[The cross-section study of CMV isolation in infants' urine and mothers' breast milk].

One hundred and eighty-three normal healthy infants' urine and 73 mothers' breast milk were examined for CMV acquired infection by virus isolation. The total positive rate of infection in infants' urine and breast milk were 56.8% (104/183) and 47.9% (35/73) respectively. Among the 67 mother-baby pairs, consumption of infected and uninfected breast milk led to CMV infection of 68.5% (24/35) and 43.7% (14/32) of the infants respectively, which showed significant difference (chi 2 = 4.19, P less than 0.05). Our study showed that infected breast milk feeding may be a way of CMV acquired infection during the first year of life, and we should pay more attention to it.
