Abstract :
The objectives of this studies were to investigate the effect of washing on development of embryos wich experimentally exposed with K99 E.coli. The embryos were exposed to K99 E.coli in appropriate amount of 103 CFU/ml and then incubated at 370C for an hour, then they were devided into three groups. The first group were washed with mPBS and KSOM, the second group of embryo were treated with trypsin for 90 second, the third group were treated with pronase for 60 second. Each group of the embryos were washed 6 times in mPBS and 4 times in KSOM, Thereafter, the embryos were cultured in the drops of KSOM without antibiotic and incubated in incubator 5% CO2 at 370C. The development embryos were observed every six hours interval for 48 hours period. The result of this studies showed that the development of pronase treated embryos were better than that of the mPBS washing and the trypsin treated. In conclussion of the present studies show that the development of embryos could be influenced by the K99 E.coli contaminated medium. Trypsin and pronase treatment could minimize the negative effect of K99 E.coli on embryos under in vitro conditions.
