“…The inappropriate and indiscriminate use of broad-spectrum antibiotics and prolonged hospital stay are key etiological factors associated with MDR infections ( Prestinaci et al, 2015 ). In our study, 40.4% of E. coli produced ESBLs, whereas other publications reported 25.2%; 35.7, 46.0, and 52–67% ( Gharavi et al, 2021 ; Huang et al, 2022 ; Naushad et al, 2022 ; Sadeghi et al, 2022 ). ESBL producers hydrolyze and eliminate the majority of broad-spectrum beta-lactam antibiotics, increasing morbidity and mortality ( Mahmud et al, 2020 ).…”

Urinary tract infection (UTI) is a common infectious disease that affects men and women. It is a significant health concern due to multidrug-resistant (MDR) organisms. Therefore, it is necessary to have a current understanding of the antibiotic susceptibility (AS) pattern of uropathogens to manage UTI effectively. Since the bacterial pathogen causing UTI and its AS vary with time and place, the prevailing AS pattern of the causative agents are essential for empirical antibiotic therapy. This study aims to determine the prevalence and AS of uropathogens isolated from UTI patients in the eastern part of Northern India. The study was carried out between November 2018 and December 2019. Clean catch midstream urine samples were collected and processed using standard guidelines for microbiological procedures. Positive microbiological cultures were found in 333 of the 427 patients, where 287 were gram-negative bacteria (GNB), and 46 were gram-positive bacteria (GPB). Females had a higher prevalence of UTI (60.7%) than males (39.3%) (p = 0.00024). The most susceptible age group in females was 18–50 years as compared to males, whereas at the age of 51–80 years and >80 years males were more susceptible than females (p = 0.053). The most prevalent pathogen identified were Escherichia coli (55.0%), followed by Proteus sp. (6.9%), Klebsiella pneumoniae (6.6%), Pseudomonas aeruginosa (6.3%), of which 96.0% were MDR bacteria. The susceptibility pattern of our study also revealed that amikacin, gentamycin and imipenem were the most effective drugs against GNB. In contrast, nitrofurantoin, vancomycin, and chloramphenicol were the most effective drugs against GPB. According tothe findings, MDR pathogens are very much prevalent. Since UTI is one of the most frequent bacterial diseases, proper management necessitates extensive investigation and implementation of antibiotic policy based on AS patterns for a particular region.

“…The prevalence of ESBL-producing bacterial strains among isolated organisms has progressively increased over the past decades [12,16]. In addition, due to cross-resistance to other antimicrobial agents, the therapeutic options in UTIs caused by ESBL-producing microbes are limited, which makes the treatment more complex and the use of broad-spectrum antibiotics expensive [17][18][19][20][21]. Because of this global rise in MDR over time, the significant difference in antimicrobial susceptibility in different geographical regions, the prevalence of the ESBL strain among clinical isolates, and the routine assessment of the antimicrobial susceptibility pattern, resistance surveillance at local, national, and international levels is of paramount importance to facilitate the selection of empiric UTIs therapy.…”

Background: To explore the prevalence of urinary tract infections (UTIs) among female patients in the Najran region of Saudi Arabia and determine their antimicrobial resistance pattern. Methods: This study was conducted on 136 urine samples collected from outpatient departments (OPDs) of the different government hospitals in the Najran region of Saudi Arabia. Over one year, the results of susceptibility testing reports of outpatient midstream urine samples from three government hospitals were prospectively evaluated. Results: Of 136 urine samples, only 123 (90.45%) were found to show significant growth for UTIs, from which 23 different uropathogens were identified. Escherichia coli (58.5%) was the most commonly isolated organism, followed by Klebsiella pneumoniae (8.1%). The isolated microorganism showed increased resistance patterns from 3.3% to 62.6%, with an overall resistance of 27.19%. Meropenem was the most effective antimicrobial, followed by amikacin and ertapenem (0.47%, 0.91%, and 1.5% resistance, respectively). At the same time, ampicillin and cephazolin were the least (62.6% and 59.5% resistance, respectively) effective. Overall, eleven (8.94%) uropathogens isolates were ESBLs, among which there were eight (6.5%) Escherichia coli, one (0.81%) Klebsiella pneumoniae, one (0.81%) Klebsiella oxytoca, and one (0.81%) Citrobacter amalonaticus. Conclusions: E. coli remains the most commonly isolated causative uropathogens, followed by Klebsiella species. The prevalence of pathogenic E. coli and Klebsiella species underscores the importance of developing cost-effective, precise, and rapid identification systems to minimize public exposure to uropathogens. Antibiotic susceptibility data revealed that most of the isolates were resistant to the majority of the antibiotics. The patients with UTIs in the Najran region of Saudi Arabia are at a high risk of antibiotic resistance, leading to significant problems in outpatient department (OPD) treatment outcomes and raising the alarm for the physician to change their empiric treatment.

Background and Objectives: Prevalence of extended spectrum β-lactamase (ESBL) leads to the development of antibi- otic resistance and mortality in burn patients. One of the alternative strategies for controlling ESBL bacterial infections is clinical trials of bacteriophage therapy. The aim of this study was to isolate and characterize specific bacteriophages against ESBL-producing Klebsiella pneumoniae in patients with burn ulcers. Materials and Methods: Clinical samples were isolated from the hospitalized patient in burn medical centers, Iran. Bio- chemical screenings and 16S rRNA gene sequencing were determined. The phages were isolated from municipal sewerage treatment plants, Isfahan, Iran. TEM and FESEM, adsorption velocity, growth curve, host range, and the viability of the phage particles as well as proteomics and enzyme digestion patterns were examined. Results: The results showed that Klebsiella pneumoniae Iaufa_lad2 (GenBank accession number: MW836954) was con- firmed as an ESBL-producing strain using combined disk method. This bacterium showed significant sensitivity to three phages including PɸBw-Kp1, PɸBw-Kp2, and PɸBw-Kp3. Morphological characterization demonstrated that the phage PɸBw-Kp3 to the Siphoviridae family (lambda-like phages) and both phages PɸBw-Kp1 and ɸBw-Kp2 to the Podoviridae family (T1-like phages). The isolated bacteriophages had a large burst size, thermal and pH viability and efficient adsorption rate to the host cells. Conclusion: In present study, the efficacy of bacteriophages against ESBL pathogenic bacterium promises a remarkable achievement for phage therapy. It seems that, these isolated bacteriophages, in the form of phage cocktails, had a strong an- tibacterial impacts and a broad-spectrum strategy against ESBL-producing Klebsiella pneumoniae isolated from burn ulcers.
