Effect of experimental infection with Escherichia coli (0 h) and intramammary treatment with ceftiofur hydrochloride (48, 72, 96, 120, and 144 h) on relative abundance of Enterobacteriaceae. Effect of challenge and treatment (a, N = 24 quarters), effect of intramammary challenge with Escherichia coli (b, N = 24) and stratified analysis of covariance assessing the effect of intramammary treatment with ceftiofur hydrochloride in challenged (c, N = 8) and unchallenged quarters (d, N = 16). Asterisks represent differences after Tukey-Kramer multiple comparison correction and α = 0.05 between groups within the same time point. Black diamonds represent experimental infection with 100 CFU of E. coli, and grey circles represent intramammary treatment with ceftiofur
