Bacterial study of vagina in Awassi ewes treated with Prostaglandin (PGF2 α) and oxytocin


This study was carried on 21 Awassi ewes postpartum, the age of the animals ranged between 3-5 years. The animals were divided in to 3 groups (each group contain 7 animals). The first group was treated with 7.5 mg of prostaglandin F2α. The second group was treated with 20 IU oxytocin the third group was considered as a control group and was treated with 2 ml of normal saline. Bacterial swabs were taken from the vagina. The result revealed that there were 6 different types of bacteria, the predominant bacteria in the vagina of ewes were E.coli, and Staphylococcus aureus while Pseudomonas aeruginosa and Proteus vulgaris were less frequent isolates. The result showed that the number of all species of bacteria in PGF2α treated group less than in other groups. There were a significant differences (p>005) between the first group and the other two groups, While the number of vaginal bacteria did not affected in oxytocin treated group. It was concluded from this study that treatment of ewes with PGF2α postpartum reduce the bacterial flora of the vagina and metritis keeping of the ewes under non stressful condition is warranted to avoid clinical infection of reproductive tract with opportunistic bacteria
