged poults, indicating that they were suscep...

This report documents the first case of biliary coccidiosis in the ferret. Multiple life stages of a coccidian parasite, including meronts, gametocytes, and oocysts were present in the epithelium of hepatic bile ducts and the gallbladder. Based on morphologic characteristics, the organisms were identified as Eimeria sp., most likely E. furonis.
