Ear samples: * Number of Staphylococcus spp. isolates for ampicillin, penicillin and ticarcillin susceptibility was 14. ** Number of Staphylococcus spp. isolates for cephalothin susceptibility was 17. Skin samples: * Number of Staphylococcus spp. isolates for ampicillin, penicillin and ticarcillin susceptibility was 31. ** Number of Staphylococcus spp. isolates for cephalothin susceptibility was 26. Grey-shading indicates that susceptibility to a drug was not tested with that organism.
