Significant Bacteriuria

INTRODUCTION Urinary tract of female undergoes tremendous changes during pregnancy which increases their risk of acquiring infection. Asymptomatic bacteriuria is a common entity among pregnant women which refers to significant bacteriuria (>105 bacteria per ml of urine) without any typical symptoms of urinary tract infection. Asymptomatic bacteriuria can lead to various maternal and fetal complications if not detected and treated on time. MATERIAL AND METHODS Total 280 urine samples were collected in sterile universal containers from pregnant women not showing typical symptoms of urinary tract infection at the time of sample collection. Urine samples were inoculated in both MacConkey agar and Blood agar by semi quantitative culture method. Culture plates were reported after 24 hours of incubation at 370C. Bacteria isolated were subjected to antibacterial susceptibility testing by modified Kirby-Bauer disc diffusion method. RESULTS Out of 280 urine cultures, 213 samples were sterile. Significant bacteriuria was seen in 25 cases (8.9%) followed by insignificant bacteriuria (20, 7.14%) and contamination (17, 6.10%). Highest number of cultures positive were in age group 21-30 years (19, 9.1%,). Out of 25 cases of significant bacteriuria, 60% were primigravida and 40% were multigravida. The most common organism isolated was Escherichia coli (10, 60%) followed by Klebsiella pneumoniae (5, 40%). CONCLUSION Screening of all pregnant women for asymptomatic bacteriuria is essential during their antenatal checkup. Escherichia coli is the commonest organism that cause asymptomatic bacteriuria. Appropriate antibiotic therapy is absolutely necessary for positive cases on the basis of antimicrobial susceptibility result to prevent unwanted obstetric complications.

Background: Urinary tract infection is caused by the presence and replication of microorganisms in the urinary tract. Urinary tract infection is a major health problem among females especially among pregnant women and this is caused by the physiological makeup of the female urinary tract. Objective: This study was designed to assess the epidemiology of UTIs present amidst pregnant women and females residing in the Omu-Aran community. Materials and Methods: A total of 100 individuals were involved of which 50 were pregnant women while the remaining 50 were non-pregnant females. Semi-structured questionnaires were distributed to all participants to obtain their data. Samples of urine (early morning midstream) were collected in universal bottles from participants. The urine specimens were cultured on four different agar plates which were; cystein lactose electrolyte deficient agar, blood agar, MacConkey agar and nutrient agar for significant bacteria growth. Microscopic and macroscopic examination was also carried out on the samples for possible detection of infections. Results: The result of the culture showed a significant bacterial growth of 77% and 23% of the samples collected showed no significant bacterial growth. Bacteria such as Escherichia coli, Klebsiella pneumoniae, Staphylococcus spp., Proteus species, Pseudomonas aeruginosa and Candida albicans were isolated. With Staphylococcus aureus predominantly present and observed as the causative factor for (45.4%) occurrence of UTIs, closely followed by Staphylococcus saprophyticus (13.0%), Escherichia coli (13.0%), Klebsiella pneumoniae (9.1%) Proteus species (9.1%), Staphylococcus epidermidis (7.8%) and Pseudomonas aeruginosa (1.3%). However the only fungi isolated was Candida albicans showing (1.3%) prevalence, Candida is the most common cause of fungal infections in humans. Conclusion: Results obtained in this work showed a high prevalence of Urinary tract infection at our study location. A prompt enlightenment campaign and need for periodic check among females is highly advocated to reduce or out rightly eliminate the spread of common uropathogens in circulation.

Extended-spectrum β-lactamases producing Escherichia coli (ESBL-EC) lend resistance to most β-lactam antibiotics. Because of limited treatment options, ESBL-EC infections are generally more difficult to treat, leading to higher hospital costs, reduced rates of microbiological and clinical responses, and a threat to the patient’s life. This study aimed to determine the antibiotic resistance pattern of ESBL-EC isolated from patients with urinary tract infection in Morocco. This retrospective laboratory-based study was conducted at Cheikh Khalifa International University Hospital, Casablanca, from January 2016 to June 2019. A total of 670 urine samples were collected from urinary tract infection patients and processed by standard microbiological methods. In vitro susceptibility testing to different antibiotics of all identified isolates of Escherichia coli (E. coli) was performed following Kirby–Bauer’s disc diffusion method on Mueller–Hinton Agar according to the EUCAST standards. The reviewing of ESBL-EC was confirmed by the appearance of a characteristically shaped zone referred to as a “champagne cork” using the Combined Disk Test. Among a total of 438 E. coli isolated from nonrepetitive urine samples, two hundred fifty-nine (59%) were ESBL-EC, of which 200 (77%) were isolated from adult patients (over the age of 50) and the majority were female. All ESBL-EC isolates were resistant to third-generation cephalosporin and quinolones and sensitive to carbapenem and fosfomycin. Knowledge of antimicrobial resistance patterns in ESBL-EC, the major pathogen associated with urinary tract infection, is indispensable as a guide in choosing empirical antimicrobial treatment.

Abstract Objectives:To investigate the role of microscopic examination of urine sample in supporting early diagnosis of asymptomatic urinary tract infection (UTI) in pregnant women. To compare correspondence between microscopic examination and urine culture result as a gold standard diagnostic modality to support the diagnosis of UTIs and as an evidence-based to start empirical therapy. Methods: Microscopic analysis was conducted in 74 centrifuged and non-centrifuged urine samples from 317 pregnant who came to six healthcare centres in Jakarta, which showed a positive result of nitrite examination.  The results of the microscopic examination of bacteriuria and leukocyturia were compared with a urine culture. Results: Sensitivity of centrifuged bacteriuria was the highest among the other microscopic parameters, which was 74% with the p-value of 0.009. Combination of bacteriuria and leukocyturia≥3/HPF dan≥5/HPF have increased the specificity with the value of 91.5% and 93.6% in non-centrifuged urine. Conclusion: This result showed that the best method of microscopic examination for early diagnosis of asymptomatic urinary tract infection in pregnant women is the detection of bacteriuria in centrifuged urine. Combination of bacteriuriaandleukocyturiatest, as well as leukocyturia≥3/HPF and≥5/HPF,  can be used to rule out the diagnosis of UTI at an early stage. Keywords: asymptomatic urinary tract infection, bacteriuria, leukocyturia,microscopic examination, urine culture.   Abstrak Tujuan: Mengetahui peran pemeriksaan mikroskopis sampel urin dalam mendukung diagnosis dini infeksi saluran kemih asimptomatik (ISK) pada perempuan hamil.

BACKGROUND The commonest bacterial agent involved in causation of urinary tract infection (UTI) is Escherichia coli, both in the community as well as in the hospital. In this study Escherichia coli strains isolated from patients with UTI were studied especially for extended spectrum beta-lactamase (ESBL) production and determination of fluoroquinolone resistance. METHODS This descriptive study was conducted in the Department of Microbiology, Katihar Medical College and Hospital from December 2018 to May 2020. Urine samples from suspected UTI cases were processed and bacterial isolates were identified as per standard protocol. Antimicrobial susceptibility testing was done by Kirby-Bauer discdiffusion method on Mueller-Hinton agar. ESBL detection was done as per Clinical and Laboratory Standards Institute (CLSI) guidelines. RESULTS Out of 3938 urine samples received in the microbiology laboratory, 708 samples showed significant growth of various bacteria and candida species, out of these only 105 patients had urinary tract infection caused by Escherichia coli. The male to female ratio was 0.25:1. Isolates were highly sensitive to nitrofurantoin (80.9 %) followed by amikacin (72.4 %) and imipenem (71.5 %). Maximum resistance was seen with amoxicillin (98.1 %), cefuroxime (96.2 %), cefpodoxime and cefotaxime (90.5 %), ceftriaxone (85.7 %), nalidixic acid (91.4 %) and ciprofloxacin (70.5 %). 70.5 % were found to be ESBL producers and 29.5 % were non-ESBL producers. The double disc synergy test (DDST) could detect only 42.8 % of ESBL producers whereas phenotypic confirmatory disc diffusion (PCDDT) detected 70.5 % of ESBL producers. CONCLUSIONS It was seen in the present study that a high proportion of community acquired strains of Escherichia coli were ESBL producers. In this study, 70.5 % of Escherichia coli strains were ESBL positive. It can therefore be recommended that all gram-negative isolates be tested for ESBL production preferably by the PCDDT test as this test was found to be most sensitive for detection of ESBL production. The PCDDT test requires minimum laboratory infrastructure, is cheap and easy as compared to molecular methods. KEY WORDS Escherichia coli, UTI, ESBL, PCDDT, DDST

Out of 200 urine samples of female out patients from BSMMU hospital, 128 (64%) cases were detected as Escherichia coli positive, 66.67% of cases in summer and 60% in winter. To compare the risks of E. coli infection in summer and winter and also among different age groups, odd ratio (OR) and relative risk (RR) were used as measures of comparative likelihood. The values of both OR and RR were greater than one when the risk of E. coli infection of adults (16-35) was compared with that of middle age (36-50) and old age (51-70) groups. The adults were always at higher risk of UTI by E. coli, and the livelihood of infection was not equal in summer and winter. DOI: http://dx.doi.org/10.3329/bjz.v40i2.14317 Bangladesh J.

Significant Bacteriuria

Abstract Background: Urinary tract infection is caused by bacteria from the digestive tract which climbs the opening of the urethra and begins to multiply to cause infection. This study aimed to assess the bacterial profile and antibiotic susceptibility pattern and associated risk factors among pregnant women in Madda Walabu University Goba Referral Hospital, Southeast Ethiopia. Methods: An institution-based cross-sectional study was conducted from June-August, 2019. A total of 234 pregnant women were enrolled; data were collected using a structured questionnaire by a trained interviewer. Urine samples were collected from all pregnant women and culture on cysteine lysine electrolytes deficiency medium. Data were analyzed using SPSS 20.0. Descriptive statistics were used to explain the study participants with relevant variables. Logistic regression was used for data comparison. P-value <0.05 was accepted as statistically significant. Results: The overall prevalence of UTI was 23.9% among both asymptomatic and symptomatic groups. Of this screened midstream urine samples showed that 16% and 32.2%, had significant bacteriuria in the asymptomatic and symptomatic groups respectively. The prevalence of UTI was significantly associated with previous history of catheterization and urinary tract infection. E. coli was the most frequently isolated organism (42.9%) followed by coagulase-negative Staphylococcus (26.8%), and S. aureus (12.5%). Gram-negative and Gram-positive bacteria accounted for (59%) and (41%) respectively.Conclusion: Significant bacteriuria has been observed from both symptomatic and asymptomatic pregnant women. The majority of the isolates were resistant to commonly prescribed antibiotics. This calls for an early screening of all pregnant women for UTI and those found to be infected need treatment.
