Abstract

An agar disc diffusion method was used to examine the sensitivity of 27 Haemophilus paragallinarum (Hpg) isolates consisted of 23 local isolates, 4 standard isolates (serotype A) and Escherichia coli ATCC 24922 as a control to eight antimicrobial drugs (ampicillin, erythromycin, oxytetracycline, doxycycline, neomycin, streptomycin, colistine and sulphanlethoxazole-trimethoprim) . Twenty one out of 23 local isolates of Hpg were sensitive to doxycycline, 19 isolates to ampsllin, 18 isolates to oxytetracycline, 17 isolates to sulphametoxazole-trimethoprim, 16 isolates to erythromycin, and 13 isolates to neomycin, while 13 isolates were resistance to colistine and 11 isolates were also resistance to streptomycin .
