Popis: | The aim of this study was to characterize the immune response in Staphylococcus aureus chronicallyinfected bovine mammary glands during active involution. Twenty-one Holstein non-pregnant cows inlate lactation either uninfected or with chronic naturally acquired S. aureus intramammary infections(IMI) were included in this study. Cows were slaughtered at 7, 14 and 21 d after cessation of milkingand samples for immunohistochemical analysis were taken. Protein expression of toll-like receptor 2(TLR2) and TLR4 was significantly higher in S. aureus-infected quarters than in uninfected controls atthe three involution stages studied. Protein expression of tumor necrosis factor-alpha (TNF-á),interleukin (IL)-1á and IL-17 was significantly affected by IMI; being higher in S. aureus-infectedthan uninfected quarters during all evaluated stages. In S. aureus-infected and uninfected quartersprotein expression of lactoferrin increased from day 7 to 14 of involution, decreasing significantly today 21 in mammary quarters with chronic infections. The number of monocytes-macrophages wassignificantly higher in S. aureus-infected than in uninfected control quarters at 7 and 21 d ofinvolution. The number of T lymphocytes was significantly higher in S. aureus-infected than inuninfected quarters at 7 and 14 d of involution while the number of B lymphocytes was significantlyhigher in S. aureus-infected than in uninfected quarters during all evaluated stages, showing aprogressive increase as involution advanced. These results demonstrated a sustained and exacerbatedinnate and adaptive immune response during chronic S. aureus IMI, playing a critical role in theinfection control during active involution Fil: Andreotti, Carolina Soledad.
