Fig 1. Preliminary experiment to determine the doses of LPS and ovalbumin suitable for induction of synergistic mammary inflammation.

A) Schematic representation of the udder with its four quarters and the challenge intramammary infusion. Three cows previously sensitized to ovalbumin received either 0.2 μg LPS, 0.5 or 1 μg ovalbumin, or 0.2 μg LPS and 0.5 μg ovalbumin in combination into one quarter to trigger inflammation. B) Concentrations of milk cells (somatic cell count) in milk of the infused quarters as a function of time post-infusion.
