This chapter includes the susceptibility of the bacteria most likely to be isolated from specific clinical entities, primarily of dogs and cats. The final calculation takes into account the relative frequency that each microorganism was isolated from the clinical entity. While the following tables are not meant to replace susceptibility tests, they should provide a guide for the choice of a drug most likely to successfully treat the relevant infections before laboratory results are received.
Data for the following infections was compiled:
Urinary tract infections: 175 isolates, to include Escherichia coli (81 isolates), Proteus spp. (39 isolates), Pseudomonas aeruginosa (13 isolates) and Staphylococcus intermedius (42 isolates).
Ear infections: 220 isolates, to include Escherichia coli (16 isolates), Proteus spp. (35 isolates), Pseudomonas aeruginosa (48 isolates) and Staphylococcus intermedius (121 isolates).
Skin infections: 89 isolates, to include Escherichia coli (24 isolates), Proteus spp. (14 isolates), Pseudomonas aeruginosa (5 isolates) and Staphylococcus intermedius (46 isolates).
