Gram-negatives: ** Numbers of isolates tested for cephalothin susceptibility were as follows: E. coli = 50, Proteus mirabilis = 12. ¥ indicates the drug is primarily used for Gram-positive organisms. Gram-positives: ** Numbers of isolates tested for cephalothin susceptibility were as follows: Staphylococcus spp. = 29, Streptococcus spp. = 24. * Number of Staphylococcus spp. isolates for penicillin and ticarcillin susceptibility was 35. Grey-shading indicates that susceptibility to a drug was not tested with that organism.
