This study was designed as an attempt to isolate and identify the Campylobacter organisms prevalent in farm animals as well as studying their antibiotic sensitivity invitro to commonly used antibiotics. Three hundred and seventy three random samples were collected from cattle. buffaloes and sheep allover different private farms in Khalubia, Sharkia. tsmalia. El—Nobarea and Cairo abattoir to detect the possible existance of Campytobecter fetus in such specimens, cultural characters. morphological characters and biochemical criteria were done to identify the isolated strains. The obtained data revealed the presence of Cempylobecter fetus subsp < /p> venereefis in cattle with an incidence ot(11.73%)whero 27 strains were obtained from 230 samples and it was (12.28%) as 7 isolates were recovered from 57 examinaed samples while Campylobacter fetus was isolated from sheep gall bladder with recovery rate of 4.65% as 4 isolates were obtained from 86 samples. The invitro antibiotics sensitivity test was done against the commonly used antibiotics and the obtained data proved that isolates of Cempylobacter fetus subsp. venereeiis were sensitive to nitrofurantion, erythromycin, trimethoprim, streptomycin, chloramphenical with activity of 100%, 97.05%. 97.50%. 91.17% and 85.29% respectively. While isolates of Cempydobacter fetus subsp. fetus were sensitive to erythromycin nitroturantion, trimethoprim, streptomycin. and chloramphenlcol with an activity of 100%. 75%, 75%, 50%. and 50%, respectively.
