Background. Maternal Streptococcus agalactiae (Group B Streptococcus (GBS)) colonization is an important cause of complications in mothers and neonates during gestation and after delivery. The data regarding GBS colonization among pregnant women in Palestine is scarce. The aim of this study is to determine the prevalence of GBS colonization, its associated risk factors, and the antibiotic sensitivity patterns in Nablus, West Bank, Palestine. Methods. A cross-sectional, single center study conducted at Rafidia Governmental Hospital in Nablus, West Bank, Palestine. Samples were collected between November 2019 and January 2020. Vaginal swabs from 200 pregnant women (≥35 weeks of gestation) attending the labor and delivery department were plated directly on CHROMagarTM StrepB (CHROM agar, France) and placed in an incubator at 35–37°C. After 24 and 48 hours, the plates were checked for growth and classified into three categories: growth of GBS with mauve colonies on chromogenic media, no growth, or other growth. The identification of the mauve colonies was confirmed by the CAMP test. Identified GBS isolates were tested for susceptibility to vancomycin, ampicillin, clindamycin, cefotaxime, erythromycin, and levofloxacin using the disc diffusion method. Clinical and demographic information were collected using a questionnaire. Result. The overall prevalence of GBS colonization was 12%. The median age of the study population was 27 years. GBS colonization was significantly associated with age ( p = 0.013 ), history of previous preterm delivery ( p = 0.013 ), and parity ( p = 0.015 ). No association was noted with smoking, previous abortion, previous history of fetal demise, vaginitis, or urinary tract infection. Resistance to ampicillin, vancomycin, cefotaxime, erythromycin, clindamycin, and levofloxacin was found to be 91.7%, 54.2%, 45.8%, 29.2%, 25%, and 8.3%, respectively. Conclusion. The prevalence of vaginal GBS in this study was 12% from Nablus, West Bank. Further research is needed to determine the GBS serotypes common in West Bank and the burden they cause on the health system. Moreover, this study also highlights the need to establish a screening program suited to a developing country with low control on the antibiotic’s prescription protocols.

Group B streptococcus (GBS) is a leading cause of serious neonatal infections. Maternal GBS colonization is associated with early- and late-onset neonatal disease (EOD/LOD). In Greece, a screening-based strategy is recommended, in which concurrent vaginal-rectal cultures should be obtained between 36 0/7 and 37 6/7 weeks’ gestation. We sought to examine the level of adherence to the GBS screening guidelines and estimate the prevalence of GBS colonization among pregnant women. Although in Greece the screening-based strategy is followed, we also examined known EOD risk factors and linked them to GBS colonization. A cross-sectional study of 604 women postpartum in three hospitals and maternity clinics was conducted. Following written informed consent, data were collected via a short self-completed questionnaire and review of patients’ records. In 34.6% of the enrolled pregnant women, no culture had been taken. Of the remaining, 12.8% had proper vaginal-rectal sample collections. The overall maternal colonization rate was 9.6%. At least one risk factor for EOD was identified in 12.6% of participants. The presence of risk factors was associated with positive cultures (p = 0.014). The rate of culture collection did not differ between women with or without an EOD risk factor. Adherence to a universal screening of pregnant women with vaginal-rectal cultures was poor. Despite probable underestimation of GBS carrier status, almost 1 in 10 participants were GBS positive during pregnancy. Screening of women with risk factors for EOD should, at least, be prioritized to achieve prevention and prompt intervention of EOD.

Introduction: The purpose of this study was to investigate group B streptococcus (GBS) colonization, to compare the methods, to determine the relationship between GBS carriage and risk factors, and to genotype the GBS isolates. Methodology: Recto-vaginal swab specimens were obtained from 500 women, and a questionnaire was administered to each to assess their risk factors for GBS carriage. A culture, GBS antigen test, and polymerase chain reaction (PCR) were performed on all samples. Antibiotic susceptibility testing was performed, and the clonal relationship was determined by pulsed-field gel electrophoresis (PFGE) on all viable isolates. Results: Of the 500 women, sixty-eight (13.6%) women were GBS carriers, of whom 9.8% were pregnant and 16.5% not. There was a significant difference between GBS carriage and history of premature rupture of membrane (PROM). GBS was isolated from 65 (13%) samples. GBS was positive in 70 (14%) samples by antigen test and in 62 (12.4%) by PCR. Sixty-eight of the 70 positive antigen tests were confirmed by PCR or culture. Fifty-five isolates were resistant to tetracycline, 16 to erythromycin and clindamycin, and 13 to levofloxacin. Thirteen different pulsotypes and 17 sporadic strains were determined by PFGE. Conclusions: GBS carriage rate in non-pregnant women was higher than in pregnant women. The GBS antigen test was more sensitive than culture and PCR. GBS isolates did not originate from a single clone and contained sporadic strains. There was a significant difference between GBS carriage and history of PROM. Epidemiologic data obtained in this study will help future studies.

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: Asymptomatic bacteriuria (ASB) is a relatively common condition occurring due to the morphological and physiological changes in the genitourinary tract during pregnancy. If left untreated, it may lead to acute pyelonephritis and adverse fetal and maternal outcomes. The objective was to determine prevalence, risk factors and etiological agents with susceptibility for ASB among pregnant women attending an antenatal clinic at a tertiary care hospital, Odisha, India.Methods: A prospective study with 200 pregnant women was conducted, over a period of 4 months, starting from 1st April 2017 to 31st July 2017. The mid- stream clean catch urine specimen was collected and processed in all the cases and other data were collected from the questionnaire given to them. The isolates from all the cases of ASB were identified and antimicrobial susceptibility was tested by Kirby- Bauer disc diffusion method and interpreted.Results: Prevalence of ASB in our study was 25.3%, with maximum prevalence among age group 21-30 yrs, during 3rd trimester, among multigravidae. Previous history of urinary tract infection (UTI), anaemia and diabetes have significant association with ASB. Klebsiella spp. was the predominant isolate in this study followed by Escherichia coli. Nitrofurantoin and Cefixime are safe and effective antibiotics against urinary pathogens in pregnancy.Conclusions: Undiagnosed and untreated asymptomatic bacteriuria is associated with complications during pregnancy. Hence routine screening of antenatal women for ASB during all trimesters must be considered for preventing the adverse maternal and foetal outcomes particularly with known risk factors like increasing age, multiparity and previous history of UTI.

Abstract Background Infection causes 1 of every 5 neonatal deaths globally. Group B Streptococcus (GBS) is the most significant pathogen, although little is known about its epidemiology and risk in low-income countries. Methods A cross-sectional study in 2015 at a public hospital in Guatemala City enrolled women ≥35 weeks’ gestation. Vaginal and rectal swabs were processed using Lim broth and GBS CHROMagar then agglutination testing. Risk factors were assessed using multivariate analysis. Vaginal microbiota were profiled by 16S ribosomal ribonucleic acid sequencing in a subset of 94 women. Results Of 896 pregnant women, 155 (17.3%; 95% confidence interval [CI], 14.9–19.9) were GBS colonized. Colonization was associated with history of previous infant with poor outcome (odds ratio [OR], 1.94; 95% CI, 1.15–3.27) and increasing maternal age (OR, 1.05; 95% CI, 1.02–1.09). Multiparity was protective (OR, .39; 95% CI, .21–.72). Four (6%) GBS-exposed infants had early-onset neonatal sepsis. Vaginal microbiome composition was associated with previous antibiotic exposure (P = .003) and previous low birth weight infant (P = .03), but not GBS colonization (P = .72). Several individual taxa differed in abundance between colonized and noncolonized women. Conclusions Group B Streptococcus is prevalent in pregnant women from Guatemala with different risk factors than previously described. Although the vaginal microbiome was not altered significantly in GBS-colonized women, use of antibiotics had an effect on its composition.

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 and Objectives: Group B streptococcus (GBS) can cause severe and invasive infections in pregnant women, infants, and adults. This study aimed to investigate the risk factors of GBS colonization in pregnant women and determine the macrolide resistance and capsular type of isolates. Materials and Methods: In a cross-sectional study, a total of 200 pregnant women were screened for GBS colonization by phenotypic methods. Antibiotic susceptibility pattern of colonizing isolates and ermB, ermTR, mefA/E genes were detected. Also, molecular capsular types of isolates were distinguished. Results: The overall prevalence of colonization of participates with GBS was 13.5%. Statistical analysis showed that there was no association between risk factors and colonization with GBS. The highest resistance was observed to erythromycin (44.4%) followed by clindamycin (29.6%), penicillin, ampicillin, and ceftriaxone (18.5%), levofloxacin (11.1%), and 29.6% isolates were multidrug-resistant. ermTR and mefA/E genes were detected in 37% and 11.1% isolates; respectively and the ermB gene was not detected. The most common capsular type was type Ib (44.4%) followed by type III (40.7%), type II (11.1), and type Ia (3.7%). Conclusion: In the present study, the prevalence of GBS was in the medium range. Resistance to key antibiotic agents was relatively high. Also, capsular serotype Ib was the predominant serotype, which emphasizes the importance of monitoring the molecular typing of the GBS isolates regularly.

A hospital based cross sectional study was carried out to analyze prevalence of risk factors for stroke in hospitalized patient in a medical college hospital. 100 patients were chosen using purposive sampling technique. Highest incidence of stroke was between the 6th and 7th decade. Patients came from both urban (54%) and rural (46%) areas and most of them belong to the low-income group (47%). In occupational category; service holder (28%) and retired person (21%) were the highest groups. Most of the study subjects were literate (63%). CT scan study revealed that the incidence of ischaemic stroke was 61% and haemorrhagic stroke 39%. Analysis indicated hypertension as major risk factor for stroke (63%) and major portion of the patients (42.85%) were on irregular or no treatment. Twenty four percent of the patients had heart diseases and out of 24 patients 45.83% were suffering from ischaemic heart disease. The present study detected diabetes in 21% patients. Fifty three percent of the study subjects were smoker, 39% patients had habit of betelnut chewing. Out of 26 female patients, only 23% had history of using oral contraceptives. Majority of the patients were sedentary workers (46%). Thirty seven percent of the stroke patients were obese. Among the stroke patients 9% had previous history of stroke and 3% had TIA respectively. Most of the patients (21%) were awake while they suffered from stroke and the time of occurrence was mostly in the afternoon (46%). This study found that hypertension, cigarette smoking, ischaemic heart disease and diabetes mellitus are the major risk factors prevalent in our community while other risk factors demand further study.

Background: Hypertension and gestational diabetes are among the leading causes of maternal and perinatal mortality, especially in rural areas of developing countries with meager health facilities. With early diagnosis and timely treatment, these adverse events can be decreased. The primary aim of this study was to implement a screening program for gestational diabetes and hypertension, and to assess risk factors associated with these conditions among antenatal women in the rural area of the Gujarat province in India.Methods: A cross–sectional study was conducted at one of the rural areas of Gujarat province in India. Following a random  cluster sampling procedure, the village of Davas was selected. A multistage random sampling method was utilized, resulting in a sample of 346 antenatal women. Screening guidelines from the American Diabetes Association were followed for gestational diabetes screening.Results: The majority of antenatal mothers (55.50%) were between 21-25 years of age. 242 antenatal women were multigravida, and among them, 85.96% had institutional delivery at their last pregnancy. Of the total 346 women, 17.60% were prehypertensive. The prevalence of systolic hypertension was 1.40%, diastolic hypertension was 0.90%, and gestational diabetes was 1.73%.Conclusion: Socioeconomically upper class, a family history of hypertension, and BMI ≥ 25 were strong risk factors for hypertension during pregnancy and gestational diabetes. Health education should be made readily available to antenatal mothers by paramedical workers regarding symptoms of hypertension and gestational diabetes mellitus for early self identification.
