Expression profiles in different stages of the immune response to Salmonella enterica Pullorum in the chicken spleen

ABSTRACT: Salmonella enterica Pullorum（S. Pullorum） is one of the most important pathogens in poultry. A better understanding of the immune response and molecular modulation resulting from infection by S. Pullorum will facilitates the control of this pathogen. In this study, we determined the relationships among identified differential expressed genes (DEGs) and pathways via deeply mining microarray data from Guangxi Huang Chicken challenged with S. Pullorum.

Expression profiles in different stages of the immune response to Salmonella enterica Pullorum in the chicken spleen

Project description:Salmonella enterica PullorumM-oM-<M-^HS. PullorumM-oM-<M-^I is one of the most important pathogens in poultry. A better understanding of the immune response and molecular modulation resulting from infection by S. Pullorum will facilitates the control of this pathogen. In this study, we determined the relationships among identified differential expressed genes (DEGs) and pathways via deeply mining microarray data from Guangxi Huang Chicken challenged with S. Pullorum. The chicks were then sacrificed via cervical dislocation immediately after anesthesia with 150 mg/kg sodium pentobarbital. This process was repeated at 2 hours post-infection (hpi), 4 hpi, 8 hpi, 24 hpi, 3 days post-infection (dpi), 5dpi, 7dpi, 12dpi, and 21dpi.The spleens were used to carrying out the microarray experiment. After total RNA extraction and quality control for each splenic sample were performed according to the standard protocol provided by Agilent Technologies, two random mRNA samples collected from the challenged group were equally mixed to hybridize with one chicken whole genome expression chip (Agilent.SingleColor.26441M-oM-<M-^I for each time point. In the challenged group, there were three biological replications (chips) for every time point. However, in the control group at each time point only one chip was used to hybridize with equally mixed mRNA sample containing the three control samples.

Transcriptomic analysis of attenuated Salmonella Typhimurium infected chicken primary macrophages

Project description:Salmonella enterica is one of the most important foodborne pathogens that infect a variety of animals and birds. In humans, S. Typhimurium causes gastroenteritis, leading to vomiting, diarrhea, fever, and abdominal cramps. We mainly get infected with Salmonella by ingesting comminated poultry products. Therefore, developing an oral live attenuated vaccine for the poultry industry is our best bet against Salmonella infection. In this article, we investigated the potential of the next generation of Salmonella vaccines. We generated a library of potentially attenuated S. Typhimurium mutants and compared fitness to that of a commercial vaccine. We also investigated the invasion and survival potential of these mutants in chicken macrophages. Our data indicate that although these mutants had no significant growth defects, they were much sensitive to macrophage attack. Analyzing the transcriptome data from infected primary chicken macrophages, we concluded that these mutants elicit a robust immune response by activating several immunoregulatory pathways. Our data also indicates that by combining phoPQ deletion with an already existing cya-crp deletion in MeganVac1, a much stronger immune response can be generated.

Transcriptomic profiling of antibiotic-resistant Salmonella Heidelberg in the presence of commensal Escherichia coli of poultry origin

Project description:The non-typhoidal Salmonella enterica serotype Heidelberg is a major foodborne pathogen primarily transmitted to humans through contaminated poultry products. Current control measures emphasize novel approaches to mitigate Salmonella Heidelberg colonization in poultry and the contamination of poultry products, thereby reducing its transmission to humans. This study highlight that commensal E. coli 47-1826 can potentially be used to control of S. Heidelberg 18-9079 in poultry

Dendritic cells infected with Salmonella enterica

Project description:Salmonella enterica causes serious global burden of morbidity and mortality and is a major cause of infant bacteremia in sub Saharan Africa. Diseases caused by Salmonella are treatable with antibiotics but successful antibiotic treatment has become difficult due to antimicrobial resistance. An effective vaccine together with public health effort may therefore be a better strategy to control these infections. Protective immunity against Salmonella depends primarily on T cell-mediated immune responses and therefore identifying relevant T cell antigens is necessary for Salmonella vaccine development. Our laboratory has used an immunoproteomics approach to identify Chlamydia T cell antigens that exhibited significant protection against Chlamydia infection in mice. In this study, we infected murine bone marrow derived dendritic cells from C57BL/6 mice with Salmonella enterica strain SL1344 followed by isolation of MHC class I and II- molecules and elution of bound peptides. The sequences of the peptides were then identified using tandem mass spectrometry. We identified 87 MHC class II and 23 MHC class I Salmonella derived peptides. Four of 12 peptides stimulated IFN-? production by CD4 T cells from the spleens of mice with persistent Salmonella infection. These antigens will be useful for Salmonella immunobiology research and are potential Salmonella vaccine candidates.

Gene expression responses to a Salmonella infection in the chicken intestine differ between lines.

Project description:Poultry products are an important source of Salmonella enterica. An effective way to reduce food poisoning due to Salmonella would be to breed chickens more resistant to Salmonella. Unfortunately resistance to Salmonella is a complex trait with many factors involved. To learn more about Salmonella resistance mechanisms in young chickens, a cDNA microarray analysis was performed to compare gene expression profiles between a Salmonella susceptible and a more resistant chicken line. Newly hatched chickens were orally infected with S. enterica serovar Enteritidis. Since the intestine is the first barrier the bacteria encountersbacteria encounter after oral inoculation, gene expression was investigated in the intestine, from day 1 until day 21 post infection. Differences in gene expression between the susceptible and resistant chicken line were found in control as well as Salmonella infected conditions. In response to the Salmonella infection, the expression of different sets of genes seemed to be affected in the jejunum of the two chicken lines. In the susceptible line this included genes that affect T-cell activation, whereas in the more resistant line, at day 1, macrophage activation seemed to be more affected. At day 7 and 9 most gene expression differences between the two chicken lines were identified under control conditions, indicating a difference in the intestinal development between the two chicken lines which might be linked to the difference in Salmonella susceptibility. The findings in this study have lead to the identification of novel genes and possible cellular pathways of the host involved in Salmonella susceptibility. Keywords: timecourse, disease
