Intestinal proteomic response to oral challenge of enterotoxigenic Escherichia coli in weaned pigs

ABSTRACT: Enterotoxigenic Escherichia coli (ETEC) is a major cause of diarrhoea in children in resource-limited countries and of travellers diarrhoea. The ileal proteomics change after ETEC challenge is less characterised. Here in this study changes of ileal proteins post ETEC challenge in weaned pigs are studied. In total, 5151 ileal proteins were successfully annotated and 9 proteins had significantly different abundance between the ETEC and CON pigs.

Enterotoxigenic Escherichia coli (ETEC) is closely associated with diarrhoea in children in resource-limited countries. This study aims to investigate the change of the mucosal microbiome and protein expression in the ileum induced by E. coli K88 (ETEC) using pigs as a model. Seven weaned male pigs were orally given ETEC (1 × 109 CFU, n = 7), and the other seven received saline (CON, n = 7). Ileal tissues were obtained 48 hours after the ETEC challenge for ...[more]

Transcription profiling of piglet ileal tissues to assess the impact of environment on microbial diversity and global transcriptional responses in the developing gut

Project description:The study investigated the impact of environment on the composition of the gut microbiota and mucosal immune development and function at gut surfaces in early and adult life. Piglets of similar genotype were reared in indoor and outdoor environments and in an experimental isolator facility. Mucosa-adherent microbial diversity in the pig ileum was characterized by sequence analysis of 16S rRNA gene libraries. Host-specific gene responses in gut ileal tissues to differences in microbial composition were investigated using Affymetrix microarray technology and Real-time PCR. Experiment Overall Design: Animals were reared on the sow at an outdoor or indoor facility. Additional piglets from the indoor facility were transferred to individual isolator units at 24 hours of age, and given a daily dose of antibiotic cocktail for the duration of the study. Piglets were weaned at day 28. From day 29 onwards, piglets were fed creep feed ad libitum. Ileal tissue samples were excised from N=6 piglets per group at day 5, 28 and 56.

Comparative trancriptome analysis of weaned pigs in response to different dietary starch sources

Project description:The starch, acting as the major energy-producing component of the daily diet, is the main carbohydrate in mammal nutrition. However, the nutritional value of starch can vary widely depending upon its source and site of digestion. The distinct physiological responses were previously observed both in human and other mammals, but still little is known about the underlying mechanisms regarding the metabolic shifts due to the intake of various dietary starches. Here, we assessed the overall metabolic changes in weaned pigs induced by different dietary starch sources at the transcriptome level. Sixteen weaned pigs (DurocÃLandraceÃYorkshire) were selected and randomly allotted to diets containing either wheat (WH) or cassava (CA) starch as the energy source (n=8). We measured serum metabolites and hormones and generated transcriptional profiles of liver. 648 genes in liver were differentially expressed in response to dietary starch sources. Pathway analysis indicated that dietary starch sources altered both carbohydrate and lipid metabolism in liver. In contrast, CA may be more healthful as dietary energy source than WH by down-regulating lipogenesis and steroidogenesis in liver. Sixteen weaned pigs (DurocÃLandraceÃYorkshire) with an average initial body weight of 7.37Â±0.25 kg were selected and randomly allotted to two dietary treatments (either wheat or cassava starch as the energy source) for 21 d. At the end of the trial, the liver tissue were collected for transcriptome analysis using Agilent porcine microarrays.

Integrated transcriptomics and proteomics analysis reveals muscle metabolism effects of dietary Ulva lactuca and ulvan lyase supplementation in weaned piglets

Project description:Seaweeds, including the green Ulva lactuca, can potentially reduce competition between feed, food, and fuel. They can also contribute to the improved development of weaned piglets. However, their indigestible polysaccharides of the cell wall pose a challenge. This can be addressed through carbohydrase supplementation, such as the recombinant ulvan lyase. The objective of our study was to assess the muscle metabolism of weaned piglets fed with 7% U. lactuca and 0.01% ulvan lyase supplementation, using an integrated transcriptomics (RNA-seq) and proteomics (LC-MS) approach.

Suckling piglets: Control vs. weaned piglets

Project description:Transcriptional profiling of 25d old piglets comparing control untreated suckling jejunum with weaned piglets' jejunum. The goal was to gain new insight into the interaction between weaning and intestinal function.A keen interest is paid in deciphering expression changes of apoptosis or cell cycle control genes. The statistical analysis of gene ontology revealed that most of these altered genes are metabolic-related enzymes and regulators which may involved in the biological regulation, developmental process, and cellular process. Weaning also causes alterations in various immune response pathways. Results likely indicate that weaning induced cell cycle arrest, enhanced apoptosis, and inhibited cell proliferation. Two-condition experiment, suckling control piglets' jejunum vs. weaned piglets' jejunum. Biological replicates: 4 control replicates, 4 weaned replicates.

Use of an ETEC proteome microarray to evaluate cross-reactivity of ETVAX® vaccine-induced IgG antibodies in Zambian children

Project description:Enterotoxigenic E. coli (ETEC) is a major cause of moderate to severe diarrhoea in low-middle income countries (LMICs) and affects mostly children and travelers to endemic regions. ETEC are highly diverse pathovar with over 25 colonisation factors (fimbriae) described. The development of a broadly protective vaccine to cover most of the ETEC variants is critical for disease control. This study evaluated whether vaccination with ETVAX®; the most clinically advanced ETEC vaccine candidate results in IgG responses that cross-react with other ETEC antigens/ colonisation factors not overexpressed in the vaccine. A proteome microarray was used to assess IgG responses before and after vaccination to gain insight in the antigenic composition of ETEC that children in Zambia are exposed to and to see whether ETVAX® provides a level of cross-protection against antigens not expressed in the vaccine. The study shows that ETVAX® containing CFA/1, elicits antibodies that cross-react with other class 5 fimbriae and has the potential to offer broad protection. We also see that other antigens apart from classical antigens are immunodominant and possibly play a role in ETEC pathogenesis and may need to be investigated for their role in protection

Molecular and immunological interrogation of a live-attenuated enterotoxigenic Escherichia coli vaccine highlights features unique to wild type infection

Project description:Enterotoxigenic Escherichia coli (ETEC) infections are a common cause of diarrheal illness in low- and middle-income countries. The live-attenuated ACE527 vaccine, adjuvanted with double mutant LT (dmLT), affords clear but partial protection against ETEC challenge inhuman volunteers. Comparatively, initial wild-type ETEC challenge completely protects against severe diarrhea on homologous re-challenge...To investigate molecular determinants of protection, vaccine antigen content was compared to wild-type ETEC, and proteome microarrays were used to assess immune responses following vaccination and ETEC challenge... Although molecular interrogation of the vaccine confirmed expression of targeted canonical antigens, relative to wild-type ETEC, vaccine strains were deficient in production of flagellar antigens, immotile, and lacked production of the EtpA adhesin. Similarly, vaccination ± dmLT elicited responses to targeted canonical antigens, but relative to wild-type challenge, vaccine responses to some potentially protective non-canonical antigens including EtpA were diminished or absent...These studies highlight important differences in vaccine and wild-type ETEC antigen content and call attention to distinct immunologic signatures that could inform investigation of correlates of protection, and guide vaccine antigen selection for these pathogens of global importance.

Proteomics of Diverse Clonal Groups of Enterotoxigenic Escherichia coli Underline Variations in Surface Antigens and Similarities in Metabolism

Project description:Enterotoxigenic Escherichia coli (ETEC) is an important cause of diarrhoea, a pervasive disease in low- and middle-income countries that affects mostly young children and visiting travellers. Substantial diversity exists among ETEC isolates, hindering development of effective preventive means. To investigate how ETEC genomic variation is reflected at expressed proteome level, we applied label-free quantitative proteomics to 7 human ETEC strains representing 5 epidemiologically important lineages. We further determined the protein profile of the non-pathogenic E. coli B strain BL21 to discriminate metabolic features specific for ETEC. The analysis yielded a dataset of 2,894 proteins, of which 1,777 were present in all strains. Each ETEC strain displayed on average 27 (±10) proteins with known or putative links to virulence, both plasmid- and chromosomally-encoded, and a number of strain-specific isoforms participating in the biosynthesis of surface antigens. Statistical comparison of relative protein levels between the ETEC strains and BL21 revealed several proteins with significantly increased amounts only in BL21, including enzymes of arginine biosynthesis and metabolism of melibiose, galactitol and gluconate. ETEC strains displayed consistently increased levels of proteins that were functional in iron acquisition, maltose metabolism, and acid resistance. These results suggest that specific metabolic functions are shared among ETEC isolates.
