In this study, five abattoirs in Istanbul were visited between January 2000 and April 2001. During these visits, 330 cattle were selected by a systematic sampling method. Cattle were examined clinically and breed, age, and sex were recorded. Rectal swabs were taken immediately after slaughter. Immunomagnetic separation was performed, and sorbitol-negative colonies were selected on sorbitol MacConkey agar with cefixime and tellurite (CT-SMAC agar). These colonies were checked for 4-methylenebelliferyl-β-d-glucuronide, indol, rhamnose, and urease activity and motility. Serotypes of bacteria were determined by using antisera specific for Escherichia coli O157 and H7. All cattle selected were clinically healthy. Of 88 sorbitol-negative colonies selected on CT-SMAC agar, isolates from only 14 (4.2%) cattle reacted with anti-O157, and 13 of these isolates also reacted with anti-H7. E. coli O157:H7 was isolated from all breeds, but the numbers of isolates were largest for Holstein and Swiss Brown cows. E. coli O157:H7 was most frequently isolated from 2-year-old cattle. Similarly, it was most frequently isolated from male cattle. E. coli O157:H7 was isolated from cattle slaughtered in four of the five abattoirs studied.

The background of this research was based on the continued development of international aviation in the world which was a challenge for the translator to find an equivalent sentence. The purpose of this thesis was to find the equivalence type used in translating the source language to the target language and find the dominant equivalence type used. For solving this problem, the writer used Nida and Taber theory that divided equivalence types into two types, namely formal equivalence or formal correspondence and dynamic equivalence. The method used was descriptive qualitative method. The data was obtained through systematic sampling method. Based on the analysis, the equivalence types of 53 of 66 samples (80%) were translated by using formal correspondence; 12 of 66 samples were translated using dynamic equivalence (18%) and only one sample (2%) did not neither involve in formal correspondence nor dynamic equivalence because SL text did not have translation in TL (reserved). The most dominant equivalence type used in the translation was formal correspondence.
