ABSTRACTThis study describes a novel immunization strategy against avian coccidiosis using exosomes derived fromEimeriaparasite antigen (Ag)-loaded dendritic cells (DCs). Chicken intestinal DCs were isolated and pulsedin vitrowith a mixture of sporozoite-extracted Ags fromEimeria tenella,E. maxima, andE. acervulina, and the cell-derived exosomes were isolated. Chickens were nonimmunized or immunized intramuscularly with exosomes and subsequently noninfected or coinfected withE. tenella,E. maxima, andE. acervulinaoocysts.

Abstract:

Eimeria tenella (E. tenella) is a highly pathogenic and prevalent species of Eimeria that infects chickens, and it causes a considerable disease burden worldwide. The secreted proteins and surface antigens of E. tenella at the sporozoite stage play an essential role in the host–parasite interaction, which involves attachment and invasion, and these interactions are considered vaccine candidates based on the strategy of cutting off the invasion pathway to interrupt infection. We selected two highly expressed surface antigens (SAGs; Et-SAG13 and Et-SAG) and two highly expressed secreted antigens

Abstract:

ABSTRACT The recent cloning of chicken genes coding for interleukins, chemokines, and other proteins involved in immune regulation and inflammation allowed us to analyze their expression during infection with Eimeria. The expression levels of different genes in jejunal and cecal RNA extracts isolated from uninfected chickens and chickens infected with Eimeria maxima or E. tenella were measured using a precise quantitative reverse transcription-PCR technique. Seven days after E. tenellainfection, expression of the proinflammatory cytokine interleukin-1β (IL-1β) mRNA was increased 80-fold. Among

Evidence exists that lethal activity is associated with extracts from Eimeria tenella-infected caecal tissues. We examined tissues of the small intestine infected with other species of Eimeria for a similar lethal activity.

Appropriate control extracts from tissues of non-infected chickens were also prepared. Intravenous injection of the extracts into healthy chickens showed that lethality of infected tissue extracts was higher than control extracts an

Coccidia-free chickens were orally inoculated with mixed oocysts of the two strains and parasites of the F1 generation were recovered. The F1 progeny showed both forms of the isozyme.

The EtMIC2 gene, which codes for a 35.07 kDa protein in E. tenella sporulated oocysts, was cloned and recombinant EtMIC2 protein (rEtMIC2) was produced in an Escherichia coli expression system.

Abstract:

Eimeria tenella is an obligate intracellular parasite that actively invades cecal epithelial cells of chickens. When E. tenella infects a host cell, the host produces a corresponding change to deal with damage caused by this infection. To date, our knowledge on the mechanism of how the host cell responds to E. tenella infection is highly limited at both the molecular and cellular levels. In this study, isobaric tags for relative and absolute quantitation (iTRAQ) coupled with LC-MS/MS was used to screen the differentially expressed proteins (DEPs) in BHK-21 cells infected with E. tenella sporoz

Abstract:

ABSTRACT Recombinant attenuated Salmonella vaccines against avian coccidiosis were developed to deliver Eimeria species antigens to the lymphoid tissues of chickens via the type 3 secretion system (T3SS) and the type 2 secretion system (T2SS) of Salmonella. For antigen delivery via the T3SS, the Eimeria tenella gene encoding sporozoite antigen SO7 was cloned downstream of the translocation domain of the Salmonella enterica serovar Typhimurium sopE gene in the parental pYA3868 and pYA3870 vectors to generate pYA4156 and pYA4157. Newly constructed T3SS vectors were introduced into host strain χ8

Abstract:

AbstractMixed infections of Toxoplasma gondii and Eimeria tenella are likely to occur frequently due to the high prevalence of both pathogens in free-ranging chickens. In this study, we investigated the co-occurrence of the two parasites in the same immune-competent host cell towards altered patterns of parasite-host interactions. Chicken blood monocyte–derived macrophages were co-infected with T. gondii RH tachyzoites and E. tenella Houghton sporozoites in vitro for 24 h. Through monitoring the uptake of pH-sensitive pHrodo™ Zymosan BioParticles (“Zymosan”) by macrophages, we created a three-

Abstract:

Avian coccidiosis，caused by parasites of the genus Eimeria, is a major intestinal disease of chickens. In order to develop a new generation of vaccine which can provide a safer, more effective and cost-effective approach for avian coccidiosis control, bioinformatic and molecular approaches are used to predict and analyze the molecular characterization and B-cell epitopes of Eimeria antigens. In the present study, the molecular characterization and B-cell epitopes of the antigen pEtK2 of Eimeria tenella（E.tenella）were predicted by using of bioinformatics techniques. The pEtK2 gene was predicted

Abstract:

Interleukin 6 (IL-6) is an immunoregulatory cytokine involved in various inflammatory and immune responses. To investigate the effects of single nucleotide polymorphisms (SNPs) and haplotypes of IL-6 on resistance to Eimeria tenella (E. tenella), SNPs in the 5′ regulatory region of IL-6 were detected with direct sequencing, and the effects of SNPs and haplotypes on resistance to E. tenella were analyzed by the least square model in Jinghai yellow chickens. Nineteen SNPs were identified in the 5′ regulation region of IL-6, among which three SNPs were newly discovered. The SNP association analys
