Project description:This SuperSeries is composed of the following subset Series:; GSE15019: Transcriptome analysis of bovine mammary gland tissue treated with E. coli for 6 hours; GSE15020: Transcriptome analysis of bovine mammary gland tissue treated with E. coli for 24 hours; GSE15022: Transcriptome analysis of bovine mammary gland tissue of an udder quarter adjacent to an E.coli treated one for 24 hrs Experiment Overall Design: Refer to individual Series
Project description:Mastitis in dairy cattle can result from infection by a range of microorganisms but is principally caused by coliform bacteria and gram positive bacteria such as Staphylococcus aureus (S. aureus). The former species are often acquired by environmental contamination while S. aureus is particularly problematic due to its resistance to antibiotic treatments and ability to reside within mammary tissue in a chronic, subclinical state. The transcriptional and translational responses within bovine mammary epithelial tissue subjected to intramammary challenge with S. aureus are poorly characterised, particularly at the earliest stages of infection. A Bovine Innate Immune Microarray was employed to measure changes in gene expression occurring in bovine mammary tissues sampled from three dairy cows after a brief and graded intramammary challenge with a virulent strain of S. aureus. Keywords: dose response, disease state analysis
