Oral administration of enrofloxacin at doses of 7.5 and 10mg for 30 successive days into mature rats significantly increased the frequencies and percentage of micro nucleated polychromatic erythrocytes (MPCEs) and ratio of polychromatic erythrocytes normochrotic erythrocytes ( PCE / NCE) was recorded.
