Asymptomatic bacteriuria and antimicrobial susceptibility pattern of the isolates among pregnant women attending Dessie referral hospital, Northeast Ethiopia: A hospital-based cross-sectional study

Background: Group B streptococcus (GBS), also name as Streptococcus agalactiae, is a gram-positive bacterium know for it capacity to colonises the vaginal and rectal areas of the mother and is a leading cause of neonatal mortality and morbidity. This study aimed at determining the prevalence, associated risk factors and antimicrobial susceptibility of GBS colonization among pregnant women attending antenatal care at Dschang District Hospital. Methods: This hospital-base cross-sectional study targeted pregnant women population attending hospitals for routine prenatal testing using a multistage sampling method. Pregnant women at 23.46 ± 6.44 weeks gestation completed a questionnaire and vaginal swabs were obtained for GBS analysis. Data were analysed using chi-squared (χ2) test or the Fisher’s exact test when appropriate and the multivariable logistic regression models. Results: The colonisation rate of GBS among pregnant women was 8.69%. Induce abortion (odds ratio [CI] = 3.09, 95% [1.56-6.21]), Spontaneaous abortions (OR= 2.82, 95% CI 1.14-7.29), Stillborn (OR [CI] = 7.75, 95% [2.61-21.71]), Fever (OR [CI] = 0.37, 95% [0.19-0.71]) and anemia (OR [CI] = 0.22, 95% [0.12-0.43]) were found to be influencing factors associated with GBS colonisation. Conclusion: Our findings suggest that none of the studied factors were significantly associated with GBS colonisation. Further longitudinal research is needed to establish the causal relationship and its biological mechanisms.

Background: The significance of asymptomatic bacteriuria (ASB) relates to its potential to cause acute pyelonephritis, preterm labour and preterm rupture of the membranes. Additionally, it has been associated with clinical conditions such as anaemia, preterm birth, low birth weight and perinatal mortality. Aim: This study, therefore, determined the prevalence of ASB among pregnant women attending the antenatal clinic. Materials and Methods: A cross-sectional study using convenient sampling method was used to recruit 200 pregnant women attending antenatal care at the Korle-Bu Teaching Hospital (KBTH) from January – April 2014. Bacteriological, urine chemistry and routine urine analyses, as well as antibiotic susceptibility profile of bacterial isolates from mid-stream urine samples of pregnant women, were carried out using appropriate standard methods. Variables were reported in mean, standard deviation, percentages and bar graph. Chi-square test was used to establish statistical difference and association between variables where p-value <0.05 was considered statistically significant. Results: Out of the total participants, 23 had asymptomatic bacteriuria but no prevalence of ASB was found among Muslims. The association between marital status and the prevalence of ASB was significant (Pearson chi2 = 4.88, p-value = 0.027). Five bacterial isolates were obtained with Escherichia coli (43.6%) being the most prevalent organism. There were more negative reactions than positive reactions with regards to nitrite and leukocyte esterase determination. Both gram-positive and negative isolates recorded high susceptibility to Gentamicin and Norfloxacin. However, Ciprofloxacin showed a high rate of resistance to only gram-negative isolates whiles Chloramphenicol, Ampicillin and Amoxicillin showed high resistance to gram-positive isolates. Conclusions: The overall prevalence of asymptomatic bacteriuria was 11.5% [95%CI: 7.4% - 16.8%] among the referral pregnant women attending KBTH with Escherichia coli being the most prevalent organism whiles the most susceptible antibiotics were Gentamicin and Norfloxacin.
