Dermatology section: ⱡ Number of isolates tested: Staphylococcus spp. = 29. ** Number of isolates tested for cephalothin susceptibility were as follows: Staphylococcus spp. = 26, Streptococcus spp. = 11. * Number of Staphylococcus spp. isolates tested for penicillin and ticarcillin susceptibility was 29. Surgery section: * Number of Staphylococcus spp. isolates tested for ampicillin; penicillin and ticarcillin susceptibility was 16. ** Number of isolates tested for cephalothin susceptibility was 10. Oncology section: ** Numbers of isolates tested for cephalothin susceptibility were as follows: Staphylococcus spp. = 20, Streptococcus spp. = 19. * Number of Staphylococcus spp. isolates for penicillin and ticarcillin susceptibility was 25. Grey-shading indicates that susceptibility to a drug was not tested with that organism.
