Authors: Bader MS, Loeb M, Leto D, Brooks AA Abstract Urinary tract infections (UTIs) caused by antibiotic- resistant Gram-negative bacteria are a growing concern due to limited treatment options. Knowledge of the common uropathogens in addition to local susceptibility patterns is essential in determining appropriate empiric antibiotic therapy of UTIs. The recommended first-line empiric antibiotic therapy for acute uncomplicated bacterial cystitis in otherwise healthy adult nonpregnant females is a 5-day course of nitrofurantion, a 3-g single dose of fosfomycin tromethamine, or a 5-day course of pevmecillinam. High...

ConclusionIt is concluded that NIT resistance in the studied NIT-RE. coli isolates was mainly mediated by nfsA and nfsB alterations.

Abstract Multidrug resistance is one of the top three threats to global public health. Understanding resistance of bacteria is important to help decrease resistance and improve the development of novel antimicrobial agents or other alternative tools to combat public health challenges. Thus, the goal of this study was to investigate the vancomycin and florfenicol resistance genes of five E. faecalis and 15 E. faecium isolated from patients with urinary tract infections. There were 20 Enterococcus obtained from the library collection of randomly selected private hospitals located in the city of El Qanater El Khayrey...

ConclusionsThe effectiveness of COL alone in vitro and in vivo suggested that intravenous CMS will be an effective and available therapeutic strategy for UTI due to MDR gram-negative pathogens. In-depth in vitro tests demonstrated that COL combined with DOR could be an attractive option, especially when COL MIC of the pathogen is ≥ 1 μg/ml.

Conclusions: The genotyping allowed identifying the serogroup in many of the strains that could not be typed by traditional serology. The strains carried virulence genes and were multidrug-resistant in both, commensal and virulent phylogroups. Our findings revealed that, in addition to the classical UPEC serogroups, there are pathogenic serogroups not reported yet.

ConclusionsThese results raise concern about epidemiological surveillance related to colonisation of patients discharged from hospitals in order to prevent both the occurrence and spread of resistant bacterial infections in the community.

Conclusion: New carbapenem/βLI combinations may be viable alternatives to antimicrobial combination therapy as they displayed high efficacy in vitro and in vivo. Meropenem/Avibactam and Meropenem/Relebactam should be tested on larger sample sizes with different carbapenemases before progressing further in its preclinical development. Introduction Carbapenem resistant Gram-negative bacteria have been gradually increasing in prevalence in recent years. In the United States, the latest CDC Antibiotic Resistance Threat Report indicates that Carbapenem-Resistant Enterobacteriaceae (CREs) are responsible for 9,000 a...

In conclusion, we unraveled a mechanism of immune evasion of Kpn KPC ST258, which may contribute to design more effective strategies for the treatment of these multi-resistant bacterial infections. Introduction Klebsiella pneumoniae (Kpn) is a Gram-negative pathogen causing a wide range of infections from urinary tract infections to pneumonia. Kpn is a member of the so-called ESKAPE group of microorganisms, a term that emphasizes the fact that they effectively “escape” the effects of antibacterial drugs (1). Antimicrobial resistance is a significant problem for the treatment of infectious diseases caused ...
