Comparative Transcriptome Analyses of Drug-sensitive and Drug-resistant Strains of Eimeria tenella by RNA-sequencing

ABSTRACT: To gain insights into the molecular mechnism governing the drug resistance of Eimeria tenella, two drug-resistant strains of E. tenella, maduramicin-resistant (MRR) strain and diclazuril-resistant (DZR) strain were induced.We carried out comparative transcriptome analyses of a drug-sensitive strain (DS) and two drug-resistant strains (MRR and DZR) of E. tenella by RNA-seqencing. A total of 1070 DEGs, 672 upregulated and 398 downregulated, were identified in MRR vs. DS; and 379 DEGs, 330 upregulated and 49 downregulated, were detected in DZR vs. DS. Functional annotation analysis identified several DEGs coding for proteins associated with catalytic activity in the DZR strain that were involved in glycolysis and the tricarboxylic acid (TCA) cycle. Other DEGs were associated with ion binding and ion transmembrane transporter activity in the MRR strain. Some DEGs coded for surface antigens that were downregulated in two drug-resistant strains involved invasion, pathogenesis, and host–parasite interactions.These results contribute to developing rapid molecular methods to detect drug resistance of Eimeria spp. in poultry.

Dual RNA-seq transcriptome analysis of chicken caeca infected with Eimeria tenella

Project description:In order to elucidate the infection mechanisms of Eimeria tenella and the chicken immune response, chickens were infected with Eimeria tenella strain Hougton sporozoites. Samples were taken at 0, 1, 2, 3, 4 and 10 days post-infection and mRNA sequenced. A dual-RNA seq analysis was carried out, comparing the expression of infected chickens during each sampling time point with uninfected chickens and comparing E. tenella samples during the infection with a sample of pure sporozoites. The results show a variety of response signals in the chicken, both previously known and unknown, as well as a clear role for a variety of infection-related genes in E. tenella

Dual RNA-seq transcriptome analysis of chicken macrophage-like cells (HD11) infected in vitro with Eimeria tenella

Project description:In order to elucidate the infection mechanisms of Eimeria tenella and the chicken immune response, chicken macrophage cell cultures of cell line HD-11 were infected with Eimeria tenella strain Hougton sporozoites. Samples were taken at 0, 2, 4, 12, 24, 48 and 72 hours post-infection and, purified and mRNA sequenced. A dual-RNA seq analysis was carried out, comparing the expression of infected chicken macrophages with uninfected ones at the same time points post-infection and comparing E. tenella samples during the infection with a sample of pure sporozoites. The results show a variety of response signals in the chicken, both previously known and unknown, as well as a clear role for different sets of SAG and MIC proteins for sporozoites and merozoites of E. tenella

RNA-Seq of E.tenella Houghton life cycle stages

Project description:Recent advances in high throughput sequencing methodologies allow the opportunity to probe in depth the transcriptomes of organisms including E. tenella. In this project, we are using Illumina sequencing technology to analyze the transcriptome (RNA-Seq) of experimentally accessible stages (e.g. sporozoites, merozoites, unsporulated oocysts, sporulated oocysts) of E. tenella Houghton. The aim is to make transcriptional landscape maps of different life cycle stages of E. tenella at single base pairs resolution and utilise this information to identify the genes and define the precise gene boundaries. Gene finding has been a rather difficult task in Eimeria. Obtaining the precise transcript boundaries by Illumina RNA-Seq protocol is expected to expedite gene finding in Eimeria tenella. This data is part of a pre-publication release.

Comparative analysis of Gallus gallus cecal epithelia following Eimeria tenella infection

Project description:Relative expression levels of mRNAs in chicken cecal epithelia experimentally infected with Eimeria tenella were measured at 4.5 days post-infection. Two weeks old chickens were uninfected (negative control) or were orally inoculated with sporulated oocysts of Eimeria tenella. Cecal epithelia samples were collected from >12 birds in infected or uninfected group at 4.5 d following infections, in which samples from 4 birds were pooled together to form a total 3 biological replicates in each group. Parasite merozoites were also collected from four infected chickens at 5 d after infections. Uninfected control samples, merozoites and infection group samples were selected for RNA extraction and hybridization on Affymetrix microarrays. We used Affymetrix GeneChip chicken genome arrays to detail the chicken cecal epithelia gene expression in the control and E. tenella-infected birds. Infected, uninfected chicken cecal epithelia and merozoites were selected for RNA extraction and hybridization with Affymetrix microarrays. Our goal was to analyze global transcriptome changes in chicken cecal mucous membranes in response to E. tenella infection in vivo. We used infected (T1,T2,T3; three biological replicates) and uninfected (Neg1, Neg2, Neg3; three biological replicates) samples to identify genes that were differentially expressed. Meanwhile, RNA and probes were also prepared from parasite merozoites (Mzt) from infected samples (Mzt) and used as an additional control in microarray hybridization.

Gene expression profile of wild-type and isoniazid resistant strains of Mycobacterium smegmatis

Project description:Understanding emergence of drug resistance in pathogens systematically is a major challenge. To address this issue, lab-evolved strain resistant to first-line tuberculosis drug, isoniazid (INH), was analysed. Transcriptome analysis of different conditions revealed genes that are differentially regulated in wild-type (WT) and isoniazid resistant (2XR and 4XR) strains. Microarray analysis was performed for WT, sub-MIC, 2XR and 4XR strains of Mycobacterium smegmatis. Overall, the numbers of DEGs observed are 1529 in sub-MIC (596 - up, 933 - down), 1381 (899 – up, 482 – down) in 2XR and 716 in 4XR (267 – up, 449 – down) conditions. 52 of them are seen to be up-regulated across all drug concentrations as compared to WT while 185 are seen to be down-regulated in all. Transcriptome analysis revealed that there are variations in gene expression pattern in the resistant strains as compared to WT strain. This indicates that differential regulation of genes is, in some way, responsible for conferring the phenotype to the organism.

Transcriptome Analysis Revealed Ameliorative Effects of Bacillus Based Probiotic on Immunity and Metabolism under an Experimentally Induced Eimeria tenella Infection in Chicken

Project description:In order to explore the potential therapeutic mechanisms of Bacillus subtilis (B. subtilis) probiotic under Eimeria tenella (E. tenella) infection, we performed Transcriptome analysis. A total of 63 Chinese native yellow chickens were purchased from a commercial hatchery and reared in 9 coccidia-free cages with free access to feed and water for up to 28 days. Upon arrival, all chicks were weighed and randomly divided into one of three experimental groups with 21 birds in each group. The three groups consisted of negative control untreated non-challenged group (NC), positive control untreated challenged group (PC) and B. subtilis-fed challenged group (BS + ET). Challenged and non-challenged groups were housed in two different rooms for avoiding the transmission of disease. Temperature (32 to 34 °C for 1st week and then decreased by 2 °C per week), humidity (60 to 80%) and light (23 h L:1D) of both rooms were maintained during the entire period of experiment. On day 21 of age, the chickens in group PC and BS + ET were challenged with 6 × 10^4 E. tenella sporulated oocysts, whereas the chickens in group NC were gavaged with normal saline to provide same management stress. On day 28 of age (day 7 post-infection), 3 individual chickens per group were euthanized humanely by direct heart puncture and caecum tissue samples of all groups were collected for analyzing the whole transcriptional responses to the exposure of probiotic under an induced E. tenella infection in chickens. Totally, 1902 DEGs were up-regulated and 1589 DEGs were down-regulated in the positive control group versus negative control group. 341 up-regulated and 124 down-regulated DEGs were found in the comparison of BS + ET group versus NC Group, while 784 up-regulated and 493 down-regulated DEGs were found in BS + ET versus PC group.
