The Comparison of Different Selective Media into Isolation of Brucella spp. from Cattle and Sheep Abortion

In this study, between the period of October 2012 and January 2013, abort material of 20 cattles, 68 sheeps, 9 goats and 2 buffalos with in totally 100 abort sample which were sent from region of Marmara to Pendik Veterinary Institute were investigated about the presence of Brucella bacteria. Abomasum content and homogenates from internal organs of the aborted fetuses were inoculated into Farrell?s medium, modified Thayer Martin medium and CITA medium. Suspicious colonies by Brucella spp.were observed in Farrelll's Medium 34 (%34) times, in Modified Thayer Martin Medium 29 (%29) times and in CITA Medium 32 (%32) times , after inoculation of 100 abort sample. Consequently, CITA medium should be evaluated as a beneficial tool for isolation of Brucella species which is a veterinary field sample. However, using CITA medium, Farrell?s medium and modified Thayer Martin medium simultaneously, guarantee the best determination performance of first isolation of abort material.
