Ex vivo phagocytosis (% killing) in milk samples taken at 18 hpi. Milk samples were incubated with gentle agitation at 37 °C, and % killing was calculated with reference to samples incubated at rest. Total milk CFU: the sum of in vivo grown bacteria in the sample plus 106 in vitro grown bacteria. SCC 18 hpi: SCC in the 18 hpi milk samples. Milk CFU 23 hpi: concentration of viable bacteria in the samples taken 5 h after the samples under phagocytic test. Colors correspond to increasing values from green to red.
