Abstract

Eighteen isolates of Ornithobacterium rhinotracheale isolated from laying hens in India were tested for their susceptibility to various antibiotic agents. Antibiogram pattern of all the 18 O. rhinotracheale isolates were determined in Mueller Hinton agar enriched with 10 per cent sheep blood, with antibiotic discs. All the isolates were resistant to amikacin, cloxacillin, co-trimoxazole, gentamicin, metronidazole and triple sulpha. Susceptibility of O. rhinotracheale isolates to cephalexin, norfloxacin, pefloxacin, streptomycin and furazolidone was variable. The isolates were sensitive to amoxycillin, ampicillin, chloramphenicol, ciprofloxacin,
doxycycline, enrofloxacin, erythromycin, oxytetracycline, and penicillin-G.
