Abstract Objective This study was aimed to determine prevalence and resistance pattern like multidrug resistant (MDR) or ESBL nature of E. coli and Klebsiella spp. from various sewage drain samples with an idea to deliver baseline information that could be utilized for defining guidelines for the treatment of hospital sewages. Results Of 10 sewage samples analyzed, 7 (70%) contained E. coli while 6 (60%) contained Klebsiella. Except one sample, all positive samples contained both E. coli and Klebsiella spp. E. coli isolates were resistant to ampicillin, amoxicillin, cefoxitin, cefuroxime, and cefpodoxime; while 85.7% were resistant to amoxicillin/clavulanate, ceftazidime, cefotaxime and ceftriaxone. 71.4%, 57.1%, 42.9%, and 28.6% were resistant to aztreonam, trimethoprim/sulfamethoxazole, nitrofurantoin, and gentamicin. Most were sensitive to chloramphenicol, ofloxacin, ciprofloxacin, and azithromycin. 85.7% and 57.1% of E. coli were MDR and ESBL isolates, respectively. Klebsiella were resistant to ampicillin, amoxicillin, and amoxicillin/clavulanate. 83.4% of Klebsiella were resistant to cefoxitin. 66.7% of strains were resistant to cefuroxime, ceftazidime, cefotaxime, ceftriaxone, and cefpodoxime. Klebsiella showed 50% resistant to aztreonam and trimethoprim/sulfamethoxazole, while 33.3% were resistant to chloramphenicol, nitrofurantoin, ofloxacin, and ciprofloxacin. Klebsiella were sensitive to azithromycin and gentamicin. 66.7% and 33.3% of Klebsiella were MDR and ESBL isolates, respectively.

Aims: This study investigates and reports the production of extended spectrum beta-lactamase in Escherichia coli isolates in poultry droppings sourced from selected poultry farms in Karu, Nigeria Study Design:  Cross sectional study Place and Duration of Study: Department of Microbiology, Nasarawa State University, Keffi, between August 2019 and February 2020. Methodology: Escherichia coli was isolated from the samples using standard cultural and microbiological methods. Antibiotic susceptibility testing and minimum inhibitory concentrations were evaluated as described by the Clinical and Laboratory Standards Institute (CLSI). The detection of ESBL production in E. coli isolates was carried out using double disc synergy test.  In addition, molecular detection of ESBL genes was carried out using Polymerase Chain Reaction (PCR) method. Results: All (100%) samples collected had E. coli. Antibiotic resistances in the isolates in decreasing order were as follows: ampicillin (96.7%), streptomycin (94.4%), sulphamethoxazole /trimethoprim (87.8%), amoxicillin/ clavulanic acid (61.1%), gentamicin (52.2%), ciprofloxacin (40.0%), ceftazidime (35.6%), cefotaxime (31.1%), imipenems (22.2%), cefoxitin (13.3%). The commonest antibiotic resistant phenotype was AMP-SXT-S-CTX-CN (8.8%). Multiple antibiotic resistance (MAR) was observed in 92.2% (83/90) of the isolates with the common MAR indices being 0.5 (26.5%), 0.6 (19.2%), 0.4 (13.2%) and 0.9 (10.8%). Fifty nine of the eighty beta-lactam resistant isolates (73.7%) were confirmed ESBL producers. 55 of the 59 ESBL positive isolates (93.2%) carried bla genes as follows:   blaSHV (50/55, 90.9%), blaTEM (31/55, 56.3%) and blaCTX-M (46/55, 83.6%). Thirty six (65.5%) of the 55 isolates carried two bla genes (blaSHV and blaTEM, blaTEM and blaCTX-M, and blaCTX-M and blaSHV). Conclusion: The E. coli isolates showed lower resistances to cefoxitin, imipenem, cefotaxime, ceftazidime, and ciprofloxacin and most isolates were MAR, with resistance to 5 antibiotics being the most predominant. In addition, blaSHV gene was the most common ESBL gene detected in the confirmed ESBL-producing E. coli isolates.

Extended-spectrum β-lactamase producing E. coli and K. pneumoniae is a serious threat to the patients. These organisms are major extended spectrum beta lactamase (ESBL) producers. The objective of this study was to determine the prevalence of Extended spectrum β- lactamase producing strains of Escherichia coli and Klebsiella spp isolates from the urine sample of children visiting International Friendship Children Hospital. During the seven months, between June 2016 to December 2016, 1018 mid-stream urine samples(MSU) were collected from patients suspected of having UTI. The samples were investigated by conventional semi-quantitative culture technique and identification of E. coli and Klebsiella spp. was done by microscopy and biochemical test. Antibiotic susceptibility test of isolates was performed by modified Kirby Bauer Disc diffusion test. ESBL screening test was done by using 3rd generation Cephalosporin and confirmation done by combination disc diffusion method. Out of total 1018 MSU samples investigated, 200(19.64%) isolates of E. coli and 28(2.7%) isolates of Klebsiella spp. making a total of 228(22.39%) were found to cause significant bacteriuria. 76(33.33%) isolates, from those causing significant bacteriuria, were Multi-drug resistant organisms. Out of 228 isolates, 54(23.68%) were ESBL producers, that includes 51(25.5%) Escherichia coli and 3(12.5%) Klebsiella pneumoniae. ESBL producers were more common in in-patient (36.17%) than out-patient (20.44%). Most of the ESBL producers were resistance to amoxicillin, followed by Cotrimoxazole and Ciprofloxacin respectively. They were highly sensitive to Imipenem, Tigecycline, Amikacin, Piperacillin-Tazobactam, and Nitrofurantoin. High prevalence of ESBL producing E. coli and Klebsiella pneumoniae was found among children. Regular and routine monitoring of ESBL producing isolates is essential.Nepal Journal of Biotechnology.

Abstract Background: Resistance of Gram-negative bacteria to antibiotics had increased at an alarming pace over the last two decades. Empirical antibiotic treatment of UTI practice created opportunity for frequent use of antibiotics that resulted in emergence of resistant strains. Extended spectrum beta-lactamase producing Enterobacteriaceae are emerging worldwide and are usually multi-drug resistant; thus, limiting treatment options for these organisms. Hence, it is mandatory to scrutinize the extent of the problem in the study area. Objective: We investigated the prevalence and correlates of extended spectrum beta-lactamase producing Enterobacteriaceae and their antibacterial resistance profile among children with urinary tract infection (UTI) at Hawassa University Comprehensive Specialized Hospital. Method: A hospital-based cross sectional study was conducted from February 1-July 30/ 2018. A semi-structured questionnaire was used to collect data from 284 children suspected of UTI. Bacterial species were isolated using standard bacteriological techniques. Antibiotic susceptibility testing was done using Kirby-Bauer disk diffusion method and ESBL production was detected by double disc synergy test. Data entry, cleaning and statistical analysis was done using SPSS version 20. Results: Overall, Enterobacteriaceae accounted for 75% (72/96) of UTI infections. The most frequent Enterobacteriaceae were E. coli , 44.4% (32/72) and K. pneumoniae , 27.8% (20/72). Overall, ESBL-producers within Enterobacteriaceae accounted for 41.7% (30/72) and magnitude of multi-drug resistance level was 86.1% (62/72). ESBL producing K. pneumoniae and E. coli accounted for 70% (14/20) and 37.5% (12/32), respectively of all the respective isolates. Previous UTI within the past 12 month (AOR= 0.08, 95% CI (0.01-0.57) and medium family wealth index (AOR = 0.03, 95% CI (0.00-0.27) were associated with infection of ESBL-producing Enterobacteriaceae . Conclusion: ESBL producing Enterobacteriaceae were prevalent among UTI cases; where E. coli and K. pneumoniae were the major isolated resistant strains that contributed mainly to the problem. Majority of Enterobacteriaceae isolated were resistant to commonly prescribed drugs. Key words : ESBL, Antimicrobial Resistance, UTI, Children.
