a Sampling day; b days post-inoculation; c inoculated steers; d contact steers; e average number of infectious steers during the time interval before sampling. New cases were assumed to be infectious in between the time interval; f number of susceptible steers at the beginning of the time interval prior to sampling; g number of new cases per time interval; h number of intermittent non-shedding steers at the beginning of the time interval preceding sampling; i time interval between two samplings; j strain of ECO157; k number of ECO157 in the environmental sample during the preceding sampling time in log10 scale.
