Proteomics data of ovine mastitis associated with Mannheimia haemolytica

Abstract

Proteomics data have been obtained from experimental mastitis in ewes after intramammary challenge with Mannheimia haemolytica. Animals were sampled before and sequentially after challenge; blood plasma and milk whey samples were produced and were subjected to proteomics evaluation by means of two-dimensional gel electrophoresis and MALDI-TOF mass spectrometry. Full protein maps and differential proteomics in sequential samples from blood plasma and milk whey of experimental ewes were presented. Post-challenge, 33 and 89 proteins were identified with differential abundance in blood plasma and milk whey, respectively. Also, 74 proteins were identified with differential abundance between the inoculated and contralateral glands. The data provide further insight in the pathogenesis of mastitis in sheep and indicate potential biomarkers for the disease. The data are further discussed in the research article “Differential quantitative proteomics study of experimental Mannheimia haemolytica mastitis in sheep” [1].
