The impact of Ureaplasma infections on pregnancy complications

Figures & data

Table 1. Characteristics of the women and the newborns.

Characteristics
Number of women	50
Age, mean, (95% CI) (range)	30 (28–32, 18–44)
Gestational week, mean, (95% CI) (range)	29 (28–30, 19–36)
Premature rupture of uterine membranes, n (%)	23 (46)
Inflammation of placenta	22 (44)
Thick leukocytosis in Gram stain, n (%)	15 (30)
Ureaplasma infection (total), n (%)	26 (52)*
Ureaplasma parvum infection, n (%)	24 (48)
Ureaplasma urealyticum infection, n (%)	6 (12)
Mycoplasma genitalium infection, n (%)	4 (8)
Chlamydia trachomatis infection, n (%)	2 (4)
Number of newborns	53
Gestational age of the newborns, mean, (95% CI) (range)	31 (30–33, 19–40)
Newborn congenital infection, n (%)	34 (64)
Newborn respiratory distress syndrome, n (%)	25 (47)

*The total number of cases with Ureaplasma infection is less than the sum of all cases with Ureaplasma parvum and Ureaplasma urealyticum infections because there were cases with both infections.
