Urinary tract infections (UTI) are the most common bacterial infections during pregnancy and these infections. Untreated UTI can be associated with serious obstetric complications. This cross-sectional study was carried out to determine the prevalence of UTI among symptomatic and asymptomatic pregnant women attending Bugando Medical centre (BMC) in Mwanza, Tanzania. A total of 247 pregnant women were enrolled, of these 78 (31.5%) were symptomatic and 169 (68.4%) asymptomatic. UTI was diagnosed using mid stream urine (MSU) culture on standard culture media and urinalysis was done using rapid dip stick. The prevalence of bacteriuria among symptomatic and asymptomatic pregnant women were 17.9% and 13.0% respectively, with no significant difference between the two groups (p = 0.307). Using univariate analysis there was no association of parity (p = 0.825), gestational age (p = 0.173), education (p = 0.615), age (p = 0.211) and marital status (p = 0.949) with bacteriuria. The sensitivity and specificity of urine dipstick was 38.9% and 86.7% respectively. Escherichia coli (47.2%) and Enterococcus spp (22.2%) were the most commonly recovered pathogens. The rate of resistance of Escherichia coli to ampicillin, tetracycline, sulfamethaxazole/trimethoprim, gentamicin, ciprofloxacin, nitrofurantoin, ceftriaxone, and imipenem were 53%, 58.8%, 64.7%, 5.9%, 11.8%, 5.9%, 29.4% and 0%, respectively. In conclusion, asymptomatic bacteriuria among pregnant women is prevalent in our setting and majority of Escherichia coli are resistant to ampicillin, tetracycline, SXT and ceftriaxone. Due to low sensitivity of rapid dip stick, routine urine culture and susceptibility testing is recommended to all pregnant women at booking.
"reported a prevalence of 21.7% but relatively lower that the study of Onuh et al. (2006) in Benin with a 32.7% prevalence rate and Okonko et al. (2009) with a prevalence rate of 45.7% in Ibadan. However, it is higher than the study in Abakaliki by Onyemelukwe et al. (2003) who reported a prevalence of 12.7% and 14.6% prevalence in Tanzania by Masinde et al., 2009. In other parts of the world, 8.5% by Sevki et al. (2011), 10.4% by Agersew et al. (2012) and 10.4% by Nawaz et al. (2012). "
"In our study the sensitivity and specificity of urine dipstick (nitrate and leukocyte esterase in combination) was 22.9% and 99.1% respectively which is comparable with the study done by Masinde et al. in Tanzania, who reported the sensitivity and specificity of the dipstick test result 38.9% and 86.7% respectively. In the current study the sensitivity of leukocyte esterase and nitrite was 51.4% and 42.9%, while its specificity was 88.9% and 98% which has similar pattern with the study reported by Kacmaz et al. where the sensitivity of urine leukocyte esterase and nitrite was found to be 70% and 60%, and specificity was 92.5% and 99.2% respectively.

[Show abstract][Hide abstract] ABSTRACT: Background
Untreated bacteriuria during pregnancy has been shown to be associated with low birth-weight and premature delivery. Therefore, routine screening for bacteriuria is advocated. The decision about how to screen pregnant women for bacteriuria has always been a balance between the cost of screening versus the sensitivity and specificity. This study was designed to evaluate the diagnostic accuracy of the rapid dipstick test to predict urinary tract infection in pregnancy against the gold standard urine culture.
A total of 367 mid stream urine samples were collected, inoculated on MacConkey, Manitol salt agar (MSA) and blood agar and incubated aerobically at 37°C for overnight. Specimens were classified as “positive” for urinary tract infection (UTI) if the growth of the pathogen(s) was at a count ≥ 105 colony-forming units per milliliter (cfu/mL) of urine and classified as “negative” with growth of <105 cfu/mL. Urine samples were tested for the presence of nitrite and leukocyte esterase using dipstick rapid test in accordance to the manufacturer’s instructions.
From the total study participants, 37 pregnant women were symptomatic and the remaining 330 pregnant women were asymptomatic. The sensitivity and specificity of dipstick tests of leukocyte esterase was 50% and 89.1% for pregnant women with asymptomatic UTI(ABU) and 71.4% and 86.7% for symptomatic UTI respectively and for nitrite 35.7% and 98.0% for ABU and 57.1% and 96.7% symptomatic UTI.
This study revealed that the use of dipstick leukocyte esterase and nitrite for screening UTI particularly asymptomatic bacteriuria was associated with many false positive and negative results when it was compared against the gold standard culture method. The low sensitivity and positive predictive value of urine dipstick test proved that culture should be used for the diagnosis of UTI.

"respectively. Similar findings were also reported in previous studies in Ethiopia  and Tanzania  from pregnant women. In this study, a statically significant bacteriuria was found among divorced study participants. "
[Show abstract][Hide abstract] ABSTRACT: Many women die from complications related to pregnancy and childbirth. In developing countries particularly in sub-Saharan Africa and Asia, where access to emergency obstetrical care is often limited, obstetric fistula usually occurs as a result of prolonged obstructed labour. Obstetric fistula patients have many social and health related problems like urinary tract infections (UTIs). Despite this reality there was limited data on prevalence UTIs on those patients in Ethiopia. Therefore, the aim of this study was to determine the prevalence, drug susceptibility pattern and associated risk factors of UTI among obstetric fistula patients at Gondar University Hospital, Northwest Ethiopia.
A cross sectional study was conducted from January to May, 2013 at Gondar University Hospital. From each post repair obstetric fistula patients, socio-demographic and UTIs associated risk factors were collected by using a structured questionnaire. After the removal of their catheters, the mid-stream urine was collected and cultured on CLED. After overnight incubation, significant bacteriuria was sub-cultured on Blood Agar Plate (BAP) and MacConkey (MAC). The bacterial species were identified by series of biochemical tests. Antibiotic susceptibility test was done by disc diffusion method. Data was entered and analyzed by using SPSS version 20.
A total of 53 post repair obstetric fistula patients were included for the determination of bacterial isolate and 28 (52.8%) of them had significant bacteriuria. Majority of the bacterial isolates, 26 (92.9%), were gram negative bacteria and the predominant ones were Citrobacter 13 (24.5%) and E.coli 6 (11.3%). Enterobacter, E.coli and Proteus mirabilis were 100% resistant to tetracycline. Enterobacter, Proteus mirabilis, Klebsella pneumonia, Klebsella ozenae and Staphylococcus aureus were also 100% resistant to ceftriaxone.
The prevalence of bacterial isolates in obstetric fistula patients was high and majority of the isolates were gram negative bacteria. Even thought the predominant bacterial isolates were Citrobacter and E.coli, all of the bacterial isolates had multiple antibiotic resistance patterns which alert health profession to look better treatment for these patients.
