We included 92 pairs of ewes with or without retention of fetal membranes in a cohort study of 25 Rocks in Southern Greece. We obtained two uterine content samples under aseptic conditions, by Introducing a swab into these ewes, on the 2ndth and 5th - 9th day after lambing We used conventional bacterial methods to isolate and identify bacteria and to carry out antimicrobial agents stisibility testing. The prevalence of bacterial intrauterine contamination among ewes with retention W18 24% on the first and 46% on the second sampling (P <0,0001) and that among ewes without retention was 8 and 2 (P> .05), respectively. Clinical signs accompanying the retention of fetal membranes were more frequently observed among ewes with intratterine contamination than among those without (P = .0 0007). The odds of an ewe having an intrauterine contamination increased multiplicatively by 1. 06 when the median duration of retention in the Aok increased by 6h. The principal bacterium Isolated from the ewes with retention were Archiobacteriumpyogenes and Estellerichia col: 21% of 73 isolates tested were found resistant to at least one antimicrobial agent.
