Introduction: Asymptomatic bacteriuria (ASB) is the presence of actively multiplying bacteria within the urinary tract with absence of any symptoms, resulting in adverse pregnancy outcomes. This research study was done in order to review prevalence, antimicrobial susceptibility profile, and factors associated with ASB occurring in female patients who are pregnant and being treated at a tertiary care hospital in Lucknow, India. Method and Materials: This is a cross-sectional study done among 216 pregnant women attending a hospital for antenatal check-ups. Clean catch midstream urine samples were collected and examined microscopically, and semi-quantitative culture was done on blood agar and MacConkey agar. Isolates were identified by colony morphology and biochemical tests, and antimicrobial susceptibility testing was done by using the Kirby-Bauer method. Results: Of the 216 pregnant women, 36 (16.7%) tested positive for ASB. The female gestational period, haemoglobin level, and BMI were significantly associated with ASB. Logistic regression also showed that higher haemoglobin level was less likely to ASB (AOR = 0.42, 95% confidence interval: 0.202–0.88, p = 0.021). The predominant and usual isolates were E. coli (n = 22, 61.1%), followed by Cons (n = 6, 16.7%), and S. aureus (3, 8.3%). All Gram-negative isolates were mostly sensitive to most of the drugs like piperacillin-tazobactam, cefepime, nitrofurantoin, and meropenem but were 100% resistant to ampicillin. Similarly, Gram-positive isolates were sensitive to ampicillin, vancomycin, linezolid, and nitrofurantoin but 100% resistant to co-trimoxazole. Conclusion: The present study shows the existence of ASB was 16.7% among women who are pregnant. Pregnancy duration, haemoglobin level, and BMI were significantly associated with ASB. The isolates identified more frequently were E. coli (61.16%), Cons (16.7%), and S. aureus (8.3%). All isolates which were Gram-negative were mostly sensitive to most of the drugs but were 100% resistant to ampicillin. Similarly, Gram-positive isolates were sensitive to most of the drugs but 100% resistant to co-trimoxazole.

Background and Objectives: The association between bacterial vaginosis and urinary tract infection (UTI) in pregnant women is at a greater risk comparatively than patients with bacterial vaginosis or UTI. Bacterial vaginosis and asymptomatic UTI both pose risk for  mother and fetus. Early diagnosis and treatment can save the life of both. The present investigation was aimed to find out the magnitude of asymptomatic bacteriuria in pregnant women with noticeable bacterial vaginitis at- tending antenatal outpatient and inpatient of a tertiary care hospital and to identify the organisms causing it. Materials and Methods: A total of 117 antenatal women from different age and parity groups with different gestational ages were included in the study. The samples were subjected to standard microbiological techniques for identification of micro- organisms. While performing Per speculum examination, vaginal secretions were collected from the posterior fornix. Swabs from the posterior fornix were tested for pH using litmus paper. A wet mount and Gram smear was made and examined for the presence of bacteria, polymorphs and clue cells indicating bacterial vaginosis. Amsel’s criteria and Nugent scoring sys- tem were applied for diagnosis of bacterial vaginosis. Antibiotic susceptibility of the isolated bacteria was performed using Kirby-Bauer method. Results: Bacterial vaginosis infection rate (62.3%) was common in the present study followed by asymptomatic UTI (n=60, 51%). It was also observed that asymptomatic urinary tract infection (UTI) with Bacterial vaginosis prevalent rate was 49 (41.8%) in the current study. Conclusion: Bacterial vaginosis was more common than asymptomatic bacteriuria in pregnant women. It is recommended that antenatal health care facilities should incorporate screening of vaginitis among pregnant women to prevent the complica- tions of pregnancy. And those women with Bacterial vaginosis should be screened for UTI. Proper use of antibiotics should be encouraged, abuse of antibiotics should be in check.

Background: Asymptomatic bacteriuria (ASB) is defined as the presence of actively multiplying bacteria, which is greater than 105/ ml of urine within the urinary tract excluding the distal urethra, at a time when the patient has no symptoms of UTI. Untreated and undiagnosed ASB is associated with adverse maternal and perinatal outcomes. The objective was to determine the profile, prevalence, microbiological isolates with susceptibility, and risk factors of ASB among pregnant women attending an antenatal clinic at a tertiary care hospital, Andhra Pradesh, India.Methods: A prospective cross sectional study with 200 pregnant women was conducted for a period of 3 months from January to March 2016. The mid- stream urine specimen was collected and processed from all the cases and social and baseline obstetric data was collected. The isolates from all the cases of ASB were identified by standard biochemical tests. Antimicrobial susceptibility was performed by Kirby- Bauer disc diffusion method and interpreted as per CLSI guidelines.Results: Prevalence of ASB in our study was 30.5%, mean age of the cases was 27.3± 2.9 years. ASB was most common in 25- 30 year’s age group, during 3rd trimester and among multiparous and multigravidae. Previous history of UTI, pre-eclampsia was having significant association among cases with ASB. Escherichia coli was the predominant isolate in the study followed by K. pneumoniae, CONS (Coagulase-Negative Staphylococci), Staphylococcus aureus, citrobacter and Enterococci.Conclusions: Undiagnosed and untreated asymptomatic bacteriuria is associated with complications during pregnancy. Hence routine screening of antenatal women during all trimesters must be considered in preventing the complications and adverse foetal outcomes particularly with known risk factors like increasing age, multiparity and previous history of UTI.

Background: Asymptomatic bacteriuria (ASB) is common in pregnant women due to morphological and physiological changes in the genitor-urinary tract, which untreated may lead to complications like pyelonephritis and may also effect the fetus. The objective of our study was to determine the prevalence of ASB in pregnant women, to identify the organisms responsible and their antibiotic sensitivity pattern.Methods: A clean catch midstream urine was collected from 250 pregnant women in different trimesters attending antenatal OPD in a tertiary care hospital. Isolates and their antibiogram were obtained by conventional methods.Results: Among 250 pregnant women, 23(9.2%) had shown significant bacteriuria, and majority (52.1%) were in 3rd trimester. Escherichia coli (56.5%) was the commonest isolate followed by Klebsiella pneumoniae (17.4%). Most of the isolates showed sensitivity to imipenam, nitrofurantoin and cefepime.Conclusions: Asymptomatic bacteriuria is common during pregnancy which requires a routine examination of urine for culture and sensitivity and the positive cases should be treated with appropriate antibiotics to prevent any further complication.

Asymptomatic bacteriuria (ASB), most common during pregnancy is endangering as it may lead to maternal and fetal complications. Various organisms causing ASB combats the host defense mechanisms through virulence factors exhibited by them. In order to understand the pathogenesis and sequelae of infections, virulence factors like hemolysin production, gelatinase production, haemagglutination, biofilm production and many more should be identified. Hence, we aimed at studying the distribution of virulence factors among each organism causing asymptomatic bacteriuria in pregnant females attending a tertiary care hospital. Materials and Methods: This cross-sectional study was conducted in Department of Microbiology over a period of one year and six months (January 2014 to June 2015) at a tertiary care teaching hospital. A total of 1000 urine samples were included in study taken from pregnant women with asymptomatic bacteriuria. Isolation, identification of organisms was done according to standard microbiological techniques and virulence factors for individual organisms by phenotypic method were tested. Results: Out of 1000 samples screened for ASB, organisms were isolated in following frequency distribution: Escherichia coli, the commonest 54/118 (45.76%), Klebsiella pneumoniae 21/118 (17.80%), Staphylococcus aureus 19/118 (16.10%), Staphylococcus saprophyticus 10/118 (8.45%), Enterococcus faecalis 9/118 (7.63%), Pseudomonas aeruginosa 3/118 (2.54%) and Proteus mirabilis 2/118 (1.69%). Virulence factors for individual organisms and biofilm detection for all organisms were done. Conclusion: Multifactorial mechanisms determine the pathogenicity of an organism and it needs to be explored by analyzing each virulence factor and mechanism of invasion in combating the host defense systems. Hence analyzing the phenotypic expression of each virulence factor helps in better understanding about the complications of ASB.
