PreimmuneO7O116O157
O7:NM75.09.08.43.8
O116:NM67.58.759.55.5
O157:H770.56.28.78.7
O157:H1970.512.746.67.7
  • a The values are for the last serum dilution showing bacterial activity with a statistically significant difference (P < 0.05) when the results obtained were compared with those observed with preimmune serum.
