Antimicrobial susceptibility of Ornithobacterium rhinotracheale isolated from broiler chickens in Turkey
نویسندگان
چکیده
Minimum inhibitory concentrations (MICs) of eight antimicrobial agents were tested for 11 Ornithobacterium rhinotracheale isolates and for one type strain. Of the eight antibiotics examined, oxytetracycline was the most active antibiotic with MIC ranges of < or = 0.125 1 μg/ml for O. rhinotracheale isolates. All isolates were resistant to gentamicin and neomycin. Resistance to doxycycline occurred only in the type strain. All other isolates were found to be sensitive to doxycycline. Tilmicosin (MICs ranging from < or = 0.5 4 μg/ml), erythromycin (MICs ranging from < or = 0.5 8 μg/ml), and penicillin G (MICs ranging from < or = 4 16 μg/ml) gave good inhibitions, but with most strains in a higher concentration.

Isolation of Ornithobacterium rhinotracheale from the brains of commercial broiler breeder chickens with meningitis and encephalitis
Ornithobacterium rhinotracheale (ORT) has been identified as one of the respiratory bacterial pathogens in turkey and chicken flocks. Four live birds displaying severe torticollis were submitted from a 13-week-old commercial broiler breeder chicken flock located in Mazandaran province. These birds were suspected to pasteurellosis by the farm veterinarian. No other marked gross lesion except ema...

Respiratory disease conditions continue to cause heavy economic losses in the poultry industry. They are usually caused by viral, bacterial, mycotic or parasitic agents and the course of the diseases can be influenced by environmental conditions and management failure (JOUBERT et al., 1999). At the beginning of 90`s bacteriological examinations from turkeys and chickens suffering from respirato...
