Rapidity of most severe local disease. Scatterplot showing the number of days it took for chinchillas inoculated with the 10 clinical NTHi strains to develop their maximum (most severe) otologic score – regardless of what that score was. X-axis = the clinical NTHi strains (PittAA-PittJJ, left to right); Y-axis = the days post inoculation that moderate or worse local disease developed.
