Klebsiella spp. were included from infections of the genita tract (GT) of horses (36 isolates) and the urinary/genital tract (UGT) from dogs and cats (17 isolates), while Proteus spp. were from small animal (dogs and cats) infections of the UGT (37 strains) and the skin (incl.ear/mouth) (30 isolates). In Klebsiella spp. resistance appeared most freguently to ampicillin (53-67 %), sul-famethoxazole (19-29 %) and potentiated sulfonamides (trimethoprim/sul-famethoxazole 1/19 combination) (19-24%).A further 29 % of enrofloxacin resis-tant Klebsiella isolates were observed for the UGT of small animals. From the GT of horses for this antimicrobial agent there was no isolate detected with a comparably high minimum inhibitory concentration (MIC) value. In Proteus spp. highest percentages of resistance occurred against tetracycline (90-92 %). Due to drug efflux proteins, high MIC values against this antimicrobial agent have been freguently reported in literature. In Proteus spp. relevant resistance percentages also occurred for potentiated sulfonamides (27-37 %), sulfamethoxazole (24-37 %) and chloramphenicol (24-37 %).}, year = {2007}, journal = {Berliner und Münchener Tierärztliche Wochenschrift}, volume = {120}, pages = {402-411}, month = {09/2007}, publisher = {Schlütersche Verlagsgesellschaft mbH & Co.
