Some observations on the adaptation of Eimeria tenella (local isolates) sporozoites on chicken embryos through chorioallantoic membrane
Eimeria (E.) tenella (local isolate) sporozoites were adapted on the chorioallantoic membrane (CAM) of 10-12 days chicken embryos and completed its life cycle in 6-7 days at 39 degrees C and 70 per cent humidity. Only 23 embryos (4.6%) were found dead from 1-4 day post inoculation of sporozoites with mild lesions on CAM with no gametocytes but few sporozoites in chorioallantoic fluid (CAF). On ...
متن کاملCharacterization of the antigen SO7 during development of Eimeria tenella.
The developmental expression of the antigen SO7, which has been previously shown to protect chickens against infection by several Eimeria species, was investigated. Using RT-PCR, mRNA for SO7 was found to be restricted primarily to unsporulated oocysts (0 hr). Western blot (WB) analysis with an antibody to recombinant SO7 (rbSO7) revealed expression of the protein from 6 to 72 hr (fully sporula...
متن کاملCoccidian merozoite transcriptome analysis from Eimeria maxima in comparison to Eimeria tenella and Eimeria acervulina.
With the Eimeria spp. populations that infect chickens used as a model for coccidian biology, we aimed to survey the transcriptome of Eimeria maxima and contrast it to the 2 other Eimeria spp. for which transcriptome data are available, i.e., Eimeria tenella and Eimeria acervulina . The asexual intracellular development stage, the merozoite, was specifically examined, and we used expressed sequ...
متن کاملPartial purification and characterization of an aminopeptidase from Eimeria tenella.
Our previous investigation demonstrated the expression in Eimeria tenella sporulated oocysts of an aminopeptidase (AP) with strong homology to AP N. To further understand the role of proteases during development, we investigated the molecular and biochemical properties of E. tenella AP. Greater than 95% AP activity was present in a soluble extract during sporulation of oocysts with highest acti...
متن کاملSuppression of Eimeria tenella Sporulation by Disinfectants
The disinfectant effects (DEs) of 10 types of chemicals, defined by their ability to destroy or inhibit oocysts and consequently prevent sporulation of Eimeria tenella field isolate, were evaluated in vitro. Correct species assignments and sample purities were confirmed by the singular internal transcribed spacer (ITS)-PCR analysis. A total of 18 treatments were performed, and the disinfection ...
