Recognition of Bacteria causing Urinary tract infection in pregnant women of Abadan city and study of Antibiotic resistance of these bacteria

Physiological changes due to the hormonal alterations during pregnancy, lead to the changes in chemical properties of urine and facilitate the growth of the microorganisms. The aim of this study was to assess the prevalence of bacteriuria and its relevance to some demographic parameters of pregnant women referred to Dr. Sehatti laboratory of Abadan city.Sampling was conducted by collected of the middle urine sample and samples were analyzed using biochemical tests, microbial culture and antibiogram. Results showed that 54.4% of examined women had the pyuria and 28.8% had bacteriuria.Study of different parameters showed that there was no significant relation between the bacteriuria and age, education level, diabetes history and taking medicines. Results showed that almost half of the examined pregnant women had the history of urinary tract infection and proteinuria was more significant in such patients. In this study Staphylococcaceae family was the most abundant agent for urinary tract infection and after that; there were Streptococcaceae and Enterobacteriaceae respectively. Results of the antibiotic resistance showed that the examined bacteria had the most resistance to Clindamycin, Tetracycline, Azithromycin, and Cefoxitin, and the most sensitivity to Gentamicin, Nitrofurantoine, Ampicillin, and Cotrimoxazole. The bacteria isolated from the specimens in a culture medium were tested according to the antibiogram method.According to results of the present study, pregnant women of third trimester were more susceptible to urinary tract infections and demographic parameters had no significant effects on occurrence of urinary tract infection in pregnant women.
