Rabbit coccidiosis causes great economic losses to world rabbitries. Little work has been done considering genetic manipulation on the etiological agents, rabbit Eimeria spp. In this study, we constructed a transgenic line of Eimeria magna (EmagER) expressing enhanced yellow fluorescent protein (EYFP) and red fluorescent protein (RFP) using regulatory sequences of Eimeria tenella and Toxoplasma...

A number of complex processes are involved in Eimeria spp. survival, including control of sporulation, intracellular invasion, evasion of host immune responses, successful reproduction, and nutrition. Proteases have been implicated in many of these processes, but the occurrence and functions of serine proteases have not been characterized. Bioinformatic analysis suggests that the Eimeria tenell...

The chickens of local rocks breed were grown in the vivarium Institute Zoology up to 20 days age. Chickens fed with standard bird combined feed for broilers. For studying dynamics hematological parameters blood pockmarked infected E.tenella and treated Artemisia absinthium divided into three groups birds each. first group not (control). second third dose 20,000 sporulated oocysts. was (control ...

Two trials utilizing two corn diets and four wheat diets were conducted. In Trial 2, all chicks were crop-infused at 9 d of age with Eimeria acervulina. In both trials, a broth culture of Clostridium perfringens was mixed with the diets for 3 consecutive d. Necrotic enteritis lesion scores were lowest in chickens consuming the corn diet with no C. perfringens and highest in chickens fed the whe...

Eimeria species are frequently found in water buffalo (Bubalus bubalis) in Brazil. Here, we report those Eimeria spp. that infect buffalos during their first year of life. Fresh fecal samples were examined from 2 groups (1 group/yr for 2 yr, 2000-2002), each with 18 water buffalo calves (both sexes), from birth through 12 mo of age, in Selvíria, MS, Brazil. Five oocyst morphotypes were observed...

Due to an increasing demand for natural products to control coccidiosis in broilers, we investigated the effects of supplementing a combination of ethanolic extracts of Artemisia annua and Curcuma longa in drinking water. Three different dosages of this herbal mixture were compared with a negative control (uninfected), a positive control (infected and untreated), chemical coccidiostats (nicarba...

DE VOS, A.]. & DOBSON, LYNNE D. Eimeria chinchillae DeVos & Vander Westhuizen, 1968 and other Eimeria spp. from three South African rodent species. Onderstepoort ]. vet. Res., 37 (4), 185-190 (1970). Eimeria chinchillae DeVos & Vander Westhuizen, 1968, an organism originally described from the chinchilla and subsequently shown to be transmissible to other rodents, was found to occur naturally i...

A three-year-old elk was necropsied in Kampinos Forest, near the village of Granica. An analysis of a 3g faecal sample from the animal revealed the presence of 130 oocysts of Eimeria catubrina. The parasite is typical of roe deer; this study is only the second reported observation of E. catubrina in elks. As coccidia are so rarely found in elks, this observation of E. catubrina in this new loca...

Fifteen fecal samples from peacocks (Pavo cristatus) in Saudi Arabia contained oocysts of Eimeria riyadhae n. sp. in two peacocks and oocysts of E. arabica n. sp. in one peacock. Sporulated oocysts of Eimeria riyadhae are ellipsoidal, 27-30.5 x 20.5-25 (28.8 +/- 1.3 x 22.4 +/- 1.6) micron, with a two-layered wall and bilobed polar body, but without a micropyle or residuum. The sporocysts are ov...
