مقايسه نتيجه تستهاي سرولوژي با آنتي ژن انستيتو پاستور و انستيتو رازي در بيماران مشكوك به بروسلوز

A COMPARISON OF THE RESULTS OF SEROLOGICAL TESTS IN SUSPECTEDʹ CASES OF BRUCELLOSIS USING ANTIGENS FROM THE PASTEUR AND RAZI INSTITUTES AT THE CENTRAL LABORATORY

Considering the report on the difference in results of the Wright test with the antigens of Pasteur Institute and Razi Institute in order to diagnose Brucellosis, it was decided to compare these two antigens in this study . The serum of 50 patients from 345 patients who had a positive Wrights with one or both of these Antigens were included in this study . It was a descriptive cross-sectional study . The procedure included an interview and a questionnaire with details of demographic characteristics such as age,sex, job,any background of Malta fever and consumption of nonpasteurized dairy products. 5cc of blood was taken from each subject and after screening the serum , Wright serologic tests were carried out with the antigens of Pasteur and Razi Institutes. Of the 50 subjects under study, 27 (54%) were male and 23 (46%) were female. The age range of the subjects was from 8 to 60 years. The results of rapid Wright using the antigens of Pasteur and Razi Institutes showed a significant difference (PV=0.001). Similarly, the results of the tube Wright test with the antigens of Pasteur and Razi Institutes were significantly different. In conclusion, with rapid procedure , zone phenomenon is observed with the antigens of the Pasteur Institute while no such phenomenon is observed with antigens of the Razi Institute. Also , the tube procedure with the antigens of Pasteur Institute indicates a high titer antibody as compared to the antigens of Razi institute .
