“…The sensitivity rate of TPZ was 53,12%. In previous researchers have reported sensitive rate TPZ from 57.9 % to 9.2% to E. coli in clinical samples (Ghafur et al,2012;Rugini et al,2015). Our results were similar to Ghafur et al,2012 who also reported that TPZ resistance rate of E. coli 57.9%.…”

Objective: A retrospective analysis of the widely used antibiotics all susceptibility testing results from Escherichia coli cultured from clinical specimens private hospital from (January 2016 to November 2018) was performed. Methods: The VITEK 2 Compact automated microbiology system is designed for automated rapid antimicrobial susceptibility testing and identification of clinically relevant bacteria. Minimum inhibitory concentration (MIC) results previously obtained in recent clinical isolates with well-defined in isolates with well-characterized resistance mechanisms with the microdilution method were re-interpreted for the susceptible, intermediate and resistant categories using the 2018 EUCAST breakpoints. Clinical samples are most commonly isolated from blood, sputum and urine samples. Results: Escherichia coli isolates were highly resistant to ampicillin, cefuroxime and cefixime 79,16%, 60,41% and 58,33% respectively. Resistance rate of ceftriaxon was showed in 52,08%. When we compared to resistance of trimethoprim/sulfamethoxazole, Escherichia coli isolates showed 51,04% resistance rate. When it comes to the most sensitive antibiotics, sensitivity rate of fosfomycin, nitrofurantoin, ertapenem, imipenem, meropenem, gentamicin, and amikacin were 89,58%; 91,66%; 93,75%; 93,75%; 94,79%; 83,33%; 84,37% respectively. Conclusion: Considering the antibiogram, fosfomycin, nitrofurantoin, ertapenem, imipenem, meropenem, gentamicin and amikacin should be preferred drugs for E. coli infection isolated from clinical samples.

“…ESBL positive isolates tested in this study showed relatively lower resistance to Nitrofurantoin, a relatively active agent against both ESBL positive and ESBL negative. Similar study results were reported from Kenya [39] and Brazil [40]. This may be due to low prescription of this drug by physicians and therefore, nitrofurantoin remains active for treatment of non-life-threatening urinary tract infections [39].…”

Background Extended-spectrum beta-lactamases (ESBL) producing Enterobacteriaceae are prevalent worldwide and they are unique challenges for treatment and control of bacterial infectious diseases. ESBL genes not only confer resistance to oximino-cephalosporins and aztreonum but also, they are multidrug-resistant to other commonly available antimicrobial agents used in clinical practice.Objective To determine the prevalence and antimicrobial susceptibility profile of ESBL producing Enterobacteriaceae isolated from clinical samples referred to the national clinical bacteriology and mycology reference laboratory.Materials and Methods A cross-sectional study was conducted on Enterobacteriaceae culture- positive clinical samples that were referred to the national bacteriology and mycology reference laboratory from August 2018 to July 2019. Bacterial isolation was performed according to the inoculation and incubation conditions of each clinical specimen and identifications of the isolates were performed using standardized biochemical tests for gram-negative bacteria. Antimicrobial susceptibility profiles of these cultures were determined using the disk diffusion method on Muller Hinton agar according to the recommendation by Clinical and Laboratory Standard Institute (CLSI). ESBL production was detected using CLSI Screening and confirmation test. A double-disk synergy test was used for confirmation.Results Out of 371 culture positive for Enterobacteriaceae , 240 (64.7%) were positive for ESBL production, and the most prevalent species were Klebsiella sp 131(54.6%) followed by E. coli 79 (32.9%). Of 131 ESBL positive Klebsiella spp, 95 (72.5%) were obtained from blood samples and among 79 E. coli isolates, 51 (64.6%) of the strains were isolated from urine samples. All ESBL positive isolates were resistant to ampicillin and all generation of cephalosporins. In addition, 100% of them were multidrug resistant. There were also high proportions of resistant ESBL positive isolates to other classes of antimicrobial agents. Less resistance rates were documented for carbapenems drugs and amikacin from the class of aminoglycosides.Conclusion ESBL producing Enterobacteriaceae we reported in this study was not only highly prevalent but also they are multidrug resistant to most clinically available antimicrobial agents including carbapenems. Therefore, public awareness and regular monitoring
