ABSTRACT: Mycobacterium orygis and Mycobacterium tuberculosis sensu stricto but not Mycobacterium bovis are recovered from cattle at a slaughterhouse in Chennai, India
Project description:Whole RNA transcriptome was performed on bovine lung granulomatous tissues from Mycobacterium orygis infected cattle and compared with healthy cattle lung tissues.
Project description:Mycobacterium bovis (M. bovis) and Mycobacterium avium subspecies paratuberculosis (MAP) are important pathogens of cattle, causing bovine tuberculosis and Johne’s disease respectively. M. bovis and MAP infect residential macrophages in the lung and intestines respectively and subvert the macrophage biology to create a survival niche. To investigate this interaction we simultaneously studied the transcriptional response of bovine monocyte-derived macrophages to infection with two strains of M. bovis (AF2122/97 and G18) and two strains of MAP (C & L1).
Project description:This comparative transcriptomic study examines the differences in the gene expression profile in PBMCs from indigenous Sahiwal and Crossbred (Sahiwal x Holstein Friesian) cattle in response to Infection with virulent Mycobacterium tuberculosis and vaccine stain M. bovis BCG.
Project description:The similarity of Lyme borreliosis to other diseases and the complex pathogenesis cause diagnostic and therapeutic difficulties. Changes at the cellular and molecular level after Borrelia sp. infection remain still poorly understood. Therefore, the present study focused on the gene expression in human dermal fibroblasts in differentiation of infection with Borrelia garinii, Borrelia afzelii and Borrelia burgdorferi sensu stricto spirochetes. For microarray analysis 10 samples were used: 3 control samples - K, 2 samples of NHDF cells infected with Borrelia garinii - G, 2 samples of NHDF cells infected with Borrelia afzelii - A and 3 samples of NHDF cells infected with Borrelia burgdorferi sensu stricto - SS.
