Abstract
This study was conducted on (335) pregnant cow which infected with ephemeral fever disease.(238) cow was treated with antibiotic and antipyretic (187 cow multipara and 51 unipara) , and (97) cow was left with out treatment (69 cow multiparp and 28 cow unipara) when the signs of disease appear .Than the percentage of abortion and retained placenta estimated in two groups ( treated and non treated ) and also estimated the total abortion percentage according to pregnancy months. And also subjected to bacteriological study on secretions of aborted fetus to excluded the specific and nonspecific bacteria combined with abortion cases.The results of this study revealed the incidence of abortion in treated cow in ratio ( 10.5%) and (14.43%) in untreated cow; also the results showed that most abortion cases were occurred in the late three months of pregnancy especially in 8th month of pregnancy in ratio (41.02%) from the total cases of abortion.The study also showed the occurrence of retained placenta in treated and untreated aborted cows with ratio (72 , 85.71%) respectively.The results of bacterial study of aborted fetus secretions revealed that the rate of positive bacteriological isolation was (100%) from the total aborted cases ; the nonspecific bacteria formed the most of the bacterial isolation ,and recoded that the E.coli , Streptococcus spp. and Klebsiella spp. the highest rate of isolated microorganisms.
