Inhibition of Eimeria acervulina Sporozoite Invasion by Rabbit and Chicken Antisera Using ISI Assay

Analysis of chicken cytokine and chemokine gene expression following Eimeria acervulina and Eimeria tenella infections.

The expression levels of mRNA encoding a panel of 28 chicken cytokines and chemokines were quantified in intestinal lymphocytes following Eimeria acervulina and Eimeria tenella primary and secondary infections. Compared with uninfected controls, transcripts of the pro-inflammatory cytokines IFN-alpha, IL-1beta, IL-6, and IL-17 were increased up to 2020-fold following primary infection. By contr...

Characterization of stage-specific and cross-reactive antigens from Eimeria acervulina by chicken monoclonal antibodies.

The characterization of five chicken monoclonal antibodies (mAbs) that were developed against apical complex antigens of Eimeria acervulina sporozoites is realized and the mAbs reactivity to merozoites belonging to this species is tested. Using immuno-fluorescence assay (IFA), one mAb (HE-4) that recognized apical antigens common to sporozoites of E. acervulina and E. brunetti bound antigens lo...

Identification of common immunodominant antigens of Eimeria tenella, Eimeria acervulina and Eimeria maxima by immunoproteomic analysis

Clinical chicken coccidiosis is mostly caused by simultaneous infection of several Eimeria species, and host immunity against Eimeria is species-specific. It is urgent to identify common immunodominant antigen of Eimeria for developing multivalent anticoccidial vaccines. In this study, sporozoite proteins of Eimeria tenella, Eimeria acervulina and Eimeria maxima were analyzed by two-dimensional...

The Inhibition of Streptococcal Desoxyribonuclease by Rabbit and Human Antisera

Rabbit antisera against partially purified streptococcal desoxyribonuclease inhibit the action of the enzyme on its substrate. The activity of pancreatic desoxyribonuclease is not affected by these antisera. Similarly antibody against pancreatic nuclease does not inhibit the streptococcal enzyme. Certain patients develop inhibitory antibody to streptococcal desoxyribonuclease following streptoc...

Analysis of global transcriptional responses of chicken following primary and secondary Eimeria acervulina infections

BACKGROUND Characterization of host transcriptional responses during coccidia infections can provide new clues for the development of alternative disease control strategies against these complex protozoan pathogens. METHODS In the current study, we compared chicken duodenal transcriptome profiles following primary and secondary infections with Eimeria acervulina using a 9.6K avian intestinal ...
