Abstract
The current study evaluates antibiotic susceptibility and Extended Spectrum β-Lactamase (ESBL) production of 557 Escherichia coli isolates obtained from clean catch midstream urine samples using VITEK 2 compact automated microbial identification system. Different classes of drugs were used to determine the Minimum inhibitory concentration (MIC). In our study, 50.45% of isolates were ESBL producers. There is a higher incidence of UTI in females (77.4%) than in males (22.6%). The isolates reveal a high percentage of resistance to antibiotics like nalidixic acid (89.59%), ampicillin (75.76%), ticarcillin (73.43%), cefalotin (67.68%), cefixime (65.17%), ciprofloxacin (58.35%) and ceftriaxone (56.37%). An increased susceptibility pattern was observed for the isolates against drug classes like fosfomycin (98.03%) and nitrofurantoin (91.02%). Among the isolates, 395 (70.91%) were classified as Multidrug-resistant organisms based on the resistance pattern observed against three or more classes of antibiotics. One of the isolates resistant to fluoroquinolones, penicillins, penicillins along with β-lactamase inhibitor, aminoglycosides, third-generation cephalosporins and carbapenems was subjected to Whole genome sequencing (WGS). WGS data revealed the isolate to be a high-risk clone ST410, which contains antimicrobial-resistance genes (blaTEM-1B, blaCTX-M-15, blaNDM-5, aac(3)-IId, armA, gyrA(p.S83L), gyrA(p.D87N)) conferring resistance to β-lactam, cephalosporins, carbapenem, aminoglycoside and fluoroquinolone class of antibiotics. The core genome MLST was carried out using BacWGSTdb to assess the global phylogenetic relationship of the genome sequence.

JAC Antimicrob Resist 2023; 5:dlad074. [PMID: 37305848 PMCID: PMC10251202 DOI: 10.1093/jacamr/dlad074] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Accepted: 05/26/2023] [Indexed: 06/13/2023] Open
Abstract
Introduction Antimicrobial resistance is a major public health issue worldwide and became one of the principal international healthcare crises of the 21st century. The production of ESBLs is one of the resistance mechanisms in Enterobacteriaceae, and they are increasingly detected in Escherichia coli and Klebsiella pneumoniae globally. Therefore, the aim of this study was to determine the phenotypic and molecular characteristics of ESBL-producing E. coli and K. pneumoniae among Lebanese patients. Methods A total of 152 ESBL-producing E. coli and K. pneumoniae were obtained from Geitaoui Hospital in Beirut between September 2019 and October 2020 from various clinical samples. The phenotype of ESBL producers was confirmed by a double-disc synergy test and antibiotic susceptibility was determined using the disc diffusion method. Genotypically, multiplex PCR was used to detect the ESBL genes (blaTEM, blaCTX-M and blaSHV). Results All strains were confirmed to be ESBL producers (121 isolates were E. coli and 31 isolates were K. pneumoniae). All isolates showed resistance to cefotaxime, cefuroxime, ampicillin and piperacillin. On the other hand, they showed a low susceptibility rate to trimethoprim/sulfamethoxazole and ciprofloxacin. Almost all the isolates were susceptible to ertapenem, imipenem and amikacin. In our study, ESBL genes were detected among 48 (39.67%) E. coli isolates and 8 (58.06%) K. pneumoniae isolates, and the most prevalent gene was blaTEM (25%), followed by blaCTX-M (19.08%) and blaSHV (16.45%). Conclusion Imipenem and ertapenem are the most effective drugs to treat ESBL producers. However, antibiotic stewardship programs must be implemented immediately to combat antibiotic resistance.

Extended-spectrum beta-lactamase-producing Enterobacteriaceae related urinary tract infection in adult cancer patients: a multicenter retrospective study, 2015-2019. BMC Infect Dis 2023; 23:129. [PMID: 36879210 PMCID: PMC9987039 DOI: 10.1186/s12879-023-08023-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2022] [Accepted: 01/23/2023] [Indexed: 03/08/2023] Open
Abstract
BACKGROUND The aim of this study was to investigate the prevalence and risk factors of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae related urinary tract infections (UTI) in adult cancer patients. METHODS We conducted a retrospective study of three cancer hospitals centered on Cancer Hospital of Chinese Academy of Medical Sciences from 2015 to 2019. The clinical characters, risk factors and antimicrobial susceptibility of ESBL-producing Enterobacteriaceae UTI in adult cancer patients were described and analyzed. RESULTS A total of 4967 specimens of UTI were evaluated, of which 909 were positive. After excluding multiple infection bacteria, non-conforming strains, inconsistent pathological information, no drug sensitivity test or medical records, 358 episodes remained. Among them, 160 episodes belonged to ESBL-producing Enterobacteriaceae, while 198 were classified into non-ESBL group. The prevalence of ESBL UTI circled around 39.73 to 53.03% for 5 years. Subgroup analysis by tumor type revealed that 62.5% of isolates from patients with urological tumors were ESBL positive. Multivariate analysis showed that tumor metastasis (OR 3.41, 95%CI 1.84-6.30), urological cancer (OR 2.96, 95%CI 1.34-6.53), indwelling catheter (OR 2.08, 95%CI 1.22-3.55) and surgery or invasive manipulation (OR 1.98, 95%CI 1.13-3.50) were the independent risk factors. According to antimicrobial sensitivity, meropenem, imipenem and piperacillin/tazobactam were the most commonly used antibiotics for ESBL-producing Enterobacteriaceae UTI. CONCLUSIONS In view of the high prevalence, clinicians should be alert to the occurrence of ESBL UTI, especially for patients with urological cancer or metastatic tumors. Regular replacement of urinary catheters, reduction of unnecessary invasive operations and selection of appropriate antibiotics are the necessary conditions to deal with the occurrence of ESBL UTI in adult cancer patients.

Abstract
Objective This systematic review and meta-analysis aimed to assess the pool estimates of extended-spectrum β-lactamases producing K. pneumoniae (ESBL-KP) and study their drug resistance profile by evaluating the studies from Nepal. Methods A literature search was carried out in PubMed, Google Scholar, and NepJOL to screen all articles on ESBL-KP published between 2011 and 2021 from Nepal. This review was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Relevant data were extracted, and R language 4.2.0 software was used for statistical analysis. Results The pooled prevalence of K. pneumoniae was 5%, while the pooled prevalence of ESBL and multidrug resistance (MDR) in K. pneumoniae were 23% and 55%, respectively. Imipenem was the drug of choice (in vitro) against ESBL-KP infection. Conclusion Our analyses showed a high prevalence of ESBL-KP and their high resistance toward commonly used drugs. This study highlights the need for the development of new antibiotics for the management of ESBL-KP infections.

Abstract
Background: Urinary tract infection (UTI) is among the most common infections occurring during childhood. It is caused by both gram-negative and gram-positive bacteria and Escherichia coli is the most common causative agent. Methods: Data of all pediatric patients in the age group of 6 months to 18 years with urinary tract infection were taken for analysis. Urine samples were collected and cultured on the cystine lactose electrolyte-deficient medium. The presence of bacteria was identified using biochemicals, and the antimicrobial test was performed using the Kirby-Bauer test or the VITEK 2 compact system (bioMérieux, Inc., France). Results: The prevalence of UTI was 23.5%. In total, 614 specimens tested positive with significant bacteriuria. The male-to-female ratio was 1:2.3. Approximately 54% patients presented with urinary symptoms alone. Culture positivity was significantly associated with pyuria (p < 0.0001). E. coli (334/614) was the most common isolate, followed by Enterococcus spp. (92/614). Colistin, polymyxin B, fosfomycin, nitrofurantoin, netilmicin, and amikacin were extremely good acting antimicrobials. Meanwhile, ampicillin, cefotaxime, ceftriaxone, and norfloxacin were highly resistant to gram-negative bacteria. Multidrug-resistant bacteria and extended-spectrum beta-lactamase-producing bacteria were found in 47% and 44.1% of cases, respectively. Vancomycin, linezolid, teicoplanin, and nitrofurantoin were highly effective against gram-positive bacteria. Furthermore, norfloxacin, trimethoprim/sulfamethoxazole, ciprofloxacin, and tetracycline were highly resistant to gram-positive bacteria. Of the 92, 42 Enterococcus spp. were resistant to high-dose gentamicin. Conclusion: Nitrofurantoin and amikacin can be used as empirical therapy for gram-negative and gram-positive bacteria. Because resistance to various commonly used antibiotics is found to be increasing, treatment must be guided by antibiotic susceptibility reports.

Abstract
Introduction Klebsiella species cause pneumonia, UTI, and septicemia in human beings. Beta-lactam drugs are used extensively to treat patients infected with Klebsiella, but most of the Klebsiella species are resistant to third- and fourth-generation cephalosporins and monobactams to which data are scarce in the study area. Objective To determine the prevalence, antimicrobial resistance, ESBL production, and associated risk factors of Klebsiella species among UTI-suspected patients in Bahir Dar City, Northwest Ethiopia. Methods A multi-institution-based prospective cross-sectional study was conducted from January to May 2019. Midstream urines were collected from 385 patients and inoculated onto CLED and MacConkey agars. Identification of growth was done by a battery of biochemical tests. Antimicrobial resistance and ESBL production patterns were determined by using the disc-diffusion method on Mueller–Hinton agar. Quality of data was maintained by following SOPs and using Klebsiella pneumoniae (ACTT700603). Logistic regression statistical analysis was done using the SPSS, version 25, statistical package. A pvalue ≤ 0.05 was considered statistically significant. Results The median age of the study participants was 32 years. Majority of them were female, urban residents, and unable to read and/or write. The total Klebsiella species detected were 38 (9.9%). Of which, 25 (65.8%) were Klebsiella pneumoniae, followed by 6 (15.8%) Klebsiella ozaenae. 20 (80%), 19 (76%), and 19 (76%) Klebsiella pneumoniae showed resistance to amoxicillin/clavulanic acid, ampicillin, and cotrimoxazole, respectively. All K. oxytoca were resistant to ampicillin, and all K. rhinoscleromatis were resistant to cefoxitin and cefotaxime. Klebsiella species that showed resistance to ≥3 antimicrobials were 26 (68%). ESBL-producing Klebsiella species were 10 (26.3%). Patients who had history of antibiotic use, hospitalization, and tight dressing habit had more risk of getting UTI (p < 0.05) than their counterparts. Conclusions Overall UTI prevalence in our study was lower than that of previous Ethiopian studies. High MDR and ESBL-producing Klebsiella species were detected. Patients' history of antibiotic use, hospitalization, and tight dressing habit were risk factors for UTI. It calls up for improving prevention/control systems of Klebsiella species.

Abstract
Urinary tract infections caused by extended-spectrum β-lactamase Escherichia coli (ESBL-EC) are increasing worldwide and are a current concern because treatment options are often limited. This study investigated antimicrobial susceptibility, antimicrobial resistance genes (ARGs), and the biological diversity of urinary ESBL-EC isolates at Cerdanya Hospital, a European cross-border hospital that combines French and Spanish healthcare models. Bacterial identification and susceptibility were determined using the Microscan WalkAway® system and ESBL production was examined by the double-disk synergy method. Isolates were sequenced using the Ion S5™ next-generation sequencing system, with the whole-genome sequences then assembled using SPADEs software and analyzed using PubMLST, ResFinder, FimTyper, PlasmidFinder, and VirulenceFinder. A phylogenetic analysis was performed by constructing an assembly-based core-SNV alignment, followed by a phylogenetic tree constructed using Parsnp from the Harvest suite. All isolates studied were multidrug-resistant and could be classified into 19 different sequence types characterized by a high genetic diversity. The most prevalent ESBL-enzymes were CTX-M-14 and CTX-M-15. High-risk international clones (ST131, ST10, and ST405) were also identified. The results demonstrated the absence of a single predominant clone of ESBL-MDR-EC at Cerdanya Hospital.

Abstract
Introduction Urinary tract infection (UTI) is one of the most common infections in clinical practice worldwide in both healthcare and community settings causing significant morbidity and mortality. It is one of the major conditions at the community level treated empirically and regarded as a potential cause of emergence of antimicrobial resistance (AMR). Limited information is available regarding community-acquired UTI (CA-UTI) from India. Methodology This is a first of its kind, multicentric-cross-sectional study at the community level targeting patients attending the out-patient department (OPD) of the community health centre (CHC) from four geographical regions (North, South, West and East) of India. The study had been designed to determine the epidemiology, antibiogram profile and identification of extended-spectrum beta-lactamase (ESBL) producer and carbapenem resistant (CR) uropathogens. Samples were collected prospectively from UTI suspected patients coming at CHC and processed at the tertiary healthcare centres using a common standard operating procedure. Clinical history of all the patients exhibiting significant bacteriuria was collected and data was analysed. Result Overall, 250 out of a total of 2459 (10.1 %) urine samples were positive for bacteria with significant bacteriuria (adult: paediatrics, 6.7 : 1). Females were predominantly affected (male: female, 1 : 2.9). History of recent episode of UTI was observed as the commonest risk factor followed by diabetes mellitus. Altogether, 86 % of total cases were caused by Escherichia coli (68 %) and Klebsiella pneumoniae (17.6 %) together. Among the commonly used oral antibiotics for the Gram-negative bacilli (GNB), the highest resistance was observed against beta-lactams, first- and second-generation cephalosporins, fluoroquinolones and co-trimoxazole. Overall, the prevalence of ESBL producer and CR isolates were 44.8, and 4.3 %, respectively. However, the ESBL production, CR and nitrofurantoin resistance among the uropathogenic E. coli (UPEC) isolates was 52.8, 5.1 and 14 %, respectively. No resistance was found against fosfomycin among the UPEC isolates. Conclusion The current study highlights the increasing incidence of AMR among uropathogens at the community-settings of India. A significant percentage of ESBL producers among the isolated UPEC and K. pneumoniae were observed. The currently available evidence supports the clinical recommendation of fosfomycin and nitrofurantoin for empiric therapy in CA-UTI in India.

Abstract
Urinary tract infections (UTI) are one of the most common indications for antibiotic prescriptions in the outpatient setting. Given rising rates of antibiotic resistance among uropathogens, antibiotic stewardship is critically needed to improve outpatient antibiotic use, including in outpatient clinics (primary care and specialty clinics) and emergency departments. Outpatient clinics are in general a neglected practice area in antibiotic stewardship programs, yet most antibiotic use in the United States is in the outpatient setting. This article provides a comprehensive review of antibiotic stewardship strategies for outpatient UTI in the adult population, with a focus on the "five Ds" of stewardship for UTI, including right diagnosis, right drug, right dose, right duration, and de-escalation. Stewardship interventions that have shown success for improving prescribing for outpatient UTI are discussed, including diagnostic stewardship strategies, such as reflex urine cultures, computerized decision support systems, and modified reporting of urine culture results. Among the many challenges to achieving stewardship for UTI in the outpatient setting, some of the most important are diagnostic uncertainty, increasing antibiotic resistance, limitations of guidelines, and time constraints of stewardship personnel and front-line providers. This article presents a stewardship framework, built on current evidence and expert opinion, that clinicians can use to guide their own outpatient management of UTI.

Abstract
Background In 2018 Pakistan initiated its national antimicrobial resistance (AMR) surveillance aligned with Global Antimicrobial Surveillance System (GLASS). To complement this surveillance, we conducted a situational analysis of AMR rates among GLASS organisms in the country. Data from published studies and from antibiograms was compared and role of antibiograms as potential contributors to national AMR surveillance explored. Methods AMR rates for GLASS specified pathogen/antimicrobials combination from Pakistan were reviewed. Data sources included published studies (2006–2018) providing AMR rates from Pakistan (n = 54) as well as antibiograms (2011–2018) available on the Pakistan Antimicrobial Resistance Network (PARN) website. Resistance rates were categorized as follows: Very low: 0–10%, Low: 11–30%, Moderate: 30–50% and High: > 50%. Results Published data from hospital and community/laboratory-based studies report resistance rates of > 50% and 30–50% respectively to 3rd generation cephalosporins, fluoroquinolones and cotrimoxazole amongst Klebsiella pneumoniae and Escherichia coli. Carbapenem resistance rates amongst these organisms remained below 30%. High (> 50%) resistance was reported in Acinetobacter species to aminoglycosides and carbapenems among hospitalized patients. The evolution of ceftriaxone resistant Salmonella Typhi and Shigella species is reported. The data showed > 50% to fluoroquinolones amongst Neisseria gonorrhoeae and the spread of methicillin resistant Staphylococcus aureus (< 30%; 2008) to (> 50%; 2010) in hospital settings. Resistance reported in published studies aligned well with antibiogram data. The latter also captured a clear picture of evolution of resistance over the study period. Conclusion Both published studies as well antibiograms suggest high rates of AMR in Pakistan. Antibiogram data demonstrating steady increase in AMR highlight its potential role towards supplementing national AMR surveillance efforts particularly in settings where reach of national surveillance may be limited.

[PMID: 34107556 DOI: 10.1111/ijcp.14475] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/05/2021] [Revised: 05/05/2021] [Accepted: 05/11/2021] [Indexed: 11/28/2022] Open
Abstract
AIM OF STUDY Urinary tract infections (UTIs) are among the most common infections affecting individuals of different ages worldwide. Antimicrobial agents are usually the first-line treatment for UTIs, and the use of the prescribed antibiotic is escalating, resulting in increased rates of bacterial resistance and UTI recurrence. The current study aimed to identify the causative bacteria in Jordan, to explore their resistance pattern to antibiotics and to describe drug-related problems (DRPs) associated with UTI management. METHODS This prospective, descriptive study was conducted in two major health institutions in two cities in Jordan over a period of six months. The study population included inpatients and outpatients diagnosed with UTIs. Patients' data were collected directly from patients using data collection sheet and from patients' charts. RESULTS A total of 273 patients were included, of whom 56.4% were women. Urine cultures were obtained from 81% of the patients. Escherichia coli was the most common causative pathogen (50.6%), followed by Klebsiella pneumonia (10.8%). Extended spectrum beta-lactamase (ESBL) producing E. coli was the most commonly detected organism across all types of UTIs. Ceftriaxone and imipenem/cilastatin were most commonly administered to hospitalised patients, whilst ciprofloxacin and co-triamzaxole were the most commonly prescribed in outpatient clinics. The susceptibility results for parenteral antibiotics showed high rates of resistance to cefazolin and ticarcillin. Additionally, high rates of resistance to fluoroquinolones were identified. Further, several DRPs were identified. High rates of resistance to commonly prescribed antibiotics were detected. DRPs (ie, inappropriate antibiotic dosage, unnecessary antibiotic prescribing, inappropriate duration of therapy and prescribing of ineffective antibiotics) were relatively common. CONCLUSION The present study highlights the need for clinical pharmacists to manage the high level of drug related problems by providing updated information about proper drug selection, rational drug use and patient education and counselling.

Abstract
Urinary tract infection (UTI) is regarded one of the most frequent bacterial infections in women. Accordingly, the aim of the current study was to determine the prevalence of extended-spectrum beta-lactamase (ESBL), as well as the degree of antimicrobial resistance among premenopausal (n = 44) and postmenopausal (n = 49) women suffering from uncomplicated UTI. Urinary samples (n = 93) collected from women with UTI were tested for their antimicrobial sensitivity and assessed for ESBL production by both phenotypic and genotypic methods. Phenotypically, the presence of ESBL was observed in 64 isolates, while polymerase chain reaction detected ESBL-encoding genes in 57 isolates. The CTX-M gene was the most predominant (51.6%), followed by TEM (46.2%), and the SHV gene (17.2%). Surprisingly, all ESBL-producing Escherichia coli isolates were multidrug-resistant (MDR). To the best of our knowledge, this is the first study conducted in Egypt showing significant correlation between ESBL production, multidrug resistance and menopausal state in women. The results demonstrate alarming signal for the dissemination of ESBL genes among uropathogenic E. coli that are MDR in Egypt.

Abstract
OBJECTIVES The prevalence of ESBL-producing Escherichia coli (ESBL-E. coli) in community-acquired urinary tract infections (UTI) has been increasing worldwide since 2000, but with large geographical variations. The aim of this study was to determine whether the ESBL-E. coli rate in urine samples from individuals with community-acquired UTI was associated with the local socio-economic, environmental, agricultural and healthcare characteristics. METHODS This was a cross-sectional study in western France using data on antibiotic susceptibility of E. coli isolated from urine samples of individuals with community-acquired UTI analysed in non-hospital laboratories from 2015 to 2017. The ESBL-E. coli rate was calculated for each laboratory. Data on socio-economic characteristics, human antibiotic consumption, hospital bed density, animal farming density and percentage of agricultural land and surface water were retrieved at the municipality level and aggregated by study area. Their association with ESBL-E. coli prevalence was quantified using multivariate linear regression models with a backward selection. RESULTS From 358 291 E. coli isolates from urine samples tested in 92 laboratories, the mean ESBL-E. coli prevalence for the study period was 3.30%. In an adjusted model, the ESBL-E. coli rate was significantly (P < 0.05) and positively associated with the local percentage of people >65 years old, third-generation cephalosporin use (DDD/1000 inhabitants), number of hospital beds/km2, poultry density, pig density and percentage of agricultural land. Lower deprivation was associated with a higher ESBL-E. coli rate. CONCLUSIONS Several anthropogenic factors (primary care, hospitals and animal farming) are associated with the local ESBL-E. coli rate in community-acquired UTI. These results could contribute to improve risk management, including identification of at-risk patient groups.

Abstract
Background and aim Gram-negative rods (GNR) are the most common pathogens associated with urinary tract infections (UTI). The resistance of these gram-negative rods to various antibiotics is increasing with time. The study aimed to determine the pattern of resistance to antibiotics in GNR causing urinary tract infection in adults. Material and methods This is a cross-sectional study conducted during six months (1st December 2019 to 1st June 2020) among adult patients admitted to Russells Hall Hospital Dudley, UK. Urine cultures of 156 patients admitted with urinary tract infection were collected and reviewed. Sources of urine included midstream urine (MSU), catheter specimen urine (CSU), and others from nephrostomy bags and urine bags. Sensitivity and resistance were checked using Clinical and Laboratory Standards Institute (CLSI) guidelines. Results were analyzed using SPSS version 13. Results Altogether 156 patients were included in the study. Males were 40.4% of the patients were males, and 59.6% were females. The mean age was 78 with a standard deviation (SD) of 13.15. Most of the samples (67.3%) were urine MSU, 23.1% catheter urine, and 9.6% were others, like from nephrostomy bags or unspecified. Resistance to amoxicillin was found in 61.7%, trimethoprim in 36.2%, nitrofurantoin in 13.2%, ciprofloxacin in 25.6%, fosfomycin in 10.7%, co-amoxiclav in 36.2%, gentamicin in 12.8%, piperacillin-tazobactam in 7.1%, cephalexin in 44.4%, and meropenem in 0% of patients. Conclusion Resistance to gram-negative rods causing urinary tract infection is increasing; a particular concern is increased resistance to beta-lactams, trimethoprim, and quinolones.

Abstract
Nowadays, increasing extended-spectrum β-lactamase (ESBL)-producing bacteria have become a global concern because of inducing resistance toward most of the antimicrobial classes and making the treatment difficult. In order to achieve an appropriate treatment option, identification of the prevalent species which generate ESBL as well as their antibiotic susceptibility pattern is essential worldwide. Hence, this study aimed to investigate the prevalence of ESBL-producing bacteria and assess their drug susceptibility in Fardis Town, Iran. A total of 21,604 urine samples collected from patients suspected to have urinary tract infection (UTI) were processed in the current study. The antimicrobial susceptibility of the isolates was tested by the disk diffusion method. The ESBL producing bacteria were determined by Double Disc Synergy Test (DDST) procedure. Bacterial growth was detected in 1408 (6.52%) cases. The most common bacterial strains causing UTI were found E. coli (72.16%), followed by K. pneumoniae (10.3%) and S. agalactiae (5.7%). Overall, 398 (28.26%) were ESBL producer. The highest ESBL production was observed in E. coli, followed by Klebsiella species. ESBL producers revealed a higher level of antibiotic resistance compared with non-ESBLs. In conclusion, ESBL production in uropathogens was relatively high. Carbapenems and Aminoglycosides were confirmed as the most effective treatment options for these bacteria.

Abstract
Urinary tract infection (UTI) is one of the most common complaints in the outpatient clinic and a major health problem owing to the emergence of antibiotic resistance and biofilm formation. The objective of this study was to isolate and identify the causative bacterial agent of UTI and detect in vitro biofilm formation by Escherichia coli and investigate its correlation with antibiotic resistance. Urine samples from 519 patients with suspected UTIs were collected and processed by conventional microbiological procedures. Antimicrobial susceptibility testing for E. coli isolates was performed on Mueller Hinton agar (MHA) plates using the Kirby-Bauer disk diffusion method. Biofilm production was evaluated using the tissue culture plate method. Of 519 urine samples, 115 (22.1%) showed significant bacteriuria. The most common isolate was E. coli (n=57, 49.6%), followed by Klebsiella spp. (n=23, 20%). All E. coli isolates were evaluated for their ability to form biofilms in vitro. Of 57 isolates, 50 (87.7%) were biofilm producers and 7 (12.3%) were non-biofilm producers. Antibiogram of E. coli isolates revealed the highest resistance to ampicillin (96.5%) and nitrofurantoin (91.2%), followed by amoxyclav (82.5%), ceftazidime (73.7%), cefepime (71.9%), and tetracycline (71.9%). A significant association (p<0.05) was observed between biofilm formation and resistance to amoxyclav, ceftazidime, cefepime, imipenem, and nitrofurantoin. A significant correlation was noted between biofilm production and antibiotic resistance. Hence, screening of all isolates of uropathogenic E. coli for biofilm production and studying their antibiogram would allow appropriate choice of antibiotic therapy.

Abstract
Purpose The prevalence of extended-spectrum beta-lactamase-producing Escherichia coli (ESBL-EC) has been increasing worldwide since the early 2000s. E. coli is found in 70–90% of community-acquired urinary tract infections (CA-UTIs). We performed a systematic literature review to determine the risk factors for CA-UTI caused by ESBL-EC. Methods We searched the MEDLINE, Cochrane Library, Embase and Web of Science databases without language or date restriction up to March 2019. Two independent reviewers selected studies with quantified risk factors for CA-UTI due to ESBL-EC, and assessed their quality using the Newcastle-Ottawa Scale. Results Among the 5,597 studies identified, 16 observational studies (n=12,138 patients) met the eligibility criteria. The included studies were performed in various countries, and 14/16 were published after 2012. The most relevant risk factors for CA-UTI due to ESBL-EC identified were prior use of antibiotics (odds ratio (OR) from 2.2 to 21.4), previous hospitalization (OR: 1.7 to 3.9), and UTI history (OR: 1.3 to 3.8). Two risk factors were related to environmental contamination: travelling abroad, and swimming in freshwater. Conclusion Our findings could allow adapting empiric antibiotic treatments according to the patient profile. Further studies are needed to quantify the relationships between CA-UTI due to ESBL-EC and the environment.

Abstract
Background Increasing prevalence of community-acquired infections (CAIs) due to Escherichia coli and Klebsiella pneumoniae producing extended-spectrum beta-lactamase (ESBL), especially the Cefotaxime-Munich (CTX-M) type, carbapenemase, and New Delhi metallo-β-lactamase (NDM), has been reported globally posing a serious public health threat that has complicated treatment strategies for Gram-negative bacterial infections. While most of the reports in this regard are based on hospitalized patients from the urban community, there is a paucity of data in a rural community presenting with CAIs. Materials and Methods A total of 1275 strains of E. coli and K. pneumoniae isolated over a period of 3 years from patients with CAIs were subjected to the detection of ESBL by double-disc synergy test; carbapenemase by modified Hodge test; metallo-β-lactamase by MIC test strip metallo-β-lactamase (MBL); and bla TEM, bla SHV, bla CTX-M, and bla NDM genes by polymerase chain reaction. Results Among 1275 E. coli and K. pneumoniae isolated during the study period, 773 (60.6%), 102 (8%), and 28 (2.2%) isolates were detected as ESBL, carbapenemase and MBL producers, respectively. Of the 773 ESBL producers, 635 (82.1%) were found to harbor bla CTX-M genes, and of the 102 carbapenemase producers, 12 (11.8%) were found to harbor bla NDM genes. Gene sequencing of all the 12 NDM-positive isolates revealed bla NDM-1 genes. Antibiotic resistance pattern of the ESBL-positive isolates revealed a high degree of co-resistance to noncephalosporin antibiotics such as amoxyclav, co-trimoxazole, chloramphenicol, and fluoroquinolones. Conclusion The present study showed the increasing the prevalence of ESBL including CTX-M variety, carbapenemase production by E. coli and K. pneumoniae isolates, and spread of NDM-1 in the patients from the rural community of North India.

Abstract
Background Urinary tract infection (UTI) is one of most common pediatric infections. The study was designed to assess the clinical profile, common bacterial microorganisms causing UTI and their antimicrobial susceptibility patterns at B. P. Koirala Institute of Health Sciences (BPKIHS) hospital. Methods This is a prospective cross-sectional study conducted at Department of Microbiology and Infectious Diseases for 6 months (January to June 2018). A total of 1962 non-repetitive urine specimens (midstream, nappy pad, catheter aspirated) of pediatric patients (0–14 years age) suspected of UTI were obtained in the Microbiology laboratory. Clinical data was obtained from requisition form and hospital software. Culture and bacterial identification was done by using standard microbiological guidelines. Antimicrobial susceptibility testing was done by Kirby-Bauer disc diffusion method following clinical and laboratory standards institute (CLSI) guidelines. Resistance to methicillin and vancomycin were confirmed by calculating minimum inhibitory concentration using broth dilution method. Results Among 1962 samples, 314 (16%) were positive for bacterial infection. Fever, irritability and poor feeding was the most common symptoms in neonates while older children presented with fever and urinary symptoms. E. coli was reported the most common etiological agent (53%), followed by Enterococcus faecalis (22%), Klebsiella pneumoniae (7%) and Staphylococcus aureus (7%). Multidrug resistant (MDR) isolates accounted for 32% of isolates, while 5% were extensively drug resistant (XDR). Fourty percentage of gram-negative bacilli were ESBL producer, 38% of S. aureus were methicillin resistant Staphylococcus aureus (MRSA) and 5% E. faecalis were vacomycin resistant enterococci (VRE). E coli was highly resistant to Ampicillin (87%), Ceftriaxone (62%) and Ofloxacin (62%). Amikacin (11% resistance) and Nitrofurantoin (5% resistance) are the most effective drugs for gram-negative bacilli (GNB) while vancomycin and linezolid are functional against gram-positive cocci. Conclusions High-level antimicrobial resistance was observed in pediatric UTI with alarming incidence superbugs like MDR, XDR, ESBL and MRSA. Regular surveillance should be carried out to determine the local prevalence of organisms and antimicrobial susceptibilities in order to guide the proper management of children.
