M.H. Shirazi, N. Sadeghifard, R. Ranjbar, E. Daneshyar and A. Ghasemi


Incidence of asymptomatic bacteriuria during pregnancy among Iranian women was examined. Midstream urine was collected from 380 pregnant women and streaked on blood agar and incubated for 24 to 48 h. Growth was considered significant if 105 mL-1 bacteria were present. Among the pregnant women, 10.1% had asymptomatic bacteriuria. Age, past history of abortion, proteinuria, level of education, number of fertility had no significant association with asymptomatic bacteriuria occurrence. But lower socioeconomic status, leucocytosis and a history of UTI were associated with an increased incidence of asymptomatic bacteriuria (p<0.05). The most frequently isolated pathogen was Escherichia coli (68.4%), followed by Staphylococcus epidermidis (10.5%)) and Klebsiella pneumonia (8.3%). According to the results, co-trimoxazole was the best antibiotic; followed by nitrofurantoin which 60.5 and 44.7% of strains were sensitive to these two antibiotics, respectively.
