By the study, it was aimed to isolate the bacteria from sheep lungs with pneumonia and to determine the antibiotic susceptibility. A total of 150 lung samples from sheep with pneumonia was collected at Konya Meat and Fish Abottoir, A total of 60 bacterial agents was isolated from the 38 (25.33 %) of 150 sheep lung. Isolated microorganisms were identified as follows: of 15 (25 %) were Mannheimia haemolytica, 18 (30 %) Mycoplasma spp., 2 (3.3 %) Pasteurella multocida, 9 (15 %) Streptococcus spp., 10 (16.7 %) Staphylococcus spp., 3 (5 %) Aeromonas hydrophila, 1 (1.7 %) Escherichia coli, 1 (1.7 %) Klebsiella pneumoniae and 1 (1.7 %) Pseudomonas spp. In addition; antibacterial susceptibility of bacteria isolated (except Mycoplasma spp.) to various antibiotics were tested by disc diffusion method. Pasteurella spp. isolates were determined susceptible to amoxicillin/clavulanic acid, enrofloxacin, flor-fenicol (100 %), danofloxacin, ampicillin, and furazolidone (94.11 %), oxytetracycline (88.23 %). Staphylococcus spp. isolates were determined susceptibilite to enrofloxacin, florfenicol and oxytetracycline (100 %) amoxicillin/clavulanik asit, danofloxacin (90 %), gentamycin and penicilin (80 %),
