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.

AbstractObjectiveTo identify patterns of resistance against quinolones in various uropathogens in urinary tract infections in the population of the Toluca valley, MexicoIntroductionQuinolones are antibiotics with a spectrum of activity for both gram-positives and gram-negatives and are antibiotics used for the empirical treatment of urinary tract infections. Recently, a high index of resistance to quinolones has been reported due to different mechanisms on the part of bacteria, however the one that has taken the greatest importance is the presence of extended spectrum beta-lactamasesMethods155 samples were collected from patients with suspected urinary tract infection without exclusion criteria such as age or gender. Automated equipment was used for the identification of the etiological agent and sensitivity tests to quinolones.ResultsThe results positives were divided to evaluate which of the two antibiotics studied had greater resistance. For ciprofloxacin there are 27 resistant strains 37%, 1 strain with intermediate resistance 1% and 45 susceptible strains 62%. For levofloxacin 26 strains are resistant 36%, 41 strains are sensitive 56% and 6 strains show intermediate sensitivity 8%.ConclusionDifferent microorganisms, both gram-positive and gram-negative, were isolated and it can be observed that gram-negative strains are the ones with the greatest resistance against quinolones, mainly Escherichia coli, which produces extended-spectrum beta-lactamases, in the case of gram-positive resistance patterns are variable with a tendency towards sensitivity.

Antibiotic Resistance Patterns

Extended spectrum beta-lactamases (ESBL) in Klebsiella pneumoniae isolates have led to increased antibiotic resistance and mortality in patients. Therefore, the present study was performed to investigate the susceptibility and antibiotic resistance patterns of ESBL- producing K. pneumoniae strains isolated from patients referred to Zanjan hospitals.
