Haemophilus parasuis is the etiological agent of Glasser’s disease in pigs. We used microarrays to study the transcriptome of PAMs infection with HPS4.
Project description:Haemophilus parasuis(HPS) is a prominent swine pathogen that causes Glässer's disease characterized by fibrinous polyserositis, meningitis and arthritis; however, the molecular mechanisms underlying disease pathogenesis remains poorly understood, particularly the host counteraction to HPS invasion by the immune system. Here, we investigated the global expression changes in spleen following HPS infection using the Affymetrix Porcine Genechip.Our findings indicate previously unrecognized gene transcription changes in case of HPS infection in vivo and many presumed cascades in the study are clearly merit further investigation. Our data should provide new clues for immune response in mammals and identification of candidate genes related to HPS resistance.
Project description:Porcine alveolar macrophages (PAMs) play impoartant role in innate immunity. Haemophilus parasuis is the etiological agent of Glasser’s disease in pigs. We used microarrays to study the transcriptome of PAMs infection with Haemophilus parasuis. Healthy Pigs were intratracheally challenged with H.parasuis strain 0165. And the PAMs were isolated at 6 dpi. RNA extraction were extracted from PAMs that obtained from infection pigs and control pigs and hybridization on Affymetrix microarrays. We sought to obtain the differently expressed genes that related to H.parasuis infection to understand the mechanism of PAMs against H.parasuis.

Haemophilus parasuis is the etiological agent of Glasser’s disease in pigs. We used microarrays to study the transcriptome of PAMs infection with HPS4. Healthy Pigs were inoculated intranasally with 2 ml of 4.5×108CFU/ml colony forming units of HPS4 strain MD0322. And the PAMs were isolated at 28 dpi. RNA extraction were extracted from PAMs that obtained from infection pigs and control pigs and hybridization on Affymetrix microarrays.

Project description:Haemophilus parasuis(HPS) is a prominent swine pathogen that causes GlM-CM-$sser's disease characterized by fibrinous polyserositis, meningitis and arthritis; however, the molecular mechanisms underlying disease pathogenesis remains poorly understood, particularly the host counteraction to HPS invasion by the immune system. Here, we investigated the global expression changes in spleen following HPS infection using the Affymetrix Porcine Genechip.Our findings indicate previously unrecognized gene transcription changes in case of HPS infection in vivo and many presumed cascades in the study are clearly merit further investigation. Our data should provide new clues for immune response in mammals and identification of candidate genes related to HPS resistance. All animal tissue collection procedures were performed according to protocols approved by The Hubei Province, PR China for Biological Studies Animal Care and Use Committee. Piglets at 30 days old were determined to be HPS-free by serum indirect haemagglutination test before artificial bacterial challenges. Each piglet was intratracheally challenged with 5M-CM-^W108 colony-forming units (CFU) per millilitre of HPS strain 0165 (serotype 5) . A total of 5 piglets were challenged, and 5 pigs were used as controls. These two groups were raised in isolated facilities. Six microarrays were used in the experiment, corresponding to the RNAs from spleen tissues of three most severe piglets with fibrinous polyserositis, meningitis and arthritis after HPS infection and three controls.
